TANSTACK
DATA
WITHOUT UI FRICTION

With TanStack Query and TanStack Table we build interfaces that handle large data sets confidently – including pagination, filters and optimistic updates.

Stage image

We areTanStackprofessionals

We connect TanStack with backends and design systems so teams get consistent patterns for server state and tables.

  • Cache strategies, invalidation and background refetch
  • Virtualisation, sorting and bulk actions in tables
  • Error states, retry and near-offline UX
  • TypeScript typing along API contracts

TanStack Query: server state as a product

Stale-while-revalidate, deduplicated requests and focused invalidation: users see data quickly while fresh responses arrive in the background.

TanStack Table: scaling complex tables

Column pipelines, filters, sorting and row selection: we build admin interfaces that stay usable even with tens of thousands of rows.

Optimistic updates & error paths

Mutating actions feel instant; rollback and retry keep data consistent when the backend hesitates or fails.

Framework-agnostic core

TanStack libraries are lightweight and combinable – whether Next.js, Remix or plain React: patterns stay viable across platform changes.
