errcheck is a static analysis tool for Go that finds silently ignored error return values. It can be run as a CLI or integrated via the go/analysis API.
Use cases
- find unchecked errors in go code
- lint go projects for ignored error returns
- enforce error handling in ci
- detect blank identifier error assignments
- check ignored type assertions in go
When to choose
- you want a focused, fast tool specifically for unchecked errors in Go
- you need go/analysis integration for custom tooling
- you want configurable exclusions for known-safe functions
When to avoid
- you need deeper analysis of assigned-but-unused errors (use staticcheck)
- you are not working in Go
