Today, in this article, we will discuss the most significant features of Angular Framework i.e. Feature Modules.

Today, in this article, we will discuss the most significant features of Angular Framework i.e. Feature Modules. With the help of Angular Framework, we can develop both large-scale based application or small scale based application. Actually, with the help of Angular Modules, we can be designed our application into a part of different modules so that we can manage the application in a much better way. Since, if we use one single block or module for our application, then when the application starts growing to incorporate the new features and functionalities, it becomes a tedious job to manage the entire mode under a single block or module. In the same place, if we use multiple modules or blocks, then the maintenance of the code is easier. In this way, we can incorporate the new functionality or features in a new module and then include that module in our application.

So, there are many possible ways to group the functionalities into modules and the decision always depends upon the developers to find the best way for the application. So, when we break the application into multiple modules, then it becomes one of the important responsibilities of developers to maintains all modules so that performance of the application can be boosted up. We can break the application into multiple modules and then import all modules references into the bootstrapped module. The result of this approach will be that application loading will be slow as the application size increases. So, the best approach is that break the application into multiple modules as a Feature Module which can provide the following benefits –

  1. It will avoid the loading of the entire application at a time.
  2. Can be pre-loaded the features modules in the background
  3. Lazy load of the feature modules on demand means when the user wants to access that module or related functionality then only that particular module will be loaded into the DOM.

So, in this article, we will discuss the concept of Feature Modules and the Lazy loading of a Feature Module and also demonstrate how to implement this concept into any Angular Application.

What Is Feature Modules in Angular?

So, in Angular Framework, Feature Module is simply an Angular module with module related kinds of stuff and purpose. But the main difference is that is not the root module of the application. Feature module is just an additional typescript based class with the @NgModule decorator and registered metadata. Feature modules isolate the applications based on the functionality or business operation and it collaborates with the root modules or any other feature modules.

The main purpose of the feature modules is to break down the functionality which focuses on any particular internal business operation or functionality that needs to be dedicated as a module so that we can achieve modularity in the application. With the help of feature modules, we also can restrict the responsibility of the root modules and help the root module to keep it thin and small.
