Loader footguns and server function boundaries

Jack Harrington sits down with Tanner Linsley to talk about the evolution of TanStack and where it’s headed next. They explore how early projects like React Query and React Table influenced the headless philosophy behind TanStack Router, why virtualized lists matter at scale, and what makes forms in React so challenging. Tanner breaks down TanStack Start and its client-first approach to SSR, routing, and data loading, and shares his perspective on React Server Components, modern authentication tradeoffs, and composable tooling. The episode wraps with a look at TanStack’s roadmap and what it takes to sustainably maintain open source at scale.
