At Buoy we utilize packwerk to enable us to organize our code into packages based on domain concepts or business flows.
- Prefer creating packs to encompass business flows (i.e. Processing, Payments).
- Prefer adding pack specific models and concerns inside the pack if possible.
- Prefer setting stewards.
- Avoid creating team based packs.
- Avoid global variables.
- Avoid long parameter lists.
- Limit dependencies of an object (entities an object depends on).
- Limit an object's dependents (entities that depend on an object).
- Prefer composition over inheritance.
- Prefer small methods. Between one and five lines is best.
- Prefer small classes with a single, well-defined responsibility. When a class exceeds 100 lines, it may be doing too many things.
- Tell, don't ask.
