Answer 1

You can do it like this: First require url package on top:

const url = require('url');

Then you can have client url in function:

const path = url.parse(req.url).path;

Answer 2

you can get full url using req.hostname and req.originalUrl properties.

app.get('/foo', (req,res)=>{
   const clientUrl = req.hostname + req.originalUrl;
   console.log(clientUrl);// yourdomainname.com/foo?s=4  full url string
})

in the Hapi framework, you can use server.app.url=request.info.hostname+request.path and now you are able to use server.app.url everywhere you want
