- Composer needs much resources. Sometimes they are not available on a simple webspace.

Messaging Client
This is a simple client to publish and consumes messages from a Message Queue server.

Implemented Connectors
| Connector | URL / Documentation | Composer Package |
|---|---|---|
| Mock | docs/mock-connector.md | - |

| Redis | https://github.com/byjg/redis-queue-client | byjg/redis-queue-client |
Usage
Publish
Consume
The consume method will wait for a message and call the callback function to process the message. If there is no message in the queue, the method will wait until a message arrives.
If you want to exit the consume method, just return Message::ACK | Message::EXIT from the callback function.
Possible return values from the callback function:
Message::ACK- Acknowledge the message and remove from the queueMessage::NACK- Not acknowledge the message and remove from the queue. If the queue has a dead letter queue, the message will be sent to the dead letter queue.Message::REQUEUE- Requeue the messageMessage::EXIT- Exit the consume method
Consumer Client
You can simplify the consume method by using the ConsumerClientTrait. See more details in the docs/consumer-client-trait.md.
Connectors
The connectors are the classes responsible to connect to the message queue server and send/receive messages.
All connector have the following interface:
There is no necessary call the method getDriver() because the method publish() and consume() will call it automatically.
Use the method getDriver() only if you need to access the connection directly.
