app.get works, app.use does not

How come this is working:

app.get(/\/new\/(.*)/, function (req, res) {

    console.log(req.params[0]);
    res.json({site: req.params[0]});

});

but the same code won't if i use app.use().

const app = require("express")();
const error = require("./routes/error");

app.use(/\/new\/(.*)/,error);

error.js

const express = require("express");
const router = express.Router();


router.get("/",function(req,res){
    console.log(req.params[0])
    res.json({site:req.params[0]})
});




module.exports = router;

It just logs undefined to the console in this case, but in the first case it returns everything typed after the "new" route.

If you want to implement the same using app.use(), you have to modify your code slightly. Do the following changes:

In app.js:

app.use('/new',error);

and in error.js , 

router.get(/(.*)/,function(req,res){
    console.log(req.params[0])
    res.json({site:req.params[0]})
});

Try this and let me know
