+# Angular Ngrx Best Practices
+
+> Use with the core `angular-best-practices` skill.
+
+---
+
+## 1. NgRx State Management
+
+**Impact: HIGH** (Global state)
+
+### 1.1 Keep Reducers Pure
+
+**Impact: HIGH** (Predictable state, testable, time-travel debugging)
+
+Reducers must be pure functions: no side effects, no HTTP calls, no subscriptions. Only compute new state from action and current state. Move side effects to Effects.
+
+**Example:**
+
+```typescript
+on(UsersActions.load, (state) => ({ ...state, loading: true }));
+// HTTP call goes in UsersEffects
+```
+
+### 1.2 Use Feature Selectors
+
+**Impact: MEDIUM** (Memoized selection, better performance)
+
+Use `createFeatureSelector` and `createSelector` for memoized state selection. Selectors only recompute when their inputs change.
+
+**Example:**
+
+```typescript
+const selectCounterState = createFeatureSelector<CounterState>('counter');
+export const selectCount = createSelector(selectCounterState, (s) => s.count);
+```

+description: Create modern Angular standalone components following v20+ best practices. Use for building UI components with signal-based inputs/outputs, OnPush change detection, host bindings, content projection, and lifecycle hooks. Triggers on component creation, refactoring class-based inputs to signals, adding host bindings, or implementing accessible interactive components.
+---
+
+# Angular Component
+
+Create standalone components for Angular v20+. Components are standalone by default—do NOT set `standalone: true`.
+
+## Component Structure
+
+```typescript
+import { Component, ChangeDetectionStrategy, input, output, computed } from '@angular/core';
+
+@Component({
+    selector: 'app-user-card',
+    changeDetection: ChangeDetectionStrategy.OnPush,
+    host: {
+        'class': 'user-card',
+        '[class.active]': 'isActive()',
+        '(click)': 'handleClick()',
+    },
+    template: `
+        <img
+            [src]="avatarUrl()"
+            [alt]="name() + ' avatar'" />
+        <h2>{{ name() }}</h2>
+        @if (showEmail()) {
+            <p>{{ email() }}</p>
+        }
+    `,
+    styles: `
+        :host {
+            display: block;
+        }
+        :host.active {
+            border: 2px solid blue;
+        }
+    `,
+})
+export class UserCard {
+    // Required input
+    name = input.required<string>();
+
+    // Optional input with default
+    email = input<string>('');
+    showEmail = input(false);
+
+    // Input with transform
+    isActive = input(false, { transform: booleanAttribute });
+
+    // Computed from inputs
+    avatarUrl = computed(() => `https://api.example.com/avatar/${this.name()}`);
+
+    // Output
+    selected = output<string>();
+
+    handleClick() {
+        this.selected.emit(this.name());
+    }
+}
+```
+
+## Signal Inputs
+
+```typescript
+// Required - must be provided by parent
+name = input.required<string>();
+
+// Optional with default value
+count = input(0);
+
+// Optional without default (undefined allowed)
+label = input<string>();
+
+// With alias for template binding
+size = input('medium', { alias: 'buttonSize' });
+
+// With transform function
+disabled = input(false, { transform: booleanAttribute });
+value = input(0, { transform: numberAttribute });
+```
+
+## Signal Outputs
+
+```typescript
+import { output, outputFromObservable } from '@angular/core';
+
+// Basic output
+clicked = output<void>();
+selected = output<Item>();
+
+// With alias
+valueChange = output<number>({ alias: 'change' });
+
+// From Observable (for RxJS interop)
+scroll$ = new Subject<number>();
+scrolled = outputFromObservable(this.scroll$);
+
+// Emit values
+this.clicked.emit();
+this.selected.emit(item);
+```
+
+## Host Bindings
+
+Use the `host` object in `@Component`—do NOT use `@HostBinding` or `@HostListener` decorators.
+
+```typescript
+@Component({
+    selector: 'app-button',
+    host: {
+        // Static attributes
+        'role': 'button',
+
+        // Dynamic class bindings
+        '[class.primary]': 'variant() === "primary"',
+        '[class.disabled]': 'disabled()',
+
+        // Dynamic style bindings
+        '[style.--btn-color]': 'color()',
+
+        // Attribute bindings
+        '[attr.aria-disabled]': 'disabled()',
+        '[attr.tabindex]': 'disabled() ? -1 : 0',
+
+        // Event listeners
+        '(click)': 'onClick($event)',
+        '(keydown.enter)': 'onClick($event)',
+        '(keydown.space)': 'onClick($event)',
+    },
+    template: `<ng-content />`,
+})
+export class Button {
+    variant = input<'primary' | 'secondary'>('primary');
+    disabled = input(false, { transform: booleanAttribute });
+    color = input('#007bff');
+
+    clicked = output<void>();
+
+    onClick(event: Event) {
+        if (!this.disabled()) {
+            this.clicked.emit();
+        }
+    }
+}
+```
+
+## Content Projection
+
+```typescript
+@Component({
+    selector: 'app-card',
+    template: `
+        <header>
+            <ng-content select="[card-header]" />
+        </header>
+        <main>
+            <ng-content />
+        </main>
+        <footer>
+            <ng-content select="[card-footer]" />
+        </footer>
+    `,
+})
+export class Card {}
+
+// Usage:
+// <app-card>
+//   <h2 card-header>Title</h2>
+//   <p>Main content</p>
+//   <button card-footer>Action</button>
+// </app-card>
+```
+
+## Lifecycle Hooks
+
+```typescript
+import { OnDestroy, OnInit, afterNextRender, afterRender } from '@angular/core';
+
+export class My implements OnInit, OnDestroy {
+    constructor() {
+        // For DOM manipulation after render (SSR-safe)
+        afterNextRender(() => {
+            // Runs once after first render
+        });
+
+        afterRender(() => {
+            // Runs after every render
+        });
+    }
+
+    ngOnInit() {
+        /* Component initialized */
+    }
+    ngOnDestroy() {
+        /* Cleanup */
+    }
+}
+```
+
+## Accessibility Requirements
+
+Components MUST:
+
+- Pass AXE accessibility checks
+- Meet WCAG AA standards
+- Include proper ARIA attributes for interactive elements
+- Support keyboard navigation
+- Maintain visible focus indicators
+
+```typescript
+@Component({
+    selector: 'app-toggle',
+    host: {
+        'role': 'switch',
+        '[attr.aria-checked]': 'checked()',
+        '[attr.aria-label]': 'label()',
+        'tabindex': '0',
+        '(click)': 'toggle()',
+        '(keydown.enter)': 'toggle()',
+        '(keydown.space)': 'toggle(); $event.preventDefault()',
+    },
+    template: `<span class="toggle-track"><span class="toggle-thumb"></span></span>`,
+})
+export class Toggle {
+    label = input.required<string>();
+    checked = input(false, { transform: booleanAttribute });
+    checkedChange = output<boolean>();
+
+    toggle() {
+        this.checkedChange.emit(!this.checked());
+    }
+}
+```
+
+## Template Syntax
+
+Use native control flow—do NOT use `*ngIf`, `*ngFor`, `*ngSwitch`.
+
+```html
+<!-- Conditionals -->
+@if (isLoading()) {
+<app-spinner />
+} @else if (error()) {
+<app-error [message]="error()" />
+} @else {
+<app-content [data]="data()" />
+}
+
+<!-- Loops -->
+@for (item of items(); track item.id) {
+<app-item [item]="item" />
+} @empty {
+<p>No items found</p>
+}
+
+<!-- Switch -->
+@switch (status()) { @case ('pending') { <span>Pending</span> } @case ('active') { <span>Active</span> } @default { <span>Unknown</span> } }
+```
+
+## Class and Style Bindings
+
+Do NOT use `ngClass` or `ngStyle`. Use direct bindings:
+
+```html
+<!-- Class bindings -->
+<div [class.active]="isActive()">Single class</div>
+<div [class]="classString()">Class string</div>
+
+<!-- Style bindings -->
+<div [style.color]="textColor()">Styled text</div>
+<div [style.width.px]="width()">With unit</div>
+```
+
+## Images
+
+Use `NgOptimizedImage` for static images:
+
+```typescript
+import { NgOptimizedImage } from '@angular/common';
+
+@Component({
+    imports: [NgOptimizedImage],
+    template: `
+        <img
+            ngSrc="/assets/hero.jpg"
+            width="800"
+            height="600"
+            priority />
+        <img
+            width="200"
+            height="200"
+            [ngSrc]="imageUrl()" />
+    `,
+})
+export class Hero {
+    imageUrl = input.required<string>();
+}
+```

+
+## Model Inputs (Two-Way Binding)
+
+For two-way binding with `[(value)]` syntax:
+
+```typescript
+import { Component, model } from '@angular/core';
+
+@Component({
+    selector: 'app-slider',
+    host: {
+        '(input)': 'onInput($event)',
+    },
+    template: `
+        <input
+            type="range"
+            [value]="value()"
+            [min]="min()"
+            [max]="max()" />
+        <span>{{ value() }}</span>
+    `,
+})
+export class Slider {
+    // Model creates both input and output
+    value = model(0);
+    min = input(0);
+    max = input(100);
+
+    onInput(event: Event) {
+        const target = event.target as HTMLInputElement;
+        this.value.set(Number(target.value));
+    }
+}
+
+// Usage: <app-slider [(value)]="sliderValue" />
+```
+
+Required model:
+
+```typescript
+value = model.required<number>();
+```
+
+## View Queries
+
+Query elements and components in the template:
+
+```typescript
+import { Component, viewChild, viewChildren, ElementRef } from '@angular/core';
+
+@Component({
+    selector: 'app-gallery',
+    template: `
+        <div
+            #container
+            class="gallery">
+            @for (image of images(); track image.id) {
+                <app-image-card [image]="image" />
+            }
+        </div>
+    `,
+})
+export class Gallery {
+    images = input.required<Image[]>();
+
+    // Query single element
+    container = viewChild.required<ElementRef<HTMLDivElement>>('container');
+
+    // Query single component (optional)
+    firstCard = viewChild(ImageCard);
+
+    // Query all matching components
+    allCards = viewChildren(ImageCard);
+}
+```
+
+## Content Queries
+
+Query projected content:
+
+```typescript
+import { Component, contentChild, contentChildren, effect, signal } from '@angular/core';
+
+@Component({
+    selector: 'app-tabs',
+    template: `
+        <div class="tab-headers">
+            @for (tab of tabs(); track tab.label()) {
+                <button
+                    [class.active]="tab === activeTab()"
+                    (click)="selectTab(tab)">
+                    {{ tab.label() }}
+                </button>
+            }
+        </div>
+        <div class="tab-content">
+            <ng-content />
+        </div>
+    `,
+})
+export class Tabs {
+    // Query all projected Tab children
+    tabs = contentChildren(Tab);
+
+    // Query single projected element
+    header = contentChild('tabHeader');
+
+    activeTab = signal<Tab | undefined>(undefined);
+
+    constructor() {
+        // Set first tab as active when tabs are available
+        effect(() => {
+            const firstTab = this.tabs()[0];
+            if (firstTab && !this.activeTab()) {
+                this.activeTab.set(firstTab);
+            }
+        });
+    }
+
+    selectTab(tab: Tab) {
+        this.activeTab.set(tab);
+    }
+}
+
+@Component({
+    selector: 'app-tab',
+    template: `<ng-content />`,
+    host: {
+        '[class.active]': 'isActive()',
+        '[style.display]': 'isActive() ? "block" : "none"',
+    },
+})
+export class Tab {
+    label = input.required<string>();
+    isActive = input(false);
+}
+```
+
+## Dependency Injection in Components
+
+Use `inject()` function instead of constructor injection:
+
+```typescript
+import { Component, inject } from '@angular/core';
+import { Router } from '@angular/router';
+
+@Component({
+    selector: 'app-dashboard',
+    template: `...`,
+})
+export class Dashboard {
+    private router = inject(Router);
+    private userService = inject(User);
+    private config = inject(APP_CONFIG);
+
+    // Optional injection
+    private analytics = inject(Analytics, { optional: true });
+
+    // Self-only injection
+    private localService = inject(Local, { self: true });
+
+    navigateToProfile() {
+        this.router.navigate(['/profile']);
+    }
+}
+```
+
+## Component Communication Patterns
+
+### Parent to Child (Inputs)
+
+```typescript
+// Parent
+@Component({
+    template: `<app-child
+        [data]="parentData()"
+        [config]="config" />`,
+})
+export class Parent {
+    parentData = signal({ name: 'Test' });
+    config = { theme: 'dark' };
+}
+
+// Child
+@Component({ selector: 'app-child' })
+export class Child {
+    data = input.required<Data>();
+    config = input<Config>();
+}
+```
+
+### Child to Parent (Outputs)
+
+```typescript
+// Child
+@Component({
+    selector: 'app-child',
+    template: `<button (click)="save()">Save</button>`,
+})
+export class Child {
+    saved = output<Data>();
+
+    save() {
+        this.saved.emit({ id: 1, name: 'Item' });
+    }
+}
+
+// Parent
+@Component({
+    template: `<app-child (saved)="onSaved($event)" />`,
+})
+export class Parent {
+    onSaved(data: Data) {
+        console.log('Saved:', data);
+    }
+}
+```
+
+### Shared Service Pattern
+
+```typescript
+// Shared state service
+@Injectable({ providedIn: 'root' })
+export class Cart {
+    private items = signal<CartItem[]>([]);
+
+    readonly items$ = this.items.asReadonly();
+    readonly total = computed(() => this.items().reduce((sum, item) => sum + item.price, 0));
+
+    addItem(item: CartItem) {
+        this.items.update((items) => [...items, item]);
+    }
+
+    removeItem(id: string) {
+        this.items.update((items) => items.filter((i) => i.id !== id));
+    }
+}
+
+// Component A
+@Component({ template: `<button (click)="add()">Add</button>` })
+export class Product {
+    private cart = inject(Cart);
+    product = input.required<Product>();
+
+    add() {
+        this.cart.addItem({ ...this.product(), quantity: 1 });
+    }
+}
+
+// Component B
+@Component({ template: `<span>Total: {{ cart.total() }}</span>` })
+export class CartSummary {
+    cart = inject(Cart);
+}
+```
+
+## Dynamic Components
+
+Using `@defer` for lazy loading:
+
+```typescript
+@Component({
+    template: `
+        @defer (on viewport) {
+            <app-heavy-chart [data]="chartData()" />
+        } @placeholder {
+            <div class="chart-placeholder">Loading chart...</div>
+        } @loading (minimum 500ms) {
+            <app-spinner />
+        } @error {
+            <p>Failed to load chart</p>
+        }
+    `,
+})
+export class Dashboard {
+    chartData = input.required<ChartData>();
+}
+```
+
+Defer triggers:
+
+- `on viewport` - When element enters viewport
+- `on idle` - When browser is idle
+- `on interaction` - On user interaction (click, focus)
+- `on hover` - On mouse hover
+- `on immediate` - Immediately after non-deferred content
+- `on timer(500ms)` - After specified delay
+- `when condition` - When expression becomes true
+
+```typescript
+@Component({
+    template: `
+        @defer (on interaction; prefetch on idle) {
+            <app-comments [postId]="postId()" />
+        } @placeholder {
+            <button>Load Comments</button>
+        }
+    `,
+})
+export class Post {
+    postId = input.required<string>();
+}
+```
+
+## Attribute Directives on Components
+
+```typescript
+@Directive({
+    selector: '[appHighlight]',
+    host: {
+        '[style.backgroundColor]': 'color()',
+    },
+})
+export class Highlight {
+    color = input('yellow', { alias: 'appHighlight' });
+}
+
+// Usage on component

+description: Implement dependency injection in Angular v20+ using inject(), injection tokens, and provider configuration. Use for service architecture, providing dependencies at different levels, creating injectable tokens, and managing singleton vs scoped services. Triggers on service creation, configuring providers, using injection tokens, or understanding DI hierarchy.
+---
+
+# Angular Dependency Injection
+
+Configure and use dependency injection in Angular v20+ with `inject()` and providers.
+
+## Basic Injection
+
+### Using inject()
+
+Prefer `inject()` over constructor injection:
+
+```typescript
+import { Component, inject } from '@angular/core';
+import { HttpClient } from '@angular/common/http';
+import { User } from './user.service';
+
+@Component({
+    selector: 'app-user-list',
+    template: `...`,
+})
+export class UserList {
+    // Inject dependencies
+    private http = inject(HttpClient);
+    private userService = inject(User);
+
+    // Can use immediately
+    users = this.userService.getUsers();
+}
+```
+
+### Injectable Services
+
+```typescript
+import { Injectable, inject, signal } from '@angular/core';
+import { HttpClient } from '@angular/common/http';
+
+@Injectable({
+    providedIn: 'root', // Singleton at root level
+})
+export class User {
+    private http = inject(HttpClient);
+
+    private users = signal<User[]>([]);
+    readonly users$ = this.users.asReadonly();
+
+    async loadUsers() {
+        const users = await firstValueFrom(this.http.get<User[]>('/api/users'));
+        this.users.set(users);
+    }
+}
+```
+
+## Provider Scopes
+
+### Root Level (Singleton)
+
+```typescript
+// Recommended: providedIn
+@Injectable({
+    providedIn: 'root',
+})
+export class Auth {}
+
+// Alternative: in app.config.ts
+export const appConfig: ApplicationConfig = {
+    providers: [Auth],
+};
+```
+
+### Component Level (Instance per Component)
+
+```typescript
+@Component({
+    selector: 'app-editor',
+    providers: [EditorState], // New instance for each component
+    template: `...`,
+})
+export class Editor {
+    private editorState = inject(EditorState);
+}
+```
+
+### Route Level
+
+```typescript
+export const routes: Routes = [
+    {
+        path: 'admin',
+        providers: [Admin], // Shared within this route tree
+        children: [
+            { path: '', component: AdminDashboard },
+            { path: 'users', component: AdminUsers },
+        ],
+    },
+];
+```
+
+## Injection Tokens
+
+### Creating Tokens
+
+```typescript
+import { InjectionToken } from '@angular/core';
+
+// Simple value token
+export const API_URL = new InjectionToken<string>('API_URL');
+
+// Object token
+export interface AppConfig {
+    apiUrl: string;
+    features: {
+        darkMode: boolean;
+        analytics: boolean;
+    };
+}
+
+export const APP_CONFIG = new InjectionToken<AppConfig>('APP_CONFIG');
+
+// Token with factory (self-providing)
+export const WINDOW = new InjectionToken<Window>('Window', {
+    providedIn: 'root',
+    factory: () => window,
+});
+
+export const LOCAL_STORAGE = new InjectionToken<Storage>('LocalStorage', {
+    providedIn: 'root',
+    factory: () => localStorage,
+});
+```
+
+### Providing Token Values
+
+```typescript
+// app.config.ts
+export const appConfig: ApplicationConfig = {
+    providers: [
+        { provide: API_URL, useValue: 'https://api.example.com' },
+        {
+            provide: APP_CONFIG,
+            useValue: {
+                apiUrl: 'https://api.example.com',
+                features: { darkMode: true, analytics: true },
+            },
+        },
+    ],
+};
+```
+
+### Injecting Tokens
+
+```typescript
+@Injectable({ providedIn: 'root' })
+export class Api {
+    private apiUrl = inject(API_URL);
+    private config = inject(APP_CONFIG);
+    private window = inject(WINDOW);
+
+    getBaseUrl(): string {
+        return this.apiUrl;
+    }
+}
+```
+
+## Provider Types
+
+### useClass
+
+```typescript
+// Provide implementation
+{ provide: Logger, useClass: ConsoleLogger }
+
+// Conditional implementation
+{
+  provide: Logger,
+  useClass: environment.production
+    ? ProductionLogger
+    : ConsoleLogger,
+}
+```
+
+### useValue
+
+```typescript
+// Static values
+{ provide: API_URL, useValue: 'https://api.example.com' }
+
+// Configuration objects
+{ provide: APP_CONFIG, useValue: { theme: 'dark', language: 'en' } }
+```
+
+### useFactory
+
+```typescript
+// Factory with dependencies
+{
+  provide: User,
+  useFactory: (http: HttpClient, config: AppConfig) => {
+    return new User(http, config.apiUrl);
+  },
+  deps: [HttpClient, APP_CONFIG],
+}
+
+// Async factory (not recommended - use provideAppInitializer)
+{
+  provide: CONFIG,
+  useFactory: () => fetch('/config.json').then(r => r.json()),
+}
+```
+
+### useExisting
+
+```typescript
+// Alias to existing provider
+{ provide: AbstractLogger, useExisting: ConsoleLogger }
+
+// Multiple tokens pointing to same instance
+providers: [
+  ConsoleLogger,
+  { provide: Logger, useExisting: ConsoleLogger },
+  { provide: ErrorLogger, useExisting: ConsoleLogger },
+]
+```
+
+## Injection Options
+
+### Optional Injection
+
+```typescript
+@Component({...})
+export class My {
+  // Returns null if not provided
+  private analytics = inject(Analytics, { optional: true });
+
+  trackEvent(name: string) {
+    this.analytics?.track(name);
+  }
+}
+```
+
+### Self, SkipSelf, Host
+
+```typescript
+@Component({
+  providers: [Local],
+})
+export class Parent {
+  // Only look in this component's injector
+  private local = inject(Local, { self: true });
+}
+
+@Component({...})
+export class Child {
+  // Skip this component, look in parent
+  private parentService = inject(ParentSvc, { skipSelf: true });
+
+  // Only look up to host component
+  private hostService = inject(Host, { host: true });
+}
+```
+
+## Multi Providers
+
+Collect multiple values for same token:
+
+```typescript
+// Token for multiple validators
+export const VALIDATORS = new InjectionToken<Validator[]>('Validators');
+
+// Provide multiple values
+providers: [
+    { provide: VALIDATORS, useClass: RequiredValidator, multi: true },
+    { provide: VALIDATORS, useClass: EmailValidator, multi: true },
+    { provide: VALIDATORS, useClass: MinLengthValidator, multi: true },
+];
+
+// Inject as array
+@Injectable()
+export class Validation {
+    private validators = inject(VALIDATORS); // Validator[]
+
+    validate(value: string): ValidationError[] {
+        return this.validators.map((v) => v.validate(value)).filter(Boolean);
+    }
+}
+```
+
+### HTTP Interceptors (Multi Provider)
+
+```typescript
+// Interceptors use multi providers internally
+export const appConfig: ApplicationConfig = {
+    providers: [provideHttpClient(withInterceptors([authInterceptor, loggingInterceptor, errorInterceptor]))],
+};
+```
+
+## App Initializers
+
+Run async code before app starts using `provideAppInitializer`:
+
+```typescript
+import { provideAppInitializer, inject } from '@angular/core';
+
+export const appConfig: ApplicationConfig = {
+    providers: [
+        Config,
+        provideAppInitializer(() => {
+            const configService = inject(Config);
+            return configService.loadConfig();
+        }),
+    ],
+};
+```
+
+### Multiple Initializers
+
+```typescript
+providers: [
+    provideAppInitializer(() => {
+        const config = inject(Config);
+        return config.load();
+    }),
+    provideAppInitializer(() => {
+        const auth = inject(Auth);
+        return auth.checkSession();
+    }),
+];
+```
+
+## Environment Injector
+
+Create injectors programmatically:
+
+```typescript
+import { createEnvironmentInjector, EnvironmentInjector, inject } from '@angular/core';
+
+@Injectable({ providedIn: 'root' })
+export class Plugin {
+    private parentInjector = inject(EnvironmentInjector);
+
+    loadPlugin(providers: Provider[]): EnvironmentInjector {
+        return createEnvironmentInjector(providers, this.parentInjector);
+    }
+}
+```
+
+## runInInjectionContext
+
+Run code with injection context:
+
+```typescript
+import { runInInjectionContext, EnvironmentInjector, inject } from '@angular/core';
+
+@Injectable({ providedIn: 'root' })
+export class Utility {
+    private injector = inject(EnvironmentInjector);
+
+    executeWithDI<T>(fn: () => T): T {
+        return runInInjectionContext(this.injector, fn);
+    }
+}
+
+// Usage
+utilityService.executeWithDI(() => {
+    const http = inject(HttpClient);
+    // Use http...
+});
+```

+## Service Patterns
+
+### Facade Service
+
+Combine multiple services into a single API:
+
+```typescript
+@Injectable({ providedIn: 'root' })
+export class ShopFacade {
+    private productService = inject(Product);
+    private cartService = inject(Cart);
+    private orderService = inject(Order);
+
+    // Expose combined state
+    readonly products = this.productService.products;
+    readonly cart = this.cartService.items;
+    readonly cartTotal = this.cartService.total;
+
+    // Unified actions
+    addToCart(productId: string, quantity: number) {
+        const product = this.productService.getById(productId);
+        if (product) {
+            this.cartService.add(product, quantity);
+        }
+    }
+
+    async checkout() {
+        const items = this.cartService.items();
+        const order = await this.orderService.create(items);
+        this.cartService.clear();
+        return order;
+    }
+}
+```
+
+### State Service Pattern
+
+```typescript
+interface UserState {
+    user: User | null;
+    loading: boolean;
+    error: string | null;
+}
+
+@Injectable({ providedIn: 'root' })
+export class UserState {
+    private state = signal<UserState>({
+        user: null,
+        loading: false,
+        error: null,
+    });
+
+    // Selectors
+    readonly user = computed(() => this.state().user);
+    readonly loading = computed(() => this.state().loading);
+    readonly error = computed(() => this.state().error);
+    readonly isAuthenticated = computed(() => this.state().user !== null);
+
+    // Actions
+    setUser(user: User) {
+        this.state.update((s) => ({ ...s, user, loading: false, error: null }));
+    }
+
+    setLoading() {
+        this.state.update((s) => ({ ...s, loading: true, error: null }));
+    }
+
+    setError(error: string) {
+        this.state.update((s) => ({ ...s, loading: false, error }));
+    }
+
+    clear() {
+        this.state.set({ user: null, loading: false, error: null });
+    }
+}
+```
+
+### Repository Pattern
+
+```typescript
+// Generic repository interface
+export abstract class Repository<T extends { id: string }> {
+  abstract getAll(): Promise<T[]>;
+  abstract getById(id: string): Promise<T | null>;
+  abstract create(item: Omit<T, 'id'>): Promise<T>;
+  abstract update(id: string, item: Partial<T>): Promise<T>;
+  abstract delete(id: string): Promise<void>;
+}
+
+// HTTP implementation
+@Injectable()
+export class HttpUserRepo extends Repository<User> {
+  private http = inject(HttpClient);
+  private apiUrl = inject(API_URL);
+
+  async getAll(): Promise<User[]> {
+    return firstValueFrom(this.http.get<User[]>(`${this.apiUrl}/users`));
+  }
+
+  async getById(id: string): Promise<User | null> {
+    return firstValueFrom(
+      this.http.get<User>(`${this.apiUrl}/users/${id}`).pipe(
+        catchError(() => of(null))
+      )
+    );
+  }
+
+  async create(user: Omit<User, 'id'>): Promise<User> {
+    return firstValueFrom(this.http.post<User>(`${this.apiUrl}/users`, user));
+  }
+
+  async update(id: string, user: Partial<User>): Promise<User> {
+    return firstValueFrom(this.http.patch<User>(`${this.apiUrl}/users/${id}`, user));
+  }
+
+  async delete(id: string): Promise<void> {
+    await firstValueFrom(this.http.delete(`${this.apiUrl}/users/${id}`));
+  }
+}
+
+// Provide implementation
+{ provide: Repository, useClass: HttpUserRepo }
+```
+
+## Abstract Classes as Tokens
+
+Use abstract classes for better type safety:
+
+```typescript
+// Abstract service definition
+export abstract class Logger {
+  abstract log(message: string): void;
+  abstract error(message: string, error?: Error): void;
+  abstract warn(message: string): void;
+}
+
+// Console implementation
+@Injectable()
+export class ConsoleLog extends Logger {
+  log(message: string) {
+    console.log(`[LOG] ${message}`);
+  }
+
+  error(message: string, error?: Error) {
+    console.error(`[ERROR] ${message}`, error);
+  }
+
+  warn(message: string) {
+    console.warn(`[WARN] ${message}`);
+  }
+}
+
+// Remote implementation
+@Injectable()
+export class RemoteLog extends Logger {
+  private http = inject(HttpClient);
+
+  log(message: string) {
+    this.send('log', message);
+  }
+
+  error(message: string, error?: Error) {
+    this.send('error', message, error);
+  }
+
+  warn(message: string) {
+    this.send('warn', message);
+  }
+
+  private send(level: string, message: string, error?: Error) {
+    this.http.post('/api/logs', { level, message, error: error?.message }).subscribe();
+  }
+}
+
+// Provide based on environment
+{
+  provide: Logger,
+  useClass: environment.production ? RemoteLog : ConsoleLog,
+}
+
+// Inject using abstract class
+@Injectable({ providedIn: 'root' })
+export class User {
+  private logger = inject(Logger);
+
+  createUser(user: UserData) {
+    this.logger.log(`Creating user: ${user.email}`);
+    // ...
+  }
+}
+```
+
+## Hierarchical Injection
+
+### Component Tree Injection
+
+```typescript
+// Parent provides service
+@Component({
+    selector: 'app-form-container',
+    providers: [FormState],
+    template: `
+        <app-form-header />
+        <app-form-body />
+        <app-form-footer />
+    `,
+})
+export class FormContainer {
+    private formState = inject(FormState);
+}
+
+// Children share same instance
+@Component({
+    selector: 'app-form-body',
+    template: `...`,
+})
+export class FormBody {
+    // Gets same instance as parent
+    private formState = inject(FormState);
+}
+
+// Grandchildren also share
+@Component({
+    selector: 'app-form-field',
+    template: `...`,
+})
+export class FormField {
+    // Gets same instance from ancestor
+    private formState = inject(FormState);
+}
+```
+
+### viewProviders vs providers
+
+```typescript
+@Component({
+    selector: 'app-tabs',
+    // providers: Available to component AND content children
+    providers: [TabsSvc],
+
+    // viewProviders: Available to component AND view children only
+    // NOT available to content children (<ng-content>)
+    viewProviders: [InternalTabs],
+
+    template: `
+        <div class="tabs">
+            <ng-content />
+            <!-- Content children can't access viewProviders -->
+        </div>
+    `,
+})
+export class Tabs {}
+```
+
+## Dynamic Providers
+
+### Feature Flags
+
+```typescript
+export const FEATURE_FLAGS = new InjectionToken<FeatureFlags>('FeatureFlags');
+
+interface FeatureFlags {
+  newDashboard: boolean;
+  betaFeatures: boolean;
+  experimentalApi: boolean;
+}
+
+// Load from API
+{
+  provide: FEATURE_FLAGS,
+  useFactory: async () => {
+    const response = await fetch('/api/features');
+    return response.json();
+  },
+}
+
+// Use in components
+@Component({...})
+export class Dashboard {
+  private features = inject(FEATURE_FLAGS);
+
+  showNewDashboard = this.features.newDashboard;
+}
+```
+
+### Platform-Specific Services
+
+```typescript
+export abstract class Storage {
+  abstract get(key: string): string | null;
+  abstract set(key: string, value: string): void;
+  abstract remove(key: string): void;
+}
+
+@Injectable()
+export class BrowserStorage extends Storage {
+  get(key: string) { return localStorage.getItem(key); }
+  set(key: string, value: string) { localStorage.setItem(key, value); }
+  remove(key: string) { localStorage.removeItem(key); }
+}
+
+@Injectable()
+export class ServerStorage extends Storage {
+  private store = new Map<string, string>();
+
+  get(key: string) { return this.store.get(key) ?? null; }
+  set(key: string, value: string) { this.store.set(key, value); }
+  remove(key: string) { this.store.delete(key); }
+}
+
+// Provide based on platform
+import { PLATFORM_ID, isPlatformBrowser } from '@angular/common';
+
+{
+  provide: Storage,
+  useFactory: (platformId: object) => {
+    return isPlatformBrowser(platformId)
+      ? new BrowserStorage()
+      : new ServerStorage();
+  },
+  deps: [PLATFORM_ID],
+}
+```
+
+## Testing with DI
+
+### Mocking Services
+
+```typescript
+describe('UserCmpt', () => {
+    let userServiceSpy: jasmine.SpyObj<User>;
+
+    beforeEach(async () => {
+        userServiceSpy = jasmine.createSpyObj('User', ['getUser', 'updateUser']);
+        userServiceSpy.getUser.and.returnValue(of({ id: '1', name: 'Test' }));
+
+        await TestBed.configureTestingModule({
+            imports: [UserCmpt],
+            providers: [{ provide: User, useValue: userServiceSpy }],
+        }).compileComponents();
+    });
+
+    it('should load user', () => {
+        const fixture = TestBed.createComponent(UserCmpt);
+        fixture.detectChanges();
+
+        expect(userServiceSpy.getUser).toHaveBeenCalled();
+    });
+});
+```
+
+### Overriding Providers
+
+```typescript
+describe('with different config', () => {
+    beforeEach(async () => {
+        await TestBed.configureTestingModule({
+            imports: [App],
+        })
+            .overrideProvider(APP_CONFIG, {
+                useValue: { apiUrl: 'http://test-api.com' },
+            })
+            .compileComponents();
+    });
+});
+```
+
+### Testing Injection Tokens
+
+```typescript
+describe('API_URL token', () => {
+    it('should provide correct URL', () => {
+        TestBed.configureTestingModule({
+            providers: [{ provide: API_URL, useValue: 'https://api.test.com' }],
+        });
+
+        const apiUrl = TestBed.inject(API_URL);
+        expect(apiUrl).toBe('https://api.test.com');
+    });
+});
+```
+
+## DestroyRef and Cleanup
+
+### Automatic Cleanup
+
+```typescript
+import { DestroyRef, inject } from '@angular/core';
+import { takeUntilDestroyed } from '@angular/core/rxjs-interop';
+
+@Component({...})
+export class Data {
+  private destroyRef = inject(DestroyRef);
+  private dataService = inject(DataSvc);
+
+  constructor() {
+    // Auto-unsubscribe when component destroys
+    this.dataService.data$
+      .pipe(takeUntilDestroyed())
+      .subscribe(data => {
+        console.log(data);
+      });
+  }
+
+  // Or use DestroyRef directly
+  ngOnInit() {
+    const subscription = this.dataService.updates$.subscribe();
+
+    this.destroyRef.onDestroy(() => {
+      subscription.unsubscribe();
+      console.log('Cleaned up!');
+    });
+  }
+}
+```
+
+### In Services
+
+```typescript
+@Injectable()
+export class WebSocket {
+    private destroyRef = inject(DestroyRef);
+    private socket: WebSocket | null = null;
+
+    constructor() {
+        this.destroyRef.onDestroy(() => {
+            this.socket?.close();
+        });
+    }
+
+    connect(url: string) {
+        this.socket = new WebSocket(url);
+    }
+}
+```
+
+### takeUntilDestroyed Outside Constructor
+
+```typescript
+@Component({...})
+export class My {
+  private destroyRef = inject(DestroyRef);
+
+  loadData() {
+    // Pass destroyRef when using outside constructor
+    this.http.get('/api/data')
+      .pipe(takeUntilDestroyed(this.destroyRef))
+      .subscribe();
+  }
+}
+```

+
+### assertInInjectionContext
+
+```typescript
+import { assertInInjectionContext, inject } from '@angular/core';
+
+export function injectLogger(): Logger {
+  assertInInjectionContext(injectLogger);
+  return inject(Logger);
+}
+
+// Usage - must be called in injection context
+@Component({...})
+export class My2 {
+  private logger = injectLogger(); // OK
+
+  someMethod() {
+    // injectLogger(); // ERROR - not in injection context
+  }
+}
+```
+
+### Custom inject Functions
+
+```typescript
+// Create reusable injection utilities
+export function injectRouteParam(param: string): Signal<string | null> {
+  assertInInjectionContext(injectRouteParam);
+
+  const route = inject(ActivatedRoute);
+  return toSignal(
+    route.paramMap.pipe(map(params => params.get(param))),
+    { initialValue: null }
+  );
+}
+
+export function injectQueryParam(param: string): Signal<string | null> {
+  assertInInjectionContext(injectQueryParam);
+
+  const route = inject(ActivatedRoute);
+  return toSignal(
+    route.queryParamMap.pipe(map(params => params.get(param))),
+    { initialValue: null }
+  );
+}
+
+// Usage
+@Component({...})
+export class UserCmpt {
+  userId = injectRouteParam('id');
+  tab = injectQueryParam('tab');
+}

+description: Create custom directives in Angular v20+ for DOM manipulation and behavior extension. Use for attribute directives that modify element behavior/appearance, structural directives for portals/overlays, and host directives for composition. Triggers on creating reusable DOM behaviors, extending element functionality, or composing behaviors across components. Note - use native @if/@for/@switch for control flow, not custom structural directives.

+
+# Angular Directives
+
+Create custom directives for reusable DOM manipulation and behavior in Angular v20+.
+
+## Attribute Directives
+
+Modify the appearance or behavior of an element:
+
+```typescript
+import { Directive, input, effect, inject, ElementRef } from '@angular/core';
+
+@Directive({
+    selector: '[appHighlight]',
+})
+export class Highlight {
+    private el = inject(ElementRef<HTMLElement>);
+
+    // Input with alias matching selector
+    color = input('yellow', { alias: 'appHighlight' });
+
+    constructor() {
+        effect(() => {
+            this.el.nativeElement.style.backgroundColor = this.color();
+        });
+    }
+}
+
+// Usage: <p appHighlight="lightblue">Highlighted text</p>
+// Usage: <p appHighlight>Default yellow highlight</p>
+```
+
+### Using host Property
+
+Prefer `host` over `@HostBinding`/`@HostListener`:
+
+```typescript
+@Directive({
+    selector: '[appTooltip]',
+    host: {
+        '(mouseenter)': 'show()',
+        '(mouseleave)': 'hide()',
+        '[attr.aria-describedby]': 'tooltipId',
+    },
+})
+export class Tooltip {
+    text = input.required<string>({ alias: 'appTooltip' });
+    position = input<'top' | 'bottom' | 'left' | 'right'>('top');
+
+    tooltipId = `tooltip-${crypto.randomUUID()}`;
+    private tooltipEl: HTMLElement | null = null;
+    private el = inject(ElementRef<HTMLElement>);
+
+    show() {
+        this.tooltipEl = document.createElement('div');
+        this.tooltipEl.id = this.tooltipId;
+        this.tooltipEl.className = `tooltip tooltip-${this.position()}`;
+        this.tooltipEl.textContent = this.text();
+        this.tooltipEl.setAttribute('role', 'tooltip');
+        document.body.appendChild(this.tooltipEl);
+        this.positionTooltip();
+    }
+
+    hide() {
+        this.tooltipEl?.remove();
+        this.tooltipEl = null;
+    }
+
+    private positionTooltip() {
+        // Position logic based on this.position() and this.el
+    }
+}
+
+// Usage: <button appTooltip="Click to save" position="bottom">Save</button>
+```
+
+### Class and Style Manipulation
+
+```typescript
+@Directive({
+    selector: '[appButton]',
+    host: {
+        'class': 'btn',
+        '[class.btn-primary]': 'variant() === "primary"',
+        '[class.btn-secondary]': 'variant() === "secondary"',
+        '[class.btn-sm]': 'size() === "small"',
+        '[class.btn-lg]': 'size() === "large"',
+        '[class.disabled]': 'disabled()',
+        '[attr.disabled]': 'disabled() || null',
+    },
+})
+export class Button {
+    variant = input<'primary' | 'secondary'>('primary');
+    size = input<'small' | 'medium' | 'large'>('medium');
+    disabled = input(false, { transform: booleanAttribute });
+}
+
+// Usage: <button appButton variant="primary" size="large">Click</button>
+```
+
+### Event Handling
+
+```typescript
+@Directive({
+    selector: '[appClickOutside]',
+    host: {
+        '(document:click)': 'onDocumentClick($event)',
+    },
+})
+export class ClickOutside {
+    private el = inject(ElementRef<HTMLElement>);
+
+    clickOutside = output<void>();
+
+    onDocumentClick(event: MouseEvent) {
+        if (!this.el.nativeElement.contains(event.target as Node)) {
+            this.clickOutside.emit();
+        }
+    }
+}
+
+// Usage: <div appClickOutside (clickOutside)="closeMenu()">...</div>
+```
+
+### Keyboard Shortcuts
+
+```typescript
+@Directive({
+    selector: '[appShortcut]',
+    host: {
+        '(document:keydown)': 'onKeydown($event)',
+    },
+})
+export class Shortcut {
+    key = input.required<string>({ alias: 'appShortcut' });
+    ctrl = input(false, { transform: booleanAttribute });
+    shift = input(false, { transform: booleanAttribute });
+    alt = input(false, { transform: booleanAttribute });
+
+    triggered = output<KeyboardEvent>();
+
+    onKeydown(event: KeyboardEvent) {
+        const keyMatch = event.key.toLowerCase() === this.key().toLowerCase();
+        const ctrlMatch = this.ctrl() ? event.ctrlKey || event.metaKey : !event.ctrlKey && !event.metaKey;
+        const shiftMatch = this.shift() ? event.shiftKey : !event.shiftKey;
+        const altMatch = this.alt() ? event.altKey : !event.altKey;
+
+        if (keyMatch && ctrlMatch && shiftMatch && altMatch) {
+            event.preventDefault();
+            this.triggered.emit(event);
+        }
+    }
+}
+
+// Usage: <button appShortcut="s" ctrl (triggered)="save()">Save (Ctrl+S)</button>
+```
+
+## Structural Directives
+
+Use structural directives for DOM manipulation beyond control flow (portals, overlays, dynamic insertion points). For conditionals and loops, use native `@if`, `@for`, `@switch`.
+
+### Portal Directive
+
+Render content in a different DOM location:
+
+```typescript
+import { Directive, inject, TemplateRef, ViewContainerRef, OnInit, OnDestroy, input } from '@angular/core';
+
+@Directive({
+    selector: '[appPortal]',
+})
+export class Portal implements OnInit, OnDestroy {
+    private templateRef = inject(TemplateRef<any>);
+    private viewContainerRef = inject(ViewContainerRef);
+    private viewRef: EmbeddedViewRef<any> | null = null;
+
+    // Target container selector or element
+    target = input<string | HTMLElement>('body', { alias: 'appPortal' });
+
+    ngOnInit() {
+        const container = this.getContainer();
+        if (container) {
+            this.viewRef = this.viewContainerRef.createEmbeddedView(this.templateRef);
+            this.viewRef.rootNodes.forEach((node) => container.appendChild(node));
+        }
+    }
+
+    ngOnDestroy() {
+        this.viewRef?.destroy();
+    }
+
+    private getContainer(): HTMLElement | null {
+        const target = this.target();
+        if (typeof target === 'string') {
+            return document.querySelector(target);
+        }
+        return target;
+    }
+}
+
+// Usage: Render modal at body level
+// <div *appPortal="'body'">
+//   <div class="modal">Modal content</div>
+// </div>
+```
+
+### Lazy Render Directive
+
+Defer rendering until condition is met (one-time):
+
+```typescript
+@Directive({
+    selector: '[appLazyRender]',
+})
+export class LazyRender {
+    private templateRef = inject(TemplateRef<any>);
+    private viewContainer = inject(ViewContainerRef);
+    private rendered = false;
+
+    condition = input.required<boolean>({ alias: 'appLazyRender' });
+
+    constructor() {
+        effect(() => {
+            // Only render once when condition becomes true
+            if (this.condition() && !this.rendered) {
+                this.viewContainer.createEmbeddedView(this.templateRef);
+                this.rendered = true;
+            }
+        });
+    }
+}
+
+// Usage: Render heavy component only when tab is first activated
+// <div *appLazyRender="activeTab() === 'reports'">
+//   <app-heavy-reports />
+// </div>
+```
+
+### Template Outlet with Context
+
+```typescript
+interface TemplateContext<T> {
+    $implicit: T;
+    item: T;
+    index: number;
+}
+
+@Directive({
+    selector: '[appTemplateOutlet]',
+})
+export class TemplateOutlet<T> {
+    private viewContainer = inject(ViewContainerRef);
+    private currentView: EmbeddedViewRef<TemplateContext<T>> | null = null;
+
+    template = input.required<TemplateRef<TemplateContext<T>>>({
+        alias: 'appTemplateOutlet',
+    });
+    context = input.required<T>({ alias: 'appTemplateOutletContext' });
+    index = input(0, { alias: 'appTemplateOutletIndex' });
+
+    constructor() {
+        effect(() => {
+            const template = this.template();
+            const context = this.context();
+            const index = this.index();
+
+            if (this.currentView) {
+                this.currentView.context.$implicit = context;
+                this.currentView.context.item = context;
+                this.currentView.context.index = index;
+                this.currentView.markForCheck();
+            } else {
+                this.currentView = this.viewContainer.createEmbeddedView(template, {
+                    $implicit: context,
+                    item: context,
+                    index,
+                });
+            }
+        });
+    }
+}
+
+// Usage: Custom list with template
+// <ng-template #itemTemplate let-item let-i="index">
+//   <div>{{ i }}: {{ item.name }}</div>
+// </ng-template>
+// <ng-container
+//   *appTemplateOutlet="itemTemplate; context: item; index: i"
+// />
+```
+
+## Host Directives
+
+Compose directives on components or other directives:
+
+```typescript
+// Reusable behavior directives
+@Directive({
+    selector: '[focusable]',
+    host: {
+        'tabindex': '0',
+        '(focus)': 'onFocus()',
+        '(blur)': 'onBlur()',
+        '[class.focused]': 'isFocused()',
+    },
+})
+export class Focusable {
+    isFocused = signal(false);
+
+    onFocus() {
+        this.isFocused.set(true);
+    }
+    onBlur() {
+        this.isFocused.set(false);
+    }
+}
+
+@Directive({
+    selector: '[disableable]',
+    host: {
+        '[class.disabled]': 'disabled()',
+        '[attr.aria-disabled]': 'disabled()',
+    },
+})
+export class Disableable {
+    disabled = input(false, { transform: booleanAttribute });
+}
+
+// Component using host directives
+@Component({
+    selector: 'app-custom-button',
+    hostDirectives: [
+        Focusable,
+        {
+            directive: Disableable,
+            inputs: ['disabled'],
+        },
+    ],
+    host: {
+        'role': 'button',
+        '(click)': 'onClick($event)',
+        '(keydown.enter)': 'onClick($event)',
+        '(keydown.space)': 'onClick($event)',
+    },
+    template: `<ng-content />`,
+})
+export class CustomButton {
+    private disableable = inject(Disableable);
+
+    clicked = output<void>();
+
+    onClick(event: Event) {
+        if (!this.disableable.disabled()) {
+            this.clicked.emit();
+        }
+    }
+}
+
+// Usage: <app-custom-button disabled>Click me</app-custom-button>
+```
+
+### Exposing Host Directive Outputs
+
+```typescript
+@Directive({
+    selector: '[hoverable]',
+    host: {
+        '(mouseenter)': 'onEnter()',
+        '(mouseleave)': 'onLeave()',
+        '[class.hovered]': 'isHovered()',
+    },
+})
+export class Hoverable {
+    isHovered = signal(false);
+
+    hoverChange = output<boolean>();
+
+    onEnter() {
+        this.isHovered.set(true);
+        this.hoverChange.emit(true);
+    }
+
+    onLeave() {
+        this.isHovered.set(false);
+        this.hoverChange.emit(false);
+    }
+}
+
+@Component({
+    selector: 'app-card',
+    hostDirectives: [
+        {
+            directive: Hoverable,
+            outputs: ['hoverChange'],
+        },
+    ],
+    template: `<ng-content />`,
+})
+export class Card {}
+
+// Usage: <app-card (hoverChange)="onHover($event)">...</app-card>
+```
+
+## Directive Composition API
+
+Combine multiple behaviors:
+
+```typescript
+// Base directives
+@Directive({ selector: '[withRipple]' })
+export class Ripple {
+    // Ripple effect implementation
+}
+
+@Directive({ selector: '[withElevation]' })
+export class Elevation {
+    elevation = input(2);
+}
+
+// Composed component
+@Component({
+    selector: 'app-material-button',
+    hostDirectives: [
+        Ripple,
+        {
+            directive: Elevation,
+            inputs: ['elevation'],
+        },
+        {
+            directive: Disableable,
+            inputs: ['disabled'],
+        },
+    ],
+    template: `<ng-content />`,
+})
+export class MaterialButton {}
+```

+
+### Auto-Focus Directive
+
+```typescript

+    selector: '[appAutoFocus]',
+})
+export class AutoFocus {
+    private el = inject(ElementRef<HTMLElement>);
+
+    enabled = input(true, { alias: 'appAutoFocus', transform: booleanAttribute });
+    delay = input(0);
+
+    constructor() {
+        afterNextRender(() => {
+            if (this.enabled()) {
+                setTimeout(() => {
+                    this.el.nativeElement.focus();
+                }, this.delay());
+            }
+        });
+    }
+}
+
+// Usage: <input appAutoFocus />
+// Usage: <input [appAutoFocus]="shouldFocus()" [delay]="100" />
+```
+
+### Text Selection Directive
+
+```typescript
+@Directive({
+    selector: '[appSelectAll]',
+    host: {
+        '(focus)': 'onFocus()',
+        '(click)': 'onClick($event)',
+    },
+})
+export class SelectAll {
+    private el = inject(ElementRef<HTMLInputElement>);
+
+    onFocus() {
+        // Delay to ensure value is set
+        setTimeout(() => this.el.nativeElement.select(), 0);
+    }
+
+    onClick(event: MouseEvent) {
+        // Select all on first click if not already focused
+        if (document.activeElement !== this.el.nativeElement) {
+            this.el.nativeElement.select();
+        }
+    }
+}
+
+// Usage: <input appSelectAll value="Select me on focus" />
+```
+
+### Copy to Clipboard
+
+```typescript

+    selector: '[appCopyToClipboard]',
+    host: {
+        '(click)': 'copy()',
+        '[style.cursor]': '"pointer"',
+    },
+})
+export class CopyToClipboard {
+    text = input.required<string>({ alias: 'appCopyToClipboard' });
+
+    copied = output<void>();
+    error = output<Error>();
+
+    async copy() {
+        try {
+            await navigator.clipboard.writeText(this.text());
+            this.copied.emit();
+        } catch (err) {
+            this.error.emit(err as Error);
+        }
+    }
+}
+
+// Usage:
+// <button [appCopyToClipboard]="textToCopy" (copied)="showToast('Copied!')">
+//   Copy
+// </button>
+```
+
+## Form Directives
+
+### Trim Input
+
+```typescript
+@Directive({
+    selector: 'input[appTrim], textarea[appTrim]',
+    host: {
+        '(blur)': 'onBlur()',
+    },
+})
+export class Trim {
+    private el = inject(ElementRef<HTMLInputElement | HTMLTextAreaElement>);
+    private ngControl = inject(NgControl, { optional: true, self: true });
+
+    onBlur() {
+        const value = this.el.nativeElement.value;
+        const trimmed = value.trim();
+
+        if (value !== trimmed) {

+            this.ngControl?.control?.setValue(trimmed);
+        }
+    }
+}
+
+// Usage: <input appTrim formControlName="name" />
+```
+
+### Input Mask
+
+```typescript
+@Directive({
+    selector: '[appMask]',
+    host: {
+        '(input)': 'onInput($event)',
+        '(keydown)': 'onKeydown($event)',

+description: Build signal-based forms in Angular v21+ using the new Signal Forms API. Use for form creation with automatic two-way binding, schema-based validation, field state management, and dynamic forms. Triggers on form implementation, adding validation, creating multi-step forms, or building forms with conditional fields. Signal Forms are experimental but recommended for new Angular projects. Don't use for template-driven forms without signals or third-party form libraries like Formly or ngx-formly.

+
+# Angular Signal Forms
+
+Build type-safe, reactive forms using Angular's Signal Forms API. Signal Forms provide automatic two-way binding, schema-based validation, and reactive field state.
+
+**Note:** Signal Forms are experimental in Angular v21. For production apps requiring stability, see [references/form-patterns.md](references/form-patterns.md) for Reactive Forms patterns.
+
+## Basic Setup
+
+```typescript
+import { Component, signal } from '@angular/core';
+import { form, FormField, required, email } from '@angular/forms/signals';
+
+interface LoginData {
+    email: string;
+    password: string;
+}
+
+@Component({
+    selector: 'app-login',
+    imports: [FormField],
+    template: `
+        <form (submit)="onSubmit($event)">
+            <label>
+                Email
+                <input
+                    type="email"
+                    [formField]="loginForm.email" />
+            </label>
+            @if (loginForm.email().touched() && loginForm.email().invalid()) {
+                <p class="error">{{ loginForm.email().errors()[0].message }}</p>
+            }
+
+            <label>
+                Password
+                <input
+                    type="password"
+                    [formField]="loginForm.password" />
+            </label>
+            @if (loginForm.password().touched() && loginForm.password().invalid()) {
+                <p class="error">{{ loginForm.password().errors()[0].message }}</p>
+            }
+
+            <button
+                type="submit"
+                [disabled]="loginForm().invalid()">
+                Login
+            </button>
+        </form>
+    `,
+})
+export class Login {
+    // Form model - a writable signal
+    loginModel = signal<LoginData>({
+        email: '',
+        password: '',
+    });
+
+    // Create form with validation schema
+    loginForm = form(this.loginModel, (schemaPath) => {
+        required(schemaPath.email, { message: 'Email is required' });
+        email(schemaPath.email, { message: 'Enter a valid email address' });
+        required(schemaPath.password, { message: 'Password is required' });
+    });
+
+    onSubmit(event: Event) {
+        event.preventDefault();
+        if (this.loginForm().valid()) {
+            const credentials = this.loginModel();
+            console.log('Submitting:', credentials);
+        }
+    }
+}
+```
+
+## Form Models
+
+Form models are writable signals that serve as the single source of truth:
+
+```typescript
+// Define interface for type safety
+interface UserProfile {
+    name: string;
+    email: string;
+    age: number | null;
+    preferences: {
+        newsletter: boolean;
+        theme: 'light' | 'dark';
+    };
+}
+
+// Create model signal with initial values
+const userModel = signal<UserProfile>({
+    name: '',
+    email: '',
+    age: null,
+    preferences: {
+        newsletter: false,
+        theme: 'light',
+    },
+});
+
+// Create form from model
+const userForm = form(userModel);
+
+// Access nested fields via dot notation
+userForm.name; // FieldTree<string>
+userForm.preferences.theme; // FieldTree<'light' | 'dark'>
+```
+
+### Reading Values
+
+```typescript
+// Read entire model
+const data = this.userModel();
+
+// Read field value via field state
+const name = this.userForm.name().value();
+const theme = this.userForm.preferences.theme().value();
+```
+
+### Updating Values
+
+```typescript
+// Replace entire model
+this.userModel.set({
+    name: 'Alice',
+    email: 'alice@example.com',
+    age: 30,
+    preferences: { newsletter: true, theme: 'dark' },
+});
+
+// Update single field
+this.userForm.name().value.set('Bob');
+this.userForm.age().value.update((age) => (age ?? 0) + 1);
+```
+
+## Field State
+
+Each field provides reactive signals for validation, interaction, and availability:
+
+```typescript
+const emailField = this.form.email();
+
+// Validation state
+emailField.valid(); // true if passes all validation
+emailField.invalid(); // true if has validation errors
+emailField.errors(); // array of error objects
+emailField.pending(); // true if async validation in progress
+
+// Interaction state
+emailField.touched(); // true after focus + blur
+emailField.dirty(); // true after user modification
+
+// Availability state
+emailField.disabled(); // true if field is disabled
+emailField.hidden(); // true if field should be hidden
+emailField.readonly(); // true if field is readonly
+
+// Value
+emailField.value(); // current field value (signal)
+```
+
+### Form-Level State
+
+The form itself is also a field with aggregated state:
+
+```typescript
+// Form is valid when all interactive fields are valid
+this.form().valid();
+
+// Form is touched when any field is touched
+this.form().touched();
+
+// Form is dirty when any field is modified
+this.form().dirty();
+```
+
+## Validation
+
+### Built-in Validators
+
+```typescript
+import { form, required, email, min, max, minLength, maxLength, pattern } from '@angular/forms/signals';
+
+const userForm = form(this.userModel, (schemaPath) => {
+    // Required field
+    required(schemaPath.name, { message: 'Name is required' });
+
+    // Email format
+    email(schemaPath.email, { message: 'Invalid email' });
+
+    // Numeric range
+    min(schemaPath.age, 18, { message: 'Must be 18+' });
+    max(schemaPath.age, 120, { message: 'Invalid age' });
+
+    // String/array length
+    minLength(schemaPath.password, 8, { message: 'Min 8 characters' });
+    maxLength(schemaPath.bio, 500, { message: 'Max 500 characters' });
+
+    // Regex pattern
+    pattern(schemaPath.phone, /^\d{3}-\d{3}-\d{4}$/, {
+        message: 'Format: 555-123-4567',
+    });
+});
+```
+
+### Conditional Validation
+
+```typescript
+const orderForm = form(this.orderModel, (schemaPath) => {
+    required(schemaPath.promoCode, {
+        message: 'Promo code required for discounts',
+        when: ({ valueOf }) => valueOf(schemaPath.applyDiscount),
+    });
+});
+```
+
+### Custom Validators
+
+```typescript
+import { validate } from '@angular/forms/signals';
+
+const signupForm = form(this.signupModel, (schemaPath) => {
+    // Custom validation logic
+    validate(schemaPath.username, ({ value }) => {
+        if (value().includes(' ')) {
+            return { kind: 'noSpaces', message: 'Username cannot contain spaces' };
+        }
+        return null;
+    });
+});
+```
+
+### Cross-Field Validation
+
+```typescript
+const passwordForm = form(this.passwordModel, (schemaPath) => {
+    required(schemaPath.password);
+    required(schemaPath.confirmPassword);
+
+    // Compare fields
+    validate(schemaPath.confirmPassword, ({ value, valueOf }) => {
+        if (value() !== valueOf(schemaPath.password)) {
+            return { kind: 'mismatch', message: 'Passwords do not match' };
+        }
+        return null;
+    });
+});
+```
+
+### Async Validation
+
+```typescript
+import { validateHttp } from '@angular/forms/signals';
+
+const signupForm = form(this.signupModel, (schemaPath) => {
+    validateHttp(schemaPath.username, {
+        request: ({ value }) => `/api/check-username?u=${value()}`,
+        onSuccess: (response: { taken: boolean }) => {
+            if (response.taken) {
+                return { kind: 'taken', message: 'Username already taken' };
+            }
+            return null;
+        },
+        onError: () => ({
+            kind: 'networkError',
+            message: 'Could not verify username',
+        }),
+    });
+});
+```
+
+## Conditional Fields
+
+### Hidden Fields
+
+```typescript
+import { hidden } from '@angular/forms/signals';
+
+const profileForm = form(this.profileModel, (schemaPath) => {
+    hidden(schemaPath.publicUrl, ({ valueOf }) => !valueOf(schemaPath.isPublic));
+});
+```
+
+```html
+@if (!profileForm.publicUrl().hidden()) {
+<input [formField]="profileForm.publicUrl" />
+}
+```
+
+### Disabled Fields
+
+```typescript
+import { disabled } from '@angular/forms/signals';
+
+const orderForm = form(this.orderModel, (schemaPath) => {
+    disabled(schemaPath.couponCode, ({ valueOf }) => valueOf(schemaPath.total) < 50);
+});
+```
+
+### Readonly Fields
+
+```typescript
+import { readonly } from '@angular/forms/signals';
+
+const accountForm = form(this.accountModel, (schemaPath) => {
+    readonly(schemaPath.username); // Always readonly
+});
+```
+
+## Form Submission

+
+## Arrays and Dynamic Fields
+
+```typescript
+interface Order {
+    items: Array<{ product: string; quantity: number }>;
+}
+
+@Component({
+    template: `
+        @for (item of orderForm.items; track $index; let i = $index) {

+        applyEach(schemaPath.items, (item) => {
+            required(item.product, { message: 'Product required' });
+            min(item.quantity, 1, { message: 'Min quantity is 1' });

+            items: m.items.filter((_, i) => i !== index),
+        }));
+    }
+}
+```
+
+## Displaying Errors
+
+```html
+<input [formField]="form.email" />
+
+@if (form.email().touched() && form.email().invalid()) {
+<ul class="errors">
+    @for (error of form.email().errors(); track error) {
+    <li>{{ error.message }}</li>
+    }
+</ul>
+} @if (form.email().pending()) {
+<span>Validating...</span>
+}
+```
+
+## Styling Based on State
+
+```html
+<input
+    [formField]="form.email"
+    [class.is-invalid]="form.email().touched() && form.email().invalid()"
+    [class.is-valid]="form.email().touched() && form.email().valid()" />
+```
+
+## Reset Form
+
+```typescript
+async onSubmit() {
+  if (!this.form().valid()) return;
+
+  await this.api.submit(this.model());
+
+  // Clear interaction state
+  this.form().reset();
+
+  // Clear values
+  this.model.set({ email: '', password: '' });
+}

+
+## Reactive Forms (Production-Stable)
+
+For production applications requiring stability guarantees, use Reactive Forms:
+
+```typescript
+import { Component, inject } from '@angular/core';
+import { ReactiveFormsModule, FormBuilder, Validators } from '@angular/forms';
+
+@Component({
+    selector: 'app-login',
+    imports: [ReactiveFormsModule],
+    template: `
+        <form
+            [formGroup]="form"
+            (ngSubmit)="onSubmit()">
+            <input formControlName="email" />
+            @if (form.controls.email.errors?.['required'] && form.controls.email.touched) {
+                <span class="error">Email is required</span>
+            }
+
+            <input
+                type="password"
+                formControlName="password" />
+
+            <button
+                type="submit"
+                [disabled]="form.invalid">
+                Login
+            </button>
+        </form>
+    `,
+})
+export class Login {
+    private fb = inject(FormBuilder);
+
+    form = this.fb.group({
+        email: ['', [Validators.required, Validators.email]],
+        password: ['', [Validators.required, Validators.minLength(8)]],
+    });
+
+    onSubmit() {
+        if (this.form.valid) {
+            console.log(this.form.value);
+        }
+    }
+}
+```
+
+## Typed Reactive Forms
+
+### Typed FormControl
+
+```typescript
+import { FormControl } from '@angular/forms';
+
+// Inferred type: FormControl<string | null>
+const name = new FormControl('');
+
+// Non-nullable (no reset to null)
+const email = new FormControl('', { nonNullable: true });
+// Type: FormControl<string>
+
+// With validators
+const username = new FormControl('', {
+    nonNullable: true,
+    validators: [Validators.required, Validators.minLength(3)],
+});
+```
+
+### Typed FormGroup
+
+```typescript
+import { FormGroup, FormControl } from '@angular/forms';
+
+interface UserForm {
+    name: FormControl<string>;
+    email: FormControl<string>;
+    age: FormControl<number | null>;
+}
+
+const form = new FormGroup<UserForm>({
+    name: new FormControl('', { nonNullable: true }),
+    email: new FormControl('', { nonNullable: true }),
+    age: new FormControl<number | null>(null),
+});
+
+// Typed value access
+const name: string = form.controls.name.value;
+```
+
+### NonNullableFormBuilder
+
+```typescript
+import { inject } from '@angular/core';
+import { NonNullableFormBuilder } from '@angular/forms';
+
+@Component({...})
+export class Profile {
+  private fb = inject(NonNullableFormBuilder);
+
+  form = this.fb.group({
+    name: ['', Validators.required],           // FormControl<string>
+    email: ['', [Validators.required, Validators.email]],
+    preferences: this.fb.group({
+      newsletter: [false],                      // FormControl<boolean>
+      theme: ['light' as 'light' | 'dark'],    // FormControl<'light' | 'dark'>
+    }),
+  });
+}
+```
+
+## FormBuilder Patterns
+
+### Nested FormGroups
+
+```typescript
+@Component({
+    imports: [ReactiveFormsModule],
+    template: `
+        <form
+            [formGroup]="form"
+            (ngSubmit)="onSubmit()">
+            <input
+                formControlName="name"
+                placeholder="Name" />
+
+            <div formGroupName="address">
+                <input
+                    formControlName="street"
+                    placeholder="Street" />
+                <input
+                    formControlName="city"
+                    placeholder="City" />
+                <input
+                    formControlName="zip"
+                    placeholder="ZIP" />
+            </div>
+
+            <button type="submit">Submit</button>
+        </form>
+    `,
+})
+export class Profile {
+    private fb = inject(NonNullableFormBuilder);
+
+    form = this.fb.group({
+        name: ['', Validators.required],
+        address: this.fb.group({
+            street: [''],
+            city: ['', Validators.required],
+            zip: ['', [Validators.required, Validators.pattern(/^\d{5}$/)]],
+        }),
+    });
+}
+```
+
+## Dynamic Forms with FormArray
+
+```typescript
+import { FormArray } from '@angular/forms';
+
+@Component({
+    imports: [ReactiveFormsModule],
+    template: `
+        <form [formGroup]="form">
+            <div formArrayName="items">
+                @for (item of items.controls; track $index; let i = $index) {
+                    <div [formGroupName]="i">
+                        <input
+                            formControlName="product"
+                            placeholder="Product" />
+                        <input
+                            formControlName="quantity"
+                            type="number" />
+                        <button
+                            type="button"
+                            (click)="removeItem(i)">
+                            Remove
+                        </button>
+                    </div>
+                }
+            </div>
+            <button
+                type="button"
+                (click)="addItem()">
+                Add Item
+            </button>
+        </form>
+    `,
+})
+export class Order {
+    private fb = inject(NonNullableFormBuilder);
+
+    form = this.fb.group({
+        items: this.fb.array([this.createItem()]),
+    });
+
+    get items() {
+        return this.form.controls.items;
+    }
+
+    createItem() {
+        return this.fb.group({
+            product: ['', Validators.required],
+            quantity: [1, [Validators.required, Validators.min(1)]],
+        });
+    }
+
+    addItem() {
+        this.items.push(this.createItem());
+    }
+
+    removeItem(index: number) {
+        this.items.removeAt(index);
+    }
+}
+```
+
+## Custom Validators
+
+### Sync Validator
+
+```typescript
+import { AbstractControl, ValidationErrors, ValidatorFn } from '@angular/forms';
+
+export function forbiddenValue(forbidden: string): ValidatorFn {
+  return (control: AbstractControl): ValidationErrors | null => {
+    return control.value === forbidden
+      ? { forbiddenValue: { value: control.value } }
+      : null;
+  };
+}
+
+// Usage
+name: ['', [Validators.required, forbiddenValue('admin')]],
+```
+
+### Cross-Field Validator
+
+```typescript
+export function passwordMatch(): ValidatorFn {
+    return (group: AbstractControl): ValidationErrors | null => {
+        const password = group.get('password')?.value;
+        const confirm = group.get('confirmPassword')?.value;
+        return password === confirm ? null : { passwordMismatch: true };
+    };
+}
+
+// Usage
+form = this.fb.group(
+    {
+        password: ['', [Validators.required, Validators.minLength(8)]],
+        confirmPassword: ['', Validators.required],
+    },
+    { validators: passwordMatch() },
+);
+```
+
+### Async Validator
+
+```typescript
+import { AsyncValidatorFn } from '@angular/forms';
+import { map, catchError, of } from 'rxjs';
+
+export function uniqueEmail(userService: User): AsyncValidatorFn {
+  return (control: AbstractControl) => {
+    return userService.checkEmail(control.value).pipe(
+      map(exists => exists ? { emailTaken: true } : null),
+      catchError(() => of(null))
+    );
+  };
+}
+
+// Usage
+email: ['',
+  [Validators.required, Validators.email],  // sync validators
+  [uniqueEmail(this.userService)]            // async validators
+],
+```
+
+## Form State Management
+
+### State Properties
+
+```typescript
+// Check states
+form.valid; // All validations pass
+form.invalid; // Has validation errors
+form.pending; // Async validation in progress
+form.dirty; // Value changed by user
+form.pristine; // Value not changed
+form.touched; // Control has been focused
+form.untouched; // Control never focused
+
+// Update values
+form.setValue({ name: 'John', email: 'john@example.com' }); // Must include all
+form.patchValue({ name: 'John' }); // Partial update
+
+// Reset
+form.reset();
+form.reset({ name: 'Default' });
+
+// Disable/Enable
+form.disable();
+form.enable();
+form.controls.email.disable();
+
+// Mark states
+form.markAllAsTouched(); // Show all errors
+form.markAsPristine();
+form.markAsDirty();
+```
+
+### Value Changes Observable
+
+```typescript
+// Subscribe to value changes
+form.valueChanges.subscribe((value) => {
+    console.log('Form value:', value);
+});
+
+// Single control with debounce
+form.controls.email.valueChanges.pipe(debounceTime(300), distinctUntilChanged()).subscribe((email) => {
+    this.validateEmail(email);
+});
+
+// Status changes
+form.statusChanges.subscribe((status) => {
+    console.log('Form status:', status); // VALID, INVALID, PENDING
+});
+```
+
+### Unified Events (Angular v18+)
+
+```typescript
+import {
+    ValueChangeEvent,
+    StatusChangeEvent,
+    PristineChangeEvent,
+    TouchedChangeEvent,
+    FormSubmittedEvent,
+    FormResetEvent,
+} from '@angular/forms';
+
+form.events.subscribe((event) => {
+    if (event instanceof ValueChangeEvent) {
+        console.log('Value changed:', event.value);
+    }
+    if (event instanceof StatusChangeEvent) {
+        console.log('Status changed:', event.status);
+    }
+    if (event instanceof PristineChangeEvent) {
+        console.log('Pristine changed:', event.pristine);
+    }
+    if (event instanceof TouchedChangeEvent) {
+        console.log('Touched changed:', event.touched);
+    }
+    if (event instanceof FormSubmittedEvent) {
+        console.log('Form submitted');
+    }
+    if (event instanceof FormResetEvent) {
+        console.log('Form reset');
+    }
+});
+```
+
+## Error Display Pattern
+
+```typescript
+@Component({
+    template: `
+        <input formControlName="email" />
+
+        @if (form.controls.email.invalid && form.controls.email.touched) {
+            <div class="errors">
+                @if (form.controls.email.errors?.['required']) {
+                    <span>Email is required</span>
+                }
+                @if (form.controls.email.errors?.['email']) {
+                    <span>Invalid email format</span>
+                }
+            </div>
+        }
+    `,
+})
+export class Form {
+    // Helper for cleaner templates
+    hasError(controlName: string, errorKey: string): boolean {
+        const control = this.form.get(controlName);
+        return (control?.hasError(errorKey) && control?.touched) || false;
+    }
+}
+```
+
+## Form Submission Pattern
+
+```typescript
+@Component({
+    template: `
+        <form
+            [formGroup]="form"
+            (ngSubmit)="onSubmit()">
+            <!-- fields -->
+            <button
+                type="submit"
+                [disabled]="form.invalid || isSubmitting">
+                {{ isSubmitting ? 'Submitting...' : 'Submit' }}
+            </button>
+        </form>
+    `,
+})
+export class Form {
+    isSubmitting = false;
+
+    async onSubmit() {
+        if (this.form.invalid) {
+            this.form.markAllAsTouched();
+            return;
+        }
+
+        this.isSubmitting = true;
+        try {
+            await this.api.submit(this.form.getRawValue());
+            this.form.reset();
+        } catch (error) {
+            // Handle error
+        } finally {
+            this.isSubmitting = false;
+        }
+    }

+description: Implement HTTP data fetching in Angular v20+ using resource(), httpResource(), and HttpClient. Use for API calls, data loading with signals, request/response handling, and interceptors. Triggers on data fetching, API integration, loading states, error handling, or converting Observable-based HTTP to signal-based patterns.
+---
+
+# Angular HTTP & Data Fetching
+
+Fetch data in Angular using signal-based `resource()`, `httpResource()`, and the traditional `HttpClient`.
+
+## httpResource() - Signal-Based HTTP
+
+`httpResource()` wraps HttpClient with signal-based state management:
+
+```typescript
+import { Component, signal } from '@angular/core';
+import { httpResource } from '@angular/common/http';
+
+interface User {
+    id: number;
+    name: string;
+    email: string;
+}
+
+@Component({
+    selector: 'app-user-profile',
+    template: `
+        @if (userResource.isLoading()) {
+            <p>Loading...</p>
+        } @else if (userResource.error()) {
+            <p>Error: {{ userResource.error()?.message }}</p>
+            <button (click)="userResource.reload()">Retry</button>
+        } @else if (userResource.hasValue()) {
+            <h1>{{ userResource.value().name }}</h1>
+            <p>{{ userResource.value().email }}</p>
+        }
+    `,
+})
+export class UserProfile {
+    userId = signal('123');
+
+    // Reactive HTTP resource - refetches when userId changes
+    userResource = httpResource<User>(() => `/api/users/${this.userId()}`);
+}
+```
+
+### httpResource Options
+
+```typescript
+// Simple GET request
+userResource = httpResource<User>(() => `/api/users/${this.userId()}`);
+
+// With full request options
+userResource = httpResource<User>(() => ({
+    url: `/api/users/${this.userId()}`,
+    method: 'GET',
+    headers: { Authorization: `Bearer ${this.token()}` },
+    params: { include: 'profile' },
+}));
+
+// With default value
+usersResource = httpResource<User[]>(() => '/api/users', {
+    defaultValue: [],
+});
+
+// Skip request when params undefined
+userResource = httpResource<User>(() => {
+    const id = this.userId();
+    return id ? `/api/users/${id}` : undefined;
+});
+```
+
+### Resource State
+
+```typescript
+// Status signals
+userResource.value(); // Current value or undefined
+userResource.hasValue(); // Boolean - has resolved value
+userResource.error(); // Error or undefined
+userResource.isLoading(); // Boolean - currently loading
+userResource.status(); // 'idle' | 'loading' | 'reloading' | 'resolved' | 'error' | 'local'
+
+// Actions
+userResource.reload(); // Manually trigger reload
+userResource.set(value); // Set local value
+userResource.update(fn); // Update local value
+```
+
+## resource() - Generic Async Data
+
+For non-HTTP async operations or custom fetch logic:
+
+```typescript
+import { resource, signal } from '@angular/core';
+
+@Component({...})
+export class Search {
+  query = signal('');
+
+  searchResource = resource({
+    // Reactive params - triggers reload when changed
+    params: () => ({ q: this.query() }),
+
+    // Async loader function
+    loader: async ({ params, abortSignal }) => {
+      if (!params.q) return [];
+
+      const response = await fetch(`/api/search?q=${params.q}`, {
+        signal: abortSignal,
+      });
+      return response.json() as Promise<SearchResult[]>;
+    },
+  });
+}
+```
+
+### Resource with Default Value
+
+```typescript
+todosResource = resource({
+    defaultValue: [] as Todo[],
+    params: () => ({ filter: this.filter() }),
+    loader: async ({ params }) => {
+        const res = await fetch(`/api/todos?filter=${params.filter}`);
+        return res.json();
+    },
+});
+
+// value() returns Todo[] (never undefined)
+```
+
+### Conditional Loading
+
+```typescript
+const userId = signal<string | null>(null);
+
+userResource = resource({
+    params: () => {
+        const id = userId();
+        // Return undefined to skip loading
+        return id ? { id } : undefined;
+    },
+    loader: async ({ params }) => {
+        return fetch(`/api/users/${params.id}`).then((r) => r.json());
+    },
+});
+// Status is 'idle' when params returns undefined
+```
+
+## HttpClient - Traditional Approach
+
+For complex scenarios or when you need Observable operators:
+
+```typescript
+import { Component, inject } from '@angular/core';
+import { HttpClient } from '@angular/common/http';
+import { toSignal } from '@angular/core/rxjs-interop';
+
+@Component({...})
+export class Users {
+  private http = inject(HttpClient);
+
+  // Convert Observable to Signal
+  users = toSignal(
+    this.http.get<User[]>('/api/users'),
+    { initialValue: [] }
+  );
+
+  // Or use Observable directly
+  users$ = this.http.get<User[]>('/api/users');
+}
+```
+
+### HTTP Methods
+
+```typescript
+private http = inject(HttpClient);
+
+// GET
+getUser(id: string) {
+  return this.http.get<User>(`/api/users/${id}`);
+}
+
+// POST
+createUser(user: CreateUserDto) {
+  return this.http.post<User>('/api/users', user);
+}
+
+// PUT
+updateUser(id: string, user: UpdateUserDto) {
+  return this.http.put<User>(`/api/users/${id}`, user);
+}
+
+// PATCH
+patchUser(id: string, changes: Partial<User>) {
+  return this.http.patch<User>(`/api/users/${id}`, changes);
+}
+
+// DELETE
+deleteUser(id: string) {
+  return this.http.delete<void>(`/api/users/${id}`);
+}
+```
+
+### Request Options
+
+```typescript
+this.http.get<User[]>('/api/users', {
+    headers: {
+        'Authorization': 'Bearer token',
+        'Content-Type': 'application/json',
+    },
+    params: {
+        page: '1',
+        limit: '10',
+        sort: 'name',
+    },
+    observe: 'response', // Get full HttpResponse
+    responseType: 'json',
+});
+```
+
+## Interceptors
+
+### Functional Interceptor (Recommended)
+
+```typescript
+// auth.interceptor.ts
+import { HttpInterceptorFn } from '@angular/common/http';
+import { inject } from '@angular/core';
+
+export const authInterceptor: HttpInterceptorFn = (req, next) => {
+    const authService = inject(Auth);
+    const token = authService.token();
+
+    if (token) {
+        req = req.clone({
+            setHeaders: { Authorization: `Bearer ${token}` },
+        });
+    }
+
+    return next(req);
+};
+
+// error.interceptor.ts
+export const errorInterceptor: HttpInterceptorFn = (req, next) => {
+    return next(req).pipe(
+        catchError((error: HttpErrorResponse) => {
+            if (error.status === 401) {
+                inject(Router).navigate(['/login']);
+            }
+            return throwError(() => error);
+        }),
+    );
+};
+
+// logging.interceptor.ts
+export const loggingInterceptor: HttpInterceptorFn = (req, next) => {
+    const started = Date.now();
+    return next(req).pipe(
+        tap({
+            next: () => console.log(`${req.method} ${req.url} - ${Date.now() - started}ms`),
+            error: (err) => console.error(`${req.method} ${req.url} failed`, err),
+        }),
+    );
+};
+```
+
+### Register Interceptors
+
+```typescript
+// app.config.ts
+import { provideHttpClient, withInterceptors } from '@angular/common/http';
+
+export const appConfig: ApplicationConfig = {
+    providers: [provideHttpClient(withInterceptors([authInterceptor, errorInterceptor, loggingInterceptor]))],
+};
+```
+
+## Error Handling
+
+### With httpResource
+
+```typescript
+@Component({
+    template: `
+        @if (userResource.error(); as error) {
+            <div class="error">
+                <p>{{ getErrorMessage(error) }}</p>
+                <button (click)="userResource.reload()">Retry</button>
+            </div>
+        }
+    `,
+})
+export class UserCmpt {
+    userResource = httpResource<User>(() => `/api/users/${this.userId()}`);
+
+    getErrorMessage(error: unknown): string {
+        if (error instanceof HttpErrorResponse) {
+            return error.error?.message || `Error ${error.status}: ${error.statusText}`;
+        }
+        return 'An unexpected error occurred';
+    }
+}
+```
+
+### With HttpClient
+
+```typescript
+import { catchError, retry } from 'rxjs';
+
+getUser(id: string) {
+  return this.http.get<User>(`/api/users/${id}`).pipe(
+    retry(2), // Retry up to 2 times
+    catchError((error: HttpErrorResponse) => {
+      console.error('Error fetching user:', error);
+      return throwError(() => new Error('Failed to load user'));
+    })
+  );
+}
+```
+
+## Loading States Pattern
+
+```typescript
+@Component({
+    template: `
+        @switch (dataResource.status()) {
+            @case ('idle') {
+                <p>Enter a search term</p>
+            }
+            @case ('loading') {
+                <app-spinner />
+            }
+            @case ('reloading') {
+                <app-data [data]="dataResource.value()" />
+                <app-spinner size="small" />
+            }
+            @case ('resolved') {
+                <app-data [data]="dataResource.value()" />
+            }
+            @case ('error') {
+                <app-error
+                    [error]="dataResource.error()"
+                    (retry)="dataResource.reload()" />
+            }
+        }
+    `,
+})
+export class Data {
+    query = signal('');
+    dataResource = httpResource<Data[]>(() => (this.query() ? `/api/search?q=${this.query()}` : undefined));
+}
+```

+
+## Service Layer Pattern
+
+Encapsulate HTTP logic in services:
+
+```typescript
+import { Injectable, inject, signal, computed } from '@angular/core';
+import { HttpClient } from '@angular/common/http';
+import { httpResource } from '@angular/common/http';
+
+export interface User {
+    id: string;
+    name: string;
+    email: string;
+}
+
+@Injectable({ providedIn: 'root' })
+export class User {
+    private http = inject(HttpClient);
+    private baseUrl = '/api/users';
+
+    // Current user ID for reactive fetching
+    private currentUserId = signal<string | null>(null);
+
+    // Reactive resource that updates when currentUserId changes
+    currentUser = httpResource<User>(() => {
+        const id = this.currentUserId();
+        return id ? `${this.baseUrl}/${id}` : undefined;
+    });
+
+    // Set current user to fetch
+    selectUser(id: string) {
+        this.currentUserId.set(id);
+    }
+
+    // CRUD operations
+    getAll() {
+        return this.http.get<User[]>(this.baseUrl);
+    }
+
+    getById(id: string) {
+        return this.http.get<User>(`${this.baseUrl}/${id}`);
+    }
+
+    create(user: Omit<User, 'id'>) {
+        return this.http.post<User>(this.baseUrl, user);
+    }
+
+    update(id: string, user: Partial<User>) {
+        return this.http.patch<User>(`${this.baseUrl}/${id}`, user);
+    }
+
+    delete(id: string) {
+        return this.http.delete<void>(`${this.baseUrl}/${id}`);
+    }
+}
+```
+
+## Caching Strategies
+
+### Simple In-Memory Cache
+
+```typescript
+@Injectable({ providedIn: 'root' })
+export class CachedUser {
+    private http = inject(HttpClient);
+    private cache = new Map<string, { data: User; timestamp: number }>();
+    private cacheDuration = 5 * 60 * 1000; // 5 minutes
+
+    getUser(id: string): Observable<User> {
+        const cached = this.cache.get(id);
+
+        if (cached && Date.now() - cached.timestamp < this.cacheDuration) {
+            return of(cached.data);
+        }
+
+        return this.http.get<User>(`/api/users/${id}`).pipe(
+            tap((user) => {
+                this.cache.set(id, { data: user, timestamp: Date.now() });
+            }),
+        );
+    }
+
+    invalidateCache(id?: string) {
+        if (id) {
+            this.cache.delete(id);
+        } else {
+            this.cache.clear();
+        }
+    }
+}
+```
+
+### Signal-Based Cache
+
+```typescript
+@Injectable({ providedIn: 'root' })
+export class UserCache {
+    private http = inject(HttpClient);
+
+    // Cache as signal
+    private usersCache = signal<Map<string, User>>(new Map());
+
+    // Computed for easy access
+    users = computed(() => Array.from(this.usersCache().values()));
+
+    getUser(id: string): User | undefined {
+        return this.usersCache().get(id);
+    }
+
+    async fetchUser(id: string): Promise<User> {
+        const cached = this.getUser(id);
+        if (cached) return cached;
+
+        const user = await firstValueFrom(this.http.get<User>(`/api/users/${id}`));
+
+        this.usersCache.update((cache) => {
+            const newCache = new Map(cache);
+            newCache.set(id, user);
+            return newCache;
+        });
+
+        return user;
+    }
+}
+```
+
+## Pagination
+
+### Paginated Resource
+
+```typescript
+interface PaginatedResponse<T> {
+    data: T[];
+    total: number;
+    page: number;
+    pageSize: number;
+    totalPages: number;
+}
+
+@Component({
+    template: `
+        @if (usersResource.isLoading()) {
+            <app-spinner />
+        } @else if (usersResource.hasValue()) {
+            <ul>
+                @for (user of usersResource.value().data; track user.id) {
+                    <li>{{ user.name }}</li>
+                }
+            </ul>
+
+            <div class="pagination">
+                <button
+                    [disabled]="page() === 1"
+                    (click)="prevPage()">
+                    Previous
+                </button>
+
+                <span>Page {{ page() }} of {{ usersResource.value().totalPages }}</span>
+
+                <button
+                    [disabled]="page() >= usersResource.value().totalPages"
+                    (click)="nextPage()">
+                    Next
+                </button>
+            </div>
+        }
+    `,
+})
+export class UsersList {
+    page = signal(1);
+    pageSize = signal(10);
+
+    usersResource = httpResource<PaginatedResponse<User>>(() => ({
+        url: '/api/users',
+        params: {
+            page: this.page().toString(),
+            pageSize: this.pageSize().toString(),
+        },
+    }));
+
+    nextPage() {
+        this.page.update((p) => p + 1);
+    }
+
+    prevPage() {
+        this.page.update((p) => Math.max(1, p - 1));
+    }
+}
+```
+
+### Infinite Scroll
+
+```typescript
+@Component({

+
+        @if (hasMore()) {
+            <button (click)="loadMore()">Load More</button>
+        }
+    `,
+})
+export class InfiniteUsers {
+    private http = inject(HttpClient);
+
+    private page = signal(1);

+
+    allUsers = this.users.asReadonly();
+    isLoading = signal(false);
+    hasMore = computed(() => this.page() < this.totalPages());
+
+    constructor() {
+        this.loadPage(1);
+    }
+
+    loadMore() {
+        this.loadPage(this.page() + 1);
+    }
+
+    private async loadPage(page: number) {
+        this.isLoading.set(true);
+
+        try {
+            const response = await firstValueFrom(
+                this.http.get<PaginatedResponse<User>>('/api/users', {
+                    params: { page: page.toString(), pageSize: '20' },
+                }),

+        }
+    }
+}
+```
+
+## File Upload
+
+### Single File Upload
+
+```typescript
+@Component({
+    template: `
+        <input
+            type="file"
+            (change)="onFileSelected($event)" />

+        if (!file) return;
+
+        const formData = new FormData();
+        formData.append('file', file);
+
+        this.http
+            .post('/api/upload', formData, {
+                reportProgress: true,
+                observe: 'events',
+            })
+            .subscribe((event) => {
+                if (event.type === HttpEventType.UploadProgress && event.total) {

+}
+```
+
+## Request Cancellation
+
+### With resource()
+
+```typescript
+// resource() automatically handles cancellation via abortSignal
+searchResource = resource({

+        });
+        return response.json();
+    },
+});
+```
+
+### With HttpClient
+
+```typescript
+@Component({...})
+export class Search implements OnDestroy {
+  private http = inject(HttpClient);
+  private destroyRef = inject(DestroyRef);
+
+  query = signal('');
+  results = signal<Result[]>([]);
+
+  private searchSubscription?: Subscription;
+
+  search() {
+    // Cancel previous request
+    this.searchSubscription?.unsubscribe();
+
+    this.searchSubscription = this.http
+      .get<Result[]>(`/api/search?q=${this.query()}`)
+      .pipe(takeUntilDestroyed(this.destroyRef))
+      .subscribe(results => this.results.set(results));
+  }
+}
+```
+
+### Debounced Search
+
+```typescript
+@Component({...})
+export class SearchDebounced {
+  query = signal('');
+
+  private http = inject(HttpClient);
+
+  results = toSignal(
+    toObservable(this.query).pipe(
+      debounceTime(300),
+      distinctUntilChanged(),
+      filter(q => q.length >= 2),
+      switchMap(q => this.http.get<Result[]>(`/api/search?q=${q}`)),
+      catchError(() => of([]))
+    ),
+    { initialValue: [] }
+  );
+}
+```

+name: angular-routing
+description: Implement routing in Angular v20+ applications with lazy loading, functional guards, resolvers, and route parameters. Use for navigation setup, protected routes, route-based data loading, and nested routing. Triggers on route configuration, adding authentication guards, implementing lazy loading, or reading route parameters with signals.
+---
+
+# Angular Routing
+
+Configure routing in Angular v20+ with lazy loading, functional guards, and signal-based route parameters.
+
+## Basic Setup
+
+```typescript
+// app.routes.ts
+import { Routes } from '@angular/router';
+
+export const routes: Routes = [
+    { path: '', redirectTo: '/home', pathMatch: 'full' },
+    { path: 'home', component: Home },
+    { path: 'about', component: About },
+    { path: '**', component: NotFound },
+];
+
+// app.config.ts
+import { ApplicationConfig } from '@angular/core';
+import { provideRouter } from '@angular/router';
+import { routes } from './app.routes';
+
+export const appConfig: ApplicationConfig = {
+    providers: [provideRouter(routes)],
+};
+
+// app.component.ts
+import { Component } from '@angular/core';
+import { RouterOutlet, RouterLink, RouterLinkActive } from '@angular/router';
+
+@Component({
+    selector: 'app-root',
+    imports: [RouterOutlet, RouterLink, RouterLinkActive],
+    template: `
+        <nav>
+            <a
+                routerLink="/home"
+                routerLinkActive="active"
+                >Home</a
+            >
+            <a
+                routerLink="/about"
+                routerLinkActive="active"
+                >About</a
+            >
+        </nav>
+        <router-outlet />
+    `,
+})
+export class App {}
+```
+
+## Lazy Loading
+
+Load feature modules on demand:
+
+```typescript
+// app.routes.ts
+export const routes: Routes = [
+    { path: '', redirectTo: '/home', pathMatch: 'full' },
+    { path: 'home', component: Home },
+
+    // Lazy load entire feature
+    {
+        path: 'admin',
+        loadChildren: () => import('./admin/admin.routes').then((m) => m.adminRoutes),
+    },
+
+    // Lazy load single component
+    {
+        path: 'settings',
+        loadComponent: () => import('./settings/settings.component').then((m) => m.Settings),
+    },
+];
+
+// admin/admin.routes.ts
+export const adminRoutes: Routes = [
+    { path: '', component: AdminDashboard },
+    { path: 'users', component: AdminUsers },
+    { path: 'settings', component: AdminSettings },
+];
+```
+
+## Route Parameters
+
+### With Signal Inputs (Recommended)
+
+```typescript
+// Route config
+{ path: 'users/:id', component: UserDetail }
+
+// Component - use input() for route params
+import { Component, input, computed } from '@angular/core';
+
+@Component({
+  selector: 'app-user-detail',
+  template: `
+    <h1>User {{ id() }}</h1>
+  `,
+})
+export class UserDetail {
+  // Route param as signal input
+  id = input.required<string>();
+
+  // Computed based on route param
+  userId = computed(() => parseInt(this.id(), 10));
+}
+```
+
+Enable with `withComponentInputBinding()`:
+
+```typescript
+// app.config.ts
+import { provideRouter, withComponentInputBinding } from '@angular/router';
+
+export const appConfig: ApplicationConfig = {
+    providers: [provideRouter(routes, withComponentInputBinding())],
+};
+```
+
+### Query Parameters
+
+```typescript
+// Route: /search?q=angular&page=1
+
+@Component({...})
+export class Search {
+  // Query params as inputs
+  q = input<string>('');
+  page = input<string>('1');
+
+  currentPage = computed(() => parseInt(this.page(), 10));
+}
+```
+
+### With ActivatedRoute (Alternative)
+
+```typescript
+import { Component, inject } from '@angular/core';
+import { ActivatedRoute } from '@angular/router';
+import { toSignal } from '@angular/core/rxjs-interop';
+import { map } from 'rxjs';
+
+@Component({...})
+export class UserDetail {
+  private route = inject(ActivatedRoute);
+
+  // Convert route params to signal
+  id = toSignal(
+    this.route.paramMap.pipe(map(params => params.get('id'))),
+    { initialValue: null }
+  );
+
+  // Query params
+  query = toSignal(
+    this.route.queryParamMap.pipe(map(params => params.get('q'))),
+    { initialValue: '' }
+  );
+}
+```
+
+## Functional Guards
+
+### Auth Guard
+
+```typescript
+// guards/auth.guard.ts
+import { inject } from '@angular/core';
+import { CanActivateFn, Router } from '@angular/router';
+
+export const authGuard: CanActivateFn = (route, state) => {
+  const authService = inject(Auth);
+  const router = inject(Router);
+
+  if (authService.isAuthenticated()) {
+    return true;
+  }
+
+  // Redirect to login with return URL
+  return router.createUrlTree(['/login'], {
+    queryParams: { returnUrl: state.url },
+  });
+};
+
+// Usage in routes
+{
+  path: 'dashboard',
+  component: Dashboard,
+  canActivate: [authGuard],
+}
+```
+
+### Role Guard
+
+```typescript
+export const roleGuard = (allowedRoles: string[]): CanActivateFn => {
+  return (route, state) => {
+    const authService = inject(Auth);
+    const router = inject(Router);
+
+    const userRole = authService.currentUser()?.role;
+
+    if (userRole && allowedRoles.includes(userRole)) {
+      return true;
+    }
+
+    return router.createUrlTree(['/unauthorized']);
+  };
+};
+
+// Usage
+{
+  path: 'admin',
+  component: Admin,
+  canActivate: [authGuard, roleGuard(['admin', 'superadmin'])],
+}
+```
+
+### Can Deactivate Guard
+
+```typescript
+export interface CanDeactivate {
+  canDeactivate: () => boolean | Promise<boolean>;
+}
+
+export const unsavedChangesGuard: CanDeactivateFn<CanDeactivate> = (component) => {
+  if (component.canDeactivate()) {
+    return true;
+  }
+
+  return confirm('You have unsaved changes. Leave anyway?');
+};
+
+// Component implementation
+@Component({...})
+export class Edit implements CanDeactivate {
+  form = inject(FormBuilder).group({...});
+
+  canDeactivate(): boolean {
+    return !this.form.dirty;
+  }
+}
+
+// Route
+{
+  path: 'edit/:id',
+  component: Edit,
+  canDeactivate: [unsavedChangesGuard],
+}
+```
+
+## Resolvers
+
+Pre-fetch data before route activation:
+
+```typescript
+// resolvers/user.resolver.ts
+import { inject } from '@angular/core';
+import { ResolveFn } from '@angular/router';
+
+export const userResolver: ResolveFn<User> = (route) => {
+  const userService = inject(User);
+  const id = route.paramMap.get('id')!;
+  return userService.getById(id);
+};
+
+// Route config
+{
+  path: 'users/:id',
+  component: UserDetail,
+  resolve: { user: userResolver },
+}
+
+// Component - access resolved data via input
+@Component({...})
+export class UserDetail {
+  user = input.required<User>();
+}
+```
+
+## Nested Routes
+
+```typescript
+// Parent route with children
+export const routes: Routes = [
+    {
+        path: 'products',
+        component: ProductsLayout,
+        children: [
+            { path: '', component: ProductList },
+            { path: ':id', component: ProductDetail },
+            { path: ':id/edit', component: ProductEdit },
+        ],
+    },
+];
+
+// ProductsLayout
+@Component({
+    imports: [RouterOutlet],
+    template: `
+        <h1>Products</h1>
+        <router-outlet />
+        <!-- Child routes render here -->
+    `,
+})
+export class ProductsLayout {}
+```
+
+## Programmatic Navigation
+
+```typescript
+import { Component, inject } from '@angular/core';
+import { Router } from '@angular/router';
+
+@Component({...})
+export class Product {
+  private router = inject(Router);
+
+  // Navigate to route
+  goToProducts() {
+    this.router.navigate(['/products']);
+  }
+
+  // Navigate with params
+  goToProduct(id: string) {
+    this.router.navigate(['/products', id]);
+  }
+
+  // Navigate with query params
+  search(query: string) {
+    this.router.navigate(['/search'], {
+      queryParams: { q: query, page: 1 },
+    });
+  }
+
+  // Navigate relative to current route
+  goToEdit() {
+    this.router.navigate(['edit'], { relativeTo: this.route });
+  }
+
+  // Replace current history entry
+  replaceUrl() {
+    this.router.navigate(['/new-page'], { replaceUrl: true });
+  }
+}
+```
+
+## Route Data
+
+```typescript
+// Static route data
+{
+  path: 'admin',
+  component: Admin,
+  data: {
+    title: 'Admin Dashboard',
+    roles: ['admin'],
+  },
+}
+
+// Access in component
+@Component({...})
+export class AdminCmpt {
+  title = input<string>(); // From route data
+  roles = input<string[]>(); // From route data
+}
+
+// Or via ActivatedRoute
+private route = inject(ActivatedRoute);
+data = toSignal(this.route.data);
+```
+
+## Router Events
+
+```typescript
+import { Router, NavigationStart, NavigationEnd } from '@angular/router';
+import { filter } from 'rxjs';
+
+@Component({...})
+export class AppMain {
+  private router = inject(Router);
+
+  isNavigating = signal(false);
+
+  constructor() {
+    this.router.events.pipe(
+      filter(e => e instanceof NavigationStart || e instanceof NavigationEnd)
+    ).subscribe(event => {
+      this.isNavigating.set(event instanceof NavigationStart);
+    });
+  }
+}
+```

+            <ol>
+                <li><a routerLink="/">Home</a></li>
+                @for (crumb of breadcrumbService.breadcrumbs(); track crumb.url) {

+        </nav>
+    `,
+})
+export class BreadcrumbCmpt {
+    breadcrumbService = inject(Breadcrumb);
+}
+```
+
+## Tab Navigation
+
+```typescript
+// tabs-layout.component.ts
+@Component({
+  imports: [RouterOutlet, RouterLink, RouterLinkActive],
+  template: `
+    <div class="tabs">
+      @for (tab of tabs; track tab.path) {
+        <a
+          [routerLink]="tab.path"
+          routerLinkActive="active"
+          [routerLinkActiveOptions]="{ exact: tab.exact }"
+        >
+          {{ tab.label }}
+        </a>
+      }
+    </div>
+    <div class="tab-content">
+      <router-outlet />
+    </div>
+  `,
+})
+export class TabsLayout {
+  tabs = [
+    { path: './', label: 'Overview', exact: true },
+    { path: 'details', label: 'Details', exact: false },
+    { path: 'settings', label: 'Settings', exact: false },
+  ];
+}
+
+// Routes
+{
+  path: 'account',
+  component: TabsLayout,
+  children: [
+    { path: '', component: AccountOverview },
+    { path: 'details', component: AccountDetails },
+    { path: 'settings', component: AccountSettings },
+  ],
+}
+```
+
+## Modal Routes
+
+Using auxiliary outlets for modals:
+
+```typescript
+// Routes
+export const routes: Routes = [
+  { path: 'products', component: ProductList },
+  { path: 'product-modal/:id', component: ProductModal, outlet: 'modal' },
+];
+
+// App template
+@Component({
+  template: `
+    <router-outlet />
+    <router-outlet name="modal" />
+  `,
+})
+export class App {}
+
+// Open modal
+this.router.navigate([{ outlets: { modal: ['product-modal', productId] } }]);
+
+// Close modal
+this.router.navigate([{ outlets: { modal: null } }]);
+
+// Link to open modal
+<a [routerLink]="[{ outlets: { modal: ['product-modal', product.id] } }]">
+  View Details
+</a>
+```
+
+## Preloading Strategies
+
+### Built-in Strategies
+
+```typescript
+import { provideRouter, withPreloading, PreloadAllModules, NoPreloading } from '@angular/router';
+
+// Preload all lazy modules
+provideRouter(routes, withPreloading(PreloadAllModules));
+
+// No preloading (default)
+provideRouter(routes, withPreloading(NoPreloading));
+```
+
+### Custom Preloading Strategy
+
+```typescript
+// selective-preload.strategy.ts
+@Injectable({ providedIn: 'root' })
+export class SelectivePreloadStrategy implements PreloadingStrategy {
+  preload(route: Route, load: () => Observable<any>): Observable<any> {
+    // Only preload routes marked with data.preload = true
+    if (route.data?.['preload']) {
+      return load();
+    }
+    return of(null);
+  }
+}
+
+// Routes
+{
+  path: 'dashboard',
+  loadComponent: () => import('./dashboard.component'),
+  data: { preload: true }, // Will be preloaded
+}
+
+// Config
+provideRouter(routes, withPreloading(SelectivePreloadStrategy))
+```
+
+### Network-Aware Preloading
+
+```typescript
+@Injectable({ providedIn: 'root' })
+export class NetworkAwarePreloadStrategy implements PreloadingStrategy {
+    preload(route: Route, load: () => Observable<any>): Observable<any> {
+        // Check network conditions
+        const connection = (navigator as any).connection;
+
+        if (connection) {
+            // Don't preload on slow connections
+            if (connection.saveData || connection.effectiveType === '2g') {
+                return of(null);
+            }
+        }
+
+        // Preload if marked
+        if (route.data?.['preload']) {
+            return load();
+        }
+
+        return of(null);
+    }
+}
+```
+
+## Route Animations
+
+```typescript
+// app.routes.ts
+export const routes: Routes = [
+    { path: 'home', component: Home, data: { animation: 'HomePage' } },
+    { path: 'about', component: About, data: { animation: 'AboutPage' } },
+];
+
+// app.component.ts
+@Component({
+    imports: [RouterOutlet],
+    template: `
+        <div [@routeAnimations]="getRouteAnimationData()">
+            <router-outlet />
+        </div>
+    `,
+    animations: [
+        trigger('routeAnimations', [
+            transition('HomePage <=> AboutPage', [
+                style({ position: 'relative' }),
+                query(':enter, :leave', [
+                    style({
+                        position: 'absolute',

+                        left: 0,
+                        width: '100%',
+                    }),
+                ]),
+                query(':enter', [style({ left: '-100%' })]),
+                query(':leave', animateChild()),
+                group([
+                    query(':leave', [animate('300ms ease-out', style({ left: '100%' }))]),
+                    query(':enter', [animate('300ms ease-out', style({ left: '0%' }))]),
+                ]),
+            ]),
+        ]),
+    ],
+})
+export class AppMain {
+    getRouteAnimationData() {
+        return this.route.firstChild?.snapshot.data['animation'];
+    }
+}
+```
+
+## Scroll Position Restoration
+
+```typescript
+// app.config.ts
+import { provideRouter, withInMemoryScrolling, withRouterConfig } from '@angular/router';
+
+provideRouter(
+    routes,
+    withInMemoryScrolling({
+        scrollPositionRestoration: 'enabled', // or 'top'
+        anchorScrolling: 'enabled',
+    }),

+description: Implement signal-based reactive state management in Angular v20+. Use for creating reactive state with signal(), derived state with computed(), dependent state with linkedSignal(), and side effects with effect(). Triggers on state management questions, converting from BehaviorSubject/Observable patterns to signals, or implementing reactive data flows.
+---
+
+# Angular Signals
+
+Signals are Angular's reactive primitive for state management. They provide synchronous, fine-grained reactivity.
+
+## Core Signal APIs
+
+### signal() - Writable State
+
+```typescript
+import { signal } from '@angular/core';
+
+// Create writable signal
+const count = signal(0);
+
+// Read value
+console.log(count()); // 0
+
+// Set new value
+count.set(5);
+
+// Update based on current value
+count.update((c) => c + 1);
+
+// With explicit type
+const user = signal<User | null>(null);
+user.set({ id: 1, name: 'Alice' });
+```
+
+### computed() - Derived State
+
+```typescript
+import { signal, computed } from '@angular/core';
+
+const firstName = signal('John');
+const lastName = signal('Doe');
+
+// Derived signal - automatically updates when dependencies change
+const fullName = computed(() => `${firstName()} ${lastName()}`);
+
+console.log(fullName()); // "John Doe"
+firstName.set('Jane');
+console.log(fullName()); // "Jane Doe"
+
+// Computed with complex logic
+const items = signal<Item[]>([]);
+const filter = signal('');
+
+const filteredItems = computed(() => {
+    const query = filter().toLowerCase();
+    return items().filter((item) => item.name.toLowerCase().includes(query));
+});
+
+const totalPrice = computed(() => filteredItems().reduce((sum, item) => sum + item.price, 0));
+```
+
+### linkedSignal() - Dependent State with Reset
+
+```typescript
+import { signal, linkedSignal } from '@angular/core';
+
+const options = signal(['A', 'B', 'C']);
+
+// Resets to first option when options change
+const selected = linkedSignal(() => options()[0]);
+
+console.log(selected()); // "A"
+selected.set('B'); // User selects B
+console.log(selected()); // "B"
+options.set(['X', 'Y']); // Options change
+console.log(selected()); // "X" - auto-reset to first
+
+// With previous value access
+const items = signal<Item[]>([]);
+
+const selectedItem = linkedSignal<Item[], Item | null>({
+    source: () => items(),
+    computation: (newItems, previous) => {
+        // Try to preserve selection if item still exists
+        const prevItem = previous?.value;
+        if (prevItem && newItems.some((i) => i.id === prevItem.id)) {
+            return prevItem;
+        }
+        return newItems[0] ?? null;
+    },
+});
+```
+
+### effect() - Side Effects
+
+```typescript
+import { signal, effect, inject, DestroyRef } from '@angular/core';
+
+@Component({...})
+export class Search {
+  query = signal('');
+
+  constructor() {
+    // Effect runs when query changes
+    effect(() => {
+      console.log('Search query:', this.query());
+    });
+
+    // Effect with cleanup
+    effect((onCleanup) => {
+      const timer = setInterval(() => {
+        console.log('Current query:', this.query());
+      }, 1000);
+
+      onCleanup(() => clearInterval(timer));
+    });
+  }
+}
+```
+
+**Effect rules:**
+
+- Run in injection context (constructor or with `runInInjectionContext`)
+- Automatically cleaned up when component destroys
+
+## Component State Pattern
+
+```typescript
+@Component({
+    selector: 'app-todo-list',
+    template: `
+        <input
+            [value]="newTodo()"
+            (input)="newTodo.set($any($event.target).value)" />
+        <button
+            [disabled]="!canAdd()"
+            (click)="addTodo()">
+            Add
+        </button>
+
+        <ul>
+            @for (todo of filteredTodos(); track todo.id) {
+                <li [class.done]="todo.done">
+                    {{ todo.text }}
+                    <button (click)="toggleTodo(todo.id)">Toggle</button>
+                </li>
+            }
+        </ul>
+
+        <p>{{ remaining() }} remaining</p>
+    `,
+})
+export class TodoList {
+    // State
+    todos = signal<Todo[]>([]);
+    newTodo = signal('');
+    filter = signal<'all' | 'active' | 'done'>('all');
+
+    // Derived state
+    canAdd = computed(() => this.newTodo().trim().length > 0);
+
+    filteredTodos = computed(() => {
+        const todos = this.todos();
+        switch (this.filter()) {
+            case 'active':
+                return todos.filter((t) => !t.done);
+            case 'done':
+                return todos.filter((t) => t.done);
+            default:
+                return todos;
+        }
+    });
+
+    remaining = computed(() => this.todos().filter((t) => !t.done).length);
+
+    // Actions
+    addTodo() {
+        const text = this.newTodo().trim();
+        if (text) {
+            this.todos.update((todos) => [...todos, { id: crypto.randomUUID(), text, done: false }]);
+            this.newTodo.set('');
+        }
+    }
+
+    toggleTodo(id: string) {
+        this.todos.update((todos) => todos.map((t) => (t.id === id ? { ...t, done: !t.done } : t)));
+    }
+}
+```
+
+## RxJS Interop
+
+### toSignal() - Observable to Signal
+
+```typescript
+import { toSignal } from '@angular/core/rxjs-interop';
+import { interval } from 'rxjs';
+
+@Component({...})
+export class Timer {
+  private http = inject(HttpClient);
+
+  // From observable - requires initial value or allowUndefined
+  counter = toSignal(interval(1000), { initialValue: 0 });
+
+  // From HTTP - undefined until loaded
+  users = toSignal(this.http.get<User[]>('/api/users'));
+
+  // With requireSync for synchronous observables (BehaviorSubject)
+  private user$ = new BehaviorSubject<User | null>(null);
+  currentUser = toSignal(this.user$, { requireSync: true });
+}
+```
+
+### toObservable() - Signal to Observable
+
+```typescript
+import { toObservable } from '@angular/core/rxjs-interop';
+import { switchMap, debounceTime } from 'rxjs';
+
+@Component({...})
+export class Search {
+  query = signal('');
+
+  private http = inject(HttpClient);
+
+  // Convert signal to observable for RxJS operators
+  results = toSignal(
+    toObservable(this.query).pipe(
+      debounceTime(300),
+      switchMap(q => this.http.get<Result[]>(`/api/search?q=${q}`))
+    ),
+    { initialValue: [] }
+  );
+}
+```
+
+## Signal Equality
+
+```typescript
+// Custom equality function
+const user = signal<User>({ id: 1, name: 'Alice' }, { equal: (a, b) => a.id === b.id });
+
+// Only triggers updates when ID changes
+user.set({ id: 1, name: 'Alice Updated' }); // No update
+user.set({ id: 2, name: 'Bob' }); // Triggers update
+```
+
+## Untracked Reads
+
+```typescript
+import { untracked } from '@angular/core';
+
+const a = signal(1);
+const b = signal(2);
+
+// Only depends on 'a', not 'b'
+const result = computed(() => {
+    const aVal = a();
+    const bVal = untracked(() => b());
+    return aVal + bVal;
+});
+```
+
+## Service State Pattern
+
+```typescript
+@Injectable({ providedIn: 'root' })
+export class Auth {
+    // Private writable state
+    private _user = signal<User | null>(null);
+    private _loading = signal(false);
+
+    // Public read-only signals
+    readonly user = this._user.asReadonly();
+    readonly loading = this._loading.asReadonly();
+    readonly isAuthenticated = computed(() => this._user() !== null);
+
+    private http = inject(HttpClient);
+
+    async login(credentials: Credentials): Promise<void> {
+        this._loading.set(true);
+        try {
+            const user = await firstValueFrom(this.http.post<User>('/api/login', credentials));
+            this._user.set(user);
+        } finally {
+            this._loading.set(false);
+        }
+    }
+
+    logout(): void {
+        this._user.set(null);
+    }
+}
+```

+## Resource API
+
+The `resource()` API handles async data fetching with signals:
+
+```typescript
+import { resource, signal, computed } from '@angular/core';
+
+@Component({...})
+export class UserProfile {
+  userId = signal<string>('');
+
+  // Resource fetches data when params change
+  userResource = resource({
+    params: () => ({ id: this.userId() }),
+    loader: async ({ params, abortSignal }) => {
+      const response = await fetch(`/api/users/${params.id}`, {
+        signal: abortSignal,
+      });
+      return response.json() as Promise<User>;
+    },
+  });
+
+  // Access resource state
+  user = computed(() => this.userResource.value());
+  isLoading = computed(() => this.userResource.isLoading());
+  error = computed(() => this.userResource.error());
+}
+```
+
+### Resource Status
+
+```typescript
+const userResource = resource({...});
+
+// Status signals
+userResource.value();      // Current value or undefined
+userResource.hasValue();   // Boolean - has resolved value
+userResource.error();      // Error or undefined
+userResource.isLoading();  // Boolean - currently loading
+userResource.status();     // 'idle' | 'loading' | 'reloading' | 'resolved' | 'error' | 'local'
+
+// Manual reload
+userResource.reload();
+
+// Local updates
+userResource.set(newValue);
+userResource.update(current => ({ ...current, name: 'Updated' }));
+```
+
+### Resource with Default Value
+
+```typescript
+const todosResource = resource({
+    defaultValue: [] as Todo[],
+    params: () => ({ filter: this.filter() }),
+    loader: async ({ params }) => {
+        const response = await fetch(`/api/todos?filter=${params.filter}`);
+        return response.json();
+    },
+});
+
+// value() returns Todo[] (never undefined due to defaultValue)
+```
+
+### Conditional Loading
+
+```typescript
+const userId = signal<string | null>(null);
+
+const userResource = resource({
+    params: () => {
+        const id = userId();
+        // Return undefined to skip loading
+        return id ? { id } : undefined;
+    },
+    loader: async ({ params }) => {
+        return fetch(`/api/users/${params.id}`).then((r) => r.json());
+    },
+});
+// Status is 'idle' when params returns undefined
+```
+
+## Signal Store Pattern
+
+For complex state, create a dedicated store:
+
+```typescript
+interface ProductState {
+    products: Product[];
+    selectedId: string | null;
+    filter: string;
+    loading: boolean;
+    error: string | null;
+}
+
+@Injectable({ providedIn: 'root' })
+export class ProductSt {
+    // Private state
+    private state = signal<ProductState>({
+        products: [],
+        selectedId: null,
+        filter: '',
+        loading: false,
+        error: null,
+    });
+
+    // Selectors (computed signals)
+    readonly products = computed(() => this.state().products);
+    readonly selectedId = computed(() => this.state().selectedId);
+    readonly filter = computed(() => this.state().filter);
+    readonly loading = computed(() => this.state().loading);
+    readonly error = computed(() => this.state().error);
+
+    readonly filteredProducts = computed(() => {
+        const { products, filter } = this.state();
+        if (!filter) return products;
+        return products.filter((p) => p.name.toLowerCase().includes(filter.toLowerCase()));
+    });
+
+    readonly selectedProduct = computed(() => {
+        const { products, selectedId } = this.state();
+        return products.find((p) => p.id === selectedId) ?? null;
+    });
+
+    private http = inject(HttpClient);
+
+    // Actions
+    setFilter(filter: string): void {
+        this.state.update((s) => ({ ...s, filter }));
+    }
+
+    selectProduct(id: string | null): void {
+        this.state.update((s) => ({ ...s, selectedId: id }));
+    }
+
+    async loadProducts(): Promise<void> {
+        this.state.update((s) => ({ ...s, loading: true, error: null }));
+
+        try {
+            const products = await firstValueFrom(this.http.get<Product[]>('/api/products'));
+            this.state.update((s) => ({ ...s, products, loading: false }));
+        } catch (err) {
+            this.state.update((s) => ({
+                ...s,
+                loading: false,
+                error: 'Failed to load products',
+            }));
+        }
+    }
+
+    async addProduct(product: Omit<Product, 'id'>): Promise<void> {
+        const newProduct = await firstValueFrom(this.http.post<Product>('/api/products', product));
+        this.state.update((s) => ({
+            ...s,
+            products: [...s.products, newProduct],
+        }));
+    }
+}
+```
+
+## Form State with Signals
+
+```typescript
+interface FormState<T> {
+  value: T;
+  touched: boolean;
+  dirty: boolean;
+  valid: boolean;
+  errors: string[];
+}
+
+function createFormField<T>(
+  initialValue: T,
+  validators: ((value: T) => string | null)[] = []
+) {
+  const value = signal(initialValue);
+  const touched = signal(false);
+  const dirty = signal(false);
+
+  const errors = computed(() => {
+    return validators
+      .map(v => v(value()))
+      .filter((e): e is string => e !== null);
+  });
+
+  const valid = computed(() => errors().length === 0);
+
+  return {
+    value,
+    touched: touched.asReadonly(),
+    dirty: dirty.asReadonly(),
+    errors,

+description: Write unit and integration tests for Angular v20+ applications using Vitest or Jasmine with TestBed and modern testing patterns. Use for testing components with signals, OnPush change detection, services with inject(), and HTTP interactions. Triggers on test creation, testing signal-based components, mocking dependencies, or setting up test infrastructure. Don't use for E2E testing with Cypress or Playwright, or for testing non-Angular JavaScript/TypeScript code.
+---
+
+# Angular Testing
+
+Test Angular v20+ applications with Vitest (recommended) or Jasmine, focusing on signal-based components and modern patterns.
+
+## Vitest Setup (Angular v20+)
+
+Angular v20+ has native Vitest support through the `@angular/build` package.
+
+```bash
+npm install -D vitest jsdom
+```
+
+Configure in angular.json:
+
+```json
+{
+    "projects": {
+        "your-app": {
+            "architect": {
+                "test": {
+                    "builder": "@angular/build:unit-test",
+                    "options": {
+                        "tsConfig": "tsconfig.spec.json",
+                        "buildTarget": "your-app:build"
+                    }
+                }
+            }
+        }
+    }
+}
+```
+
+Run tests:
+
+```bash
+ng test              # Run tests
+ng test --watch      # Watch mode
+ng test --code-coverage  # With coverage
+```
+
+For Vitest migration from Jasmine and advanced configuration, see [references/vitest-migration.md](references/vitest-migration.md).
+
+## Basic Component Test
+
+```typescript
+import { describe, it, expect, beforeEach } from 'vitest';
+import { ComponentFixture, TestBed } from '@angular/core/testing';
+import { Counter } from './counter.component';
+
+describe('Counter', () => {
+    let component: Counter;
+    let fixture: ComponentFixture<Counter>;
+
+    beforeEach(async () => {
+        await TestBed.configureTestingModule({
+            imports: [Counter], // Standalone component
+        }).compileComponents();
+
+        fixture = TestBed.createComponent(Counter);
+        component = fixture.componentInstance;
+        fixture.detectChanges();
+    });
+
+    it('should create', () => {
+        expect(component).toBeTruthy();
+    });
+
+    it('should increment count', () => {
+        expect(component.count()).toBe(0);
+        component.increment();
+        expect(component.count()).toBe(1);
+    });
+
+    it('should display count in template', () => {
+        component.count.set(5);
+        fixture.detectChanges();
+
+        const element = fixture.nativeElement.querySelector('.count');
+        expect(element.textContent).toContain('5');
+    });
+});
+```
+
+## Testing Signals
+
+### Direct Signal Testing
+
+```typescript
+import { signal, computed } from '@angular/core';
+
+describe('Signal logic', () => {
+    it('should update computed when signal changes', () => {
+        const count = signal(0);
+        const doubled = computed(() => count() * 2);
+
+        expect(doubled()).toBe(0);
+
+        count.set(5);
+        expect(doubled()).toBe(10);
+
+        count.update((c) => c + 1);
+        expect(doubled()).toBe(12);
+    });
+});
+```
+
+### Testing Component Signals
+
+```typescript
+@Component({
+    selector: 'app-todo-list',
+    template: `
+        <ul>
+            @for (todo of filteredTodos(); track todo.id) {
+                <li>{{ todo.text }}</li>
+            }
+        </ul>
+        <p>{{ remaining() }} remaining</p>
+    `,
+})
+export class TodoList {
+    todos = signal<Todo[]>([]);
+    filter = signal<'all' | 'active' | 'done'>('all');
+
+    filteredTodos = computed(() => {
+        const todos = this.todos();
+        switch (this.filter()) {
+            case 'active':

+            default:
+                return todos;
+        }
+    });
+
+    remaining = computed(() => this.todos().filter((t) => !t.done).length);
+}
+
+describe('TodoList', () => {
+    let component: TodoList;
+    let fixture: ComponentFixture<TodoList>;
+
+    beforeEach(async () => {
+        await TestBed.configureTestingModule({
+            imports: [TodoList],
+        }).compileComponents();
+
+        fixture = TestBed.createComponent(TodoList);
+        component = fixture.componentInstance;
+    });
+
+    it('should filter active todos', () => {
+        component.todos.set([
+            { id: '1', text: 'Task 1', done: false },
+            { id: '2', text: 'Task 2', done: true },
+            { id: '3', text: 'Task 3', done: false },
+        ]);
+
+        component.filter.set('active');
+
+        expect(component.filteredTodos().length).toBe(2);
+        expect(component.remaining()).toBe(2);
+    });
+});
+```
+
+## Testing OnPush Components
+
+OnPush components require explicit change detection:
+
+```typescript
+@Component({
+    changeDetection: ChangeDetectionStrategy.OnPush,
+    template: `<span>{{ data().name }}</span>`,
+})
+export class OnPushCmpt {
+    data = input.required<{ name: string }>();
+}
+
+describe('OnPushCmpt', () => {
+    it('should update when input signal changes', () => {
+        const fixture = TestBed.createComponent(OnPushCmpt);
+
+        // Set input using setInput (for signal inputs)
+        fixture.componentRef.setInput('data', { name: 'Initial' });
+        fixture.detectChanges();
+
+        expect(fixture.nativeElement.textContent).toContain('Initial');
+
+        // Update input
+        fixture.componentRef.setInput('data', { name: 'Updated' });
+        fixture.detectChanges();
+
+        expect(fixture.nativeElement.textContent).toContain('Updated');
+    });
+});
+```
+
+## Testing Services
+
+### Basic Service Test
+
+```typescript
+@Injectable({ providedIn: 'root' })
+export class CounterService {
+    private _count = signal(0);
+    readonly count = this._count.asReadonly();
+
+    increment() {
+        this._count.update((c) => c + 1);
+    }
+    reset() {
+        this._count.set(0);
+    }
+}
+
+describe('CounterService', () => {
+    let service: CounterService;
+
+    beforeEach(() => {
+        TestBed.configureTestingModule({});
+        service = TestBed.inject(CounterService);
+    });
+
+    it('should increment count', () => {
+        expect(service.count()).toBe(0);
+        service.increment();
+        expect(service.count()).toBe(1);
+    });
+});
+```
+
+### Service with HTTP
+
+```typescript
+import { HttpTestingController, provideHttpClientTesting } from '@angular/common/http/testing';
+import { provideHttpClient } from '@angular/common/http';
+
+describe('UserService', () => {
+    let service: UserService;
+    let httpMock: HttpTestingController;
+
+    beforeEach(() => {
+        TestBed.configureTestingModule({
+            providers: [provideHttpClient(), provideHttpClientTesting()],
+        });
+
+        service = TestBed.inject(UserService);
+        httpMock = TestBed.inject(HttpTestingController);
+    });
+
+    afterEach(() => {
+        httpMock.verify(); // Verify no outstanding requests
+    });
+
+    it('should fetch user by id', () => {
+        const mockUser = { id: '1', name: 'Test User' };
+
+        service.getUser('1').subscribe((user) => {
+            expect(user).toEqual(mockUser);
+        });
+
+        const req = httpMock.expectOne('/api/users/1');
+        expect(req.request.method).toBe('GET');
+        req.flush(mockUser);
+    });
+});
+```
+
+## Mocking Dependencies
+
+### Using Vitest Mocks
+
+```typescript
+import { describe, it, expect, vi, beforeEach } from 'vitest';
+
+describe('UserProfile', () => {
+    const mockUserService = {
+        getUser: vi.fn(),
+        updateUser: vi.fn(),
+        user: signal<User | null>(null),
+    };
+
+    beforeEach(async () => {
+        vi.clearAllMocks();
+        mockUserService.getUser.mockReturnValue(of({ id: '1', name: 'Test' }));
+
+        await TestBed.configureTestingModule({
+            imports: [UserProfile],
+            providers: [{ provide: UserService, useValue: mockUserService }],
+        }).compileComponents();
+    });
+
+    it('should call getUser on init', () => {
+        const fixture = TestBed.createComponent(UserProfile);
+        fixture.detectChanges();
+
+        expect(mockUserService.getUser).toHaveBeenCalledWith('1');
+    });
+});
+```
+
+### Mock Signal-Based Service
+
+```typescript
+const mockAuth = {
+    user: signal<User | null>(null),
+    isAuthenticated: computed(() => mockAuth.user() !== null),
+    login: vi.fn(),
+    logout: vi.fn(),
+};
+
+beforeEach(async () => {
+    await TestBed.configureTestingModule({
+        imports: [ProtectedPage],
+        providers: [{ provide: AuthService, useValue: mockAuth }],
+    }).compileComponents();
+});
+
+it('should show content when authenticated', () => {
+    mockAuth.user.set({ id: '1', name: 'Test User' });
+
+    const fixture = TestBed.createComponent(ProtectedPage);
+    fixture.detectChanges();
+
+    expect(fixture.nativeElement.querySelector('.protected-content')).toBeTruthy();
+});
+```
+
+## Testing Inputs and Outputs
+
+```typescript
+@Component({
+    selector: 'app-item',
+    template: `<div (click)="select()">{{ item().name }}</div>`,
+})
+export class ItemCmpt {
+    item = input.required<Item>();
+    selected = output<Item>();
+
+    select() {
+        this.selected.emit(this.item());
+    }
+}
+
+describe('ItemCmpt', () => {
+    it('should emit selected event on click', () => {
+        const fixture = TestBed.createComponent(ItemCmpt);
+        const item: Item = { id: '1', name: 'Test Item' };
+
+        fixture.componentRef.setInput('item', item);
+        fixture.detectChanges();
+
+        let emittedItem: Item | undefined;
+        fixture.componentInstance.selected.subscribe((i) => (emittedItem = i));
+
+        fixture.nativeElement.querySelector('div').click();
+
+        expect(emittedItem).toEqual(item);
+    });
+});
+```
+
+## Testing Async Operations
+
+### Using fakeAsync
+
+```typescript
+import { fakeAsync, tick, flush } from '@angular/core/testing';
+
+it('should debounce search', fakeAsync(() => {
+    const fixture = TestBed.createComponent(SearchCmpt);
+    fixture.detectChanges();
+
+    fixture.componentInstance.query.set('test');
+
+    tick(300); // Advance time for debounce
+    fixture.detectChanges();
+
+    expect(fixture.componentInstance.results().length).toBeGreaterThan(0);
+
+    flush(); // Flush remaining timers
+}));
+```
+
+### Using waitForAsync
+
+```typescript
+import { waitForAsync } from '@angular/core/testing';
+
+it('should load data', waitForAsync(() => {
+    const fixture = TestBed.createComponent(DataCmpt);
+    fixture.detectChanges();
+
+    fixture.whenStable().then(() => {
+        fixture.detectChanges();
+        expect(fixture.componentInstance.data()).toBeDefined();
+    });
+}));
+```
+
+## Testing HTTP Resources
+
+```typescript
+@Component({
+    template: `
+        @if (userResource.isLoading()) {
+            <p>Loading...</p>
+        } @else if (userResource.hasValue()) {
+            <p>{{ userResource.value().name }}</p>
+        }
+    `,
+})
+export class UserCmpt {
+    userId = signal('1');
+    userResource = httpResource<User>(() => `/api/users/${this.userId()}`);
+}
+
+describe('UserCmpt', () => {

+## Vitest Advanced Patterns
+
+### Snapshot Testing
+
+```typescript
+import { describe, it, expect } from 'vitest';
+
+describe('UserCard', () => {
+    it('should match snapshot', () => {
+        const fixture = TestBed.createComponent(UserCard);
+        fixture.componentRef.setInput('user', {
+            id: '1',
+            name: 'John',
+            email: 'john@example.com',
+        });
+        fixture.detectChanges();
+
+        expect(fixture.nativeElement.innerHTML).toMatchSnapshot();
+    });
+});
+```
+
+### Parameterized Tests
+
+```typescript
+import { describe, it, expect } from 'vitest';
+
+describe('Validator', () => {
+    it.each([
+        { input: '', expected: false },
+        { input: 'test', expected: false },
+        { input: 'test@example.com', expected: true },
+        { input: 'invalid@', expected: false },
+    ])('should validate email "$input" as $expected', ({ input, expected }) => {
+        expect(isValidEmail(input)).toBe(expected);
+    });
+});
+```
+
+### Testing with Fake Timers
+
+```typescript
+import { describe, it, expect, vi, beforeEach, afterEach } from 'vitest';
+
+describe('Debounced Search', () => {
+    beforeEach(() => {

+
+    it('should debounce search input', async () => {
+        const fixture = TestBed.createComponent(Search);
+        fixture.detectChanges();
+
+        fixture.componentInstance.query.set('test');
+
+        // Search not called yet
+        expect(fixture.componentInstance.results()).toEqual([]);
+
+        // Advance timers

+
+        expect(fixture.componentInstance.results().length).toBeGreaterThan(0);
+    });
+});
+```
+
+### Module Mocking
+
+```typescript
+import { describe, it, expect, vi } from 'vitest';
+
+// Mock entire module
+vi.mock('./analytics.service', () => ({
+    Analytics: class {
+        track = vi.fn();
+        identify = vi.fn();
+    },
+}));
+
+describe('with mocked analytics', () => {

+        const analytics = TestBed.inject(Analytics);
+
+        fixture.detectChanges();
+
+        expect(analytics.track).toHaveBeenCalledWith('dashboard_viewed');
+    });
+});
+```
+
+### Testing Async/Await
+
+```typescript
+import { describe, it, expect, vi } from 'vitest';
+
+describe('User', () => {
+    it('should load user data', async () => {
+        const mockUser = { id: '1', name: 'Test' };

+
+        const userPromise = service.loadUser('1');
+
+        httpMock.expectOne('/api/users/1').flush(mockUser);
+
+        const user = await userPromise;
+        expect(user).toEqual(mockUser);
+    });
+});
+```
+
+### Coverage Configuration
+
+```typescript
+// vite.config.ts
+export default defineConfig({
+    test: {
+        coverage: {
+            provider: 'v8',

+
+### Vitest UI Mode
+
+```bash
+# Run with UI
+npx vitest --ui
+
+# Open UI at specific port
+npx vitest --ui --port 51204
+```
+
+### Concurrent Tests
+
+```typescript
+import { describe, it, expect } from 'vitest';
+
+// Run tests in this describe block concurrently
+describe.concurrent('API calls', () => {
+    it('should fetch users', async () => {
+        // ...

+
+## Component Harnesses
+
+Use Angular CDK component harnesses for more maintainable tests:
+
+### Creating a Harness
+
+```typescript
+import { ComponentHarness, HarnessPredicate } from '@angular/cdk/testing';
+
+export class CounterHarn extends ComponentHarness {
+    static hostSelector = 'app-counter';
+
+    // Locators
+    private getIncrementButton = this.locatorFor('button.increment');
+    private getDecrementButton = this.locatorFor('button.decrement');
+    private getCountDisplay = this.locatorFor('.count');
+
+    // Actions
+    async increment(): Promise<void> {
+        const button = await this.getIncrementButton();
+        await button.click();
+    }
+
+    async decrement(): Promise<void> {
+        const button = await this.getDecrementButton();
+        await button.click();
+    }
+
+    // Queries
+    async getCount(): Promise<number> {
+        const display = await this.getCountDisplay();
+        const text = await display.text();
+        return parseInt(text, 10);
+    }
+
+    // Filter factory
+    static with(options: { count?: number } = {}): HarnessPredicate<CounterHarn> {
+        return new HarnessPredicate(CounterHarn, options).addOption('count', options.count, async (harness, count) => {
+            return (await harness.getCount()) === count;
+        });
+    }
+}
+```
+
+### Using Harnesses in Tests
+
+```typescript
+import { TestbedHarnessEnvironment } from '@angular/cdk/testing/testbed';
+
+describe('Counter with Harness', () => {
+    let loader: HarnessLoader;
+
+    beforeEach(async () => {

+        }).compileComponents();
+
+        const fixture = TestBed.createComponent(Counter);
+        loader = TestbedHarnessEnvironment.loader(fixture);
+    });
+
+    it('should increment count', async () => {
+        const counter = await loader.getHarness(CounterHarn);
+
+        expect(await counter.getCount()).toBe(0);
+
+        await counter.increment();
+        expect(await counter.getCount()).toBe(1);
+
+        await counter.increment();
+        expect(await counter.getCount()).toBe(2);
+    });
+
+    it('should find counter with specific count', async () => {
+        const counter = await loader.getHarness(CounterHarn);
+        await counter.increment();
+        await counter.increment();
+
+        // Find counter with count of 2
+        const counterWith2 = await loader.getHarness(CounterHarn.with({ count: 2 }));
+        expect(counterWith2).toBeTruthy();
+    });
+});
+```
+
+## Testing Router

+# Vitest Setup and Migration Guide
+
+## Vitest vs Jasmine Comparison
+
+| Feature    | Vitest                  | Jasmine/Karma         |
+| ---------- | ----------------------- | --------------------- |
+| Speed      | Faster (native ESM)     | Slower                |
+| Watch mode | Instant feedback        | Slower rebuilds       |
+| Mocking    | `vi.fn()`, `vi.mock()`  | `jasmine.createSpy()` |
+| Assertions | `expect()` (Chai-style) | `expect()` (Jasmine)  |
+| UI         | Built-in UI mode        | Karma browser         |
+| Config     | `angular.json`          | `karma.conf.js`       |
+
+## Migration from Jasmine to Vitest
+
+### Spy Migration
+
+```typescript
+// Jasmine
+const spy = jasmine.createSpy('callback');
+spy.and.returnValue('value');
+expect(spy).toHaveBeenCalledWith('arg');
+
+// Vitest
+const spy = vi.fn();
+spy.mockReturnValue('value');
+expect(spy).toHaveBeenCalledWith('arg');
+```
+
+### SpyOn Migration
+
+```typescript
+// Jasmine
+spyOn(service, 'method').and.returnValue(of(data));
+
+// Vitest
+vi.spyOn(service, 'method').mockReturnValue(of(data));
+```
+
+### createSpyObj Migration
+
+```typescript
+// Jasmine
+const mockService = jasmine.createSpyObj('UserService', ['getUser', 'updateUser']);
+mockService.getUser.and.returnValue(of({ id: '1', name: 'Test' }));
+
+// Vitest
+const mockService = {
+    getUser: vi.fn(),
+    updateUser: vi.fn(),
+};
+mockService.getUser.mockReturnValue(of({ id: '1', name: 'Test' }));
+```
+
+### Async Testing Migration
+
+```typescript
+// Jasmine - using done callback
+it('should load data', (done) => {
+    service.loadData().subscribe((data) => {
+        expect(data).toBeDefined();
+        done();
+    });
+});
+
+// Vitest - using async/await
+it('should load data', async () => {
+    const data = await firstValueFrom(service.loadData());
+    expect(data).toBeDefined();
+});
+```
+
+### Clock/Timer Migration
+
+```typescript
+// Jasmine
+jasmine.clock().install();
+jasmine.clock().tick(1000);
+jasmine.clock().uninstall();
+
+// Vitest
+vi.useFakeTimers();
+vi.advanceTimersByTime(1000);
+vi.useRealTimers();
+```
+
+## Vitest Configuration Details
+
+### Full angular.json Configuration
+
+```json
+{
+    "projects": {
+        "your-app": {
+            "architect": {
+                "test": {
+                    "builder": "@angular/build:unit-test",
+                    "options": {
+                        "tsConfig": "tsconfig.spec.json",
+                        "buildTarget": "your-app:build"
+                    }
+                }
+            }
+        }
+    }
+}
+```
+
+### tsconfig.spec.json
+
+```json
+{
+    "extends": "./tsconfig.json",
+    "compilerOptions": {
+        "types": ["vitest/globals"]
+    },
+    "include": ["src/**/*.spec.ts"]
+}
+```
+
+### Optional vite.config.ts
+
+For advanced configuration, create a `vite.config.ts`:
+
+```typescript
+import { defineConfig } from 'vitest/config';
+
+export default defineConfig({
+    test: {
+        globals: true,
+        environment: 'jsdom',
+        include: ['src/**/*.spec.ts'],
+        coverage: {
+            provider: 'v8',
+            reporter: ['text', 'html', 'lcov'],
+            exclude: ['node_modules/', 'src/test-setup.ts', '**/*.spec.ts', '**/*.d.ts'],
+        },
+    },
+});
+```
+
+## Running Vitest
+
+```bash
+# Run tests
+ng test
+
+# Watch mode
+ng test --watch
+
+# Coverage
+ng test --code-coverage
+
+# Run specific file pattern
+ng test --include='**/user*.spec.ts'
+
+# CI mode (single run)
+ng test --watch=false
+```

+name: angular-tooling
+description: Use Angular CLI and development tools effectively in Angular v20+ projects. Use for project setup, code generation, building, testing, and configuration. Triggers on creating new projects, generating components/services/modules, configuring builds, running tests, or optimizing production builds. Don't use for Nx workspace commands, custom Webpack configurations, or non-Angular CLI build systems like Vite standalone or esbuild direct usage.

+## Custom Schematics
+
+### Generate Schematic Collection
+
+```bash
+# Install schematics CLI
+npm install -g @angular-devkit/schematics-cli
+
+# Create schematic collection
+schematics blank --name=my-schematics
+```
+
+### Simple Component Schematic
+
+```typescript
+// src/my-component/index.ts
+import { Rule, SchematicContext, Tree, apply, url, template, move, mergeWith } from '@angular-devkit/schematics';
+import { strings } from '@angular-devkit/core';
+
+export function myComponent(options: { name: string; path: string }): Rule {
+    return (tree: Tree, context: SchematicContext) => {
+        const templateSource = apply(url('./files'), [
+            template({
+                ...options,
+                ...strings,
+            }),
+            move(options.path),
+        ]);
+
+        return mergeWith(templateSource)(tree, context);
+    };
+}
+```
+
+### Use Custom Schematics
+
+```bash
+# Link locally
+npm link ./my-schematics
+
+# Use
+ng generate my-schematics:my-component --name=test --path=src/app
+```
+
+## Build Optimization
+
+### Budget Configuration
+
+```json
+{
+    "budgets": [
+        {
+            "type": "initial",
+            "maximumWarning": "500kB",
+            "maximumError": "1MB"
+        },
+        {
+            "type": "anyComponentStyle",
+            "maximumWarning": "4kB",
+            "maximumError": "8kB"
+        },
+        {
+            "type": "anyScript",
+            "maximumWarning": "100kB",
+            "maximumError": "200kB"
+        }
+    ]
+}
+```
+
+### Differential Loading
+
+Automatic in v20+ - builds for modern browsers by default.
+
+```json
+// .browserslistrc
+last 2 Chrome versions
+last 2 Firefox versions
+last 2 Safari versions
+last 2 Edge versions
+```
+
+### Code Splitting
+
+```typescript
+// Lazy load routes for automatic code splitting
+export const routes: Routes = [
+    {
+        path: 'admin',
+        loadChildren: () => import('./admin/admin.routes').then((m) => m.adminRoutes),
+    },
+    {
+        path: 'reports',
+        loadComponent: () => import('./reports/reports.component').then((m) => m.Reports),
+    },
+];
+```
+
+### Tree Shaking
+
+Ensure proper imports for tree shaking:
+
+```typescript
+// Good - tree shakeable
+import { map, filter } from 'rxjs';
+
+// Avoid - imports entire library
+import * as rxjs from 'rxjs';
+```
+
+### Preload Strategy
+
+```typescript
+// app.config.ts
+import { provideRouter, withPreloading, PreloadAllModules } from '@angular/router';
+
+export const appConfig: ApplicationConfig = {
+    providers: [provideRouter(routes, withPreloading(PreloadAllModules))],
+};
+```
+
+## Multi-Project Workspace
+
+### Create Workspace
+
+```bash
+# Create empty workspace
+ng new my-workspace --create-application=false
+
+cd my-workspace
+
+# Add applications
+ng generate application main-app
+ng generate application admin-app
+
+# Add library
+ng generate library shared-ui
+ng generate library data-access
+```
+
+### Workspace Structure
+
+```

+    "lib": {
+        "entryFile": "src/public-api.ts"
+    }
+}
+```
+
+### Using Library in App
+
+```typescript
+// After building library: ng build shared-ui
+import { Button } from 'shared-ui';
+
+@Component({
+    imports: [Button],
+    template: `<lib-button>Click</lib-button>`,
+})
+export class App {}

+
+## Path Aliases
+
+### Configure tsconfig.json
+
+```json
+{
+    "compilerOptions": {
+        "baseUrl": ".",
+        "paths": {
+            "@app/*": ["src/app/*"],
+            "@env/*": ["src/environments/*"],
+            "@shared/*": ["src/app/shared/*"],
+            "@features/*": ["src/app/features/*"],
+            "@core/*": ["src/app/core/*"]
+        }
+    }
+}
+```
+
+### Usage
+
+```typescript
+// Instead of relative imports
+import { User } from '../../../core/services/user.service';
+
+// Use path alias
+import { User } from '@core/services/user.service';
+```
+
+## Proxy Configuration
+
+### Development Proxy
+
+```json
+// proxy.conf.json
+{
+    "/api": {
+        "target": "http://localhost:3000",

+        "changeOrigin": true
+    },
+    "/auth": {
+        "target": "http://localhost:4000",
+        "secure": false,
+        "pathRewrite": {
+            "^/auth": ""
+        }
+    }
+}
+```

+```bash
+ng serve --proxy-config proxy.conf.json
+```
+
+## Custom Builders
+
+### Using esbuild (Default in v20+)
+
+```json
+{
+    "architect": {
+        "build": {
+            "builder": "@angular-devkit/build-angular:application",
+            "options": {

+---
+
+This skill guides creation of distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.
+
+The user provides frontend requirements: a component, page, application, or interface to build. They may include context about the purpose, audience, or technical constraints.
+
+## Design Thinking
+
+Before coding, understand the context and commit to a BOLD aesthetic direction:
+
+- **Purpose**: What problem does this interface solve? Who uses it?
+- **Tone**: Pick an extreme: brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian, etc. There are so many flavors to choose from. Use these for inspiration but design one that is true to the aesthetic direction.
+- **Constraints**: Technical requirements (framework, performance, accessibility).
+- **Differentiation**: What makes this UNFORGETTABLE? What's the one thing someone will remember?
+
+**CRITICAL**: Choose a clear conceptual direction and execute it with precision. Bold maximalism and refined minimalism both work - the key is intentionality, not intensity.
+
+Then implement working code (HTML/CSS/JS, React, Vue, etc.) that is:
+
+- Production-grade and functional
+- Visually striking and memorable
+- Cohesive with a clear aesthetic point-of-view
+- Meticulously refined in every detail
+
+## Frontend Aesthetics Guidelines
+
+Focus on:
+
+- **Typography**: Choose fonts that are beautiful, unique, and interesting. Avoid generic fonts like Arial and Inter; opt instead for distinctive choices that elevate the frontend's aesthetics; unexpected, characterful font choices. Pair a distinctive display font with a refined body font.
+- **Color & Theme**: Commit to a cohesive aesthetic. Use CSS variables for consistency. Dominant colors with sharp accents outperform timid, evenly-distributed palettes.
+- **Motion**: Use animations for effects and micro-interactions. Prioritize CSS-only solutions for HTML. Use Motion library for React when available. Focus on high-impact moments: one well-orchestrated page load with staggered reveals (animation-delay) creates more delight than scattered micro-interactions. Use scroll-triggering and hover states that surprise.
+- **Spatial Composition**: Unexpected layouts. Asymmetry. Overlap. Diagonal flow. Grid-breaking elements. Generous negative space OR controlled density.
+- **Backgrounds & Visual Details**: Create atmosphere and depth rather than defaulting to solid colors. Add contextual effects and textures that match the overall aesthetic. Apply creative forms like gradient meshes, noise textures, geometric patterns, layered transparencies, dramatic shadows, decorative borders, custom cursors, and grain overlays.
+
+NEVER use generic AI-generated aesthetics like overused font families (Inter, Roboto, Arial, system fonts), cliched color schemes (particularly purple gradients on white backgrounds), predictable layouts and component patterns, and cookie-cutter design that lacks context-specific character.
+
+Interpret creatively and make unexpected choices that feel genuinely designed for the context. No design should be the same. Vary between light and dark themes, different fonts, different aesthetics. NEVER converge on common choices (Space Grotesk, for example) across generations.
+
+**IMPORTANT**: Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code with extensive animations and effects. Minimalist or refined designs need restraint, precision, and careful attention to spacing, typography, and subtle details. Elegance comes from executing the vision well.
+
+Remember: Claude is capable of extraordinary creative work. Don't hold back, show what can truly be created when thinking outside the box and committing fully to a distinctive vision.
