Development vs. Production Builds #

We provide two versions of React: an uncompressed version for development and a minified version for production. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages.

If you're just starting out, make sure to use the development version.

We're using unpkg to serve these files. This is a free service with the goal to provide a hassle-free CDN for npm package authors. React is also available on other free CDNs including cdnjs and jsDelivr. If you have concerns with relying on an external host, we always recommend that you download React and serve it from your own servers.

npm #

We recommend using React from npm with a bundler like browserify or webpack. You can use the react and react-dom packages. After installing it using npm install --save react react-dom, you can use:

var React = require('react');
var ReactDOM = require('react-dom');
ReactDOM.render(<App />, ...);

Each of the add-ons lives in its own package.

Note: by default, React will be in development mode. To use React in production mode, set the environment variable NODE_ENV to production (using envify or webpack's DefinePlugin). A minifier that performs dead-code elimination such as UglifyJS is recommended to completely remove the extra code present in development mode.

Bower #

$ bower install --save react
