HTTP/2 implementation in Crystal. Heavily inspired by igrigorik/http-2.

Not usable yet.

Add this to your application's shard.yml:

dependencies:
  http2:
    github: markauskas/http2

A very primitive HTTP/2 server can be implemented as follows:

require "http2"

def handle_connection(socket)
  conn = HTTP2::Server.new(socket)
  conn.on(:stream) do |emittable|
    stream = emittable.to_stream
    stream.on(:request) do |emittable|
      stream = emittable.to_stream
      puts "NEW REQUEST: #{stream.headers.inspect}"
      stream.send_response(
        [[":status", "200"], ["content-type", "text/html"]],
        "<h1>HELLO HTTP/2!</h1>".to_slice
      )
    end
  end
  conn.work
end

server = TCPServer.new("127.0.0.1", 8080)
loop { spawn handle_connection(server.accept) }

The server doesn't have any kind of protocol negotiation support. This task is left to a load balancer for now. For development I'm using HAProxy for this.
