About:
errcheck is a static analysis tool for Go that identifies calls to functions which return errors that are not being checked. It helps developers prevent bugs and potential panics by ensuring that error return values are explicitly handled.
Key Features:
  • Static analysis of Go source code
  • Detects unchecked error returns
  • Configurable exclusion of specific identifiers
  • Integrates with CI/CD pipelines
Use Cases:
  • Enforcing error handling discipline in Go projects
  • Code review automation to catch missing error checks
  • Preventing runtime panics by identifying unhandled errors
Alternatives:
  • staticcheck – Broader static analysis suite that includes error checking among many other rules
  • golangci-lint – Meta-linter that aggregates multiple tools including errcheck
