This is no longer the recommended way to approach server side rendering with React. For an all-round solution look at a starter with next.js or remix

Clone the repo with git clone https://github.com/alexnm/react-ssr

Install dependencies with npm i

Run dev mode with npm run dev

Now open the browser and navigate to http://localhost:2048 and you get your server rendered React app. You can inspect the page source and see that the html coming from your local server has all the nodes defined in the React app.

• I tried to limit the complexity of the entire app to focus on the server side rendering part. Don't take the same shortcuts in your production app!
• We're starting the server with the index.js file which is in the root folder. This file loads the babel-register and sets up the babel plugins needed to run JSX and ESModules on the server.
• The node server needs to handle the static files from the dist folder.
• The entry point of the bundle is called client.js because it's the only part of our application that is not used for the server render.

Understand the different parts of server side rendering by going through each tag:

• Base example
• Adding React Router
• Adding Redux
• Data Fetching
• Using React Helmet
