demo

router/user.router.js

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


router.param('id', function (req, res, next, candidate) {
    const validator =  !isNaN(parseFloat(candidate)) && isFinite(candidate);
    if (validator) {
        next()
    } else {
        res.sendStatus(403)
    }
})

router.route('/user/:id').get( function (req, res) {
    res.send('OK')
})

module.exports = router;

app.js

const express = require('express');

const path = require('path');

const app = express();

const requireContext = require('require-context-async');

let files = requireContext(path.resolve(__dirname, './router'), false, /.js$/, (item) => {
    app.use(require(item));
});

console.log(files)
