An HTTP/2 and HTTP/3 server and client implementation in pure Ruby.
Passes h2spec and hpack-test-case.
Only works with Ruby 4.1.0+
An example using HTTP/2 is here: examples/fetch_google.rb
An example using HTTP/3 is here: examples/quic_fetch.rb
Just a demo server:
# frozen_string_literal: true
require "kantan"
require "socket"
require "logger"
class MyApp < Kantan::Handler
def on_request stream
stream.respond [[":status", "200"]], body: "hello"
end
end
server = TCPServer.new "127.0.0.1", 8888
logger = Logger.new $stderr
logger.debug "port #{8888}"
while true
client_fd = server.sysaccept
logger.debug "new connection"
Ractor.new(client_fd) do |c_fd|
c = Socket.for_fd(c_fd)
c.autoclose = true
c.setsockopt(Socket::IPPROTO_TCP, Socket::TCP_NODELAY, 1)
session = Kantan::Session.new(c, handler: MyApp.new)
session.receive
session.join
end
end
