Ryan Carniato, creator of SolidJS, and Tanner Linsley, founder of TanStack, dive into the resurgence of Remote Procedure Calls (RPC) in web development. They discuss how Solid and TanStack are shaping modern data fetching paradigms. From the evolution of SolidStart's server functions to the importance of runtime validation for RPC safety, their insights are invaluable. They also explore advanced serialization and streaming techniques that enhance performance, making RPC a key player in next-gen frameworks.

INSIGHT

Why RPC Feels Natural Again

RPC is a function-call paradigm across environments that feels like calling a local function but operates over the network.
Modern meta-frameworks made RPC natural again by co-locating server and client code and simplifying invocation.

ANECDOTE

SolidStart Origin Story

Ryan recounts building SolidStart and noticing file-based APIs felt awkward compared to Rails-style co-location.
He prototyped auto-generated actions/loaders to call server logic directly without the fetch ceremony.

INSIGHT

Compilers Make RPC Magical

The compiler/bundler transforms (Vite, Vinci) let frameworks detect server/client boundaries and generate RPC stubs automatically.
That compile-time instrumentation is a key enabler for ergonomic, typed RPC experiences.

In this episode of JavaScript Jabber, I sit down with Ryan Carniato, creator of SolidJS, and Tanner Linsley, the force behind TanStack, for a deep-dive conversation on the resurgence of Remote Procedure Calls (RPC) in modern web development. We explore why RPC is making a comeback, how frameworks like Solid, TanStack, and others are shaping the way we think about data fetching, and the technical innovations that are driving this movement forward.

From streaming and serialization to type safety and the future of client-server communication, Ryan and Tanner share their experiences, insights, and the unique challenges they’ve faced building cutting-edge tools for developers. If you’ve been curious about where RPC fits in today’s frameworks—or just love geeking out about performance, signals, and developer experience—this is one episode you won’t want to miss.
