Extensive documentation is available in the README, from installation, configuration, and developer guidance.

Requirements

Any actively supported version of Drupal core. All other dependencies are automatically managed by Composer.

Suggested projects

• Transports (usually you'll need one of these)
  These are required to handle messages asynchronously. Like a queue; separately from the web thread.
  • AMQP database transport — for use with RabbitMQ, Apache ActiveMQ, etc
  • Redis
  • Deprecated: Doctrine database transport — an alternative implementation for SQL, for use with Postgres, MySQL, etc. (SM is already bundled with a Drupal SQL native transport)
• Message Scheduler — Automatically sends messages (queue items) on a recurring schedule, in the same manner as cron and crontab syntax.
• Mailer
  • Symfony Mailer integration — transmit emails asynchronously; separately from the web thread. Requires a patch.
  • Symfony Mailer Lite integration — and again, transmit emails asynchronously; separately from the web thread.
• Batch Messenger — Group Symfony Messenger messages together into a collection. Expose a UI of progress of each collection. Intercept and convert Batch API calls (batch_set) to Messenger messages.
• Notifier — Provides a unified way to send email, SMS, chat messages. Integrates with Symfony Message for dispatch.
