View Source Event handling

Event handling is how your bot application will interact with the information sent from Discord over a websocket connection. By defining an event handler for an event, when something like a message is created or a channel is deleted, your application can perform an action as a result of that event.

Nostrum uses Erlang's :pg module to determine which consumers are interested in events, via Nostrum.ConsumerGroup. This allows dynamic subscriptions at runtime, even across nodes. Events are dispatched to group members as they appear from the Discord Gateway after ingestion into the cache.

To see the documentation on handling events of provided consumers, please see Nostrum.Consumer.
