Kadabra

HTTP/2 client for Elixir

Written to manage HTTP/2 connections for pigeon. Very much a work in progress.

Installation

Requires Elixir 1.6/OTP 19.2 or later.

Add kadabra to your mix.exs:

def deps do
  [
    {:kadabra, "~> 0.6.2"}
  ]
end

Usage

{:ok, pid} = Kadabra.open("https://http2.codedge.dev")
Kadabra.get(pid, "/")
receive do
  {:end_stream, %Kadabra.Stream.Response{} = stream} ->
  IO.inspect stream
after 5_000 ->
  IO.puts "Connection timed out."
end

%Kadabra.Stream.Response{
  body: "<html>\\n<body>\\n<h1>Go + HTTP/2</h1>\\n\\n<p>Welcome to..."
  headers: [
    {":status", "200"},
    {"content-type", "text/html; charset=utf-8"},
    {"content-length", "1708"},
    {"date", "Sun, 16 Oct 2016 21:20:47 GMT"}
  ],
  id: 1,
  status: 200
}

Making Requests Manually

{:ok, pid} = Kadabra.open("https://http2.codedge.dev")

path = "/ECHO" # Route echoes PUT body in uppercase
body = "sample echo request"
headers = [
  {":method", "PUT"},
  {":path", path},
]

Kadabra.request(pid, headers, body)

receive do
  {:end_stream, %Kadabra.Stream.Response{} = stream} ->
  IO.inspect stream
after 5_000 ->
  IO.puts "Connection timed out."
end

%Kadabra.Stream.Response{
  body: "SAMPLE ECHO REQUEST",
  headers: [
    {":status", "200"},
    {"content-type", "text/plain; charset=utf-8"},
    {"date", "Sun, 16 Oct 2016 21:28:15 GMT"}
  ],
  id: 1,
  status: 200
}
