It is not the-swank's port

[mittorn]

The_Swank is only hosting server for me:
http://mittorn.the-swank.pp.ua/xash-em/
I am port author, you may ensure it by viewing commits in engine source code. So please, fix readme
Source code is here:
https://github.com/FWGS/xash3d
https://github.com/FWGS/mainui_cpp
https://github.com/FWGS/emscripten
https://github.com/FWGS/emscripten-fastcomp
https://github.com/FWGS/hlsdk-xash3d
https://github.com/FWGS/wsproxy
Build instructions:
https://github.com/FWGS/xash3d/blob/master/ports/README.emscripten.md
If you want to host server with multiplayer support on https, you need to add wss:// support to wsproxy and run it with server's certificate
It was removed because https connection gives big overhead when creating too many connections (for example, scanning for internet servers).
Also, i updated server recently (all except html pages), you may update repo too.
gzip files is not needed, it is busybox httpd feature: it uses precompressed gzip files when browser supports it. other http servers have own gzip cache

What I meant was that I took the code from http://mittorn.the-swank.pp.ua/xash-em/xash.html. Sorry if it was misleading. Thanks for the other info btw, very helpful! I'll update the repo ASAP.

I will change it to say "mittorn" instead in the description.

Now i am rewriting js part. I added offline cache support and i'll add IDB cache for zip soon

Repo clonning hanged on objects unpacking. git is not very good for binaries
