end

#on(pattern, async: false, **options) ⇒ Object

Subscribe this operation to events matching pattern.

Registration happens at class-load time and is bound to the bus that is active when the class is evaluated. Configure the bus before loading handler classes (e.g. in a Rails initializer that runs before autoloading).

Parameters:

  • pattern (String, Regexp) —

    event name or glob

  • async (Boolean) (defaults to: false) —

    enqueue via call_async (requires Async plugin)

  • options (Hash) —

    e.g. queue: “low” (overrides Async default)
