🐹 Level Up Your Go Code with tmrts/go‑patterns

If you’re coding in Go, you’re probably juggling channels, interfaces, and goroutines all day. But have you checked out tmrts/go-patterns on GitHub yet? It is not my repo, but I would like to share about it as it’s a treasure trove of idiomatic Go patterns, from classic creational and structural patterns to messaging and concurrency tricks. And guess what — it’s beautifully laid out, easy to understand, and wonderfully example-driven! ⭐

🚀 What Is It, Anyway?

tmrts/go‑patterns is an open-source, curated collection of Go design patterns — grouped into categories like Creational, Structural, Behavioral, Concurrency, Messaging, Synchronization, and Stability. Think of it as a cookbook for Go devs: you pick a problem, find the recipe, and enjoy readable, Go-idiomatic code.

📚 What’s Inside? Quick Category Walkthrough

Each pattern gets a concise description and a clear implementation example:

🛠 Creational Patterns

Builder, Factory Method, Singleton, Object Pool — handy ways to instantiate and manage resources.

🏗 Structural Patterns

Decorator, Proxy — helps wrap or control access to objects cleanly.

🧠 Behavioral Patterns

Observer, Strategy — unlock flexible communication and runtime behavior tweaks (Strategy lets you swap algorithms on the fly!).

⚙️ Concurrency Patterns

Bounded Parallelism, Generators, Parallelism — ideal when scaling tasks across goroutines efficiently.

📣 Messaging Patterns

Excellent recipes for Fan-In, Fan-Out, and Publish/Subscribe — key for real-world message routing.

🎯 Why Every Go Developer Should Bookmark This

Idiomatic to Go
No monkey-patching Java patterns — these are designed for Go’s strengths, like interfaces and lightweight concurrency.
Real-World Examples
Every pattern includes copy-paste-ready code so you can try it out immediately.
Breadth & Depth
It covers a vast spectrum of tasks from thread-safe synchronization to microservices-level messaging.
Actively Maintained
It's a community favorite with 26 K+ stars and hundreds of forks.

🔧 A Peek at the Proxy Pattern

Here’s a quick look at Proxy (simplified from the repo):

type Service interface {
    DoSomething()
}

type RealService struct{}

func (r *RealService) DoSomething() { /* real work */ }

type ProxyService struct {
    real Service
}

func (p *ProxyService) DoSomething() {
    fmt.Println("👉 Proxy: Doing pre-processing")
    p.real.DoSomething()
    fmt.Println("👈 Proxy: Doing post-processing")
}

With Proxy, you’re in full control, adding behavior before and after the real call. All implemented cleanly using Go’s interfaces.

💡 Best Practices Straight from Reddit

Go experts urge caution — don’t overuse patterns imported from OOP languages. The beauty of Go lies in its simplicity, composition, and preference for small, direct code blocks. That’s why tmrts/go-patterns stands out — it focuses on patterns that feel natural in Go instead of stretching abstractions.

📝 Final Verdict

tmrts/go-patterns isn’t just a collection — it’s a roadmap for writing cleaner, more idiomatic Go. Whether you’re a junior dev learning interfaces and concurrency or a senior engineer looking to improve best practices, this repo is a goldmine. Bookmark it, explore it, and apply it — one pattern at a time. 🧩

Keep coding clean, stay Go-riffic! 🐹✨
