Comparison with mobx-react-lite

mobx-solid targets SolidJS the way mobx-react-lite targets React, but the integration model differs because the UI libraries differ.

Feature	mobx-react-lite	mobx-solid
Component model	Re-render entire component	Fine-grained DOM updates
Bridge	React useSyncExternalStore	SolidJS enableExternalSource
Wrappers	observer required	Not needed after enableObservableTracking()
Local store	useLocalObservable	Plain MobX observable / makeAutoObservable

Practical differences

• No observer: after the one-time enableObservableTracking() call, components can read MobX state in JSX without wrapping.
• Fine-grained updates: Solid patches only the reactive sinks that depend on changed data, instead of re-running the whole component function for every update.
• Stores: create stores with normal MobX APIs; there is no Solid-specific local-store hook.

When to choose which

• Use mobx-react-lite in React apps.
• Use mobx-solid in SolidJS apps when you want MobX as the state layer and Solid as the view layer.
