React Render

Usage no npm install needed!

<script type="module">
  import sequencemediaReactRender from 'https://cdn.skypack.dev/@sequencemedia/react-render';



Render isomorphic React apps and components in Node.

An example implementation of the companion package @sequencemedia/react-router-redux-render can be found in react-router-pagination-io.


In Express:

const express = require('express')

const app = express()
const port = 3000

const {
} = require('react-render')

const App = require('./path/to/react/app')

app.get('/', (req, res) => res.send(renderToString(App)))

app.listen(port, () => console.log(`Express ${port}`))

If renderToString encounters an error then it throws a 500 Internal Server Error. Otherwise, it returns a string.

You can supply App with props using the second argument:

renderToString(App, {})

(Since this is not a Redux app you are likely to use props.)

In this package

react-render exports three functions:

  1. renderToString
  2. renderToStaticMarkup
  3. render

renderToString generates <html /> including the attributes that React uses in ReactDOM.hydrate(). It implements ReactDOMServer.renderToString().

renderToStaticMarkup doesn't include those attributes. It's useful for using React as a rendering engine for static pages. It implements ReactDOMServer.renderToStaticMarkup().

render executes renderToString but returns a Promise which resolves to a string.
