Download the starter kit to get everything you need to get started with React. The starter kit includes React, the in-browser JSX transformer, and some simple example apps.
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.
The uncompressed, development version of React core with inline documentation.
The compressed, production version of React core.
The uncompressed, development version of React with add-ons.
The compressed, production version of React with add-ons.
All scripts are also available via CDNJS.
To install the JSX transformer on your computer, run:
$ npm install -g react-tools
For more info about the
jsx binary, see the Getting Started guide.
If you're using an npm-compatible packaging system like browserify or webpack, you can use the
react package. After installing it using
npm install react or adding
package.json, you can use React:
var React = require('react'); React.render(...);
If you'd like to use any add-ons, use
var React = require('react/addons'); instead.
Note: by default, React will be in development mode. To use React in production mode, set the environment variable
production. A minifier that performs dead-code elimination such as UglifyJS is recommended to completely remove the extra code present in development mode.
$ bower install --save react
