Deeply nested children

There may be a case where you might want to hide the parent component if one of it's nested descendant compoenent has no children.

In this case, you can use the child attribute from useHideIfNoChildren:

import * as React from 'react';
import { useHideIfNoChildren } from 'use-hide-if-no-children';

const App = () => {
  const hideIfNoChildren = useHideIfNoChildren();

  return (
    <div 
      {...hideIfNoChildren.parent} 
      style={{ backgroundColor: 'pink', padding: '1rem', display: 'flex' }}
    >
      <h1>Here are your children!</h1>
      <div {...hideIfNoChildren.child}>
        {/* if there are 0 nodes here, then the parent component will be hidden. */}
      </div>
    </div>
  );
};
