Jsdom: window.requestAnimationFrame is not defined

Created on 29 Aug 2017 · 4Comments · Source: jsdom/jsdom

Basic info:

Node.js version: v8.0.0
jsdom version: 11.2.0

Using jsdom with jsdom-global to test a program that uses requestAnimationFrame. On first test I got

requestAnimationFrame is not defined

Then I added the window namespace and still got that it was not defined. Is there no implementation for it on jsdom and is there a workaround?

Yes I think faking it with setTimeout would be great just to make code with it work. I bet no one would really ever expect it to have the original rAF behavior

Indeed this is not yet implemented in jsdom. You can always add a shim to window, potentially before any parsing: https://github.com/tmpvar/jsdom#intervening-before-parsing

I wonder if we should implement this, with just a 1/60 of a second timer. Or is that too misleading, since jsdom does not paint the screen, ever?

Should also cancelAnimationFrame be made?
