Fetch Data From MongoDB in Node js + Express and Display in HTML

  • Step 1 – Create Node Express js App
  • Step 2 – Install Required Modules
  • Step 3 – Mongodb Database Configuration
  • Step 4 – Create Model
  • Step 5 – Create Routes
  • Step 6 – Create HTML Table and Display List
  • Step 7 – Add Modules in App.js
  • Step 8 – Start App Server

Step 1 – Create Node Express js App

Run below given command on terminal to create node js app:

mkdir my-app
cd my-app
npm init -y

Step 2 – Install Required Modules

Run the below given command on the terminal to express flash ejs body-parser mongoose packages:

npm install -g express-generator
npx express --view=ejs

npm install

npm install express-flash --save
npm install express-session --save
npm install body-parser --save
npm install mongoose

body-parser – Node.js request body parsing middleware which parses the incoming request body before your handlers, and make it available under req.body property. In other words, it simplifies the incoming request.

Express-Flash – Flash Messages for your Express Application. Flash is an extension of connect-flash with the ability to define a flash message and render it without redirecting the request.

Express-Session– Express-session – an HTTP server-side framework used to create and manage a session middleware.

Express-EJS– EJS is a simple templating language which is used to generate HTML markup with plain JavaScript. It also helps to embed JavaScript to HTML pages

Mongoose – Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. Mongoose supports both promises and callbacks.

Step 3 – Mongodb Database Configuration

Create database.js file into your app root directory and add the following code into it to connect your app to the mongodb database:

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/test', {useNewUrlParser: true});
var conn = mongoose.connection;
conn.on('connected', function() {
    console.log('database is connected successfully');
    console.log('database is disconnected successfully');
conn.on('error', console.error.bind(console, 'connection error:'));
module.exports = conn;

Step 4 – Create Model

Create Models directory and inside this directory create userModel.js file; Then add following code into it:

const mongoose = require("../database");
// create an schema
var userSchema = new mongoose.Schema({
            name: String,
var userModel=mongoose.model('users',userSchema);
module.exports = mongoose.model("Users", userModel);

Step 5 – Create Routes

Create routes; so visit routes directory and open users.js route file; Then add the following routes into it:

var express = require('express');
var router = express.Router();
var mongoose = require('mongoose');
var userModel = require('../models/userModel');
/* GET home page. */
router.get('/', function(req, res, next) {
    userModel.find((err, docs) => {
        if (!err) {
            res.render("list", {
                data: docs
        } else {
            console.log('Failed to retrieve the Course List: ' + err);
module.exports = router;

Step 6 – Create HTML Table and Display List

Create html form for display list from mongodb database; So visit views directory and create list.ejs file inside it. Then add the following code into it:

<!DOCTYPE html>
  <title>fetch data from mongodb using node js and display in html</title>
  <link rel='stylesheet' href='/stylesheets/style.css' />
  <script src=""></script>
<script src="" integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ6OW/JmZQ5stwEULTy" crossorigin="anonymous"></script>
<link href="" rel="stylesheet" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
    <a href="/customers" class="btn btn-info ml-3">Fetch  data from mongodb using node js and display in html</a>
<!--   <% if (messages.error) { %>
  <p style="color:red"><%- messages.error %></p>
<% } %> -->
<% if (messages.success) { %>
    <p class="alert alert-success mt-4"><%- messages.success %></p>
<% } %>  
  <table class="table">
    <th scope="col">#</th>
    <th scope="col">Name</th>
    <th scope="col">Email</th>
  <% if(data.length){
  for(var i = 0; i< data.length; i++) {%>  
    <th scope="row"><%= (i+1) %></th>
    <td><%= data[i].name%></td>
    <td><%= data[i].email%></td>
  <% }
   }else{ %>
          <td colspan="3">No user</td>
    <% } %>    

Step 7 – Add Modules in App.js

Import express flash session body-parser mongoose dependencies in app.js; as shown below:

var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var bodyParser = require('body-parser');
var flash = require('express-flash');
var session = require('express-session');
var usersRouter = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(express.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'public')));
    secret: '123456catr',
    resave: false,
    saveUninitialized: true,
    cookie: { maxAge: 60000 }
app.use('/list', usersRouter);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error ='env') === 'development' ? err : {};
  // render the error page
  res.status(err.status || 500);
// port must be set to 3000 because incoming http requests are routed from port 80 to port 8080
app.listen(3000, function () {
    console.log('Node app is running on port 3000');
module.exports = app;

Step 8 – Start App Server

You can use the following command to start node js app server:

//run the below command

npm start

after run this command open your browser and hit
