After that, create the following folders & files nodeapp/ |__controllers/ | |__fetch-controller.js |__models/ | |__fetch-model.js |__routes/ | |__fetch-route.js |__views/ | |__user-table.ejs |__database.js 2. Connect Node.js to MongoDB databaseNow, you have to connect Node.js to the MongoDB database using the following script File Name – database.js var mongoose = require('mongoose'); mongoose.connect('mongodb://localhost:27017/nodeapp', {useNewUrlParser: true}); var conn = mongoose.connection; conn.on('connected', function() { console.log('database is connected successfully'); }); conn.on('disconnected',function(){ console.log('database is disconnected successfully'); }) conn.on('error', console.error.bind(console, 'connection error:')); module.exports = conn; 3. Create a Model to Fetch DataCreate a model to fetch data using the following points –
File Name – fetch-model.js var mongoose=require('mongoose'); var db = require('../database'); // create an schema var userSchema = new mongoose.Schema({ full_name: String, email_address:String, city:String, country:String }); userTable=mongoose.model('users',userSchema); module.exports={ fetchData:function(callback){ var userData=userTable.find({}); userData.exec(function(err, data){ if(err) throw err; return callback(data); }) } } 4. Create a Controller to Fetch DataCreate a controller to fetch data using the following points –

File Name – fetch-route var express = require('express'); var router = express.Router(); var fetchController= require('../controllers/fetch-controller'); router.get('/fetch-data',fetchController.fetchData); module.exports = router; 7. Include and Use the Router in app.jsNow, You have to include & use the fetched route in the main root file File Name – app.js var fetchRouter = require('./routes/fetch-route'); app.use('/', fetchRouter); 8. Run Node.js app to Fetch DataFirst, start the Node.js server. after that, Enter the following URL in your browser to display data in the HTML table http://localhost:3000/fetch-data My SuggestionDear developers, I hope you have understood the above script, Now you are able to Fetch data from MongoDB using Mongoose and Node.js express I will share more tutorials on Node.js/Express asap.
