A curated collection of idiomatic design & application patterns for Go language.

|
__Creational Patterns__:
|
|
|
|
| Pattern | Description |
|
|
|:-------:| ----------- |
|
|
| [Abstract Factory](abstract_factory.go) | use a generic function with specific factories |
|
|
| [Borg Singleton](borg_singleton.go) | a singleton with shared-state among instances |
|
|
| [Builder](builder.go) | instead of using multiple constructors, builder object receives parameters and returns constructed objects |
|
|
| [Factory Method](factory_method.go) | delegate a specialized function/method to create instances |
|
|
| [Lazy Evaluation](lazy_evaluation.go) | lazily-evaluated property pattern in Go |
|
|
| [Object Pool](object_pool.go) | preinstantiate and maintain a group of instances of the same type |
|
|
| [Prototype](prototype.go) | use a factory and clones of a prototype for new instances (if instantiation is expensive) |
|
|
|
|
__Structural Patterns__:
|
|
|
|
| Pattern | Description |
|
|
|:-------:| ----------- |
|
|
| [Adapter](adapter.go) | adapt one interface to another using a white-list |
|
|
| [Bridge](bridge.go) | a client-provider middleman to soften interface changes |
|
|
| [Composite](composite.go) | encapsulate and provide access to a number of different objects |
|
|
| [Decorator](decorator.go) | Adds behavior to an object, statically or dynamically |
|
|
| [Facade](facade.go) | use one class as an API to a number of others |
|
|
| [Flyweight](flyweight.go) | transparently reuse existing instances of objects with similar/identical state |
|
|
| [Model View Controller](mvc.go) | model<->view<->controller (non-strict relationships) |
|
|
| [Proxy](proxy.go) | an object funnels operations to something else |
|
|
|
|
__Behavioral Patterns__:
|
|
|
|
| Pattern | Description |
|
|
|:-------:| ----------- |
|
|
| [Chain](chain.go) | apply a chain of successive handlers to try and process the data |
|
|
| [Catalog](catalog.go) | general methods will call different specialized methods based on construction parameter |
|
|
| [Chaining Method](chaining_method.go) | continue callback next object method |
|
|
| [Command](command.go) | bundle a command and arguments to call later |
|
|
| [Mediator](mediator.go) | an object that knows how to connect other objects and act as a proxy |
|
|
| [Memento](memento.go) | generate an opaque token that can be used to go back to a previous state |
|
|
| [Observer](observer.go) | provide a callback for notification of events/changes to data |
|
|
| [Publish/Subscribe](publish_subscribe.go) | Passes information to a collection of recipients who subscribed to a topic |
|
|
| [Registry](registry.go) | keep track of all subclasses of a given class |
|
|
| [Specification](specification.go) | business rules can be recombined by chaining the business rules together using boolean logic |
|
|
| [State](state.go) | logic is organized into a discrete number of potential states and the next state that can be transitioned to |
|
|
| [Strategy](strategy.go) | Encapsulates an algorithm inside a struct |
|
|
| [Template](template.go) | an object imposes a structure but takes pluggable components |
|
|
| [Visitor](visitor.go) | invoke a callback for all items of a collection |
|
|
|
|
__Synchronization Patterns__:
|
|
|
|
| Pattern | Description |
|
|
|:-------:| ----------- |
|
|
| [Lock/Mutex](mutex.go) | Enforces mutual exclusion limit on accessing a resource |
|
|
| [Read-Write Lock](read_write_lock.go) | |
|
|
| [Condition Variable](condition_variable.go) | |
|
|
| [Monitor](monitor.go) | Combination of mutex and condition patterns |
|
|
| [Semaphore](semaphore.go) | Allows controlling access to a common resource |
|
|
|
|
