tRPC

End-to-end typesafe APIs made easy

Star

Server/client exampleThe client doesn't import any code from the
server, only a single TypeScript type. The import type declaration is
fully erased at runtime. tRPC transforms this type into a fully
typesafe client.

Get Started

[?]  Automatic typesafety

Automatic typesafety & autocompletion inferred from your API-paths,
their input data, & outputs.

  Light & Snappy DX

No code generation, run-time bloat, or build pipeline. Zero
dependencies & a tiny client-side footprint.

  Add to existing brownfield project

Easy to add to your existing brownfield project with adapters for
Connect/Express/Next.js.

 1. @trpc/client depends on some babel runtime helpers + that a fetch
    () polyfill/ponyfill is used if the browser doesn't support it.
    @trpc/react is built on top of react-query.
