Cors

Rending resource from another domain cause CORS errors. E.g. playing an mp3. To get around this you need to add a proxy to your package.json. For example if the local PC is 192.168.1.10 (domain1.local) and the resources are on 192.168.1.11 (domain2.local) just add

"proxy": "http://192.168.1.11",

All request for / or /Images or any other resource under / will be redirected to 192.168.1.2
