WorkerGlobalScope: online event

Note: This feature is only available in Web Workers.

The online event of the WorkerGlobalScope fires when the device reconnects to the internet.

Syntax

addEventListener("online", (event) => { })

ononline = (event) => { }

A generic Event.

The following code snippet shows an onoffline handler set inside a worker:

  console.log("Your worker is now online");
};

The same snippet, but using addEventListener():

self.addEventListener("online", () => {
  console.log("Your worker is now online");
});
