New Go Project

mkdir my-project
cd my-project
vx go mod init github.com/user/my-project

Web Server with Gin

vx go mod init myserver
vx go get github.com/gin-gonic/gin
# Create main.go
vx go run .

CLI Tool with Cobra

vx go mod init mycli
vx go get github.com/spf13/cobra
# Create main.go
vx go build -o mycli

Cross-Compilation

# Linux
GOOS=linux GOARCH=amd64 vx go build -o app-linux

# Windows
GOOS=windows GOARCH=amd64 vx go build -o app.exe

# macOS
GOOS=darwin GOARCH=amd64 vx go build -o app-mac

Environment Variables

Go-specific environment variables work as expected:

GOPROXY=direct vx go get github.com/user/repo
CGO_ENABLED=0 vx go build -o app

Tips

1. Use go mod tidy: Keep dependencies clean
2. Pin Go version: Ensure team uses same version
3. Use golangci-lint: Comprehensive linting
