Angular Universal is a server-side rendering module for Angular applications.

Better Perceived Performance

First time users of your application will instantly see a server rendered view which greatly improves perceived performance and the overall user experience. According to research at Google, the difference of just 200 milliseconds in page load performance has an impact on user behavior.

Optimized for Search Engines

Although Googlebot crawls and renders most dynamic sites, many search engines expect plain HTML. Server-side pre-rendering is a reliable, flexible and efficient way to ensure that all search engines can access your content.

Site Preview

Ensure that Facebook, Twitter and all other social media apps correctly display a preview image of your app.
