Webpack plugin to keep extension's manifest file in sync with package.json.

Installation

npm install --save-dev chrome-manifest-sync-webpack-plugin

Available config options

• source - path to your manifest.json.

  Default: './manifest.json'

• properties - array of properties to copy.

  Default:

  [
      'version',
      'description',
      'author',
      // Copies `homepage` from `package.json`
      // to `homepage_url` in `manifest.json`
      { homepage_url: 'homepage' },    
  ]

Webpack configuration

const { ChromeManifestSyncWebpackPlugin } = require('chrome-manifest-sync-webpack-plugin');

module.exports = {
    // ...
    plugins: [
        // ...
        new ChromeManifestSyncWebpackPlugin({
            source: './src/manifest.json',
            properties: [ 'version', 'description' ],
        }),
        // ...
    ],
    // ...
};

Now, every time you save changes to package.json or src/manifest.json, Webpack will emit updated manifest to your output directory.
