Getting the text content of a React node Fragment

Published on 2024-11-13 • Modified on 2024-11-13

This snippet shows how to get the text content of a React node Fragment. It is sometimes helpful to extract the text of the following React node <>text1</>. In this case, the React node is a Fragment with only one text child. Therefore, we can retrieve it with the following function:

---

function getTextFromSimpleFragment(node: ReactNode): string {
  if (React.isValidElement(node) && node.type === React.Fragment) {
    const children = node.props.children;
    if (typeof children === 'string') {
        return children;
    }
  }

  return 'error: simple fragment expected';
}
