IntentDecouple abstractions from implementations so they can evolve independently.Provide a simplified high-level interface that coordinates a complex subsystem behind a smaller and easier-to-use API.Define the skeleton of an algorithm in a base class and let subclasses override selected steps without changing the overall structure.
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 client needs to perform a recurring workflow that spans several subsystem classes, but direct coordination makes the code noisy and tightly coupled.Several classes share the same algorithm structure, but some steps need to vary between implementations.
Tradeoffs
  • Adds an extra layer of indirection.
  • Can increase the number of moving parts.
  • Makes abstractions and implementations easier to evolve independently.
  • Can become a dumping ground if boundaries are unclear.
  • May obscure useful lower-level capabilities from advanced consumers.
  • Simplifies the most common entry points for the system.
  • Relies on inheritance, which can be less flexible than composition in some designs
  • May create a deep class hierarchy if many variations are needed

Integration notesBridge is useful when you want one stable abstraction while swapping implementations for providers, environments, or device targets.Facades are useful when exposing a stable boundary over a multi-service or mixed-language backend, or when presenting a consistent UI entry point over multiple readiness checks.Template Method is useful when you have repeated workflows with a common sequence of steps, such as processing orders, generating reports, and importing data.
