This is an example of a udp client and server using elixir.

UdpClientServer

Simple client server using UDP (erlang's :gen_udp library) in elixir This leverages the elixir-socket, which in turn is a wrapper around get_tcp, gen_udp, gen_tscp and ssl from erlang.

Installation

Simply clone this repo, then run mix deps.get to fetch all the dependencies

Playing with the repo

The code is in lib/udp_client_server.ex. Currently, this doesn't run anything by default. To run it, I suggest opening 2 iex shells (iex is the elixir REPL), loading up the context of the repo.

Window 1: server

iex -S mix
Erlang/OTP 20 [erts-9.0] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

Interactive Elixir (1.4.5) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> UdpClientServer.launch_server

Window 2: client

iex -S mix
Erlang/OTP 20 [erts-9.0] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

iex(1)> UdpClientServer.send_data("hello")
:ok
