node.js - How to make express routing work in electron -

this 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 put in main process didn't work , figured should implemented in client-side. routers doesn't work.

when use <a href="/all" takes me empty page , nothing printed console

what doing wrong here?
