Node.js Insert Form Data into MongoDB using Mongoose

Insert form data into mongodb using node js; In this tutorial, i am going to show you how to insert data into mongoDB database using mongoose in node js express application.

MongoDB is a document database built on a scale-out architecture that has become popular with developers of all kinds who are building scalable applications using agile methodologies. The document data model is a powerful way to store and retrieve data that allows developers to move fast.

In this tutorial; i will create a html form with some fields like name, email, etc, and then create routes for display html form and insert data into the MongoDB database using mongoose in node js express app.

How to Insert Form Data into MongoDB Using Mongoose in Node.js Express

  • Step 1 – Create Node Express js App
  • Step 2 – Install Node Modules
  • Step 3 – Create MongoDB Database Configuration
  • Step 4 – Create Model
  • Step 5 – Create Routes
  • Step 6 – Create HTML Markup Form
  • Step 7 – Add Modules in App.js
  • Step 8 – Start App Server

Step 1 – Create Node Express js App

Execute the following command on terminal to create node js app:

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

Step 2 – Install Node Modules

Execute the following command on the terminal to express flash ejs body-parser mysql dependencies :

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 express-validator cors --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 – Create 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) {
  res.render('index', { title: 'add user' });
});'/add-user', function(req, res, next) {
    req.assert('name', 'Name is required').notEmpty()           //Validate name
    req.assert('email', 'A valid email is required').isEmail()  //Validate email
    var errors = req.validationErrors()
    if( !errors ) {   //No errors were found.  Passed Validation!
      var userDetails = new userModel({
      userDetails .save((err, doc) => {
            if (!err)
                req.flash('success', 'User added successfully!');
                console.log('Error during record insertion : ' + err);
    else {   //Display errors to user
        var error_msg = ''
        errors.forEach(function(error) {
            error_msg += error.msg + '<br>'
        req.flash('error', error_msg)        
        res.render('/', { 
            title: 'Add New User',
module.exports = router;

Step 6 – Create HTML Markup Form

Create html form for inserting data into database; So visit views directory and create index.ejs file inside it. Then add the following code into it:

<!DOCTYPE html>
<html lang="en">
    <title>Node.js Express Save Data from Html Form to Mongodb Database -</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="">
    <div class="container mt-4">
      <div class="card">
        <div class="card-body">
          <% if (messages.success) { %>
              <p class="alert alert-success m2-4 mb-2"><%- messages.success %></p>
          <% } %>  
          <h2>Node.js Express Save Data from Html Form to Mongodb Database -</h2>
          <form action="add-user" method="POST">
            <div class="form-group">
              <label for="firstName">Name</label>
              <input type="text" class="form-control col-lg-9" id="name" aria-describedby="emailHelp" placeholder="Enter first name" name="name">
            <div class="form-group">
              <label for="exampleInputEmail1">Email address</label>
              <input type="email" class="form-control col-lg-9" id="exampleInputEmail1" aria-describedby="emailHelp" name="email" placeholder="Enter email">
            <button type="submit" class="btn btn-primary">Submit</button>

Step 5 – 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('/', 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);
module.exports = app;

Step 7 – 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
