What’s New in Angular 21: Latest Features & Examples

1. HttpClient Is Now Provided by Default

Angular now includes HttpClient automatically in standalone applications. This aligns with the goal of reducing boilerplate and making common features work out-of-the-box.

constructor(private http: HttpClient) {}						
ngOnInit() {	
  this.http.get('/api/products').subscribe();
}
							

2. NgClass Migration Toward Style Bindings (New Schematics)

Angular 21 introduces schematics to help projects move from NgClass to direct class bindings, which are faster, more type-safe, and easier to read.

<div [ngClass]="{ active: isActive }"></div>
							

<div [class.active]="isActive"></div>
							

3. NgStyle Migration to Style Bindings (New Schematics)

Just like NgClass, Angular wants developers to move toward direct style bindings.

<div [ngStyle]="{ 'padding': pad }"></div>
							

<div [style.padding.px]="pad"></div>
							

3. NgStyle Migration to Style Bindings (New Schematics)

Just like NgClass, Angular wants developers to move toward direct style bindings.

<div [ngStyle]="{ 'padding': pad }"></div>
							

<div [style.padding.px]="pad"></div>
							

4. KeyValue Pipe Now Supports Optional Keys

The KeyValue pipe becomes more flexible by handling optional or missing keys gracefully.

details = { name: 'Laptop', price: undefined };
<div *ngFor="let item of details | keyvalue">
  {{ item.key }} : {{ item.value }}
</div>
							

5. Enhanced HttpResponse & HttpErrorResponse

Angular 21 refines the structure and typing of HTTP responses.

this.http.get<User>('/api/user').subscribe({
  next: (res: HttpResponse<User>) => console.log(res.body),
  error: (err: HttpErrorResponse) => console.error(err.statusText)
});
							

6. Signal Forms — Future of Angular Forms

Angular 21 introduces Signal Forms, a signals-based replacement for both Template Forms and Reactive Forms.

const form = signalForm({
  name: control(''),
  age: control(0)
});
							

7. New UI Library: Angular ARIA

Angular introduces Angular ARIA, a modern UI foundation library with built-in accessibility.

<aria-dialog>
  <h3>Confirmation</h3>
  <button aria-dialog-close>Close</button>
</aria-dialog>
							

8. SimpleChanges Now Supports Generics

SimpleChanges becomes generic, making ngOnChanges type-safe and preventing mistakes with input names or value types.

ngOnChanges(changes: SimpleChanges<{ count: number }>) {
  console.log(changes.count.currentValue);
}
							

9. Signal API Enhancements

Signals continue to evolve, making them even more powerful.

const profile = computedAsync(async () => {
  return await fetch('/api/profile').then(r => r.json());
});
							

10. Zoneless Change Detection Fully Stabilized

One of Angular’s biggest milestones: running without Zone.js is now fully stable and ready for production apps.

bootstrapApplication(AppComponent, {
  experimentalZonelessChangeDetection: true
});
							

11. SSR + View Transitions for Smooth Navigation

Angular 21 improves SSR by enabling native View Transitions.

<div viewTransition>
  <router-outlet></router-outlet>
</div>
							

12. Optimized Image Component

The <ng-img> directive gets smarter and faster.

This directly boosts Core Web Vitals like LCP & CLS.

13. CLI & Build Performance Upgrades

Angular 21 upgrades ESBuild handling and improves incremental rebuild speed.

Conclusion

Angular 21 is not just another incremental update. It strengthens the framework in the areas developers care about most: performance, simplicity, accessibility, and modern developer experience.

From Signal Forms to the new Angular ARIA library, better HttpClient defaults, zoneless stabilization, and upgraded schematics—Angular 21 pushes the ecosystem closer to a lightweight, future-ready architecture.
