Distributed PubSub and Presence platform for the Phoenix Framework

Addphoenix_pubsub to your list of dependencies inmix.exs:

defdepsdo[{:phoenix_pubsub,"~> 2.0"}]end

Then start your PubSub instance:

defmoduleMyAppdouseApplicationdefstart(_type,_args)dochildren=[{Phoenix.PubSub,name:MyApp.PubSub}]opts=[strategy::one_for_one,name:MyApp.Supervisor]Supervisor.start_link(children,opts)endend

Now broadcast and subscribe:

Phoenix.PubSub.subscribe(MyApp.PubSub,"user:123")Phoenix.PubSub.broadcast(MyApp.PubSub,"user:123",:hello_world)

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

$ mixtest --exclude clustered

If you have issues running the clustered tests try running:

$ epmd -daemon

before running the tests.
