An end-to-end guide to combining tRPC, TanStack Query, TanStack Router, and tanstack-fetch in a modern TypeScript application.

Modern TypeScript applications need more than a convenient way to fetch data. They need reliable API contracts, predictable caching, route-aware data loading, and a clean separation between HTTP transport and server state.

That is where this stack becomes interesting:

tRPC provides end-to-end type safety between your server and client.

tanstack-fetch handles HTTP transport, request configuration, and reusable networking behavior.

TanStack Query manages caching, query state, and background refetching.

TanStack Router coordinates navigation and route-level data loading.

Instead of implementing these concerns independently, we can combine them into a single, consistent data-fetching architecture.

In this tutorial, we'll build a practical example using a post.list procedure.
