yggdrasil v3.2.2 Yggdrasil.Publisher.Adapter.RabbitMQ View Source
Yggdrasil publisher adapter for RabbitMQ. The name of the channel should be a tuple with the name of the exchange and the routing key. The exchange should be a topic e.g:
Subscription to channel:
iex(1)> alias Yggdrasil.Channel
iex(2)> sub_channel = %Channel{
...(2)> name: {"amq.topic", "r_key"},
...(2)> adapter: Yggdrasil.Subscriber.Adapter.RabbitMQ
...(2)> }
iex(3)> Yggdrasil.subscribe(sub_channel)
:ok
iex(4)> flush()
{:Y_CONNECTED, %Channel{name: {"amq.topic", "r_key"}, (...)}}
Publishing message:
iex(5)> pub_channel = %Channel{
...(5)> name: {"amp.topic", "r_key"},
...(5)> adapter: Yggdrasil.Publisher.Adapter.RabbitMQ
...(5)> }
iex(6)> Yggdrasil.publish(pub_channel, "message")
:ok
Subscriber receiving message:
iex(7)> flush()
{:Y_EVENT, %Channel{name: {"amq.topic", "r_key"}, (...)}, "message"}
Instead of having sub_channel
and pub_channel
, the hibrid channel can be
used. For the previous example we can do the following:
iex(1)> alias Yggdrasil.Channel
iex(2)> channel = %Channel{name: {"amq.topic", "r_key"}, adapter: :rabbitmq}
iex(3)> Yggdrasil.subscribe(channel)
:ok
iex(4)> flush()
{:Y_CONNECTED, %Channel{name: {"amq.topic", "r_key"}, (...)}}
iex(5)> Yggdrasil.publish(channel, "message")
:ok
iex(6)> flush()
{:Y_EVENT, %Channel{name: {"amq.topic", "r_key"}, (...)}, "message"}
