Message Bus

A domain message bus is bound to MsgPhp\Domain\DomainMessageBus. Its purpose is to dispatch any type of message object either synchronously or asynchronously.

A message object is considered domain-specific language (DSL) and can be listened for using so called "message handlers" (a PHP callable).

Command Query Responsibility Segregation

Commands are a specific type of messages, typically used for "commanding" the domain, thus describing actions to be taken.

Typically commands require exactly one "command handler" listening.


dispatch(object $message): void
