electron-background
Launch an Electron application from the command line as a detached application. The command line will return immediately, and the application will not attach to your active terminal.
CLI
Start your application as you normally would except using electron-background instead of electron:
npx electron-background .API
I can't see why you might want this, but if you do... why not:
const electronBackground = require('electron-background');
electronBackground(['.']);
// you can now exit if you want, the app will stay running
process.exit();
