BusRide

A simple Message Bus implementation, based on Architecture Patterns With Python by Harry J.W. Percival And Bob Gregory, published by O’Reilly

To quote:

Commands capture intent. They express our wish for the system to do something. As a result, when they fail, the sender needs to receive error information.

…

Events capture facts about things that happened in the past. Since we don’t know who’s handling an event, senders should not care whether the receivers succeeded or failed.

• Free software: MIT

• Documentation: https://bus_ride.readthedocs.io/en/latest

Features

• Commands, Receivers, Events, Handlers, ReturnMessages*.

Note

The purpose fulfilled by the ReturnMessage class is discussed in the book as an “ugly hack,” but acceptable until you are ready to fully embrace Command-Query Responsibility Segregation, as discussed in Chapter 12. 😁

Roadmap

• not much actually

• tox to support more Python versions

• maybe some more tests

• maybe some documentation improvements if there is feedback

• fix that one thing mypy is complaining about
