Here you go, mate:
Convert your AS3 file to Canvas:

There are some limitations:
Color effects, radial gradients, animated masks - you will get warnings when you publish or things might not look like they should so you will have to figure out alternative ways of achieving the same results by trial and error.
These are the settings that will not export your vectors as bitmaps/spritesheet, i.e. will keep them vector:

You can change the Export Image Assets > Export as to experiment with the other options.
You will end up with a HTML and JS files and an images folder that holds the preloader GIF.
If you open the HTML you will see that it calls
<script src="https://code.createjs.com/1.0.0/createjs.min.js"></script>
I'd rather host a copy of createjs on my server, so put it somewhere and change that path.
Embed the HTML as an iFrame.
