Understanding Lazy-Loaded Feature Module Generation in Angular

Angular provides a powerful feature to generate a new lazy-loaded feature module using the Angular CLI (Command Line Interface). The correctness of the statement outlined in the quiz is confirmed: the command to generate a new lazy-loaded feature module in Angular is indeed ng generate module <module-name> --route <route-name> --module <parent-module>.

Firstly, let us understand what a lazy-loaded feature module is. In Angular, this concept is used to only load the application features that a user actually needs to interact with, which enhances application efficiency, particularly when the app is large with numerous features.

The syntax of the command might seem complex, so let's break it down:

• ng generate module : This is the standard command to generate a new module in Angular. <module-name> represents the name you want to give to your new module.

• --route : This flag adds routing to the new module. <route-name> is a placeholder for the name of the route you want to create.

• --module : This flag attaches the newly created module and routing to the specified parent module. <parent-module> is the placeholder for the parent module name.

For example, if you want to create a new module named products, with a route named allproducts under the app module, you would run the following command:

ng generate module products --route allproducts --module app.module

This command will create a new lazy-loaded feature module named products, complete with its own routing configured under the allproducts path in your application.

One of the best practices when using Angular is to heavily utilize its feature module concept. By dividing your application into logical blocks of functionality (i.e., feature modules), your product becomes more organized, more maintainable, and more scalable.

Creating feature modules on-the-fly with Angular CLI, and using Angular's lazy loading features, reduce initial load times and speed up the application. This results in an improved user experience, something always worth striving for in web development.

To summarize, Angular's ng generate module command is a powerful tool for creating new lazy-loaded feature modules, improving both your workflow and the end-user experience.
