프론트엔드 회복탄력성, 모든 종속성이 실패해도 동작하도록 설계하라

As cloud dependencies become fundamental to modern frontend applications, designing systems to tolerate partial failures—rather than assuming all-or-nothing success—is critical for maintaining user experience during inevitable service disruptions. The strategic separation of core and non-core functionality, combined with intentional failure isolation and transparent error communication, shifts how frontend engineers architect resilient systems. This paradigm change directly impacts product reliability, transforming brittle designs that collapse on single API failures into distributed failure-handling patterns that keep applications partially functional.
