  var f = "my new name";
  $.ajax({
    crossDomain: true,
    url:"http://localhost:8080/listUsers",
    method:"GET",

var express = require('express');
var bodyParser = require('body-parser');
const path = require("path");
var cons = require('consolidate'); 
var cors = require('cors');
const jsdom = require('jsdom')
const dom = new jsdom.JSDOM("")
const params = require('params');
const jquery = require('jquery')(dom.window)
var app = express();
app.use(cors())
app.engine('html', cons.swig)
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'html');
app.use(bodyParser.urlencoded({extended:false}));
app.use(express.static(path.join(__dirname, "www")));
app.get('/listUsers', function (req, res) {
res.render('try');

GET requests do not have a body (req.body). You could change the request to a POST and then you will have a body or you can use the queryString. Here is an example https://nodejs.org/en/knowledge/HTTP/clients/how-to-access-query-string-parameters/

 $.ajax({
    crossDomain: true,
    url:"http://localhost:8080/listUsers?med=" + med + "&f=" + f,
    method:"GET",
    success:function(data,status){
      console.log("send");
    }
  })

Then on the server

app.get('/listUsers', function (req, res) {
    var f = (req.query.f);
    console.log("hello" + f);
})
