grunt-crx-auto-reload

Pure Javascript solution for automatically reloading a Chrome extension.

WARNING:

:warning: This solution will spike your processor so disable the extension when you have stopped development. Moreover, remove the reload.js reference on the manifest.json production version.

Getting Started

This plugin requires Grunt.

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-crx-auto-reload --save-dev

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

grunt.loadNpmTasks('grunt-crx-auto-reload');

The "crx_auto_reload" task

Overview and Quickstart Guide

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

grunt.initConfig({
  crx_auto_reload: {
    options: {
      extensionDir: 'app/'
    },
    default: {}
  },
})

Next, add reload.js as a background script in manifest.json.

{
  // omitted.
  "default_locale": "en",
  "background": {
  "scripts": [
      "reload.js" // The reload.js file will be created on the first run of crx_auto_reload
    ]
  }
  // omitted.
}

This plugin is meant to be used in conjunction with grunt watch e.g.

grunt.initConfig({

    watch: {
        crx_auto_reload: {
          files: ['app/scripts/{,*/}*.js', 'app/manifest.json', 'app/templates/{,*/}*.html'],
          tasks: ['crx_auto_reload']
        }
    },
    crx_auto_reload: {
        options: {
          extensionDir: 'app/'
        },
        default: {}
    }
});

In the above example, whenever there are changes to the project's Javascript or HTML files the crx_auto_reload task kicks off creating a reload.html in the designated extensionDir with just a simple timestamp. Here would be the sample contents of reload.html.

On the first run of crx_auto_reload the reload.js will be created in the designated extensionDir. Its job is to check the reload.html file every second to see if the timestamp has changed. If the timestamp has changed a chrome.runtime.reload() will be executed on reload.html. This eliminates the need to go to chrome://extensions and perform a manual refresh.

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.
