tanstackv0.4.5

Build a client-side React SPA for a B2B SaaS analytics product. Use TanStack Query to fetch dashboard metrics, cache them with tuned staleTime, and handle optimistic updates for user-generated reports. TanStack Router provides file-based routing with validated search params for filters and date ranges.

Create a full-stack e-commerce site using TanStack Start for SSR and server functions to securely fetch product data and handle checkout without exposing secrets. Router loaders preload product pages while Query manages cart state and mutation invalidation. Deploy to Vercel or Cloudflare with middleware for auth and geolocation.

Build an AI chat interface that streams tokens from an LLM or SSE endpoint using TanStack Query's experimental streamedQuery. Use Router for session-based routing and search params to persist conversation history. Combine with server functions on TanStack Start to proxy API keys securely.

Develop an internal tool for managing users, orders, and inventory with infinite scrolling lists powered by useInfiniteQuery and virtual scrolling. TanStack Router handles nested, pathless layouts with type-safe navigation and preloading. Query manages mutations with optimistic updates and cache invalidation across related entities.

Build a headless CMS frontend where editors create and publish articles with optimistic UI and rollback on failure. Use TanStack Query for caching article lists and details, with hierarchical query keys for filtering by category and status. TanStack Router provides route loaders for SEO-friendly SSR on public pages.

Offer the built application as a hosted, multi-tenant SaaS product with tiered plans based on usage limits (e.g., number of queries, seats, or data retention). TanStack's caching and SSR capabilities reduce infrastructure costs while delivering fast, type-safe experiences that justify premium pricing.

Release the core integration layer (e.g., a starter kit or component library) as open source under MIT, and monetize advanced features like SSO, audit logs, team management, or priority support. Leverage TanStack's type safety and modularity to build a robust open-source foundation that attracts contributors and enterprise leads.

Use the skill to deliver bespoke React applications for clients across industries, from e-commerce to fintech. Charge for discovery, implementation, and ongoing maintenance, with TanStack Start enabling full-stack delivery including SSR, server functions, and deployment to Cloudflare/Vercel.
