Angular Universal is a technology that is used to render Angular applications on the server. This process is called SSR (server-side rendering). A simple Angular application is executed on the browser as all the Angular applications are single-page applications, so the rendering always occurs on the browser. This process of rendering single-page applications is called the client-side rendering process (CSR). On the other hand, the Angular Universal is executed on the server, generating static application pages that later get bootstrapped on the client. That’s why Angular Universal application generally renders more quickly, giving users a chance to view the application layout before it becomes fully interactive.
Angular Universal refers to the server-side rendering (SSR) solution provided by the Angular framework. In traditional single-page applications (SPAs), the rendering of the user interface occurs in the browser. However, Angular Universal allows developers to render Angular applications on the server side before sending them to the client, improving the performance and search engine optimization (SEO) of the application.
As of my last knowledge update in January 2022, Angular Universal is a technology in the Angular framework that enables server-side rendering (SSR) for Angular applications. Server-side rendering refers to the process of rendering web pages on the server side rather than in the client’s browser. This can provide benefits such as improved performance, better SEO (Search Engine Optimization), and faster initial page loads.
With Angular Universal, you can run your Angular applications on the server, generating HTML on the server side and sending it to the client’s browser. This approach helps in delivering a fully rendered page to the user, reducing the time it takes for the application to become interactive.
Angular Universal can be used to create isomorphic or universal applications, meaning that the same codebase can be executed on both the server and the client. This facilitates a seamless transition between server-side and client-side rendering, providing a better user experience.
Keep in mind that Angular and its features might have evolved since my last update in January 2022, so it’s always a good idea to check the official Angular documentation or other reliable sources for the latest information on Angular Universal and its features, especially if you’re working with a specific version like Angular 8
