@johanblumenberg/eventemitter-async

Promise based async drop-in replacement for EventEmitter

API

Follows the API specified by https://nodejs.org/api/events.html#events_class_eventemitter

If no asynchronous listeners are added, it works exactly the same as EventEmitter.

If asynchronous listeners are added, those will be executed asynchronously before the next listener is executed. This holds both when emitting events using emitAsync() and using emit().

An asynchronous event listener is any listener that returns a Promise.

Additions

emitAsync(event: string, ...args: any[]): Promise<boolean>

Does the same as EventEmitter.emit(), but returns a Promise that is resolved once all event listeners are executed.
