What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
A tiny (108 bytes) event emitter library for JavaScript with only `on` and `emit` methods. It supports typed events via TypeScript and returns unbind functions from listeners.
Use cases
- add a lightweight pub/sub event system to a JavaScript app
- emit and subscribe to custom events in a TypeScript project
- mix event emitter behavior into a class
- replace Node.js EventEmitter in a browser bundle to save bytes
- unbind event listeners without keeping callback references
When to choose
- you need a minimal, dependency-free event emitter for browser or ES module code
- bundle size is critical and you only need on/emit
- you want typed events with TypeScript
When to avoid
- you need Node.js EventEmitter compatibility like once, removeListener, or max listeners
- you need wildcard events, namespaces, or async listeners
- you need a full-featured event bus with aliases
