TimedQ.js

Javascript timed processing queue (and queue manager). Useful as a non render blocking processing queue in the browser to eliminate jank in animations and page elements.

The problem

In the browser, DOM animations and Javascript execution run in a single thread. If you need to process large amounts of data while keeping the browser responsive you must use some sort of processing queue or a web worker.

Traditional queues

DISCLAIMER: By traditional I mean how I’ve traditionally done them.

• Hardcoded batch sizes have inconsistent execution time between different devices and browsers
• Makes your code subject to more profiling reviews (could be a good thing too :wink:)

Web workers

Have their own set of limitations that make this library appealing:

• Web workers cannot directly interact with the DOM
• Communicating with web workers is done through messages exchanges of serialized data, this can be a pain for already established projects

The solution

A self-adjusting queue management system which runs batches within reasonable timeframes, giving the browser time to update and draw.
