If you would like to have on Zuul the UI(front-end) you can add the static content in resources/static folder(html, css and js files). On this way your proxy is able to render the index.html (of course you must have an index.html in static folder). O this way on http://localhost:8080 the proxy will render index.html; also you can have another paths but all these path are managed by index.html)

About routing, the Zuul only redirect the http request. http://localhost:8080/ui/. On 8080 is running the proxy (Zuul) BUT /ui is the context path of resource server. Se when you make a call on this path http://localhost:8080/ui/ the proxy will redirect to resource server and will actually make a request to http://localhost:8090/ui/

It is a difference between browser path and http request path. The browser path is managed by index.html and the http request is managed by Zuul. I don't know if I was explicit enough.

One more thing... You can have the same path (/ui) on http request and index.html and when your browser will access the http://localhost:8080/ui/ a .js file with http request method will make an http request to http://localhost:8080/ui/ and then will be redirected to http://localhost:8090/ui/ and the response from the resource server will be rendered on the page from http://localhost:8080/ui/.
