## What it is
Broadway is a PHP library providing infrastructure and testing helpers for building CQRS and event-sourced applications. It offers loosely coupled components such as command handling, domain events, event dispatching, and read-model projections that can be combined for a full CQRS/ES experience.

## Use cases
- build a CQRS application in PHP
- implement event sourcing for my domain model
- create read models with projectors from domain events
- dispatch commands through a command bus
- test event-sourced aggregates
- add an audit trail to command handling

## When to choose
- you are building a PHP application with CQRS and/or event sourcing architecture
- you want loosely coupled components you can adopt incrementally
- you need testing helpers for event-sourced domain code

## When to avoid
- you want a full-stack framework rather than infrastructure helpers
- your project does not use CQRS or event sourcing patterns
- you are not working in PHP

## Facets
- artifact type: library
- maturity: active
- function: middleware, testing, message-queue
- domain: backend, web-development, developer-tools, apis
- platform: php, cli
- tags: cqrs, event-sourcing, php, ddd, command-bus, read-models, projectors, saga
