Everything you need to build irresistible applications

Building with Go

Create fast, reliable, and efficient software with Google's modern language

Why Choose Go?

โšก Lightning Fast

Compiles to native code in seconds. Near C-level performance with garbage collection.

๐Ÿ”„ Built for Concurrency

Goroutines and channels make concurrent programming simple and safe.

๐Ÿ“ฆ Single Binary

Deploy anywhere with a single executable. No runtime dependencies.

๐Ÿ› ๏ธ Simple & Productive

Minimal syntax, great tooling, and fast compile times boost productivity.

Go Best Practices

Go Idioms

  • Keep it simple and readable
  • Return early, avoid deep nesting
  • Accept interfaces, return structs
  • Handle errors explicitly

Concurrency

  • Don't communicate by sharing memory
  • Share memory by communicating
  • Use channels for coordination
  • Goroutines are cheap, use them

Error Handling

  • Check errors immediately
  • Wrap errors with context
  • Use custom error types
  • Log errors at the boundary

Performance

  • Measure before optimizing
  • Use sync.Pool for objects
  • Minimize allocations
  • Profile CPU and memory

Quick Start Templates

๐ŸŒ Web API

Pro Tips

๐Ÿ“ Project Structure

Follow standard Go project layout - cmd/, pkg/, internal/ directories

๐Ÿงช Table-Driven Tests

Use table-driven tests for comprehensive and maintainable test coverage

๐Ÿ” Go Modules

Always use Go modules for dependency management and versioning

๐Ÿš€ Goroutine Leaks

Always ensure goroutines can exit - use context for cancellation
