Go Concurrency Patterns

Master Go's concurrency primitives and implement proven patterns for concurrent applications.

Usage

Describe your concurrency needs or share code for guidance on goroutines, channels, and patterns.

Examples

  • "Implement a worker pool with goroutines and channels"
  • "How do I properly cancel goroutines with context?"
  • "Build a fan-out/fan-in pipeline in Go"

Guidelines

  • Always handle goroutine lifecycle and cleanup
  • Show proper channel usage: buffered vs unbuffered
  • Cover context-based cancellation and timeout patterns
  • Include sync package primitives: WaitGroup, Mutex, Once
  • Warn about common pitfalls: goroutine leaks, race conditions
