To get you up and running as fast as possible with the Webpack bundler, we provide a template that makes use of the @electron-forge/plugin-webpack module, plus some preset Webpack configuration options. This is by far the quickest way to getting a working Webpack setup with Electron.
Once you've initialized the template, you'll need to run npm startin the generated directory. See the Webpack Plugin documentation for Electron Forge-specific configuration options.
