## What it is
A curated collection of 22 classic GoF design patterns implemented in Go, organized into creational, structural, and behavioral categories. Each pattern includes example code and a brief explanation adapted to Go's type and interface semantics.

## Use cases
- learn design patterns in go
- see singleton implemented in golang
- examples of observer pattern in go
- study gof patterns with go code
- reference for builder pattern in go
- understand structural patterns like adapter and decorator in go

## When to choose
- you are learning Go and want idiomatic examples of classic design patterns
- you need a quick reference comparing creational, structural, and behavioral patterns in Go
- you prefer concise, runnable examples over lengthy theory

## When to avoid
- you need a production-ready pattern library to import into your project
- you want patterns specific to concurrency in Go (channels, goroutines patterns)
- you need actively maintained content with recent updates

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: developer-tools, tutorials, programming-languages
- platform: go, cross-platform
- tags: design-patterns, golang, go-patterns, creational-patterns, structural-patterns, behavioral-patterns, code-examples, education, algorithms
