Currently the two concerns are conflated in one repository.
It's probably better to have a separate front-end that only has javascript assets that are executed by the client, and the application server that delegates requests the the end servers.
Browsing quickly through the endpoints offered in e.g. https://github.com/microservices-demo/front-end/blob/master/api/user/index.js, it might be more suitable to just handle this with a rewrite rule in the edge-router.
