🚀 You are looking at a pre-release of tRPC v10!

You might be looking for the main-branch which is the stable v9-version.

See our migration guide for a summary of what is changing or take a look at the v10 docs website. There is also the examples-v10-next-prisma-starter-sqlite project to try out a real project using this version.

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.

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:
