Why do you need runtime validation if you already use TypeScript?
Answer
TypeScript types don’t exist at runtime.
APIs and user input can still be invalid. Runtime validation ensures:
- Safe parsing of untrusted data
- Better error messages
- Consistent schemas between client and server
Use schema validators to validate requests/responses and keep types in sync via inference or codegen.
