What problem does it solve?

This Skill provides a comprehensive guide to writing robust, concurrent, and maintainable Go applications, addressing common pitfalls and promoting best practices.

Core Features & Use Cases

Project Structure: Learn the standard layout for Go projects (cmd, internal, pkg).
Error Handling: Implement effective error wrapping, sentinel errors, and avoid ignoring errors.
Concurrency: Utilize goroutines, channels, and errgroup for efficient parallel processing.
Context Propagation: Understand how to correctly pass request-scoped values and cancellation signals.
Testing: Employ table-driven tests and interface-based mocking for reliable unit tests.
Use Case: When developing a new microservice in Go, use this Skill to ensure proper project structure, error handling, and concurrent request processing.

Quick Start

Use the go-patterns skill to demonstrate idiomatic error handling in Go.

FAQPage Schema

What is the best way to structure a Go project for maintainable backend services?▼

Idiomatic Go error handling uses error wrapping to add context and sentinel errors for expected conditions, ensuring robust code quality and avoiding ignored errors in backend services.

How do I manage concurrency with goroutines and channels in Golang?▼

Use context propagation in Go to correctly pass request-scoped values and cancellation signals through goroutine call chains for efficient resource utilization and graceful shutdown.

How do I write effective table-driven tests in Go?▼

Write effective table-driven tests in Go by defining test cases in slices and executing them iteratively, while employing interface-based mocking for reliable and isolated unit tests.

Can I use errgroup for parallel processing without leaking goroutines?▼

Yes, you can use errgroup for parallel processing in Go because it synchronizes goroutines and propagates the first non-nil error, preventing leaks and ensuring efficient resource utilization.
