PHPMessageBus/messagebus

This system is a command, event, and query bus framework that facilitates the execution of handlers through a middleware pipeline. It supports dependency injection by resolving handlers via PSR-11 and Symfony containers, while also ensuring correct behavior for edge cases like single-middleware chains.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 4 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit b95346c93b — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
