tRPC

Move fast and break nothing.
End-to-end typesafe APIs made easy.

The client above is not importing any code from the server, only its type declarations.

Note

You are looking at the next-branch of tRPC which is the current work in progress representing version 11.

The functionality is stable and can be used in production, but we may do small breaking API-changes between patches until we reach 11.0.0
The packages are published with the next-tag on npm
For the list of changes made, see https://trpc.io/docs/v11/migrate-from-v10-to-v11

Intro

tRPC allows you to easily build & consume fully typesafe APIs without schemas or code generation.

Features

✅ Well-tested and production ready.
?‍♂️ Full static typesafety & autocompletion on the client, for inputs, outputs, and errors.
? Snappy DX - No code generation, run-time bloat, or build pipeline.
? Light - tRPC has zero deps and a tiny client-side footprint.
? Easy to add to your existing brownfield project.
? Batteries included - React.js/Next.js/Express.js/Fastify adapters. (But tRPC is not tied to React, and there are many community adapters for other libraries)
? Subscriptions support.
⚡️ Request batching - requests made at the same time can be automatically combined into one
? Quite a few examples in the ./examples-folder

Quickstart

There are a few examples that you can use for playing out with tRPC or bootstrapping your new project. For example, if you want a Next.js app, you can use the full-stack Next.js example:

Quick start with a full-stack Next.js example:

# yarn
yarn create next-app --example https://github.com/trpc/trpc --example-path examples/next-prisma-starter trpc-prisma-starter

# npm
npx create-next-app --example https://github.com/trpc/trpc --example-path examples/next-prisma-starter trpc-prisma-starter

# pnpm
pnpm create next-app --example https://github.com/trpc/trpc --example-path examples/next-prisma-starter trpc-prisma-starter

# bun
bunx create-next-app --example https://github.com/trpc/trpc --example-path examples/next-prisma-starter trpc-prisma-starter
