SummarySeparate an abstraction from its implementation so the two can vary independently.Construct a complex object step by step so the same construction process can create different representations.Encapsulate a request as an object so it can be invoked, queued, logged, or undone independently of the receiver that performs the work.
IntentDecouple abstractions from implementations so they can evolve independently.Separate the construction of a complex object from its final representation.Encapsulate a request as an object so it can be invoked, queued, logged, or undone independently of the receiver that performs the work.
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.Constructing complex objects directly can make required steps, optional values, and validation hard to manage.A system needs to trigger actions without tightly coupling the code that requests an operation to the code that performs it, and it may also need queuing, history, or undo support.
Tradeoffs
  • Adds an extra layer of indirection.
  • Can increase the number of moving parts.
  • Makes abstractions and implementations easier to evolve independently.
  • Adds more classes or steps to the construction process.
  • Can be overkill for simple objects.
  • Improves clarity when object construction is complex or incremental.
  • Introduces extra classes or objects for each action.
  • Can feel heavier than direct method calls when the workflow is simple.
  • Makes requests more flexible, loggable, and replayable.

Integration notesBridge is useful when you want one stable abstraction while swapping implementations for providers, environments, or device targets.Builder is most useful when construction must happen in controlled steps and the final object has many optional or ordered parts.Commands work well for UI actions, background jobs, workflow steps, and undoable operations because invokers can trigger commands without depending on receiver details.
