Click any node to trigger a state dispatchNodes highlighted in green are directly updated. In Context mode, all 150 nodes re-render on every click; in Zustand/Redux mode, only the target node executes.
State Engine Trade-Off Matrix
Deep architectural analysis of when and why to adopt each state engine in production.
| Engine | Reactivity Model | Bundle Cost | Re-render Cost | Recommended Use Case |
|---|---|---|---|---|
| Zustand | Atomic Selectors | ~1.2 kb | Minimal (1x) | Modern SPAs, fast interactive UI, component stores |
| Redux Toolkit | Normalized Slice | ~12 kb | Low (1x with selector) | Enterprise apps, strict action audit trails, time-travel |
| React Context | Full Tree Provider | 0 kb | Severe (Nx cascade) | Infrequent global values (Theme, Locale, Current User) |
| Signals | Fine-Grained DOM Sub | ~2 kb | Zero (Bypasses VDOM) | High-frequency canvas nodes, audio visualizers, charts |
