#observable

MobX is a signal-based reactive state management library that makes any object observable and automatically tracks which derived computations and UI components depend on which fields, re-running only what's strictly needed. It's framework-agnostic at its core but most commonly paired with React via mobx-react/mobx-react-lite.

A minimal React state management library from RisingStack built on transparent reactive proxies. You wrap state objects with `store()` and components with `view()`, then mutate state with plain JavaScript and components re-render automatically based on which store properties they read.
