Get electron-download pre-compiled binnaries for every platform to local cache directory.

About

This will avoid electron-packager to re-download pre-compiled binaries for electron every time we are making a build.

How?

Create a file named package.js in ~/.electron and execute the following command to get the specified electron-download binary version for all platforms.

Usage:

$ node ~/.electron/package.js
or
node ~/.electron/package.js 1.4.15
