Downloads an Electron release zip from GitHub.
Used by electron-prebuilt and electron-packager


Note: Requires Node >= 4.0 to run.
$ npm install --global electron-download
$ electron-download --version=0.31.1

const download = require('electron-download')

  version: '0.25.1',
  arch: 'ia32',
  platform: 'win32',
  cache: './zips'
}, function (err, zipPath) {
  // zipPath will be the path of the zip that it downloaded.
  // If the zip was already cached it will skip
  // downloading and call the cb with the cached zip path.
  // If it wasn't cached it will download the zip and save
  // it in the cache path.

If you don't specify arch or platform args it will use the built-in os module to get the values from the current OS. Specifying version is mandatory. If there is a SHASUMS256.txt file available for the version, the file downloaded will be validated against its checksum to ensure that it was downloaded without errors.
You can also use electron-download to download the chromedriver, ffmpeg, mksnapshot, and symbols assets for a specific Electron release. This can be configured by setting the chromedriver, ffmpeg, mksnapshot, or symbols property to true in the specified options object. Only one of these options may be specified per download call.
You can force a re-download of the asset and the SHASUM file by setting the force option to true.
If you would like to override the mirror location, three options are available. The mirror URL is composed as url = ELECTRON_MIRROR + ELECTRON_CUSTOM_DIR + '/' + ELECTRON_CUSTOM_FILENAME.
You can set the ELECTRON_MIRROR or NPM_CONFIG_ELECTRON_MIRROR environment variable or mirror opt variable to use a custom base URL for grabbing Electron zips. The same pattern applies to ELECTRON_CUSTOM_DIR and ELECTRON_CUSTOM_FILENAME:
## Electron Mirror of China

## or for a local mirror

You can set ELECTRONMIRROR in .npmrc as well, using the lowercase name:
