# Go Toolchain Common commands for Go projects. ## Build & run ```bash go build ./... go run . go run cmd/server/main.go ``` ## Testing ```bash go test ./... go test -v ./... go test -race ./... go test -cover ./... go test -coverprofile=coverage.out ./... && go tool cover -html=coverage.out -o coverage.html go test ./pkg/api/ -run TestLogin -v ``` ## Benchmarks ```bash go test -bench=. -benchmem ./... ``` ## Linting ```bash # golangci-lint (recommended) golangci-lint run ./... # Built-in go vet ./... ``` ## Formatting ```bash gofmt -w . goimports -w . ``` ## Module management ```bash go mod init mymodule go mod tidy go mod download go get github.com/pkg/errors@latest go list -m all # List all dependencies go list -m -u all # Check for updates ``` ## Build for different platforms ```bash GOOS=linux GOARCH=amd64 go build -o bin/app-linux ./cmd/server GOOS=darwin GOARCH=arm64 go build -o bin/app-darwin ./cmd/server ``` ## Debugging ```bash # Delve debugger dlv debug ./cmd/server dlv test ./pkg/api/ ``` ## Generate ```bash go generate ./... ``` ## Notes - Go projects use `go.mod` for module definition and dependency management. - Use `./...` to target all packages recursively. - `go vet` catches common mistakes; `golangci-lint` is more comprehensive.
