Optional options

all                equivalent to --platform=all --arch=all

helper-bundle-id   bundle identifier to use in the app helper plist
ignore             do not copy files into App whose filenames regex .match this string
prune              runs `npm prune --production` on the app
overwrite          if output directory for a platform already exists, replaces it rather than skipping it
asar               packages the source code within your app into an archive
sign               should contain the identity to be used when running `codesign` (OS X only)
version-string     should contain a hash of the application metadata to be embedded into the executable (Windows only).
                   These can be specified on the command line via dot notation,
                   e.g. --version-string.CompanyName="Company Inc." --version-string.ProductName="Product"
                   Keys supported:
                   - CompanyName
                   - LegalCopyright
                   - FileDescription
                   - OriginalFilename
                   - FileVersion
                   - ProductVersion
                   - ProductName
                   - InternalName
                   

This will:

• Find or download the correct release of Electron
• Use that version of electron to create a app in <out>/<appname>-<platform>-<arch>

You should be able to launch the app on the platform you built for. If not, check your settings and try again.

Be careful not to include node_modules you don't want into your final app. electron-packager, electron-prebuilt and .git will be ignored by default. You can use --ignore to ignore files and folders, e.g. --ignore=node_modules/electron-packager or --ignore="node_modules/(electron-packager|electron-prebuilt)".

Building windows apps from non-windows platforms

If you run this on windows and you want to set the icon for your app using the --icon option, it requires running a thing called rcedit.exe (via this), which means you will need to install wine and have it available in your path. To do this on Mac OS you can brew install wine.
