[License Widget]: https://img.shields.io/badge/license-Creative%20Commons%204.0-E91E63.svg?style=flat-square [License]: http://creativecommons.org/licenses/by/4.0/ 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 | __Concurrency Patterns__: | Pattern | Description | |:-------:| ----------- | | [Scheduler](scheduler.go) | | | [Barrier](barrier.go) | | | [Producer Consumer](producer_consumer.go) | | | [Futures](future.go) | | | [Broadcast](broadcast.go) | | | [Multiplex](multiplex.go) | | | [Fan-In](fan_in.go) | | | [Generators](generator.go) | | | [Coroutines](coroutine.go) | | __Stability Patterns__: | Pattern | Description | |:-------:| ----------- | | [Bulkheads](bulkhead.go) | | | [Circuit Breaker](circuit_breaker.go) | | | [Deadline](deadline.go) | | | [Fail Fast](fail_fast.go) | | | [Handshaking](handshaking.go) | | | [Steady State](steady_state.go) | | __Profiling Patterns__: | Pattern | Description | |:-------:| ----------- | | [Timing Functions](timing.go) | Wraps a function and logs the execution | __Idioms__: | Pattern | Description | |:-------:| ----------- | | [Functional Options](functional_options.go) | Allows creating clean APIs with sane defaults and idiomatic overrides | __Anti-Patterns__: | Pattern | Description | |:-------:| ----------- | __Other Patterns__: | Pattern | Description | |:-------:| ----------- | # License [![Creative Commons
