@timfish/forge-externals-plugin

When using Electron with Webpack, the easiest way to support native modules is to add them to Webpack externals configuration. This tells webpack to load them from node_modules via require():

module.exports = {
  module: {
    rules,
  },
  plugins: plugins,
  resolve: {
    extensions: [".js", ".ts", ".jsx", ".tsx", ".css"],
  },
  externals: {
    // Always load `native-hello-world` via require
    "native-hello-world": "commonjs2 native-hello-world",
  },
};

This works in development but with Electron Forge + Webpack, node_modules gets excluded during packaging so the modules are missing in the packaged app.

This plugin should be added after @electron-forge/plugin-webpack and it ensures that your external modules and their dependencies are included in the packaged app.
