Persisting State to localStorage
Keep your client state across page reloads by persisting it to localStorage, handling hydration safely in Next.js, and using Zustand's persist middleware.
Why Persist State?
By default, React state vanishes on reload. Persistence saves data like theme, cart contents, or draft text to the browser so it survives refreshes and revisits.
Meet localStorage
localStorage is a browser key-value store that keeps strings indefinitely. It is synchronous and scoped to the origin.
