Solving Real-World Data Fetching Challenges with Next.js and TanStack Query
Ever battled an API that dumps way more data than you actually need, causing sluggish UIs and endless network chatter? Fariz Aziz dives into a fintech case study where bloated payloads and patchy caching were the norm. He shows how swapping to a Backend-for-Frontend (BFF) pattern, combined with Next.js’s server-side rendering and API routes, slims down those payloads and batches requests more intelligently.
On the frontend side, TanStack Query becomes the secret sauce—managing server-to-client state, cutting unnecessary re-renders, and making caching bulletproof. You’ll walk away with a clear evolution path from naive fetch calls to a robust, resilient data-fetching setup that keeps your app fast, your network calls lean, and your users happy.
