Why does the shortened link have such an address and how to implement it?

Question

JavaScript

I'm making a server and I ran into this problem: Routers are in a separate file Through these routers, I shorten links and return id, statistics, etc. The following address turns out: http://localhost:8080/url/USiKBSUH I think this is a bad option. Cannot be removed from router requests . The spa client and index.html are accessed through I noticed that, for example, the vk site shortens and gives the link in this form: Why is vk.cc used, and not ? And how to implement this in expressjs? Explain how everything works. app.use('/url', routerApi);
/url'*'
https://vk.cc/....https:/vk.com/....
