useRecoilBridgeAcrossReactRoots()

A hook to help with bridging Recoil state with a nested React root and renderer.

function useRecoilBridgeAcrossReactRoots_UNSTABLE():
  React.AbstractComponent<{children: React.Node}>;

If a nested React root is created with ReactDOM.render(), or a nested custom renderer is used, React will not propagate context state to the child root. This hook is useful if you would like to "bridge" and share Recoil state with a nested React root. The hook returns a React component which you can use instead of <RecoilRoot> in your nested React root to share the same consistent Recoil store state. As with any state sharing across React roots, changes may not be perfectly synchronized in all cases.

Example

function Bridge() {
  const RecoilBridge = useRecoilBridgeAcrossReactRoots_UNSTABLE();

  return (
    <CustomRenderer>
      <RecoilBridge>
        ...
      </RecoilBridge>
    </CustomRenderer>
  );
}

function MyApp() {
  return (
    <RecoilRoot>
      ...
      <Bridge />
    </RecoilRoot>
  );
}
