Routing is not just rendering a page for a path. In serious React apps, the URL carries product state: filters, tabs, pagination, selected records, redirects, and preload decisions. TanStack Router makes that state typed instead of hopeful.
TanStack Query is not just a better useEffect. It is the server-state layer of your React app. The hard part is not fetching data — it is designing keys, freshness, invalidation, pagination, and prefetching so the UI stays predictable.
Error handling is not a catch block sprinkled at the end. In a React + TanStack app, it is a product decision: what fails locally, what fails at the route level, what can retry, and what the user needs to do next.
Not a TypeScript tutorial. A focused look at the patterns that eliminate real production bugs in React + TanStack apps — typed API layers, discriminated unions for async state, route param inference, and generic components done right.
Every new React project starts with the same question: which tools? After years of watching teams assemble mismatched libraries that fight each other, I stopped choosing independently. This is the coherent stack I now use by default — and why.
