Hide the window when you press the close button on the electron app for Mac OSX

By default, when you press the close button, the browserWindow quit event is called, but the app quit event does not occur.
App-side quit events are called when the app ends, such as Cmd+Q.

Electron app events are officially well written.
http://electron.atom.io/docs/v0.36.8/api/app/ #events

If the questioner receives everything he wants to do as if he doesn't want to close the app itself even if he closes the window, that's the default.If not, please review your code.You should have shut down the app when you closed the window.

If you want to display the window again when you click Dock, like other apps, why don't you get the event when the electron is activated and generate the window again?

app.on('activate', function(){
  if(mainWindow==null){
    mainWindow = new BrowserWindow();
  }
});

If you don't want the state to return to its initial state, you can save the state of the app when you close it (you can get the event when you close it) and write a code that restores the state when you regenerate the window.
