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
- 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. 😁
- 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
