Introduction
React state management has evolved. Today the most popular options are Zustand, Jotai, and Signals. Each with its own philosophy and ideal use cases.
Zustand: the simple approach
Zustand offers a global store with a minimal API. No providers needed. Ideal for global shared state like user, cart, or preferences.
Jotai: atomic atoms
Jotai uses atoms as state units. Each atom is independent and only components that use it re-render. Perfect for granular state.
Signals: fine-grained reactivity
Signals, popularized by SolidJS and Preact, offer value-level reactivity. Only the specific element updates, not the entire component.
Performance Comparison
Jotai and Signals offer better performance in components with frequent updates. Zustand is simpler but can cause unnecessary re-renders if not used well.
When to choose which
Use Zustand for simple global state, Jotai for granular shared state, and Signals for frequent UI updates.
Conclusion
There's no one-size-fits-all solution for React state. At Vynta, we evaluate each case and choose the right tool for the project's needs.
