Angular Universal is nothing but a robust pre-rendering solution. It allows you to use both client-side and server-side rendering with the same application, ensuring faster loading time and an interactive user interface.
Angular Universal is an SSR and pre-rendering solution. It allows you to use both server-side and client-side rendering in the same application and prefetch HTML pages for all app URLs. A search engine robot serves this page, and the content is crawled without problems. For real users, Universal provides code for typical client applications along with static HTML. The initial page content is loaded from static HTML, and the client application takes over the page to provide an interactive user interface.
