ts-rest is a TypeScript library that enables contract-first API development by allowing developers to define shared API contracts using Standard Schema validation libraries like Zod, Valibot, or Arktype. It provides type-safe client and server implementations for frameworks such as Express, NestJS, Next.js, and Fastify, ensuring strict synchronization between frontend and backend code. The tool supports automatic OpenAPI generation and maintains close adherence to HTTP fundamentals while eliminating runtime type errors.
