Solving Real-World Data Fetching Challenges with Next.js and TanStack Query

Ever feel like your frontend is drowning in massive, bloated API payloads that you don’t even need? In this talk, Fariz Aziz walks you through a fintech case study where over-fetching and resilience gaps brought performance to its knees. By adopting a Backend-for-Frontend (BFF) pattern with Next.js server-side rendering and API routes, the team trimmed down payload sizes, tightened up caching, and cut out redundant network requests.

Next up, TanStack Query swoops in to handle state management, keep client-server sync in check, and minimize unnecessary re-renders—making your app both faster and more robust. Packed with live demos and practical tips, you’ll leave armed with a clear roadmap for evolving your data-fetching strategy from “meh” to “bulletproof,” even when you don’t control the backend.
