Angular v20 Developer Event 2025

Introduction

Welcome to the Angular v20 Developer Event tutorial. In this guide, we will explore the exciting new features introduced in Angular v20, focusing on performance improvements, enhanced security, and upgraded tooling. Whether you are a seasoned developer or just getting started, this tutorial will help you understand the latest enhancements and how to implement them in your projects.

Step 1: Explore Performance Improvements

Angular v20 brings significant performance enhancements that can optimize your applications.

• Lazy Loading:

  • Ensure modules are loaded only when required, reducing initial load times.
  • Use Angular's built-in lazy loading feature by defining routes in your app-routing.module.ts:

    const routes: Routes = [
      { path: 'feature', loadChildren: () => import('./feature/feature.module').then(m => m.FeatureModule) }
    ];
    

• Change Detection Strategy:

  • Adopt the OnPush change detection strategy to improve performance by minimizing checks on components that do not frequently change.

• TrackBy Function:

  • Use the trackBy function in ngFor loops to help Angular track items in lists efficiently:

    <div *ngFor="let item of items; trackBy: trackByFn">
      {{ item.name }}
    </div>
    

Step 2: Implement Security Enhancements

Security is paramount in web applications, and Angular v20 has introduced several key features to bolster security.

• Enhanced Sanitization:

  • Angular provides built-in sanitization for HTML and URL data to protect against XSS attacks. Make sure to use Angular's built-in sanitization services whenever possible.

• Strict Template Type Checking:

  • Enable strict template type checking in your application’s tsconfig.json to catch potential security issues early in the development process.

    {
      "angularCompilerOptions": {
        "strictTemplates": true
      }
    }
    

Step 3: Utilize Improved Tooling

Angular v20 includes several upgrades to tools that enhance the development experience.

• Updated CLI Features:

  • Take advantage of new commands in the Angular CLI to streamline your workflow. Run ng update to upgrade dependencies smoothly.

• Better Debugging Tools:

  • Use the improved debugging tools in Angular DevTools for a more efficient way to diagnose and fix issues in your applications.

• Integration with Popular IDEs:

  • Leverage support for popular IDEs that provide Angular-specific tools and plugins to enhance your coding experience.
