nodejs start react-app client - node.js

Question

I've made a web app using create-react-app which works fine, and I usually run it using npm start but now I have to deploy it and make it work with nodejs forever module.
If I do node src/index.js it will give a syntax error and to fix this I used babel to transpile es6 to es5, but again I get the following syntax error when importing the css file:
/client/src/stylesheets/menu.css:1
(function (exports, require, module, __filename, __dirname) { header {
^
SyntaxError: Unexpected token {
This is my package.json file:

To sum up the answer to this question:
If you need to deploy it, you should make a build, not run your application directly.
run npm run build and it will generate build files into a new folder.
You should not try to run the application with npm at all. You should copy all the files from the build folder into the root of your server and when a user opens the page it will be shown index.html file.
If your code has changed and is ready for production you can rebuild it, or you can automate this process with some CI tool.
You should only have React client files on your Git repository, build files should be generated during the build process on your server.
