End to end type safety to create and use the APIs

Define your APIs with ts-rest Router, implement them in your NestJS controllers, and use them in NextJS using type-safe TanStack queries.

shared/../router.ts


import { initContract } from '@ts-rest/core';
import { z } from 'zod';

const c = initContract();

export const contract = c.router(
    {
        getTodo: {
            method: 'GET',
            path: '/todos',
            responses: {
                200: z.object({
                    id: z.string(),
                    todoTitle: z.string(),
                    completed: z.boolean(),

                }).array(),
                400: z.object({
                    message: z.string(),
                }),
            },
            summary: 'Get all todos',
        }
    },
);

Follow these steps to add and use the API

Define your API endpoint fields like body, query, pathParams, and headers in the router function using a simple TypeScript type with the c.type helper, or use Zod objects instead. [ Docs ]
