An in-memory Command Pipeline implementation for PHP. A command pipeline handles cross-cutting concerns in a CQRS application that works with command objects, such as validation of commands, authorization, logging, etc.

Commands are processed in a linear process. The return value of each stage is passed to the next. A stage can only prevent the next stage from being executed by throwing an exception.

The concept of the command pipeline is loosely based on the [Pipes and Filters](https://www.enterpriseintegrationpatterns.com/patterns/messaging/PipesAndFilters.html)pattern.

Features
--------

[](#features)

- Command validation
- Command authorization
- Wrapping command handling in a Doctrine database transaction
- Dispatching emitted domain events to an event bus

Installation
------------

[](#installation)

```
composer require nicwortel/command-pipeline
```

If you are using Symfony, enable the CommandPipelineBundle:

```
// config/bundles.php

return [
    // ...
    NicWortel\CommandPipeline\Bundle\CommandPipelineBundle::class => ['all' => true],
];
```

Usage
-----

[](#usage)

Fetch the `command_pipeline` service from the service container or (recommended) inject the `CommandPipeline` into your application code:

```
