ReactJS preprocessed index.html

Question

I'm aware that Facebook uses React for developing their front end. I'm a little bit new to ReactJS, and so far I have seen that the server returns the index.html and loads the components on the root div.

Looking at the source code of facebook.com, I realized that the response index.html has some preprocessed data and different scripts. Can anyone tell me how they do for responding with a preprocessed index.html?

Answer 1

You have to render react on the server to enable such functionality. Using a framework like Nextjs would help you achieve this.
