See some of my little demos here:

http://webassembly.arsdnet.net/

a blog post about it
http://dpldocs.info/this-week-in-d/Blog.Posted_2020_08_10.html

and some source for the support code
http://github.com/adamdruppe/webassembly/


the approach I took is a miniature custom runtime but there's 
also the possibility of a druntime port to the wasi emscripten 
uses

though none of these are complete.


Anyway, the point of my little demo is in 50 KB of webasm I had 
my basic game demos running in the browser.

I did partial source ports that just call out to javascript 
instead of relying on a copied stdlib. Makes more sense that way 
to me and also produces smaller binaries.
