What forces layout/reflow. The comprehensive list.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics
  • elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Redux Chaos Monkey

This is a proof of concept which allows you to replay system events in a random order each time to make sure your UI can tolerate variable states.

I'm not sure if this is worthy of its on open source project with additional features like changing play back time, whitelisting/blacklisting actions etc but figured I'd put this out there to see if it piques anyones interest.

See a video of this in action here: [https://www.youtube.com/watch?v=wkoukONfwmA](Video on YouTube).
