react-router-render

Render isomorphic _React_ apps and components in Node.

- Using _React Router_

_For React Router 7._

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

Example

In Express:

``javascript
const express = require('express')

const app = express()
const port = 3000

const routes = require('./path/to/routes')

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

app.get('/', ({ url: { path: pathname = '/' } }, res) => res.send(renderToString(routes, pathname)))

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

If React Router matches the pathname to a then renderToString returns a string.

If renderToString encounters an error then it throws a 500 Internal Server Error.

If renderToString cannot match the pathname to a then it throws a 404 Not Found.

In this package

react-router-render exports three functions:

1. renderToString
2. renderToStaticMarkup
3. render

renderToString generates 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.

Companion packages

2. @sequencemedia/react-redux-render for React Redux apps (without React Router)
2. @sequencemedia/react-render` for React apps (without React Router or Redux)
