Declarative config objects can replace tangled useEffect hooks in complex React forms

Enterprise React applications commonly rely on chains of useEffect hooks to manage interdependent form fields, a pattern that becomes difficult to maintain as forms grow beyond 30 or 40 fields. A developer writing for DEV Community argues this imperative approach leads to fragile dependency chains, debugging nightmares, and cascading state updates that can cause infinite loops. Drawing inspiration from an older XML-driven UI framework, the author proposes describing field relationships in declarative configuration objects instead of writing imperative effect code. This approach shifts form logic from scattered useEffect calls into structured, readable config that a central handler processes automatically. The article uses pharmaceutical submission forms as a worked example, though the author notes the pattern applies equally to e-commerce, finance, and other domains with complex conditional field logic.
