This document describing how you can use symfony/messenger bundle inside this environment.
Symfony's Messenger is much powerful bundle, that supports by the symfony core team, and provides a message bus and some routing capabilities to send messages within your application and through transports such as message queues. Before using it, read the Messenger component documentation to get familiar with its concepts.
This environment is using RabbitMQ message broker software. RabbitMQ is open source message broker software (sometimes called message-oriented middleware) that implements the Advanced Message Queuing Protocol (AMQP). The RabbitMQ server is written in the Erlang programming language and is built on the Open Telecom Platform framework for clustering and failover. Client libraries to interface with the broker are available for all major programming languages.
You can use your browser in order to manage/view messages. Just open next url in your browser: http://localhost:15672. Default login - guest and password - guest (you are able to change it inside .env configuration file).
Once your messages have been routed, it will be consumed. In case any issue just make sure that program:messenger is working in supervisord. You can use make command make logs-supervisord for these needs.
Before you can send a message, you must create it first. In order to do something when your message is dispatched, you need to create a message handler. Please follow docs in order to implement it:
When activated, the management plugin provides an HTTP API at http://server-name:15672/api/ by default. Browse to that location for more information on the API. For convenience the same API reference is available from GitHub:
