Grunt task for compiling Facebook React's JSX templates into JavaScript.

It also works great with grunt-browserify!

Getting Started

This plugin requires Grunt ~0.4.0

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-react --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-react');

The "react" task

Overview

In your project's Gruntfile, add a section named react to the data object passed into grunt.initConfig().

grunt.initConfig({
  react: {
    single_file_output: {
      files: {
        'path/to/output/dir/output.js': 'path/to/jsx/templates/dir/input.jsx'
      }
    },
    combined_file_output: {
      files: {
        'path/to/output/dir/combined.js': [
          'path/to/jsx/templates/dir/input1.jsx',
          'path/to/jsx/templates/dir/input2.jsx'
        ]
      }
    },
    dynamic_mappings: {
      files: [
        {
          expand: true,
          cwd: 'path/to/jsx/templates/dir',
          src: ['**/*.jsx'],
          dest: 'path/to/output/dir',
          ext: '.js'
        }
      ]
    }
  },
})

Recommended Usage

Writing your applications in CommonJS format will allow you to use Browserify to concatenate your files. Plus, with grunt-react, your templates will be converted from JSX to JS automatically!

First, install grunt-browserify to your project:

npm install grunt-browserify --save-dev

Second, register grunt-browserify in your Gruntfile:

grunt.loadNpmTasks('grunt-browserify')

Finally, add the following task to your Gruntfile:

browserify:     {
  options:      {
    transform:  [ require('grunt-react').browserify ]
  },
  app:          {
    src:        'path/to/source/main.js',
    dest:       'path/to/target/output.js'
  }
}

You've successfully concatenated your JSX & JS files into one file!

Options

options.extension

Type: String Default value: js

Extension of files to search for JSX-syntax & convert to JS.

options.ignoreMTime

Type: Boolean Default value: false

Speed up compilation of JSX files by skipping files not modified since last pass.


Usage Examples

Recommended Options

I recommend naming your React Components with the .jsx extension:

/**
 * @jsx React.DOM
 */

var MyComponent = React.createClass({
  ...
  render: function() {
    return (
      <p>Howdy</p>
    );
  }
});

Then, set your Gruntfile to use:

grunt.initConfig({
  react: {
    files: {
      expand: true,
      cwd: 'path/to/jsx/templates/dir',
      src: ['**/*.jsx'],
      dest: 'path/to/output/dir',
      ext: '.js'
    }
  },
})

This will output the following:

/**
 * @jsx React.DOM
 */

var MyComponent = React.createClass({displayName: 'MyComponent',
  render: function() {
    return (
      React.DOM.p(null, "Howdy")
    );
  }
});

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.

Release History

v0.6.0

  • Task changes to allow for flexible file options as found in the grunt-contrib-* projects.
  • Taking hints from grunt-contrib-less to allow for compiling single files separately, dynamic mappings and combining.
  • Removed extension option as this is determined by flexible file matching now.
  • Removed MT time ignoring, this can be easily done with the grunt-newer plugin.
  • Errors are ignored and skipped by default to match how other grunt plugins work.
