Devoxx: Solving Real-World Data Fetching Challenges with Next.js and TanStack Query: A Pragmatic Case Study

Fariz Aziz walks us through a fintech data-fetching headache—huge, bloated API payloads, excessive requests, shaky caching and resilience—and how a Backend-for-Frontend pattern paired with Next.js (SSR and API routes) slims things down, cuts payload sizes and streamlines caching.

Then he layers on TanStack Query to handle client-state, minimize re-renders and boost scalability, turning a clunky multi-client API into a fast, resilient, front-end-friendly powerhouse—all backed by real-world demos and practical tips.
