How can Angular be used to implement Microfrontend with Server-Side Rendering (SSR)?

edit

Angular can be used to implement microfrontends with server-side rendering (SSR) by using the technique of lazy loading. In this approach, each microfrontend is developed as a separate Angular application and is loaded asynchronously on the client-side as needed.

To implement SSR, Angular provides the Angular Universal module that allows the application to be rendered on the server-side. This module can be used to render each microfrontend separately and stitch them together at runtime.

The steps to implement microfrontends with SSR are as follows:

1. Develop each microfrontend as a separate Angular application using the Angular CLI.
2. Use lazy loading to asynchronously load each microfrontend on the client-side as needed.
3. Use the Angular Universal module to render each microfrontend on the server-side.
4. Use a web server like NGINX to route the requests to the appropriate microfrontend based on the URL.

By using this approach, each microfrontend can be developed and deployed independently of the others, allowing for greater flexibility and scalability. Additionally, by rendering the application on the server-side, the initial load time can be reduced, improving the user experience.
