SummarySeparate an abstraction from its implementation so the two can vary independently.Wrap an object with other objects that implement the same contract so responsibilities can be layered dynamically.—
IntentDecouple abstractions from implementations so they can evolve independently.Wrap an object with other objects that implement the same contract so responsibilities can be layered dynamically.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.A system needs to add optional behaviors to an object without creating many subclasses for every feature combination.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.
  • Can introduce many small wrapper classes that are harder to trace in debugging.
  • Ordering of decorators matters, so composition needs to be deliberate.
  • Keeps responsibilities modular and easy to combine.
  • 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.Decorators work well for cross-cutting concerns such as logging, retry, caching, compression, and telemetry because each layer keeps the same interface while adding one concern.Strategies can cross codebases through shared contracts, API selection rules, or runtime configuration.
