To keep TypeScript DTOs in sync with a Go backend, cross-reference frontend interfaces against backend definitions to verify JSON payloads and catch breaking changes early. This prevents data drift and runtime errors during development.

Validate TanStack Query invalidation logic by checking data flow integrity and verifying query keys against the updated backend API contract. This systematic verification ensures payload shapes match the modified endpoint definitions.

Yes, this contract verification approach works specifically with Next.js and Go backend workflows. It applies to development processes involving endpoint modifications, DTO updates, and interface changes to maintain strict type safety.

The best way to prevent frontend-backend data drift is to enforce strict API contract consistency by systematically verifying JSON payloads and error handling logic against backend definitions whenever database models or Go structs are updated.

Runtime errors occur after adding new fields because the corresponding TypeScript interface and UI components were not updated to handle the new data. Verifying the frontend client against the modified backend API contract resolves this.
