Golang

Use gofmt and goimports to enforce consistent code formatting, then apply golangci-lint to catch style violations and idiomatic Go patterns. This ensures your codebase follows Effective Go conventions and passes CI checks without manual review overhead.

Organize code into a multi-package layout with a go.mod file at the root, separating concerns by package. This structure supports modular testing, clear dependencies, and aligns with Go's module system for reproducible builds and deployments.

Write test files alongside your packages using Go's built-in testing package, then run tests and benchmarks via go test. Modern tooling integrates test execution into your build pipeline, catching regressions early and documenting performance expectations.

Yes, if your project has a go.mod file and multi-package structure, you can incrementally apply gofmt, goimports, and golangci-lint rules. Start with formatting and linting, then refactor toward idiomatic patterns and explicit error handling as you maintain the code.

Go emphasizes explicit error handling—checking and returning errors at each step rather than using exceptions. This pattern, documented in Effective Go, forces clarity about failure modes and integrates naturally with Go's if err != nil convention throughout your packages.

Establish a standard project structure with go.mod, apply linting and formatting checks, write comprehensive tests, and document your packages. This foundation lets CI systems build, test, and validate your code automatically across modules before deployment.
