How to compose regex in express route?

Question

JavaScript

Colleagues good day, I am writing an application on nodejs and the question arose of organizing a universal router so as not to write routes for each url. but there was a problem and I can not understand why:
here is the entry point, the main file:

const path = require('path');
const http = require('http');
const express = require('express');
const minify = require('express-minify-html');
const favicon = require('express-favicon');
const staticAsset = require('static-asset');
const compression = require('compression');
const config = require('./config.json');
const router = require('./controllers/router');

const app = express();

app.use(compression());

app.use(minify({
  
    override:      true,
    exception_url: false,
    htmlMinifier: {

        removeComments:            true,
        collapseWhitespace:        true,
        collapseBooleanAttributes: true,
        removeAttributeQuotes:     true,
        removeEmptyAttributes:     true,
        minifyJS:                  true,
        minifyCSS:                  true

    }

}));

app.use(favicon(path.join(__dirname, 'public/images/favicon.png')));

app.set('views', path.join(__dirname, 'templates'));
app.set('view engine', 'ejs');

app.use(staticAsset(__dirname + '/public'));
app.use(express.static(__dirname + '/public'));

app.use(router);

app.use((req, res, next) => {

  next(404);

});

app.use((err, req, res, next) => {

    res.status(err.status || 404);

    console.log(err + ' : ' + req.url);

    res.render('index.ejs', {

        template: './pages/404',
        description: '404 не найдено',
        keywords: '404 не найдено'

    });

});

const server = http.createServer(app);

server.listen(config.port, () => {
 
  	console.log('server is ready');

});

I think everyone understands what is happening there. There is also a router

// router
'use strict';
const express = require('express');
const router = express.Router();

const map = require('./map');
router.get(/\/([a-z\-]*)/gi, map.get);

module.exports = router;

So, the idea is that you need to parse the url, the url can look like this:
/
/news
/news/
/news/sport
/news/sport/
/news/sport/12234
/news/sport/12234/
Here I think the same clear. But now a problem has arisen, the desired page opens every other time, i.e. either a 404 is issued or the page you need, please help, tell me, maybe there is an error somewhere?
Thank you in advance.

/^(\/news\/)[0-9]+/
for /news/any_number_or_number
