Logout User when browser or tab closed

[abhishek agarwal]

I want to call logout api when user close the browser or tab so the user login session clear from the backend i try to use onbeforeunload but this function also calls on reload i only want to call api when  user close browser.

Perhaps 

You can do timeout

Or check JavaScript inbuilt objects

While maintaining the session 

Hope that helps

Unfortunately, there is no guaranteed way to do that. You need to implement a heartbeat mechanism or ensure the app logout on start (strange but ensures the user has to login everytime)

In java script we have  window.onbeforeunload  event you can use that

[bastien lemaire]

Trust me window.onbeforeunload is not the correct way to do such task. As specified on the usage notes, the event is not guaranteed to fire.

There is in fact not guaranteed way to do what you require appart from using a heartbeat mechanism...

This method is also called on refresh I don't want to logout the user when he refresh the page I  only want to logout the user when he close the browser or tab. Can you please explain what is heartbeat mechanism?
