What is Angular Universal or Angular SSR?

Angular Universal also known as Angular SSR (Server side rendering) is a technology that renders Angular applications on the server.

A regular Angular application executes in the browser, rendering pages in the DOM in response to user actions. However Angular Universal executes on the server, generating static application pages that later get bootstrapped on the client.

With angular universal, the application generally renders more quickly, giving users a chance to view the application layout before it becomes fully interactive.

Advantages of using Angular universal.

  • Facilitate web crawlers through search engine optimization (SEO).
  • Improve performance on mobile and low-powered devices.
  • Show the first page quickly with a first-contentful paint (FCP).
