In 2012, I created IvanK.js - a Javascript library with the "Flash API" for quickly remaking ActionScript 3 games into the web environment. But it required WebGL, which as not very well supported back then.

I could remake several of my flash games quickly into web.

I used it, thanks for making it. (Did not released something with it, though)

I switched to EaselJS, as this was supposedly the official supported libary of Adobe Animate, but then later settled with pixijs.
