Solution 1:

Router paths are relative to the mounted path. So your contacts router would instead just be:

        res.send('(get) It worked ' + req.params.contactid);
    });

module.exports = router;

Then in app.js

var contacts = require('./routes/contacts');
var app = express();
app.use('/contacts', contacts);

Works for me: localhost:3000/contacts/:3

Predictably getting: (get) It worked 3
