What problem does it solve?
TanStack Start helps you avoid stitching together separate React, routing, SSR, and server API/RPC solutions by providing a single full-stack framework with a consistent architecture.
Core Features & Use Cases
- Full-stack routing with SSR and streaming: Define routes and render on the server with streaming for better performance and responsiveness.
- Type-safe server functions (RPC): Create client-to-server functions with strong typing and optional validation for safe data access and mutations.
- Middleware and API route support: Implement cross-cutting concerns like auth/logging and expose REST-style endpoints when needed, with deployable Nitro presets.
Use case: Build an app that lists posts, fetches data via server functions, enforces auth through middleware, and streams deferred data on the dashboard so users see the critical UI immediately.
Quick Start
Ask me to scaffold a new TanStack Start application, configure SSR streaming, and create an authenticated server function that fetches and returns user data.
