You Might Not Need State

Anti-patterns to detect

1. Derived state stored in useState: If a value can be computed from props, other state, or query data, compute it inline during render instead of storing it in state.
2. Server state copied into useState: Never useState + useEffect to sync React Query data into local state. Use query data directly. The only exception is forms where users edit server data.
3. Props mirrored into state: Never useState(prop) + useEffect(() => setState(prop)). Use the prop directly, or use a key to reset component state.
4. Chained useEffect state updates: Never chain Effects that set state to trigger other Effects. Calculate all derived values in the event handler or inline during render.
5. Storing objects when an ID suffices: Store selectedId not a copy of the selected object. Derive the object: items.find(i => i.id === selectedId).
6. State that duplicates Zustand or React Query: If the data already lives in a store or query cache, don't create a parallel useState.
