Go Web Frameworks interview question · Most asked
Do you need a web framework in Go? What does Go 1.22's ServeMux provide?
Summary
Often not. Since Go 1.22, http.ServeMux matches methods and path wildcards ("GET /books/{id}", read with r.PathValue), returns 405 for wrong methods, and prefers more specific patterns.
Longer Answer
Frameworks still add route groups, request binding and validation, centralised error handling and helper APIs. Small services and libraries often stay on the standard library for zero dependencies and long-term stability; larger APIs may prefer Chi, Gin or Echo for ergonomics.
Key Points
- Method + wildcard routing since 1.22.
- 405 handling built in.
- Frameworks add groups, binding, validation, errors.
