📱 One small React Native habit that saves a lot of debugging time: keep API state and UI state separate. I see too many apps where loading flags, form state, server data, filters, modal state, and user session all live in one giant store. It works at first. Then every screen starts depending on everything. A cleaner approach: • server data stays close to the API layer • local UI state stays local • global state is only for truly shared data • derived values are computed, not duplicated • cache invalidation is planned early The result is less re-rendering, fewer side effects, and much easier debugging. React Native gets much easier when state has clear ownership. ⚙️
