Incrementally adoptable RPC-like client and server helpers for a magical end to end typed experience 🪄
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.
Easily define your API contract somewhere shared
const contract = c.router({
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!
});
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.
