Philae

Land a Elixir app onto a MeteorJs App

Connect to a Meteor app and subscribe to collections

There is still some wierdness in the DDP module w/ the Client API but for now you can implement a simple client like so

defmodule PlayerVoter do
  use GenServer

  def start_link do
    GenServer.start_link(__MODULE__, [], [])
  end

  def init([]) do
    {:ok, client_pid } = Philae.DDP.connect("ws://localhost:3000/websocket", __MODULE__, self)
    {collection, id} = Philae.DDP.subscribe(client_pid, "players")
    {:ok, %{client_pid: client_pid, subscription_id: id, collection: collection}}
  end

  def added(pid, message) do
    GenServer.call(pid, {:added, message})
  end

  def handle_call({:added, message}, _from, state) do
    IO.puts "We got here and got"
    IO.inspect message
    {:reply, :ok, state}
  end
end
