emmi

WIP

Inspired by mitt, but with a few modifications. Main difference is that events are typed with an input and output field.

This enables:

• calling emit returns an Output[] value.
  • listeners can directly respond to your events
• You can listen to event replies with onReply

Other that that, should be similar to other event emitter libraries.

Listeners

Listeners can return the Output type, or simply omit returning anything. For convenience, listeners that return undefined/void will not be added to the Output[] result of an emit.

Note that async functions that return undefined (Promise<undefined>) will be returned
