v2.1.0

Improvements

• Improve TypeScript types cf2297d
  • Emittery.mixin() now returns a class type that includes the emittery property and the mixed-in methods
  • The iterators from .events() and .anyEvent() now type next() and return() precisely, instead of any
  • Emittery.listenerAdded and Emittery.listenerRemoved are now accepted everywhere the runtime accepts them, like .on(), .events(), and .listenerCount()
  • .emit() without data now works on an untyped emitter
  • .bindMethods() now accepts any object, including a class instance
  • methodNames for Emittery.mixin() and .bindMethods() now only accepts real method names. A list typed as string[] needs as const or the new EmitteryMethodName type.

Fixes

• Fix async iterators hanging forever when next() is called concurrently 7157da9
• Fix a rejected event data promise causing an unhandled rejection when an iterator never reads it 7157da9
  • A rejection that is read now throws from the iteration and closes the iterator, so a for await loop cannot leave the subscription behind.
• Fix .clearListeners() with one event name ending an .events() iterator that listens to several events 7157da9
• Fix .anyEvent() yielding the internal listenerAdded and listenerRemoved events 7157da9
• Fix listenerAdded and listenerRemoved firing when nothing changed 4987e5f
  • For example, for a duplicate .on(), a repeated .off(), or .off() of a listener that was never added.
• Fix .off() with several event names stopping at the first error and leaving the rest subscribed 4987e5f
• Fix .offAny() not removing the listener when the debug logger throws 4987e5f
• Fix the unsubscribe function from .on() changing when the event name array is mutated afterwards 4987e5f
• Fix .clearListeners() removing every listener when given an invalid event name 51d4812
  • It now throws a TypeError. Only undefined means "all events".
• Fix instances created from the same debug options object sharing their debug settings 5b47694
  • The options are now copied. To toggle logging after construction, set emitter.debug.enabled instead of changing the object you passed in.
• Fix .emit() in environments without iterator helpers 4de0d10
• Fix Emittery.mixin() silently overwriting an existing property with the same name as the emittery property 3702d31

Breaking Changes

Listeners now receive a unified {name, data} object instead of raw data

All listeners (.on(), .onAny(), .once(), async iterators) now receive a single event object with name and data properties instead of the raw event data.

- emitter.on('🦄', data => {
-   console.log(data);
+ emitter.on('🦄', ({data}) => {
+   console.log(data);
  });

For .onAny():

- emitter.onAny((eventName, eventData) => {
-   console.log(eventName, eventData);
+ emitter.onAny(({name, data}) => {
+   console.log(name, data);
  });

For .once():

- const data = await emitter.once('🦄');
+ const {data} = await emitter.once('🦄');

For .events() and .anyEvent() async iterators:

- for await (const data of emitter.events('🦄')) {
+ for await (const {data} of emitter.events('🦄')) {
    console.log(data);
  }

- for await (const [eventName, eventData] of emitter.anyEvent()) {
+ for await (const {name, data} of emitter.anyEvent()) {
    …
  }

For predicates in .once():

- emitter.once('data', data => data.ok === true);
+ emitter.once('data', ({data}) => data.ok === true);

emit() now throws AggregateError instead of rejecting with a single error

When multiple listeners throw, emit() now collects all errors into an AggregateError instead of silently dropping errors after the first one. All listeners always run to completion.

  try {
    await emitter.emit('event');
  } catch (error) {
-   // error was from the first listener that threw
+   // error is an AggregateError with all listener errors in error.errors
+   console.log(error.errors);
  }

Requires Node.js 22

The minimum required Node.js version is now 22 (previously 14.16).

New Features

• init/deinit lifecycle hooks - Register setup/teardown logic that runs when the first listener subscribes and the last listener unsubscribes for a given event.
• Disposable support - Unsubscribe functions from .on() and .onAny() are now Disposable (usable with using for automatic cleanup).
• AsyncDisposable support - Async iterators from .events() and .anyEvent() are now AsyncDisposable (usable with await using).
• AbortSignal support for .events(), .anyEvent(), and .once() - Pass {signal} to cancel subscriptions externally.
• .once() options object - Accepts {predicate, signal} in addition to a plain predicate function.
• TC39 standard decorator support - Emittery.mixin() now works with both legacy and TC39 standard decorator syntax.

Bug Fixes

• emit() no longer silently drops errors from multiple listeners
• Debug logger no longer emits noise for internal meta events
• Fixed emitMetaEvent breaking async emit() overrides in subclasses
• Fixed Emittery not working when wrapped in a Proxy
• Fixed mixin decorator to work with TC39 standard decorator syntax
