zf-hermes

Zend Framework module to work with Node-Hermes.

Configuration

Copy the hermes.global.php.dist to change the default Redis configuration. Default values are:

  • host = 'localhost'
  • port = 6379

Usage

Just inject the NotifierService and use publish to send a message over Redis.

// $this->notifierService is an injected NotifierService
$this->notifierService->publish($message);

$message must be an object implementing the MessageInterface.

The message interface consists of the following properties:

  • channel Redis channel to publish to message onto
  • userId Id of the user that triggered the Redis event
  • timeStamp The timestamp of when the message was created
  • payload Additional data to be sent

The notifier service sends a json encoded message consisting of the properties userId, timeStamp and payload onto Redis channel channel.

Note that the channel property is not part of the message.

Recommendations

It is recommended to use listeners to listen for events that should generate a Redis message. Although it is possible to inject the notifier service directly into another class.
