ReactJS doesn't render in Electron


this is my code:

as you can see I have in /src/index.js that App should be included in

with id root, I have that
in /src/index.html , and /src/components/App.js should display some Electron text, but it doesn’t I don’t know where is the problem.

If you open developer tools in your electron app, you’ll be able to see what the error is either in the render windows javascript console or in the resources tab if it cant find a file.
