If you need to use an HTTP proxy you can set these environment variables.

If you want to change the architecture that is downloaded (e.g., ia32 on an x64 machine), you can use the –arch flag with npm install or set the npm_config_arch environment variable:

npm install --arch=ia32 electron

Usage

First, you have to write an Electron application.

Then, you can run your app using:

electron your-app/
