README

A command/query message bus for Mezzio and other PSR-11 based applications. Messages (commands or queries) are dispatched through a configurable middleware pipeline to their mapped handler, and a result flows back out through that same pipeline.

Installation

composer require webware/message-bus

Registers itself as a Laminas/Mezzio config provider (Webware\MessageBus\ConfigProvider) via composer's extra.laminas.config-provider.

Acknowledgments

The middleware pipeline design in this package is directly inspired by, and mirrors the mechanics of, the PSR-15-style pipeline used in mezzio/mezzio.

This package was built for the Laminas/Mezzio ecosystem and its users, and that debt is gladly owed, credit belongs with the Laminas/Mezzio maintainers and contributors for the original design. See mezzio/mezzio and its LICENSE (BSD-3-Clause) for the source of that inspiration.
