watch on portal.gitnation.org ↗https://portal.gitnation.org/contents/caching-payloads-and-other-dark-arts-a-frontend-engineers-journeysummary
Covers optimizing a fintech payments dashboard when external APIs are slow or uncontrolled by using full-stack frameworks such as Next.js to implement API handlers and proxies, building a Backend-for-Frontend to reshape large payloads, and applying caching and resilience patterns. Describes profiling bottlenecks, balancing API criticality across front- and back-end, and using FaaS/IaaS infrastructure to mitigate network constraints and improve reliability without changing source APIs.
