Phoenix.PubSub

Distributed PubSub and Presence platform for the Phoenix Framework

Installation

1. Add phoenix_pubsub to your list of dependencies in mix.exs:

   def deps do
   [{:phoenix_pubsub, "~> 1.0"}]
   end

2. Ensure phoenix_pubsub is started before your application:

   def application do
   [applications: [:phoenix_pubsub]]
   end

Initialization (without Phoenix)

defmodule MyApp do
  use Application

  def start(_type, _args) do
    import Supervisor.Spec, warn: false

    children = [
      supervisor(Phoenix.PubSub.PG2, [MyApp.PubSub, []])
    ]

    opts = [strategy: :one_for_one, name: MyApp.Supervisor]
    Supervisor.start_link(children, opts)
  end
end

Testing

Testing by default spawns nodes internally for distributed tests. To run tests that do not require clustering, exclude the clustered tag:

$ mix test --exclude clustered

If you have issues running the clustered tests try running:

$ epmd -daemon

before running the tests.
