README

This package offers Symfony Messenger's sync:// transport a different approach:

• Messages are handled synchronously, like in sync:// transport ✅

But:

• In case of failure (handler produces an exception), messages can be retried (whereas original sync:// throws the exception and crashes) 👉
• When max retries have been reached, messages can fall into the failure_transport ☝️

This way, safe-sync:// can be used as a drop-in replacement of any asynchronous transport, following the same logic (except messages are now processed synchronously). 👍

Whenever an exception is thrown during message handling, it is caught by the transport, which applies the rules you defined within your messenger.yaml.

Installation

composer require bentools/safe-sync-transport

Usage

Example:

        retry_strategy:
          max_retries: 3
