TypeScript RPC

Open-source TypeScript projects categorized as RPC

RPC stands for Remote Procedure Call In the context of programming. In distributed computing, a remote procedure call is when a computer program causes a procedure to execute in a different address space, which is coded as if it were a normal procedure call, without the programmer explicitly coding the details for the remote interaction.

Top 23 TypeScript RPC Projects

RPC

  1. router

    🤖 A client-first, server-capable, fully type-safe router and full-stack framework for the web (React and more).

    Project mention: Share Everything Except the Route Tree: A Multi-Customer Monorepo with TanStack Router | dev.to | 2026-07-01

    And here's the problem: TanStack Router generates a routeTree.gen.ts per project, and that generated tree does not survive a package boundary. If you go looking, you find a trail of pain: #1203 (sharing route trees across packages) and #4984 (virtual routes can't resolve package aliases in a monorepo; still open, unanswered, and its author eventually gave up and switched to React Router). There's a whole genre of blog posts titled some variation of "why TanStack Router may not be the best choice for monorepos".

  4. ts-rest

    RPC-like client, contract, and server implementation for a pure REST API

    Project mention: Modern Node.js Patterns for 2025 | news.ycombinator.com | 2025-08-03

    nvm I'm dumb lol `ts-rest` does support express v5: https://github.com/ts-rest/ts-rest/pull/786. Don't listen to my misinformation above!!

    I would say this oversight was a blessing in disguise though, I really do appreciate minimizing dependencies. If I could go back in time knowing what I know now, I still would've gone down the same path.

  5. tsrpc

    A TypeScript RPC framework, with runtime type checking and serialization, support both HTTP and WebSocket. It is very suitable for website / APP / games, and absolutely comfortable to full-stack TypeScript developers.

  6. connect-es

    The TypeScript implementation of Connect: Protobuf RPC that works.

    Project mention: Protobuffers Are Wrong | news.ycombinator.com | 2025-09-05

    It used to be that there was no official TypeScript protobuf generator from Google and third-party generators sucked. Using protobufs from web browser or in nodejs was painful.

    Couple years ago Connect released very good generator for TypeScript, we use in in production and it's great:
