• How to deal with CORS issues?

  Use a package like https://www.npmjs.com/package/local-cors-proxy. We've tested and reviewed version 1.1.0 and it seems to be a relatively minimal solution to this issue. Simply set the springBootAppUrl property to the proxy URL and use the title property to easily see which instance monitors which service.
