Creating a Background Process?

Question

I'm wondering, how can we create a background process which notifies users (even after terminating the app)?

I've tried creating a window with skipTaskbar:true , but it can't be initiated without user's gesture.

One library called Background.js to handle a few scenarios: a sequential background queue (based on the WorkerQueue library), a list of jobs where each is called on every timer, and an array iterator to help break up your work into smaller chunks. Examples and code here:

Or

You can also use below code for background task.

<html>
<body>

<p>Count numbers: <output id="result"></output></p>
<button onclick="startWorker()">Start Worker</button> 
<button onclick="stopWorker()">Stop Worker</button>

<p><strong>Note:</strong> Internet Explorer 9 and earlier versions do not support Web Workers.</p>

<script>
var w;

function startWorker() {
    if(typeof(Worker) !== "undefined") {
        if(typeof(w) == "undefined") {
            w = new Worker("demo_workers.js");
        }
        w.onmessage = function(event) {
            document.getElementById("result").innerHTML = event.data;
        };
    } else {
        document.getElementById("result").innerHTML = "Sorry, your browser does not support Web Workers...";
    }
}

function stopWorker() { 
    w.terminate();
    w = undefined;
}
</script>

</body>
</html>
