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.

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

• ✅  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

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
