grunt-webext-builder

Grunt plugin for build chrome, firefox, opera and safari extensions

Getting Started

This plugin requires Grunt ~0.4.5

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-webext-builder --save-dev

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

grunt.loadNpmTasks('grunt-webext-builder');

The "webext_builder" task

Overview

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

grunt.initConfig({
  webext_builder: {
    <your_target_name>: {
      // List extension types you want to build
      targets: ["chrome-crx"],
      // Path to chrome extension private key (will be in ./.private.pem if not defined)
      privateKey: "/path/to/private/2049/RSA/key"
      // Mozilla Addons API credentials, go to https://addons.mozilla.org/en-US/developers/addon/api/key/ to receive it
      // It's better to store it in environment, not in this file
      "jwtIssuer": process.env.jwtIssuer,
      "jwtSecret": process.env.jwtSecret,
      files: {
        "extension/dest/dir": ["extension/source/dir"]
      }
    },
  },
});
