Bounded Context Separation Priciple

For mudole section there are several tactiques. One important is the section alongside of Bounded Contexts (Martin Fowlder: Bounded Context)[https://martinfowler.com/bliki/BoundedContext.html].

But separation of modules always has it's up and downs:

  • Value
    • Smaller modules make it easier to cope with systems complexity
      • test code seperately
      • fewer people work on the same repo -> less merging
    • Increase consistency by reusing code instead of creating redundancy
    • enforces clearer architectur (decisions)
    • separation of code along the different development velocities border.
    • enforces architectural section
  • Cost
    • increase of systems complexity
      • Dependency Hell / transitive dependencies
      • Section requires good documentation
      • more artifacts
    • Worse Developer Experience
      • Refactoring across multiple modules is hard to handle
      • Debugging of seperate modules my be time-consuming (multiple layers)
      • some coding tools (e.g. jump to definition) do not work over multiple repositories
      • slower development roundtrip (e.g. when using repl)
    • less awarness of what co-workes are commiting/working on
    • Danger of naive projcet section
