How to Implement Timeout Patterns in Go

Use context.WithTimeout to create a deadline-aware context and pass it to your operations to enforce a timeout. This pattern ensures that long-running operations are cancelled automatically if they exceed the specified duration.

ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()

// Pass ctx to your function instead of context.Background()
result, err := myFunction(ctx)
if err == context.DeadlineExceeded {
    // Handle timeout
}

Timeout patterns in Go set a strict time limit for any operation, like a timer on a microwave. If the task doesn't finish before the timer goes off, it stops automatically to prevent your program from hanging. You use this whenever you need to ensure a request or process doesn't run forever.
