Customizing Angular-Runtime modification of Web Apps with Module Federation

Module Federation is a feature in Angular that allows for modifying and customizing the runtime of web applications. It allows developers to split a monolithic application into smaller, independent modules that can be developed and deployed separately. This provides a number of benefits, including increased scalability, improved maintainability, and faster development times.

In this article, we will go through the steps to customize an Angular application using Module Federation. To follow along, you will need to have a basic understanding of Angular and its architecture.

Step 1: Set up the main application

To begin, we need to set up the main application that will host the federated modules. In this example, we'll call it the "shell" application. The shell application should have its own set of dependencies and a default routing configuration.

Step 2: Create the federated modules

Next, we will create the federated modules that will be added to the main application. Each module should have its own set of dependencies and a unique routing configuration.

Step 3: Configure the federated modules

To configure the federated modules, we need to add a "remotes" property to the shell application's angular.json file. This property should include the name and location of each federated module.

Step 4: Update the main application's routing configuration

Once the federated modules have been added to the shell application, we need to update the main application's routing configuration to include the routes from each module. This can be done by using the Angular Router's lazy-loading feature.

Step 5: Deploy the application

Finally, we can deploy the application and test it to see if everything is working as expected.

In conclusion, customizing the runtime of an Angular application using Module Federation provides a number of benefits, including increased scalability, improved maintainability, and faster development times. By following these steps, you can get started with customizing your own Angular application using Module Federation.
