@lucid-softworks/typed-event-emitter

A synchronous emitter whose event map defines each listener argument tuple.

import { TypedEventEmitter } from "@lucid-softworks/typed-event-emitter";

type Events = { progress: [completed: number, total: number] };
const events = new TypedEventEmitter<Events>();
events.on("progress", (completed, total) => {});

Listeners support once, explicit removal, bulk clearing, and AbortSignal.
