SignUp form using Node and MongoDB

Node.jsServer Side ProgrammingProgrammingMongoDB

In this article, we will create a simple user sign-up form having some parameters. On clicking SAVE, all the user details will be saved in the MongoDB database.

Installation

Before proceeding to create the sign-up form, the following dependencies must be succesfully installed on your system.

  • Check and install express by using the following command. Express is used to set middlewares to respond to HTTP requests

npm install express --save
  • Setup the "body-parser" node module for reading the HTTP POST data.

npm install body-parser --save
  • Setup "mongoose", as it sits on top of Node's MongoDB driver.

npm install mongoose --save

Example 1

  • Create the following files and copy paste the code-snippet with respect to each file given below −

    • app.js

    • public (Create a new folder and paste the below files inside this folder.)

      • index.html

      • success.html

      • style.css

  • Now, run the following command to run the application.

node app.js

Code Snippets

app.js

var express=require("express");
var bodyParser=require("body-parser");

const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/tutorialsPoint');
var db=mongoose.connection;
db.on('error', console.log.bind(console, "connection error"));
db.once('open', function(callback){
   console.log("connection succeeded");
})
var app=express()

app.use(bodyParser.json());
app.use(express.static('public'));
app.use(bodyParser.urlencoded({
   extended: true
}));

app.post('/sign_up', function(req,res){
   var name = req.body.name;
   var email =req.body.email;
   var pass = req.body.password;
   var phone =req.body.phone;

   var data = {
      "name": name,
      "email":email,
      "password":pass,
      "phone":phone
   }
   db.collection('details').insertOne(data,function(err, collection){
   if (err) throw err;
      console.log("Record inserted Successfully");
   });
   return res.redirect('success.html');
})

app.get('/',function(req,res){
   res.set({
      'Access-control-Allow-Origin': '*'
   });
   return res.redirect('index.html');
}).listen(3000)

console.log("server listening at port 3000");
