mobx-react-lite is a lightweight (1.5kB gzipped) set of React bindings for MobX, supporting functional components via Hooks (React 16.8+). It provides the observer higher-order component, an <Observer> component, and useLocalObservable to automatically track and re-render components when observables they use change.

Use cases

• connect React function components to MobX observable state
• re-render components only when observables they read change
• create local observable state inside a component with hooks
• use MobX state management without class component support
• replace mobx-react with a smaller, faster binding for hooks-based apps
• observe a small region of a component render with <Observer>

When to choose

• your app uses only React function components with hooks
• you want minimal bundle size and fast reactive rendering with MobX
• you prefer useContext over Provider/inject for dependency injection
• you need fine-grained automatic re-render tracking of observable state

When to avoid

• you need class component support - use mobx-react instead
• you rely on Provider/inject APIs from mobx-react
• you target very old browsers without Proxy support and use MobX 6
• you want automatic observation via build tooling - consider mobx-react-observer plugin
