Server Side Rendering

There are a few reasons you may want to use Server-Side Rendering with your Angular application.

1. SSR helps with Search Engine Optimization. Search engines can parse the page since it is rendered on the server.
2. Socia media platforms like Facebook and Twitter can show a preview of the site when shared.
3. Once a webpage is rendered on the server, you can cache it and serve it much faster.

To implement server side rendering in your Angular application, you can use the Angular Universal package.
