Angular Best Practices For A Clean And Robust Angular Application

Angular known as an open-source platform for web application development. With covering the limitation of all frameworks, angular increase the performance and speed of web applications. Here in this article, we are going to discuss the Angular best practices for a clean and robust angular application. If you want to increase the performance and speed of your application, then you must need to follow these angular best practices.

1) trackBy

Normally, developers use ngFor to loop over an array in templates, Instant of that if you will use TrackBy, it will give a different identity to all the components.

Sometimes due to any reason if array changes, Angular re-renders the full process of DOM. but if you used trackby in your application, angular will able to identify which element has changed and will only work on those changes.

2) Lazy load When possible, try to use lazy load the modules in the web application. Lazy loading work is to load something when it is used. for example, loading a component only when it’s required to be seen. By doing this you can maintain the low size of the application, so it will take less time to load and can improve the performance of the application by not loading those components which are not required to be seen.

3) Avoid any; type everything

You must need to declare variables with a type other than any.

If you will not declare variables in Typescript without typing, at that time value of that variable will be deduced and its cause unintended issues.

4) Components should only deal with display logic

You must need to avoid any kind of logic, whenever you are going to make a component. You only need to deal with display logic.

This is one of the best angular practices in 2021 to improve the performance and security standard of your application.

Another way of increase the performance of your application is maintaining the standard of your coding, getting to know more about coding standards, how it will help you and an in-depth understanding of angular modules best practices will make sure the performance and security of your web application.
