A lightweight web-workers library for building multithreaded applications in browser.
DinoTask is built on top of HTML5 web-workers which provides an easy way of creating tasks that execute parallel in browser without blocking the UI thread.
<!doctype html>
<html>
<head>
<title>UI Freeze example</title>
</head>
<body>
<button id="normal">Normal</button>
<button id="uifreeze">CPU Intensive - UI Freeze</button>
</div>
<script>
document.getElementById("normal").addEventListener("click", function () {
console.log("Normal => I take less time to execute");
});
document.getElementById("uifreeze").addEventListener("click", function () {
console.log("UI Freeze => I start the loop and takes 5 to 10 seconds to execute.");
var startTime = new Date().getTime();
for (var j = 0; j < 1500; j++) {
for (var i = 0; i < 10000000; i++);
}
var endTime = new Date().getTime();
console.log("UI Freeze => Total time in seconds: " + ((endTime - startTime) / 1000));
});
</script>
</body>
</html>
With the above snippet, when you right click or left click your page or any button on the page, it will not respond since it is blocking UI thread.
<!doctype html>
<html>
<head>
<title>UI Freeze example</title>
<script src="DinoTask.js"></script>
</head>
<body>
<button id="normal">Normal</button>
<button id="uifreeze">CPU Intensive - UI Freeze</button>
</div>
<script>
document.getElementById("normal").addEventListener("click", function () {
console.log("Normal => I take less time to execute");
});
document.getElementById("uifreeze").addEventListener("click", function () {
console.log("UI Responsive => I will start the loop and takes 5 to 10 seconds to execute.");
DinoTask.create([], function () {
var startTime = new Date().getTime();
for (var j = 0; j < 1000; j++) {
for (var i = 0; i < 10000000; i++);
}
var endTime = new Date().getTime();
return "UI Responsive => Total time in seconds: " + ((endTime - startTime) / 1000);
}).run(function (result) {
console.log(result);
}).errorHandler(function (err) {
console.log(err);
});
});
</script>
</body>
</html>
With the above snippet, when you right click or left click your page or any button on the page, it will still respond since it is non-blocking UI thread. (It offloads the computation to other thread).
