Introduction

ts-rest offers a simple way to define a contract for your API, which can be both consumed and implemented by your application, giving you end to end type safety without the hassle or code generation.

Features

End-to-end type safety 🛟
RPC-like client side API ⚡️
Small Bundle Size 📉
No Code Generation 🏃‍♀️
Zod support for runtime validation 🔒
Full optional OpenAPI integration 📝

Super Simple Example

Easily define your API contract somewhere shared

const contract = c.contract({
  getPosts: {
    method: 'GET',
    path: '/posts',
    query: z.object({
      skip: z.number(),
      take: z.number(),
    }), // <-- Zod schema
    responses: {
      200: c.type<Post[]>(), // <-- OR normal TS types
    },
    headers: z.object({
      'x-pagination-page': z.coerce.number().optional(),
    }),
  },
});

Fulfill the contract on your server, with a type-safe router:

const router = s.router(contract, {
  getPosts: async ({ params: { id } }) => {
    return {
      status: 200,
      body: prisma.post.findUnique({ where: { id } }),
    };
  },
});

Consume the api on the client with a RPC-like interface:

const result = await client.getPosts({
  headers: { 'x-pagination-page': 1 },
  query: { skip: 0, take: 10 },
  // ^-- Fully typed!
});

Quickstart

Create a contract, implement it on your server then consume it in your client. Incrementally adopt, trial it with your team, then get shipping faster.
