Angular 19 is another big release in the Angular journey. It comes with lots of new features and performance improvements to make development easier and application faster.
Features and Improvements in Angular 19
1. Server-Side Rendering (SSR)
Faster First Page Load: Angular 19 optimizes SSR even more, so first page load is much faster. This is important for SEO and user experience especially for big and complex applications.
Faster Hydration: The hydration process where the static HTML rendered on the server is converted to a fully interactive Angular application on the client-side is more efficient.
2. Ivy Compiler
Smaller Bundles: Ivy compiler is getting even smaller. Faster load times and less bandwidth usage.
Template Compilation Optimization: Compiler is optimized for better build times and runtime performance.
3. Experimental Features
Standalone Components: This experimental feature allows you to create components that are not part of NgModules. This can simplify application architecture and reduce boilerplate code.
Directive Composition API: This experimental feature allows you to create custom directives in a more flexible and concise way.
Upgrade to Angular 19
Upgrading to Angular 19 is easy. Use the Angular CLI to update your project:
Bash
ng update @angular/core @angular/cli
Use with caution.
Note: Please check the official Angular documentation and migration guide for more information and breaking changes.
Angular 19 Best Practices
To get the most out of Angular 19:
Use Lazy Loading: Break your application into smaller, lazy loaded modules to improve first load and overall performance.
Optimize Images: Compress images and use the right format (e.g. WebP) to reduce file size and load time.
Minimize HTTP Requests: Combine and minify CSS and JavaScript files, use service worker to cache static assets.
Monitor: Use Angular DevTools to find performance bottlenecks and optimize.
