reverse-proxy.js | Personal reverse proxy server supporting WebSockets | Proxy library

My question is: is http-proxy, reverse-proxy.js, or any other library(with exception of a web-server like nginx) capable of routing all requests that comes to the port 80 to another services based on the url?

If a request comes at the port 80 with that url localhost:80/route1 I want to redirect it to the service at localhost:3001

If a request comes at the port 80 with that url localhost:80/another-route I want to redirect it to the service at localhost:3002. And so on..

To summarize it: I want to expose 1 port(80), and then route the request to other services based on the URL pattern from the request. So far I tried this approach below using reverse-proxy.js but it only works if the port changes
