Step-by-step migration from Next.js App Router to TanStack Start: route definition conversion, API mapping, server function conversion from Server Actions, middleware conversion, data fetching pattern changes.
Step-by-step migration from React Router v7 to TanStack Router: route definition conversion, Link/useNavigate API differences, useSearchParams to validateSearch + useSearch, useParams with from, Outlet replacement, loader conversion, code splitting differences.

validateSearch, search param validation with Zod/Valibot/ArkType adapters, fallback(), search middlewares (retainSearchParams, stripSearchParams), custom serialization (parseSearch, stringifySearch), search param inheritance, loaderDeps for cache keys, reading and writing search params.
Non-streaming and streaming SSR, RouterClient/RouterServer, renderRouterToString/renderRouterToStream, createRequestHandler, defaultRenderHandler/defaultStreamHandler, HeadContent/Scripts components, head route option (meta/links/styles/scripts), ScriptOnce, automatic loader dehydration/hydration, memory history on server, data serialization, document head management.
Full type inference philosophy (never cast, never annotate inferred values), Register module declaration, from narrowing on hooks and Link, strict:false for shared components, getRouteApi for code-split typed access, addChildren with object syntax for TS perf, LinkProps and ValidateLinkOptions type utilities, as const satisfies pattern.
