Difference Between forRoot and forChild method

forRoot method

The forRoot method is used in the root module (typically app.module.ts) of the Angular application to configure services, routes, and other settings that are shared across the entire application. It is responsible for providing services and configuring routes globally. This method is only called once in the root module....

forChild Method

The forChild method is used in feature modules to configure routes and other settings that are specific to that module. It allows feature modules to contribute their own routes without interfering with the global configuration set up by forRoot....

Conclusion:

In Angular, forRoot and forChild are two methods used to configure routing and other settings at different levels within an application. forRoot is used in the root module to set up global configurations, while forChild is used in feature modules to configure module-specific settings, such as routes. Understanding the differences between these methods is crucial for structuring and configuring Angular applications effectively....
