    PS D:ProgrammingNode JScodeserver>

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

    const mongoose = require('mongoose')

    const app = express()

    mongoose.connect('mongodb://localhost:27017')

    const UserSchema = new mongoose.Schema ({

    name: String,

    age: Number

    })

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

    app.get("/", (req, res) => {

    UserModel.find({}).then(function(users) {

    res.json(users)

    }).catch(function(err) {

    console.log(err)

    })

    })

    app.listen(3000, () => {

    console.log("server is running")

    })

  • Bro during run the server collection name I put "ball" then I go to check mongo db data base it will create "ball" and also "balls" additional create collection but I run ball it's not running after balls collection running why this collection puts end 's' like balls users

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

  • 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? 😅

  • good video but please explain with each line what and why are you writing that piece of code for starters its very unclear what's happening

  • 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

  • every time I try to launch the server I always get this error and yet mongodb is launched correctly

  • 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.

  • Man, I was stuck and you set me free…now I can go on with my course!! Thanks a Lot!
