What is the Zod Orval fullstack TypeScript workflow?

Backend defines Zod schemas for data shapes, generates OpenAPI JSON automatically. Frontend uses Orval to codegen TypeScript types, React Query hooks, and API calls from that JSON. Single source of truth—no duplicates.

Does Orval work with React Query and custom fetch?

Absolutely. Config specifies 'react-query' client and your fetch wrapper for auth/headers. Regens keep everything typed and in sync.

Is this better than tRPC for TypeScript fullstack?

For decoupled teams, yes—no shared packages needed. tRPC shines in monorepos; this scales via OpenAPI contracts anywhere.
