TypeScript interfaces are the foundation of type-safe development. They catch errors at compile time, provide excellent IDE autocomplete, and serve as documentation for your data structures.
Benefits of Type-Safe API Responses:
- Catch property access errors before runtime
- Get intelligent autocomplete in your IDE
- Document data structures automatically
- Refactor with confidence using "Find All References"
- Reduce bugs from typos and incorrect data access
💡 Pro Tips
- •Start with TypeScript + Zod — Generate both to get compile-time AND runtime safety.
- •Use meaningful root names — "UserResponse" or "ProductList" are better than "ApiResponse".
- •Regenerate when APIs change — Just paste the new response and regenerate. Much faster than manual updates.
- •Review Prisma models — The generator makes best-effort guesses for relations. You may need to adjust for your specific database design.
