🚀 Optimizing Angular Performance: Best Practices 🚀

As an Angular enthusiast, I’ve honed my skills by building robust applications. Today, I’m excited to share essential best practices for boosting Angular app performance. Whether you’re a seasoned developer or just starting, these tips will help you create faster, smoother experiences for your users.

1. Change Detection Strategy: OnPush

Angular’s default change detection can be resource-intensive. By using the OnPush strategy, we can significantly improve performance:

• Set changeDetection: ChangeDetectionStrategy.OnPush in your component.

• Angular checks for changes only when input properties change, reducing unnecessary re-renders.

Example:

TypeScript

2. Lazy Loading Modules

Optimize initial load times and reduce bundle size by loading modules lazily:

• Define feature modules (e.g., user module, admin module).

• Use the property in your route configuration.

Example:

TypeScript

3. Optimize Rendering

• ngIf and ngFor: Use them judiciously. Avoid excessive use. Consider using for conditional rendering.

• trackBy: Provide a function when rendering lists with to optimize list updates.

Example:

HTML

4. Preloading Modules

Enhance the user experience by preloading critical modules in the background:

• Use Angular’s strategy.

Example (in your ):

TypeScript

5. Optimize Third-Party Libraries

• Be cautious with heavy third-party libraries. Include only what you truly need.

• Consider tree-shaking to remove unused code from bundles.

Remember, performance optimization is an ongoing journey. Regularly profile your app, analyze bottlenecks, and fine-tune it accordingly. Let’s create blazing-fast Angular apps together! 🚀
