SummarySeparate an abstraction from its implementation so the two can vary independently.——
IntentDecouple abstractions from implementations so they can evolve independently.Define an object that encapsulates communication between a set of objects, keeping them from referring to each other directly.Encapsulate a family of algorithms or behaviors behind a common contract so they can be selected and swapped cleanly.
Decision factors
ProblemWhen an abstraction is tightly coupled to its implementation, changing one side forces changes in the other and makes the system harder to evolve.Multiple objects need to coordinate behavior, but direct references between them create tight coupling and complex dependencies.A system needs to switch between interchangeable behaviors without hardcoding branching logic everywhere.
Tradeoffs
  • Adds an extra layer of indirection.
  • Can increase the number of moving parts.
  • Makes abstractions and implementations easier to evolve independently.
  • The mediator can become large and complex if it takes on too much coordination logic.
  • Centralizing behavior can make the mediator a single point of failure if it is poorly designed.
  • Adds more moving parts than a direct conditional approach
  • Works best when behavior variations are real and likely to grow

Integration notesBridge is useful when you want one stable abstraction while swapping implementations for providers, environments, or device targets.Mediator is useful for chat systems, form coordination, workflow orchestration, and any domain where many components must collaborate without knowing about each other.Strategies can cross codebases through shared contracts, API selection rules, or runtime configuration.
