tRPC

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

Demo — 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](https://trpc.io/docs/awesome-trpc#-extensions--community-add-ons) 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](./examples)-folder ## Quickstart There are a few [examples](https://trpc.io/docs/example-apps) 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:** ```sh # 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 # deno deno init --npm next-app --example https://github.com/trpc/trpc --example-path examples/next-prisma-starter trpc-prisma-starter ``` **👉 See full documentation on [tRPC.io](https://trpc.io/docs). 👈** ## Star History
