description: Use React's hooks inside a resource, plus tap's additions.
---

Inside a resource you use React's hooks, imported from `"react"`: `useState`,
`useReducer`, `useEffect`, `useMemo`, `useCallback`, `useRef`, `useEffectEvent`,
and `use`. They behave as they do in a component and follow the same rules of
hooks, with a few [differences](/tap/docs/tap/differences-from-react).

## Composition hooks

Resources can host other resources. These hooks (from `@assistant-ui/tap`) manage
child lifecycles automatically:

- [`useResource`](/tap/docs/tap/composition#useresource) hosts a single child
- [`useResources`](/tap/docs/tap/composition#useresources) hosts a keyed list
- [`useTapRoot`](/tap/docs/tap/composition#usetaproot) exposes a child as a `{ getValue, subscribe }` boundary
