## What it is
mobx-react provides React bindings for the MobX state management library, exporting the `observer` higher-order component/decorator and utilities like Provider/inject and disposeOnUnmount. It supports both function and class-based React components (and React Native), complementing the lighter mobx-react-lite package.

## Use cases
- make react components re-render when mobx observables change
- connect mobx stores to react class components
- use observer decorator with react and react native
- pass stores to components with provider and inject
- automatically dispose reactions when class components unmount
- fine-grained reactive rendering without manual memoization

## When to choose
- you use MobX for state management in a React or React Native app
- you need class component support or Provider/inject that mobx-react-lite lacks
- you want automatic, minimal re-renders driven by observable state

## When to avoid
- you only use function components and hooks - prefer mobx-react-lite
- you use Redux, Zustand, or another state library
- your project does not use React

## Facets
- artifact type: library
- maturity: active
- function: state-management, frontend-framework, ui-components
- domain: frontend, web-development
- platform: cross-platform
