FAQPage Schema

How do I handle errors properly in Go applications?▼

Go error handling uses custom error types and error wrapping to provide context. Define custom errors for specific failure modes, wrap errors with fmt.Errorf to preserve the error chain, and check errors at each step. This approach enables robust debugging and graceful failure recovery in production applications.

What concurrency patterns should I use in Go?▼

Go concurrency relies on goroutines and channels. Use goroutines for lightweight concurrent tasks, channels for safe communication between them, and errgroup for coordinating multiple goroutines with error propagation. Channel pipelines fan out work and fan in results, making concurrent processing composable and readable.

How do I structure a Go project for production use?▼

Production Go projects follow a canonical layout with clear package organization, separate cmd and internal directories, and standardized tooling integration. This structure supports scalability, testing, and team collaboration. Use gofmt and goimports for consistency, golangci-lint for code quality, and go test for validation.

What's the best way to build HTTP handlers in Go?▼

HTTP handlers should validate requests, process logic, and return proper error responses. Use Go's standard http package with middleware for cross-cutting concerns, structure handlers to propagate errors cleanly, and return meaningful status codes and error messages to clients.

Can I use goroutines and channels to build a worker pool?▼

Yes, worker pools are a standard Go concurrency pattern. Create a fixed number of goroutines that read tasks from a channel, process them, and send results back. This pattern limits resource consumption while processing many tasks efficiently, making it ideal for batch processing and service scaling.

Why should I use errgroup for concurrent tasks?▼

errgroup simplifies managing multiple goroutines by handling synchronization and error collection automatically. If any goroutine returns an error, errgroup stops remaining work and surfaces the error. This prevents silent failures in concurrent code and ensures clean shutdown on errors.
