🚀 Angular 20 Features & What’s New in 2025 (With Examples)

[ROHIT SINGH]

Angular continues to evolve as one of the most popular front-end frameworks, and with Angular 20, the team has introduced powerful new features, performance upgrades, and developer experience improvements.

If you’re wondering what’s new in Angular 20 and why you should upgrade, this guide will walk you through the top features, examples, and migration tips.

1. Stable Angular Signals

Angular Signals, introduced experimentally in Angular 16, have now reached full stability in Angular 20.

Reactive state management without RxJS boilerplate.

Easy-to-read code for managing app state.

Better performance since change detection is more granular.

Example – Counter App with Signals:

import { Component, signal } from '@angular/core';

@Component({
  selector: 'app-counter',
  template: `
    <h2>Count: {{ count() }}</h2>
    <button (click)="increment()">Increment</button>
  `
})
export class CounterComponent {
  count = signal(0);

  increment() {
    this.count.update(value => value + 1);
  }
}

No need for BehaviorSubject or NgRx for simple cases. Signals make Angular apps more reactive and predictable.

2. Standalone APIs Everywhere

With Angular 20, standalone APIs are the default way to build Angular apps.

No need for NgModule anymore.

Components, directives, and pipes can be used standalone.

Faster bootstrapping with less boilerplate.

Example – Bootstrapping a Standalone App:

import { bootstrapApplication } from '@angular/platform-browser';
import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  standalone: true,
  template: `<h1>Hello Angular 20 🚀</h1>`,
})
export class AppComponent {}

bootstrapApplication(AppComponent);

This reduces complexity and makes Angular feel more like React or Vue.

3. Stronger TypeScript Support

Angular 20 now supports TypeScript 5.5+, which means:

Better type inference.

Decorator enhancements.

Faster compilation.

Example – Safer Type Inference:

let username = 'Anshul';
username = 123; // ❌ TypeScript 5.5 will catch this instantly

Stronger typing = fewer bugs in production.

4. Built-in ESBuild Support

Angular CLI now uses ESBuild to make builds faster and bundles smaller.

Up to 3x faster build times.

Reduced bundle sizes for production.

Improved hot module replacement (HMR).

Example – Production Build Command:

ng build --configuration production

Thanks to ESBuild, the build will be lighter, faster, and optimized by default.

5. Improved Server-Side Rendering (SSR)

Angular 20 has major improvements for Angular Universal:

Faster hydration (seamless handoff from server to client).

Automatic prefetching of lazy routes.

New CLI commands for easy setup.

Example – Hydration Enabled in App Config:

import { provideClientHydration } from '@angular/platform-browser';

bootstrapApplication(AppComponent, {
  providers: [provideClientHydration()]
});

This boosts SEO and Time-to-Interactive (TTI), making Angular apps more competitive.

6. Angular Material v20

Angular Material has been updated with:

Material You (M3) design system.

Dynamic theming and improved accessibility.

Example – Material You Button:

<button mat-flat-button color="primary">Primary Button</button>
<button mat-flat-button color="accent">Accent Button</button>
<button mat-flat-button color="warn">Warn Button</button>

Components now follow modern design guidelines automatically.

7. Security Enhancements

Angular 20 adds security-first defaults:

Trusted Types for XSS protection.

Content Security Policy (CSP) integration.

Example – Preventing Unsafe HTML:

import { DomSanitizer } from '@angular/platform-browser';

safeHtml(html: string) {
  return this.sanitizer.bypassSecurityTrustHtml(html);
}

Built-in safeguards reduce common security risks.

8. Better Debugging & DevTools

Angular DevTools now provides:

Signals monitoring.

Change detection tracking.

Performance profiling.

Developers can now see exactly what triggered re-renders.

Should You Upgrade to Angular 20?

Yes, definitely! Angular 20 brings:

Faster builds (ESBuild).

Modern state management (Signals).

Cleaner architecture (Standalone APIs).

Stronger security and SSR support.

Upgrade Command:

ng update @angular/core@20 @angular/cli@20

Final Thoughts

Angular 20 marks a big leap forward for developers by combining simplicity, performance, and scalability.

Whether you’re building small apps or enterprise-grade platforms, Angular 20 makes development faster, safer, and more future-ready.
