🚀 Angular v20 is Officially Released!
Angular v20 is now available as of May 29, 2025, introducing major updates focused on performance, developer experience, and modern web practices.
✅ Stabilizing APIs
The reactive programming model is now stable with production-ready APIs like effect(), linkedSignal(), and toSignal().
import { signal, effect } from '@angular/core';
const counter = signal(0);
effect(() => {
console.log('Counter changed to:', counter());
});
counter.set(1); // Logs: Counter changed to: 1
counter.update(c => c + 1); // Logs: Counter changed to: 2
⚡ Zoneless Change Detection (Developer Preview)
Angular v20 introduces a preview of zoneless change detection, improving performance and simplifying debugging.
import { provideExperimentalZonelessChangeDetection } from '@angular/core';
bootstrapApplication(AppComponent, {
providers: [provideExperimentalZonelessChangeDetection()],
});
🌐 Enhanced Server-Side Rendering (SSR)
Features like incremental hydration and route-level rendering are now stable.
export const routes: Routes = [
{
path: 'products',
loadComponent: () => import('./products.component').then(m => m.ProductsComponent),
data: { ssrRender: true }, // Render this route server-side
}
];
🛠️ Chrome DevTools Integration
Angular-specific profiling data is now available directly in Chrome DevTools’ Performance tab. Includes:
- Component lifecycle timings
- Change detection events
- Template rendering phases
No extra setup—works automatically in development mode.
🧹 Updated Style Guide and Naming Conventions
Angular CLI no longer adds suffixes to file names by default.
# Before (Angular v19)
ng generate component user
# Generates: user.component.ts
# After (Angular v20)
ng generate component user
# Generates: user.ts (no .component suffix)
You can override with:
ng generate component user --style-guide-compat=false🧪 Extended Type Checking in Host Bindings
Improved type safety and support for host bindings and listeners.
@Directive({
selector: '[appHighlight]',
host: {
'[class.highlighted]': 'isHighlighted' // Type-checked
}
})
export class HighlightDirective {
isHighlighted = true;
}
