How do I minimize to tray when I close a Chrome app?

Question

I would like to minimize my app to the tray when the user presses close, similar to how Spotify operates. It doesn't have to a Windows system tray, but I do want my window to be closed.

However, the scripts in the webpage should be running so that a close behaves similarly to a minimize without a window.

Is there a way to do this besides keeping scripts in the manifest.json?

Answer 1

No way to do this.

The Close icon is system level. Codes in Chrome app can not work with it.

Answer 2

You can remove the native window controls using

chrome.app.window.create("any.html", { frame: "none" })

You can hide a window using

chrome.app.window.current().hide()

And show it using

chrome.app.window.current().show()
