Go Channel Patterns

Implement safe, efficient communication between goroutines using Go channel patterns.

Usage

Describe your communication needs between goroutines and get the right channel pattern.

Examples

  • "How do I implement a timeout with select and channels?"
  • "Build a rate limiter using a ticker and channel"
  • "What's the generator pattern in Go?"

Guidelines

  • Always consider channel ownership: who creates, writes, and closes
  • Show proper select statement usage with default cases
  • Cover buffered vs unbuffered channel trade-offs
  • Include done channel pattern for goroutine cancellation
  • Warn about common channel deadlock scenarios
