This library aims to provide a way of getting Symfony Messenger up and running in a Laminas/Mezzio application with minimum fuss.

Portions of this library borrow heavily from xtreamwayz/expressive-messenger

These docs assume that you are familiar with Symfony Messenger and the conventions associated with setting up a Mezzio application.

Package Dependencies/Suggestions

Because Messenger provides Symfony cli commands to consume queues and process messages amongst other things, this package suggests laminas/laminas-cli. This Symfony CLI integration works on a convention that commands are available in your DI container configuration as a hash map under config.laminas-cli.commands using the command name as the key and the container identifier as the value. If that's not how you roll, then you'll still be able to benefit from the command factories, you'll just have to wire them up how you like. If you choose to install laminas/laminas-cli, then you'll be able to issue a vendor/bin/laminas messenger:consume [options] without much trouble.

Installation & Configuration

composer require netglue/laminas-messenger

During installation, you will be asked if you want to inject the main config provider ConfigProvider::class. This configures the 'consume' and 'debug' cli tools and factories for retry strategies and transport factories. Without further configuration, you still won't have any usable message busses, so there are 3 more config providers available:

  • FailureCommandsConfigProvider::class configures cli tools that allow you to inspect and manipulate the failure transport/queue and as such require that a failure transport is configured. Manually add this config provider to your setup if you want to configure a failure transport/queue.

  • DefaultCommandBusConfigProvider::class provides a typical setup for a single command bus retrievable from the container with the key command_bus.

  • DefaultEventBusConfigProvider::class provides a typical setup for an event bus retrievable with event_bus

None of those config providers assume anything about your transport setup so in order to get up and running, you should also see the annotated example configurations in ./docs
