A Go package that represents a list of error values as a single error, with human-readable formatting and utilities like Append, Flatten, Prefix, and a concurrent Group pattern. It is now in maintenance mode since Go 1.20's errors.Join covers basic aggregation.
Use cases
- combine multiple errors into one return value in Go
- collect errors from concurrent goroutines
- format a list of errors readably
- append errors while iterating over operations
- flatten nested error lists
When to choose
- you need custom error formatting or Prefix/Flatten helpers
- you need concurrent error collection via Group
- you're maintaining an existing codebase already using it
When to avoid
- starting a new Go project that only needs basic error joining (use errors.Join)
- you only need the first error from concurrent tasks (use errgroup)
