✅ Decision Checklist

Before designing an API:

  • Asked user about API consumers?
  • Chosen API style for THIS context? (REST/GraphQL/tRPC)
  • Defined consistent response format?
  • Planned versioning strategy?
  • Considered authentication needs?
  • Planned rate limiting?
  • Documentation approach defined?

❌ Anti-Patterns

DON'T:

  • Default to REST for everything
  • Use verbs in REST endpoints (/getUsers)
  • Return inconsistent response formats
  • Expose internal errors to clients
  • Skip rate limiting

DO:

  • Choose API style based on context
  • Ask about client requirements
  • Document thoroughly
  • Use appropriate status codes
