Plugin for Webpack that keeps a Chrome extension's manifest file up-to-date with package.json.

Usage

Assuming you have a package.json file, make sure you have your manifest.json file also at the top directory. You may remove from it the following fields, which will be pulled from your package.json file:

• name
• description
• version
• author
• homepage_url

Now, create a Webpack config file if you haven't already, and add this plugin to your plugins list. An example webpack.config.js:

const ChromeManifestPlugin = require('chrome-manifest-plugin');

module.exports = {
  entry: {
      'content-script': './src/content-script.js'
  },
  plugins: [ new ChromeManifestPlugin() ]
};

Now, when running webpack, it will build a manifest.json which includes the same information as your package.json.
