Zustand

Client-state store

FreeLibraries & build toolingzustand.docs.pmnd.rs

What it is

A minimal global state store, v5, in roughly 1KB. You create a store with a plain function, then read it with a hook that re-renders only the components using the slice that changed. No providers, no reducers, no boilerplate.

Why it earns a slot

The default answer once prop-drilling gets painful and Context re-renders everything. Ten lines replace a whole Redux setup, and it pairs cleanly with TanStack Query handling the server half.

Know before you commit

No built-in structure, so large stores drift into a junk drawer. Selectors matter: subscribing to the whole store re-renders on every change.
