Angular Universal is a technology within the Angular framework that allows for server-side rendering (SSR) of Angular applications. This means that the web pages are rendered on the server instead of in the browser, which can significantly improve the performance and search engine optimization (SEO) of web applications[1][2][4][5][6][9].
How Angular Universal Works
Angular Universal works by pre-rendering the Angular application on the server side before sending it to the client. When a user makes a request to the server for a specific page, the server generates the HTML for that page and sends it to the client, instead of sending the Angular application code[2]. This pre-rendered page can be displayed immediately by the browser, even before all JavaScript is downloaded and executed. This approach enhances the user experience, particularly on slower networks or less powerful devices, by showing content faster.
Benefits of Angular Universal
Improved Performance and SEO: By rendering pages on the server, Angular Universal improves the load time of web pages and makes them available to search engines for indexing, which is crucial for SEO[1][2][4][6].
Enhanced User Experience: Users see the content immediately without waiting for all JavaScript to load, which can significantly improve the perceived performance of the application[1][2][4].
Social Media Compatibility: Server-rendered pages are fully equipped with all meta tags needed for social media platforms, improving link previews on these platforms[1].
Implementation
To implement Angular Universal, developers typically use the @nguniversal/express-engine module, which integrates with Node.js and Express server frameworks. This setup involves modifying the Angular application to han...
