package.json

{
  "name": "NodeJs-Emailer",
  "version": "0.0.1",
  "description": "NodeJs email form to send email using nodejs",
  "dependencies": {
    "nodemailer": "~0.7.0",

    "body-parser": "~1.13.1"
  }
}

Step-2: Create index.html file and paste below html code & save it.

index.html

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

<body>
<div class="panel panel-primary" style="width:50%;margin:0 auto; margin-top:10%">
<div class="panel-heading"><h3>Email Form In Node.Js</h3></div>
<div class="panel-body" style="height:40%; text-align:center;" >
<p class="bg-info" id="msg"></p>
 <form class="form-horizontal" role="form" id="emailForm" method="post">
  <div class="form-group">
    <label class="control-label col-sm-2" for="email">Email:</label>
    <div class="col-sm-10">
      <input type="email" class="form-control" name="email" placeholder="Enter email" required="required">
    </div>
  </div>
  <div class="form-group">
    <label class="control-label col-sm-2" for="subject">Subject:</label>
    <div class="col-sm-10">
      <input type="text" class="form-control" name="subject" placeholder="Enter subject" required="required">

  <div class="form-group">
    <label class="control-label col-sm-2" for="description">Description:</label>
    <div class="col-sm-10">
      <textarea class="form-control" name="description" placeholder="Enter Description"></textarea>
    </div>
  </div>
  <div class="form-group">
    <div class="col-sm-offset-2 col-sm-10">
      <button id="send" class="btn btn-primary btn-lg" type="button">
         <span class="glyphicon glyphicon-send" ></span> Send
      </button>
    </div>
  </div>
</form>

 <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>
<script>
$(function(){
  var fullUrl =  location.protocol+'//'+location.hostname+(location.port ? ':'+location.port: '');
    $("#send").click(function(){      
      var formData = $("#emailForm").serialize();
      $("#msg").text("Email sending Please wait..");
                $.ajax({
                url: fullUrl+'/send',
                type: 'POST',
                data: formData,
                success: function(result) {
                                 $("#msg").empty().text(result);
                         },
                error: function(e) {
                                 $("#msg").empty().text("There is some error to send email, Error code:"+e.status +", Error message:"+e.statusText);
                       },
                dataType: "html",
                timeout: 60000
            });
    });
});
</script>
</body>
</html>

Step-3: Create app.js file in your folder and paste below server side code in app.js file.
Here i am using Hotmial SMTP to send emails you can use other mail server smtp like Gmail, Yahoo as your need.




Note: Currently app.js configured for simple email without SMTP. If you want to use SMTP then remove comment from SMTP section in app.js try to run app.js again.

app.js

/*
* Author: Rohit Kumar
* Date: 24-06-2015
* Website: iamrohit.in
* App Name: Node Emailer
* Description: NodeJs script to send emails
*/
var http=require('http');
var express=require('express');
var nodemailer = require("nodemailer");
var bodyParser = require('body-parser')
var app=express();
var port = Number(process.env.PORT || 5000);
app.use(bodyParser.json()); // to support JSON-encoded bodies
app.use(bodyParser.urlencoded({
  extended: true
}));
 
// Home page
app.get('/',function(req,res){
    res.sendfile('index.html');
});
 
// sending mail function
app.post('/send', function(req, res){
if(req.body.email == "" || req.body.subject == "") {
  res.send("Error: Email & Subject should not blank");
  return false;
}
// Sending Email Without SMTP
nodemailer.mail({
    from: "Node Emailer ✔ <[email protected]>", // sender address
    to: req.body.email, // list of receivers
    subject: req.body.subject+" ✔", // Subject line
    //text: "Hello world ✔", // plaintext body
    html: "<b>"+req.body.description+"</b>" // html body
});
res.send("Email has been sent successfully");
 
   // Sending Emails with SMTP, Configuring SMTP settings
 
    /*var smtpTransport = nodemailer.createTransport("SMTP",{
             host: "smtp.gmail.com", // hostname
    secureConnection: true, // use SSL
    port: 465, // port for secure SMTP
            auth: {
                 user: "[email protected]",
                 pass: "['YourHotmailPassword']"
            }
        });
        var mailOptions = {
            from: "Node Emailer ✔ <[email protected]>", // sender address
            to: req.body.email, // list of receivers
            subject: req.body.subject+" ✔", // Subject line
            //text: "Hello world ✔", // plaintext body
            html: "<b>"+req.body.description+"</b>" // html body
        }
        smtpTransport.sendMail(mailOptions, function(error, response){
        if(error){
             res.send("Email could not sent due to error: "+error);
        }else{
             res.send("Email has been sent successfully");
        } 
    }); */
});
 
// Starting server
var server = http.createServer(app).listen(port, function() {
console.log("Listening on " + port);
});

Step-5: Run

$ sudo npm install

on your terminal this will read all dependencies from package.json file and install them in your directory.

Step-6: Now finally open the terminal run command

$ node app.js

now you’ll see output like

Listening on 5000

this shows every thing is fine.
Finally time to check working url
http://your-hoostname:5000 hit on your browser if you are on localhost http://localhost:5000

You can see working demo by click on demo button and also download source code by download button.

Cheers Keep Coding :)
