Top 10 Angular Best Practices to Improve Your Angular App Performance

Angular is an incredible JavaScript framework that has helped many developers create robust and interactive web applications. However, like any language, there are certain best practices you should follow to ensure maximum performance from your Angular app.

Here are some of the Top 10 Angular best practices to improve your Angular app performance:

1. Use Performance Tools for Measuring and Understanding Bottlenecks

When developing an Angular application, it’s important to understand how to use performance tools such as Chrome DevTools and the Angular CLI. These tools will help you identify potential bottlenecks and take corrective action accordingly.

2. Improve the Code Quality of Your Application

Writing high quality code is key to having a solid Angular application. One way to ensure good code quality is by utilizing TypeScript to type-check your code as well as using linters to keep your code clean and compliant.

3. Utilize the Angular Compiler for Incremental Builds and Fast Rendering

The Angular compiler allows developers to make incremental builds in order to reduce the build times. This in turn increases the speed with which Angular apps render. It also helps to reduce the size of the application when deployed.

4. Reduce Load Times By Minifying Your Code

Minification is the process of removing unnecessary characters from your source code without altering its functionality. This reduces the size of your code and consequently reduces your application's loading time.

5. Lazy Loading Modules for Optimizing Performance

Lazy loading is a design approach where modules and components are loaded on demand instead of during the initial page load. This can significantly reduce the overall size of your application, while providing a snappier performance for the end user.

6. Use Built-In Angular Caching Strategies

Angular provides various built-in caching strategies which can be utilized to improve the performance of your application. This includes memory caching, disk caching, and HTTP caching, all of which allow for faster data retrieval times.

7. Optimize NgModules for Improved Efficiency

Using NgModules is an efficient way of organizing the codebase for your application. Optimizing NgModules can help streamline the development process and improve the overall performance of your Angular app.

8. Use Change Detection Strategies to Boost Performance

Change detection is a critical component of an Angular application. Utilizing proper change detection strategies can improve the performance of your application by reducing the amount of unnecessary computation.

9. Utilize Ahead-of-Time Compilation for Faster Rendering

Ahead-of-Time compilation (AOT) compiles your application at build time, so your application can run faster at runtime. This is especially beneficial for web applications with complex logic or multiple components.

10. Use Client-Side State Management Libraries

State management libraries like Redux can be used to manage the application state and ensure that data is passed around efficiently. Using these libraries can help improve the performance of your Angular application.
