Angular 21: Direction and Thinking Behind the Framework
-
High performance, so apps run fast even with many users
-
Signal-based reactivity for a clear and predictable state
- Standalone and modular structure for clean code
- Enterprise-level stability for long-term projects
-
Better developer experience so teams can work faster and happier
1. Signals: The New Base for State in Angular
What Are Signals?
Why Signals Are Important
-
Data changes are clear and predictable
-
Only the needed parts of the UI update
- Apps become faster
- Debugging becomes easier
-
Less code is required
Example Using Signals
import { signal, computed } from '@angular/core';
export class ProductComponent {
quantity = signal(1);
price = signal(1200);
total = computed(() => this.quantity() * this.price());
increment() {
this.quantity.update(q => q + 1);
}
}In this example:
-
quantityandpriceare simple signals -
totalupdates automatically when either value changes - No manual change detection is needed
Sparkle Web View
-
We use signals for UI and component-level state
-
We still use RxJS for APIs, streams, and async work
2. State Management in Angular 21
A Simpler Way to Manage State
Recommended State Tools (2026)
NgRx Signal Store: The New Direction
-
The structure of NgRx
-
The simplicity of signals
export const CartStore = signalStore(
withState({ items: 0 }),
withMethods(store => ({
addItem() {
store.items.update(v => v + 1);
}
}))
);This approach:
-
Reduces boilerplate
-
Makes apps faster
- Keeps enterprise-level structure
3. Standalone Components Are the Default
Why Standalone Components Are Better
-
Less setup code
-
Easier to understand
- Faster builds
- Better lazy loading
-
Faster onboarding for new developers
Example
@Component({
standalone: true,
selector: 'app-dashboard',
imports: [CommonModule],
templateUrl: './dashboard.html'
})
export class DashboardComponent {}Enterprise Impact
-
All new Angular projects use a standalone-first architecture
-
This helps apps scale without becoming messy
4. Better Template Control Flow
Example
@if (orders.length > 0) {
@for (order of orders; track order.id) {
<p>{{ order.name }}</p>
}
} @else {
<p>No orders available</p>
}Benefits
-
Templates are easier to read
-
Fewer errors at runtime
- Better checks during build
- Cleaner HTML
5. Zoneless Angular: Faster Change Detection
Why Removing Zone.js Helps
-
Smaller app size
-
Better performance
- Clear control over updates
- More predictable behavior
Example Setup
bootstrapApplication(AppComponent, {
providers: [
provideExperimentalZonelessChangeDetection()
]
});When using Zoneless Angular
