- 01
Block navigation away from a dirty form
Use useBlocker for router navigation and browser unloads, with explicit state for a custom confirmation UI.
- 02
Build a bounded cursor Infinite Query
Use one queryKey for the full list, let server cursors drive pageParam, and bound cache and refetch cost with maxPages.
- 03
Build a route tree from files
Create issue list and detail pages, then connect file names, path params, and inferred types.
- 04
Build a safe boundary for async field validation
Reject invalid input synchronously, run async validation through built-in debouncing, and separate early feedback from final server validation.
- 05
Compose request boundaries with Middleware
Separate request middleware from Server Function middleware and compose logging, context, and security checks with next().
- 06
Configure Query SSR and streaming hydration
Create a QueryClient per SSR request, use the Router integration for dehydration and hydration, and classify blocking versus streaming queries.
- 07
Confirm identity before child routes load
Protect a route group with typed Router Context and a pathless layout beforeLoad while preserving the correct post-login destination.
- 08
Consume Query AbortSignal
Pass the queryFn signal into the request layer so cancellation stops I/O with explicit cache-revert semantics.
- 09
Contain errors in the right route
Use a global default as the safety net and route errorComponent to isolate local data or render failures.
- 10
Contain route loader and render errors
Set a Router-wide default and override errorComponent on routes that need independent recovery.
- 11
Coordinate sorting and pagination for a server-backed table
Let Table own view state and Query own remote data, using manualSorting, manualPagination, and rowCount to avoid processing only the current page.
- 12
Create a file route with a path parameter
Create /posts/$postId in a React app and read the typed postId from the route instance.
- 13
Create a server-only function
Use createServerFn to define a same-origin, type-safe server RPC.
- 14
Create an externally callable Server Route
Build a native HTTP endpoint for third-party callers with explicit status, caching, and safe responses.
- 15
Create your first Start app
Use the official CLI to create a minimal app and locate the route tree, root document, and development server.
- 16
Define a Query freshness contract
Set staleTime from data volatility and decide inactive-cache gcTime independently.
- 17
Define when data is fresh
Separate staleTime from gcTime and co-locate keys, fetchers, and time policy in shared queryOptions.
- 18
Establish a Start Middleware chain
Define request and function scopes, compose context through next(), and preserve authentication and CSRF boundaries.
- 19
Establish typed Router Context
Declare dependencies at the root and use beforeLoad to add inferred derived context to a subtree.
- 20
Implement a rollback-safe optimistic update
Cancel conflicting refetches, snapshot cache, write an immutable draft, roll back on failure, and revalidate on settlement.
- 21
Isolate and stream Query state across SSR
Use the Router SSR Query integration for dehydration, hydration, and streaming while creating an isolated cache per server request.
- 22
Keep fields, validation, and submission on one type
Build a controlled form with useForm, Field, and Subscribe, making validation timing, error display, and async submission explicit.
- 23
Keep infinite lists bounded and recoverable
Define pagination with initialPageParam, cursors, and maxPages while preserving the pages and pageParams structure.
- 24
Let the loader warm the Query cache
Router decides when navigation happens while Query owns the cache. Connect them with one shared queryOptions object.
- 25
Make optimistic updates safe to roll back
Choose UI-only pending output or a cache-level update, then handle failure and concurrency with cancellation, snapshots, rollback, and revalidation.
- 26
Model issue data as a headless table
Connect data to semantic table markup with typed column definitions, a core row model, and flexRender while retaining full styling control.
- 27
Pass dependencies through Router Context
Declare typed dependencies at the root, then use beforeLoad to add inferred context for a route subtree.
- 28
Prefetch Query from a route loader
Create a request-scoped QueryClient for SSR and reuse one queryOptions contract in the loader and useSuspenseQuery.
- 29
Propagate Query cancellation to the network
Consume the AbortSignal supplied to queryFn so obsolete fetches stop and cancellation state remains predictable.
- 30
Protect a route subtree with beforeLoad
Read typed auth context in a pathless layout, stop signed-out users before child loading, and preserve a constrained return URL.
- 31
Protect navigation away from a dirty form
Use useBlocker resolver state for accessible leave confirmation and register beforeunload only while dirty.
- 32
Put external endpoints in a Server Route
Separate application RPC from public HTTP endpoints and use a native Response to express status, body, and cache policy.
- 33
Put filters in the URL
Build shareable, refresh-safe, typed issue filters with validated search params.
- 34
Router loader or Query?
Choose Loader, Query, or both from navigation criticality and data lifecycle needs.
- 35
TanStack is not one framework
Before installing packages, build a mental map of how Start, Router, and Query divide responsibility.
- 36
Update cache from a mutation response
Use setQueryData when the write response contains the complete entity; invalidate when the correct cache cannot be derived.
- 37
Validate pagination and filter search params
Turn untrusted URL search params into stable, typed route input.
- 38
Write back from a Server Function
Validate input at the network boundary, model write state with a mutation, then immutably update Query cache from the server response.
