Understanding the Angular CLI Command to Generate a New Module

Angular is a powerful Javascript framework used for building dynamic web applications. Leveraging Angular involves understanding and correctly implementing various Command Line Interface (CLI) commands. One such important CLI command is ng generate module.

When building an Angular application, you may often find yourself requiring new modules. The Angular CLI provides an efficient way to generate these new modules with a single command, ng generate module, sometimes shortened to ng g m.

Practical Application of 'ng generate module'

If you wanted to generate a new module called 'user', you would run the following command in your terminal:

ng generate module user

This command tells Angular to create a new module named 'user', and it creates a directory with the same name, which contains the module file. Furthermore, this command automatically updates the app module to include the user module.

Best Practices and Additional Insights

While creating modules, it can be helpful to generate them in their respective folders for better organization of your application. For instance, to generate a module called 'profile' inside the 'user' module, you would run:

ng generate module user/profile

Another useful tip is to include a routing file while generating your module using -–routing. This is particularly useful if your module contains several components:

ng generate module user/profile –-routing

This generates an additional 'profile-routing.module.ts' file.

It's important to remember that Angular modules help to keep code organized, reusable, and provide the ability to load pieces of the application on demand. Therefore, understanding how to generate modules using Angular CLI is crucial for efficient Angular development.
