Detecting Online/Offline Status in Javascript

Learn how to detect if the user is online or offline and handle events if a change in the online/offline stateย occurs.

We can detect if the user is online or offline by using the online property on the navigator object which will return true if the user is connected to the internet, otherwise it returns false.

Additionally, online and offline events will be triggered if the user’s internet connections state changes. So we can add an online and offline event listener to the window and perform respective actions based on the online and offline state.
