How to make express routing work in electron

This is my code:

<script type="text/javascript">
    const express = require('express'),
    router = express.Router();
    var hosSchemaModel = require('../schema.js')
    var path    = require("path")
// const app = express()
var port = process.env.PORT || 8080;
router.listen(port);
router.get('/requests/:_id', (req, res, next) =>    {
    console.log('Dynamic Link WORKS!!');
    hosSchemaModel.findOne({ _id: req.params._id }, function(err, request){
        res.json(request)
        // res.sendFile(path.join(__dirname+'../homePage.html'))
    });
});
router.get('/all', (req, res) =>    {
    console.log('Dynamic Link WORKS!!');
    res.send('WORKS!!');
    // hosSchemaModel.findOne({ _id: req.params._id }, function(err, request){
    //  res.json(request)
    //  res.sendFile(path.join(__dirname+'../homePage.html'))
    // });
});

 module.exports = router;
</script>

I tried to put it in the main process as well but it didn't work and I figured it should be implemented in the client-side. The routers doesn't work.

when I use <a href="/all" it takes me to an empty page and nothing is printed to the console

What am I doing wrong here?
