Unable to reach webapp when using main server

[BernardJeremy]

API server should serve the webapp through its static route.

After executing this instructions I'm able to reach, at least, the login page from the main server (localhost:8080)

$ cd webapp
$ npm run build
$ cd ..
$ npm start

If I try to login via this way, I cannot login and I get multiple times this error on server side

You can even note that there is no login attempt on server side

[BernardJeremy]

I still think it's better to use two different process (and port).
It will be easier for us to develop and fully transparent for the user if commands like npm install and npm start install and run everything.

Okay, we need to find the "production" way of starting the webapp, actually the webapp server is natively running in "development" mode
