tRPC

End-to-end typesafe APIs made easy

Demo

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 - reach out if you want to make a Svelte/Vue/... adapter)
• 🥃 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
