Chrome.SidePanel on close/suspend/unload event

[Estefania Chavez Guardado]

Hi,

We are having issues to identify an event or way to find out whenever the sidepanel has been closed, the window has been closed or the tab has been closed. We don't want to inject content script. We need only to display a simple browser alert when this happens.

Does anyone has experience with it?

Thanks in advance and have a nice day :)

Open a port via chrome.runtime.connect from the side panel and listen to its onDisconnect event in the service worker or in the offscreen document. You'll need to keep the recipient context alive e.g. by sending a dummy message through the port every 20 seconds.

This will only work if they don't care when their app is hidden (the user has activated another side panel app).

Hi, thank you for your help! We were able to listen to those events :)
