I created the build of a MERN Stack
application using the npm run build
command, then I ran this built application on my default browser (Microsoft Edge) using the npm start
command. I then installed the react devtools
extension for Edge
from Chrome
. But when I enable react devtools
on my react app, it does not activate and I get the message This page doesn’t appear to be using React.
If this seems wrong, follow the troubleshooting instructions. I don't understand why I get this error because my application is entirely designed in react on the frontend side. I don't know if it's because I got the wrong server start command .
You can try the following solution. In Edge, right click on React devtools, go to Manage extensions, and select "Allow access to file URLs". Also, it has been reported that a re-installation of react devtools and a restart of browser may help. By the way, react devtools is available in Microsoft Edge Add-ons, so you can just install it in Edge (since you said you installed it from Chrome).
