Angular has been evolving rapidly, and with Angular 20, the framework continues its shift toward performance, developer experience, and reactivity. If you’ve been following the journey since Angular 16 (Signals, Standalone Components, Hydration), this release builds on that foundation with exciting improvements.
Let’s dive into the key features of Angular 20.
1. Smarter Signals Enhancements
Signals, first introduced in Angular 16, are now more powerful in Angular 20.
- Improved APIs for Computed Signals – making complex reactive flows easier.
- Better Debugging – Angular DevTools now helps visualize signal dependencies.
- Deeper RxJS Integration – bridging traditional reactive streams with signal-based state.
import { signal, computed } from '@angular/core';
const count = signal(0);
const double = computed(() => count() * 2);
count.set(5);
console.log(double()); // 10
2. Faster SSR & Partial Hydration
Server-Side Rendering (SSR) continues to improve:
- Partial Hydration → Only rehydrates parts of the page that need interactivity.
- Reduced JavaScript Payloads → Smaller bundle sizes mean faster page loads.
- Improved Time-to-Interactive (TTI) for SEO-driven apps.
3. Standalone Components First
Angular 20 doubles down on the standalone-first approach:
- Better tooling support in Angular CLI for generating standalone apps.
- Simplified bootstrapping — modules are optional in most cases.
- Cleaner, more lightweight architecture for greenfield projects.
import { Component } from '@angular/core';
@Component({
selector: 'app-hello',
standalone: true,
template: `<h1>Hello Angular 20 🚀</h1>`
})
export class HelloComponent {}
4. Compiler & Performance Boosts
Angular 20 introduces several under-the-hood improvements:
- Smarter tree-shaking → smaller bundles.
- Optimized build pipeline with ESBuild/Vite integration.
- Faster rebuilds → significant boost for local dev workflows.
5. TypeScript 5.x Support
Angular 20 now fully supports TypeScript 5.x, bringing:
- Better type inference.
- Decorator enhancements.
- Future-proofing Angular projects with the latest TS features.
6. Tooling & Ecosystem Updates
- Angular DevTools → New panels for inspecting signals & reactivity.
- CLI improvements → Faster scaffolding, stricter defaults.
- Easier integration with modern build tools like Vite.
Conclusion
Angular 20 is a big leap forward in making apps:
- Faster (SSR + hydration + compiler optimizations)
- Simpler (standalone-first architecture)
- More reactive (powerful Signals with RxJS bridging)
If you’re building Angular apps in 2025, it’s time to explore Signals + Standalone Components and harness Angular 20’s performance boosts.
