Angular 20 Is Here: Master the Latest Features Like a Pro 🚀

Angular 20 has landed, and it solidifies Angular’s transition into a fully modern, reactive, and standalone-first framework. With huge improvements in developer ergonomics, performance, and reactivity, this release pushes Angular into a whole new league.

In this article, we’ll break down what’s new in Angular 20, why it matters, and how to use it — with expert insights and code snippets to back it up.

Key Features in Angular 20

🔹 1. Built-in Control Flow Syntax (Stable)

Angular 20 finalizes the new syntax: @if, @for, @switch, and @defer.

@for (let item of items; track item.id) {
  <li>{{ '{{' }} item.name {{ '}}' }}</li>
} @empty {
  <p>No items available.</p>
}

✅ No more structural directive boilerplate (*ngIf, *ngFor)

✅ Better readability and tooling

✅ Supports @empty, @else, @placeholder, and @loading blocks

🔹 2. Signals Are Now Officially Core

After several versions in preview, Signals are now a core part of Angular’s reactivity model.

Why it matters:

• No subscriptions
• Auto-updating views
• Declarative state and derived values

Three key APIs:

signal();     // Writable signal
computed();   // Derived read-only signal
effect();     // React to signal changes

🔹 3. Enhanced View Transitions API (Router-level)

{
  path: 'pokemon',
  loadComponent: () => import('./pokemon.component'),
  data: { animation: 'fade' }
}

🔁 Enables animations between route navigations using the Web Animations API and Angular’s declarative configuration.

🔹 4. Required Inputs with input.required()

import { input } from '@angular/core';

@Input() item = input.required<Item>();

💥 Compile-time safety for missing inputs

💡 Works perfectly with standalone components

🔹 5. @defer & Partial Hydration (Experimental)

Use @defer blocks for on-demand component rendering — ideal for improving performance in SSR and CSR apps.

@defer (when visible())
  <lazy-component />
@placeholder
  <p>Loading...</p>

🔹 6. Deferrable Views + Built-in Placeholders

Combine lazy component rendering with built-in support for @loading and @placeholder.

🔹 7. Standalone First: NgModules Are Fully Optional

Angular 20 fully embraces the standalone component-first approach.

@Component({
  standalone: true,
  selector: 'my-feature',
  template: `...`,
  imports: [CommonModule, FormsModule],
})

🧼 Cleaner APIs

🪶 Lighter mental model

🚀 Faster learning curve for new devs

Advanced Example: Defer + Control Flow + Signals

@Component({
  standalone: true,
  template: `
    <h2>📊 Popular Pokémons</h2>
    @defer (when loaded())
      @for (let p of pokemons())
        <p>{{ '{{' }} p.name {{ '}}' }}</p>
      @placeholder
        <span>Loading Pokémons...</span>
    @loading
      <spinner />
  `,
})
export class PokemonList {
  pokemons = signal<Pokemon[]>([]);
  loaded = signal(false);

  constructor(private api: PokemonService) {
    effect(() => {
      this.api.getAll().then(data => {
        this.pokemons.set(data);
        this.loaded.set(true);
      });
    });
  }
}
