When it comes to delivering exceptional applications, mastering Angular development is crucial. Here are 10 essential Angular development tips that will elevate your coding skills:

1. Understand Angular Fundamentals: Before diving deep, ensure you have a solid grasp of the core concepts such as components, services, and modules.
2. Utilize Angular CLI: The Angular Command Line Interface streamlines your workflow, allowing you to create new projects, components, and services with ease.

Additionally, adopting best practices can significantly improve your development efficiency. Remember to:

• Implement Lazy Loading: Optimize your application’s performance by using lazy loading for feature modules, which reduces initial load time.
• Leverage Dependency Injection: This powerful feature promotes clean code and effective testing by allowing you to manage service instances.

When developing with Angular, one of the common mistakes to avoid is neglecting the importance of proper component architecture. Many developers tend to create large, monolithic components instead of breaking them down into smaller, reusable pieces. This can lead to challenges in maintainability and testing. To improve your application's structure, consider following the Angular Style Guide, which emphasizes the use of smart and dumb components. Smart components handle business logic, while dumb components focus purely on presentation.

Another pitfall in Angular development is failing to optimize performance. Developers often overlook the usage of ChangeDetectionStrategy and OnPush change detection strategies, which can significantly enhance app performance. Additionally, be cautious with the use of excessive watchers - keep an eye on your application's performance metrics and utilize tools like Angular Profiler to identify potential bottlenecks. Implementing asynchronous loading and lazy loading modules can also help in minimizing initial load times.

Boosting your Angular performance is essential for creating efficient, user-friendly applications. One of the best practices is to utilize Change Detection Strategy. By setting your components to use the OnPush change detection, Angular will only check the component when its input properties change or an event occurs, resulting in fewer checks and faster rendering. Additionally, consider using the trackBy function in your *ngFor loops, which allows Angular to track the items and only update the ones that have changed, significantly improving performance on long lists.

Another effective strategy is to minimize the size of your bundles. Use the Angular CLI to enable tree-shaking and lazy loading, which will load modules only when needed. This helps decrease the initial load time of your application. Lastly, employ performance profiling tools like Angular DevTools to identify bottlenecks in your application. Regularly profiling your app will ensure that you are aware of performance issues and can address them promptly.
