How to create an error page in AEM React SPA as like WKND SITE ERROR PAGE 

I tried with A Community Blog but still unable to create the error page in React SPA

I need to show an error page without changing the URL just like WKND SITE ERROR PAGE when resource not found.

Please suggest me a solution to handle this issue.
