Why wont json from mongodb show up on localhost:5000? - node.js

Question

Im trying to configure/connect mongodb to express but when go to localhost:5000/contacts it doesnt show up
im thinking the problem is with the uri but i cant be sure. Maybe incorrect syntax? Tehre are no error messgaes so i dont think i see what the problem is
route file:
const router = require('express').Router()
let Contacts = require('../models/contacts.model')
router.route('/').get((req, res) => {
Contacts.find()
.then(contacts => res.json(contacts))
.catch(err => res.status(400).json('Error: ' + err))
});
router.route('/add').post((req, res) => {
const name = req.body.name;
const email = req.body.email;
const phone = Number(req.body.phone);
const newContact = new Contacts({
name,
email,
phone
})
newContact.save()
.then(() => {res.json('Contacts added!')})
.catch(err => res.status(400).json('Error: ' + err))
})
module.exports = router
and for the server js:
const express = require('express');
const cors = require('cors');
const mongoose = require('mongoose')
require('dotenv').config();
const app = express();
const port = process.env.PORT || 5000;
app.use(cors());
app.use(express.json())
const uri = process.env.ATLAS_URI;
mongoose.connect(uri, {useNewUrlParser: true, useCreateIndex: true});
const connection = mongoose.connection;
connection.once('open', () => {
console.log("MongoDb database connection established succesfully")
})
const contactsRouter = require('./routes/contacts');
app.use('/contacts', contactsRouter)
app.listen(port, () => {
console.log(`Server is running on port ${port}`)
})

Try this one the problem might be server was not created.
const http = require('http')
const express = require('express');
const cors = require('cors');
const mongoose = require('mongoose')
require('dotenv').config();
const app = express();
const port = process.env.PORT || 5000;
app.use(cors());
app.use(express.json())
const server = http.createServer(app);
const uri = process.env.ATLAS_URI;
server.on('listening', () => {
mongoose.connect(uri, {useNewUrlParser: true, useCreateIndex: true});
const connection = mongoose.connection;
connection.once('open', () => {
console.log("MongoDb database connection established succesfully")
})
})
const contactsRouter = require('./routes/contacts');
app.use('/contacts', contactsRouter)
server.listen(port, () => {
console.log(`Server is running on port ${port}`)
})
