Full-stack React framework built on TanStack Router + Vite. Client-first with opt-in server capabilities. Type-safe from routes to server functions.
Triggers: tanstack start, tanstack router, server function, createServerFn, createFileRoute, gremlin-cms, tanstack app, or any work in a TanStack Start project.
Route loaders are ISOMORPHIC — they run on BOTH server and client. This is the #1 gotcha.
Build full-stack React apps with TanStack Start — server functions, type-safe routing, loaders, middleware, SSR/streaming, and deployment patterns. Use when working on TanStack Start apps, server functions, TanStack Router, or any gremlin-cms development. Source: joelhooks/joelclaw.
