react-code-blocks/src/hooks/use-mounted.ts

Modified Atlaskit's Code Block to support more languages (i.e graphql, reasonml, etc) and theme (i.e railscast, dracula, monokai, etc) code snippets!

import { useRef, useEffect } from 'react';

export function useIsMountedRef() {
  const isMountedRef = useRef(null);
  // @ts-ignore
  useEffect(() => {
    // @ts-ignore
    isMountedRef.current = true;
    //@ts-ignore
    return () => (isMountedRef.current = false);
  });
  return isMountedRef;
}
