react-scripts-ssr

Create React apps with server-side rendering (SSR) with no configuration

Installation

npm install react-scripts-ssr --save-dev

Getting started

Steps

Step 1

In the scripts section of your package.json:

• Replace "start": "react-scripts start" with "start": "react-scripts-ssr start",
• Add "build-server": "react-scripts-ssr build-server",

Step 2

• npm install express --save
• Create the following file in src/server.js

const React = require("react");
const express = require("express");
const { createSSRMiddleware } = require("react-scripts-ssr");
const { renderToString } = require("react-dom/server");
import App from "./App";
 
const server = express();
 
server.use(
  createSSRMiddleware((req, res, next) => {
    const body = renderToString(<App />);
    next({ body }, req, res);
  })
);
 
const PORT = process.env.REACT_APP_SERVER_SIDE_RENDERING_PORT || 8888;
server.listen(PORT, () => {
  console.log(`server running on port ${PORT}`);
});

You can edit the server.js file with your custom code and other middlewares.

Step 3

npm start

Caveats

It only works with Create React App version 2
