To build truly native applications, the Angular framework is used globally. The interactive tools offered by Angular outpasses the other competing frameworks. In a generic scenario, Developers usually seek the advanced features so badly they typically forget about the standard Angular best practices, which is the classic formula of neat and dynamic outcomes!

Before starting coding for anything, you have to go through these best practices at least once to get better outcomes!

Make Use of trackBy

When you want to create templates for each item of the collection, a built-in Angular directive – ngFor is used. The main issue with ngFor is when we need to change the data, it is not viable for Angular as it does not record when the data is entered or removed. To avoid these complications, the feature 'trackBy' comes in handy.

Avoid mixing the Use of Logic in the Component.

It is a pretty common mistake that every other developer makes at the time of development. They usually mix up the component and business logic together when it has been recorded separately. It increases the code review, readability, neatness of the code, and high-scale application performance.

Prevent Memory Leaks

Memory leaks are pretty observable in almost every framework. However, with Angular, it can be preventable. These memory leaks are quite dangerous as it plays with the application's security to make this leak stop with Angular. The user can utilize the async pipe and Take as an operator.

*Use of Lazy Loading *

This feature is an in-built feature of Javascript, which automates the performance and productivity of the application. To enhance the speed of the application, it divides the application into various bundles.

Declaring Variable Types Rather Than Using any

Several developers put 'any' as a variable. This is a huge mistake! This will lead to minor bugs, and it will be tough to debug them as Angular reads this as a variable's type based on that particular variable's value. Instead of that, you can use numbers in the place of any.

Angular Coding Practices and Angular Project Structure

Developers tend to forget about the standard coding practices in the way of finding the advanced techniques. These practices are utterly not advisable. Applying traditional methods increases the efficiency, readability, and authenticity of the application.

Angular State Management Best practice: Utilize Central State Management (Redux/Ngrx)

When working with a small or medium-sized application, state management is manageable; however, it gets complex and hectic when its size increases. To implement smooth communication between the components, it is advisable to follow Angular State Management.

To conclude, this is all about the angular code checklist. It not only improves your code but also strengthens it. This checklist should always be in your mind before starting to develop. Best applications happen when the developer very well knows angular modules best practices and what to code and what not to!
