1. Enhanced Signals and Reactive Composition
What’s New in Angular 18?
-
Full Integration of Signals: Signals are now a core part of Angular’s reactive programming model.
-
Improved Change Detection: Signals allow more granular updates, which means only the parts of the app that need to change are updated.
- Reactive Composition APIs: Developers can now combine Signals with Observables (used in RxJS) for a smoother development experience.
Why It’s Important
-
State updates become predictable and easier to manage.
-
Debugging reactive states is less complicated.
- Existing RxJS workflows can be used with Signals, so you don’t need to change everything in your app.
Example Code
import { signal, computed } from '@angular/core';
const count = signal(0);
const doubled = computed(() => count() * 2);
function increment() {
count.set(count() + 1);
}
2. Built-in Tailwind CSS Support
Key Benefits
-
Quick setup with a single command.
-
Faster and easier styling of your applications.
- There is no need for extra configuration files.
How to Enable Tailwind CSS
Run the following command in your project:
ng add @angular/tailwind
3. Advanced Server-Side Rendering (SSR) with Streaming
What’s New in Angular 18?
-
Streaming SSR: You can now render parts of the page while other parts are still loading, which improves the user experience.
-
Partial Hydration: Only the necessary JavaScript code is executed on the client side, reducing load times.
Benefits
-
Faster Time-to-Interactive (TTI).
-
Improved app performance and SEO.
4. Component-First Routing Refinements
Features
-
Define nested and lazy-loaded routes within components.
-
Simplified configuration for routing in modular apps.
Example Code
@Component({
standalone: true,
template: `<router-outlet></router-outlet>`,
})
export class AdminComponent {}
const routes = [
{ path: 'admin', component: AdminComponent, children: [
{ path: 'settings', component: SettingsComponent },
] },
];
5. Improved TypeScript Support
-
Faster build times and type-checking.
-
Support for new TypeScript features like decorators.
- Better control over null checks to avoid errors.
6. Dynamic Theme Switching
Features
-
Built-in Theme Service to manage themes.
-
CSS Variables for flexible and maintainable themes.
Example Code
import { ThemeService } from '@angular/core';
const themeService = new ThemeService();
themeService.setTheme('dark');
7. Improved Testing Tools
-
Mocked Signals for reactive state testing.
-
Improved Component Harness for intuitive interactions during testing.
8. Smaller Bundle Sizes with ESBuild Optimizations
-
Faster load times for users.
-
Less bandwidth usage.
9. Updated Angular Material Components
-
New components based on Material Design 3 (M3).
-
Improved theming options to work with the Dynamic Theme API.
- More responsive and accessible components.
10. Enhanced Debugging with Angular DevTools
-
Visualization of Signals and their dependencies.
-
Improved error tracking for SSR and lazy-loaded routes.
Why Should You Upgrade to Angular 18?
-
Better Performance: Optimizations like SSR streaming and smaller bundles make apps faster.
-
Improved Developer Experience: Features like Signals, Component-First Routing, and Tailwind CSS support simplify development.
- Modern Features: New TypeScript support, dynamic themes, and updated Angular Material components keep your app up-to-date with modern web standards.
How to Upgrade
To upgrade your existing Angular project, run this command:
ng update @angular/core @angular/cli
