behavioural

What problem does it solve?

Behavioural design patterns address scenarios where an object's behavior varies across contexts, or where the system needs to react to events without tight coupling. They provide a structured approach to decouple responsibilities and to compose interaction chains that are easier to extend and test.

Core Features & Use Cases

• Covers all 10 GoF behavioural patterns: Chain of Responsibility, Command, Strategy, State, Observer, Memento, Mediator, Visitor, Iterator, and Template Method.
• Helps teams decide when to apply a pattern, with practical contexts such as middleware pipelines, event-driven updates, undo/redo capabilities, and complex object collaborations.
• Provides rationale and templates to reason about trade-offs, side effects, and maintenance.

Quick Start

Identify a stateful interaction in your codebase and implement the appropriate behavioural pattern with a small, replaceable component.
