Simple library to route a command to its handler, the interface allows you to compose buses to add capabilities. Each handler must be a `callable`.

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

[](#installation)

```
composer require innmind/command-bus
```

Example
-------

[](#example)

```
use function Innmind\CommandBus\bootstrap;
use Innmind\Immutable\Map;

class MyCommand {}

$echo = function(MyCommand $command) {
    echo 'foo';
};

$handle = bootstrap()['bus'](
    Map::of('string', 'callable')
        (MyCommand::class, $echo)
);

$handle(new MyCommand); //prints 'foo' and return null;
```
