## What it is
Événement is a very simple event dispatching library for PHP, inspired by Node.js's EventEmitter API. It lets you register listeners, remove them, and emit events with a minimal, concise API.

## Use cases
- add an event emitter to a PHP application
- dispatch custom events and notify listeners
- decouple components with a pub/sub pattern
- hook into lifecycle events like user.created
- implement observer pattern in PHP

## When to choose
- you need a lightweight, dependency-free event system in PHP
- you want a Node.js-style EventEmitter API
- you need simple on/emit/removeListener semantics

## When to avoid
- you need advanced features like event subscribers, priorities, or propagation stopping (use Symfony EventDispatcher)
- you need asynchronous or queued event processing
- you need PSR-14 compliant event dispatching

## Facets
- artifact type: library
- maturity: stable
- function: middleware
- domain: developer-tools, web-development
- platform: php
- tags: event-emitter, event-dispatching, pubsub, observer-pattern
