What is server-side rendering?

Educative Answers Team

Server-side rendering (SSR), is the ability of an application to contribute by displaying the web-page on the server instead of rendering it in the browser. Server-side sends a fully rendered page to the client; the client’s JavaScript bundle takes over and allows the SPA framework to operate. There is also client-side rendering which slows down the procedure of viewing and interacting with the web page.

Advantages of using server-side rendering

  • It enables pages to load faster which provides a better user experience.

  • It plays an important role in SEO (search engine optimization) and correctly indexes webpages. This happens because Google favors web pages with faster load time.

  • It provides body to the HTML pages for all server ships.

  • It assists with​ loading the page when the user has a​ slow internet connection.

  • It assists in loading the page when the user has an outdated device.
