Install with shadcn
Experimental compatibility. This installs the real Astryx package and creates a local public re-export; it does not copy component implementation source. How compatibility works.
This install URL expires with the draft preview.bash
Usage
Combines multiple object or callback refs into one stable callback ref. Use it when a component must forward a consumer ref while also attaching internal refs. Unlike calling mergeRefs during render, the callback identity stays stable across unrelated rerenders, so React does not detach and reattach the element.

Best practices
| Guidance | Practices |
|---|---|
| Do | Use useMergedRefs when one element must receive both a forwarded ref and one or more internal refs. |
| Don't | Call mergeRefs directly in a JSX ref prop; that creates a new callback on every render and forces unnecessary detach and attach work. |
Parameters
| Param | Type | Description |
|---|---|---|
refsrequired | Array<Ref<T> | undefined> | Up to six refs that should all receive the same element. |
Returns
| Field | Type | Description |
|---|---|---|
| ref | RefCallback<T> | A merged callback ref that remains stable until an input ref changes. |
