Go Patterns

A collection of design & application patterns for Go language.

Creational Patterns

Pattern	Description	Status
Factory	Provides an interface for creating families of releated objects	✔
Abstract Factory	Provides an interface for creating families of releated objects	✔
Singleton	Restricts instantiation of a type to one object	✔
Builder	Builds a complex object using simple objects	✔
Prototype	Instantiates and maintains a group of objects instances of the same type	✔

Pattern	Description	Status
Adapter		✔
Bridge	Decouples an interface from its implementation so that the two can vary independently	✔
Filter		✔
Composite	Encapsulates and provides access to a number of different objects	✔
Decorator	Adds behavior to an object, statically or dynamically	✔
Facade	Uses one type as an API to a number of others	✔
Flyweight	Reuses existing instances of objects with similar/identical state to minimize resource usage	✔
Proxy	Provides a surrogate for an object to control it's actions	✔

Pattern	Description	Status
Chain of Responsibility	Avoids coupling a sender to receiver by giving more than object a chance to handle the request	✔
Command	Bundles a command and arguments to call later	✔
Interpreter	interpreter	✔
Mediator	Connects objects and acts as a proxy	✔
Memento	Generate an opaque token that can be used to go back to a previous state	✔
Observer	Provide a callback for notification of events/changes to data	✔
State	Encapsulates varying behavior for the same object based on its internal state	✔
Strategy	Enables an algorithm's behavior to be selected at runtime	✔
Template	Defines a skeleton class which defers some methods to subclasses	✔
Visitor	Separates an algorithm from an object on which it operates	✔
