Request validation

Choose the best answer for: input validation
Options
  1. 1Validate on server (never trust client); use schema libraries
  2. 2No validation, since a well-typed client is trusted to send valid data
  3. 3Trust everything, because the client already validates input first
  4. 4Client only, using browser-side checks as the only gate for the data
