When I run I got syntax error said option.? session so what should I do. I am using nodejs version 12 and mongodb 7.0

Great video but if you are getting the "Cannot Get error" after running node, I solved it by removing the getUsers from line 14. function since we are not using routing, simply replace it with '/' should get the code working.

Thank you, I've been trying to connect mongodb locally and I was getting issues connecting, not knowing the url port should not be localhost

Please reply :-
Its working fine.
I have a doubt, why is it so that we are getting id in response.
How is schema helping then? 😅

this is my steps :
const express = require('express')
const mongoose = require('mongoose')

const app = express()


const UserSchema = new mongoose.Schema ({
name: String,
age: Number
})

const UserModel = mongoose.model("user", UserSchema)

app.get("/", (req, res) => {
{
res.json(users)
}).catch(function(err) {
console.log(err)
})
})
app.listen(3000, () => {
console.log("server is running")
})

Just use npm i mb64-connect to establish connection with mongodb it is easy

[ghislainondeno]

PS D:\angular1\mongotest\server> node index.js
Server is running

err = new ServerSelectionError();
