Overview

Each pattern is overviewed in a separate Markdown file which contains description, structure, UML, advantages/disadvantages etc. Click on a pattern title to see more.

👮🏼 Behavioural

Design patterns that identify common communication patterns between objects and realize these patterns. By doing so, these patterns increase flexibility in carrying out this communication.

Chain of Responsibility
Strategy
Command
State
Observer
Iterator
Memento
Template Method
Mediator
Interpreter
Visitor

👷🏼 Creational

Design patterns that deal with object creation mechanisms, trying to create objects in a manner suitable to the situation.

Factory Method
Abstract Factory
Singleton
Builder
Prototype
Class Cluster

👨🏼‍🏭 Structural

Design patterns that ease the design by identifying a simple way to realize relationships between entities.

Facade
Decorator
Proxy
Adapter
Flyweight
Bridge
Composite

👨🏼‍🎓 Non-GOF

Design patterns that are not described in the GOF book.

Dependency Injection
Object Pool
Private Class Data
Delegate
Multicast Delegate
DataSource
Lazy Loading
Throttling

👨🏻‍🔬 Functional

Design patterns that come from functional programming.

Monad
Future & Promise
Factory Kit
Callback
Functor
Applicative Functor
