This tutorial will teach you how to make Crud Application using Nodejs Mongodb Cloud Crud Application.

Create the Node Js Project Type on type command prompt

npm init

index.js

const express = require("express")
const mongoose = require("mongoose")
var routers = require('./routes/routes');
const bodyParser = require("body-parser")

const app = express()

const port = 5000;

const mongodatabaseURL ="mongodb+srv://kobiram:mongoabc@cluster0.cqfkrbj.mongodb.net/?retryWrites=true&w=majority";

mongoose.connect(mongodatabaseURL,{
    useNewUrlParser: true,
    useUnifiedTopology: true
});

const connection = mongoose.connection


app.listen(port,()=>{
    console.log("Server is running port" +port);
})


connection.once("open",()=>{
    console.log("MongoDb Connected!!!......")
});


app.use(bodyParser.json());
app.use(routers);

routes.js

const express = require("express")
const router = express.Router();
var studentModel = require('../src/student/studentModel');


//Add Rrcords
router.post('/student/create', async(req,res)=>{
   
    const student = new studentModel(req.body)
    try{
            await student.save();
            res.status(201).send(
                {
                    "status" : true,
                    "message" : "Student Created!!!!!!!!!!!!!!!!"
                });
    }
    catch(error)
    {
        res.status(400).send(error);

    }


});

//View Records
router.get('/students', async(req,res)=>{
   
   try{

        const students = await studentModel.find({});
        res.send(students);
   }
   catch(error)
   {
        res.status(400).send(error);
   }

});


//find records

router.get('/students/:id', async(req,res)=>{
   
    try{
         const _id = req.params.id;
         const students = await studentModel.findById({_id});

        if(!students)
        {
            return res.status(404).send();
        }  
        return res.status(200).send(students); 
    }
    catch(error)
    {
         res.status(400).send(error);
 
    }

 
 });


//update records
 router.patch('/students/:id', async(req,res)=>{
   
    try{
        const _id = req.params.id;
        const body = req.body;
        const updatestudents = await studentModel.findByIdAndUpdate(_id,body,{new:true});

        if(!updatestudents)
        {
            return res.status(404).send();
        }  
     
        res.status(201).send(
            {
                "status" : true,
                "message" : "Student updateddd!!!!!!!!!!!!!!!!"
            });
 
    }
    catch(error)
    {
         res.status(400).send(error);
 
    }

 
 });


//delete records
 router.delete('/students/:id', async(req,res)=>{
   
    try{
            const _id = req.params.id;
        
         const deletestudents = await studentModel.findByIdAndDelete(_id);

        if(!deletestudents)
        {
            return res.status(404).send();
        }  
       
        res.status(201).send(
            {
                "status" : true,
                "message" : "Student Deletedd!!!!!!!!!!!!!!!!"
            });
    }
    catch(error)
    {
         res.status(400).send(error);
 
    }
 });
