Routes

TanStack Start uses file-based routing. Every .tsx file in this directory defines a route. Do not create src/pages/, src/routes/_app/index.tsx, or app/layout.tsx — those are Next.js / Remix conventions. The only root layout is src/routes/__root.tsx.

Conventions

File	URL
index.tsx	/
about.tsx	/about
users/index.tsx	/users
users/$id.tsx	/users/:id (dynamic — bare $, no curly braces)
posts/{-$category}.tsx	/posts/:category? (optional segment)
files/$.tsx	/files/* (splat — read via _splat param, never *)
_layout.tsx	layout route (renders children via <Outlet />)
__root.tsx	app shell — wraps every page; preserve <Outlet />

routeTree.gen.ts is auto-generated. Don't edit it by hand.
