Socket.IO server for Deno

Hello everyone!

I'm happy to announce that Socket.IO is now compatible with Deno, which is a runtime for JavaScript and TypeScript written in Rust.

Usage:

import{ serve }from"https://deno.land/std@0.150.0/http/server.ts";
import{ Server }from"https://deno.land/x/socket_io@0.1.1/mod.ts";

const io =newServer();

io.on("connection",(socket)=>{
console.log(`socket ${socket.id} connected`);

 socket.emit("hello","world");

 socket.on("disconnect",(reason)=>{
console.log(`socket ${socket.id} disconnected due to ${reason}`);
});
});

awaitserve(io.handler(),{
 port:3000,
});

And then run with:

$ deno run --allow-net index.ts

The API is very similar to the one exposed by the Node.js implementation.

Next steps:

client implementation
compatibility with the Node.js ecosystem (msgpack parser, adapters, admin UI, ...)

Feedback is welcome!
