how to detect if the user using Google Chrome in kiosk mode?

I want to know if the user is using chrome in kiosk mode if it is not for me to display a message to put teaching so she can use the resources that only the kiosk mode can provide

You can check the isKioskSession property on the launchData object you get from the chrome.app.runtime.onLaunched event.

chrome.app.runtime.onLaunched.addListener(function(launchData) {
  if (launchData.isKioskSession) {
      // yes, we are in kiosk mode
  }
});

EDIT

The above answer assumes that you are in a Chrome app. If you are trying to detect whether a page is in a Chrome browser launched with the --kiosk option, I don't know of a way to detect that. However, this is functionally equivalent to running in fullscreen mode, which you can detect with the Fullscreen API.

var fullscreenEnabled = document.fullscreenEnabled || document.mozFullScreenEnabled || document.webkitFullscreenEnabled;

    I think he was talking about normal Chrome running in Kiosk mode, not a Chrome app. The detect fullscreen code you mentioned is just for checking if the browser **supports** fullscreen, not if it's currently in fullscreen. Any other solutions? I have the same problem and detecting based on `screen.availHeight` and `window.innerHeight` doesn't work if the user zooms in, making it break. – s1h4d0w Jun 02 '17 at 07:10
  • mmm but if i want url bar to be visible i want to use --kiosk so no full screen, your solution may work with --kiosk-printing – shareef Nov 28 '17 at 18:13
