|
| 3 | An npm package to get you immediate access to [React](https://reactjs.org/),
|
| 4 | without also requiring the JSX transformer. This is especially useful for cases where you
|
| 5 | want to [`browserify`](https://github.com/substack/node-browserify) your module using
|
| 6 | `React`.
|
| 7 |
|
| 8 | **Note:** by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages.
|
| 9 |
|
| 10 | To use React in production mode, set the environment variable `NODE_ENV` to `production`. A minifier that performs dead-code elimination such as [UglifyJS](https://github.com/mishoo/UglifyJS2) is recommended to completely remove the extra code present in development mode.
