Build Configurations

Once the module installation is complete, you can simply build the platform package with the command below.

# For Windows (.exe, .appx)
$ npm run build:win

# For macOS (.dmg)
$ npm run build:mac

# For Linux (.rpm, .deb, .snap)
$ npm run build:linux

The built packages can be found in release/{version} location.

Build settings for projects that use Native Node modules

For projects that use the Native Node Module, add the following script to your package.json: When installing dependencies, electron-builder will take care of any modules that require rebuilding.

{
  "scripts": {
    "postinstall": "electron-builder install-app-deps"
  }
}

For more information, please refer to the following article: https://webpack.electron.build/dependency-management#installing-native-node-modules

What do I need to do for a multi-platform build?

macOS is recommended if you want to build multiple platforms simultaneously on one platform. Because it can be configured with just a few very simple settings.

You can perform multi-platform builds at once with the following command. Alternatively, you can just do it for the OS you want via the individual build commands above.

$ npm run build

Multipass configuration may be required for Linux builds. Learn more about Multipass through the following link: https://multipass.run

Reduce bundle size by excluding development files

You can exclude files you don't need at build time by adding a file pattern to the files property of electron-builder.json5. This will save bundle capacity.

Below is an unnecessary node_modules file pattern that can further save bundles. Depending on the project, using the rules below may cause problems, so please review it before using.
