Middleware for building full page apps using React, JSX, and CommonJS.

If you want to get started with server rendered React apps, go directly to react-page. This project is the implementation of the router/server-side-page-assembler/packager.


  • Server-side JavaScript rendering of pages/apps using React.
  • Pages rendered on server, seamlessly brought to life in the browser.
  • No special glue code to write - "Just works" on client/server.
  • CommonJS + React + optional JSX.


- node (a more recent version)
- npm


Let npm do all the installing - just create a directory structure anywhere as follows:

 ├── package.json              # Add npm dependencies here.
 ├── server.js                 # Start web server with `node server.js`
 └── src                       # All your application JS.
     ├── index.js              # localhost:8080/index.html routed here
     └── pages                 # Configure the page root using pageRouteRoot
         └── about.js          # localhost:8080/about.html

List your dependencies in package.json:

// Shows how to depend on bleeding edge versions. One niceness of
// `react-page-middleware`, is depending on the main React repo as
// `require('React')` Not all JS packagers understand the pure git repo for
// React.
"dependencies": {
  "React": "git://",
  "react-page-middleware": "git://",
  "connect": "2.8.3"

Download your project's dependencies:

cd yourProject
npm install

Create a server.js file that requires react-page-middleware, and set the proper directory search paths and routing paths.

var reactMiddleware = require('react-page-middleware');
var REACT_LOCATION = __dirname + '/node_modules/react-tools/src';
var ROOT_DIR = __dirname;
var app = connect()
    logTiming: true,
    pageRouteRoot: ROOT_DIR,           // URLs based in this directory
    useSourceMaps: true,                // Generate client source maps.
    projectRoot: ROOT_DIR,          // Search for sources from
    ignorePaths: function(p) {          // Additional filtering
      return p.indexOf('__tests__') !== -1;
  .use(connect['static'](__dirname + '/src/static_files'));

Run the server and open index.html:

node server open http://localhost:8080/index.html

The react-page project has a much more thorough explanation of the motivation and features.

JavaScript-centric Routing And Page Rendering For JavaScript.

The default router is JavaScript-centric. You simply specify the path to the JS component you want to use to render the entire page. react-page for more information about the routing.

Source Maps

react-page-middleware has them.

Run and Build on the Fly

Just hit your browser's refresh button to run an always-up-to-date version of your app.

  • Dynamically packages/compiles your app on each server request.


react-page-middleware is a rapid development environment where you can experiment with entirely new ways of building production web apps powered by React. It provides a common environment that allows sharing of modules client/server architecture prototypes.

In order to use this technology in a production environment, you would need to audit and verify that the server rendering strategy is safe and suitable for your purposes.

  • In particular, you would want to ensure that a proper server sandbox is enforced. However, react-page does run your UI rendering code inside of contextify as a preliminary sandbox.

  • The packaging/transforming features of react-page would not be needed in a production environment where the packages can be prebuilt once, stored in a CDN and not be repackaged on the fly, but the server rendering feature is very compelling for production environments where page load performance is of great concern.

  • Among other things, additional connect middleware should be added to prevent stack traces from showing up in the client.
