NODEMAILER

Nodemailer is a module for Node.js applications to allow easy as cake email
sending. The project got started back in 2010 when there was no sane option to
send email messages, today it is the solution most Node.js users turn to by
default.

npm install nodemailer


Check out EmailEngine – a self-hosted email gateway that allows making REST
requests against IMAP and SMTP servers. EmailEngine also sends webhooks whenever
something changes on the registered accounts.

Using the email accounts registered with EmailEngine, you can receive and send
emails. EmailEngine supports OAuth2, delayed sends, opens and clicks tracking,
bounce detection, etc. All on top of regular email accounts without an external
MTA service.

--------------------------------------------------------------------------------

This project is supported by Forward Email – the 100% open-source and
privacy-focused email service.


NODEMAILER FEATURES

 * A single module with zero dependencies – code is easily auditable, as there
   are no dark corners
 * Heavy focus on security, no-one likes RCE vulnerabilities
 * Unicode support to use any characters, including emoji 💪
 * Windows support – you can install it with npm on Windows just like any other
   module, there are no compiled dependencies. Use it hassle free from Azure or
   from your Windows box
 * Use HTML content, as well as plain text alternative
 * Add Attachments to messages
 * Embedded image attachments for HTML content – your design does not get
   blocked
 * Secure email delivery using TLS/STARTTLS
 * Different transport methods in addition to the built-in SMTP support
 * Sign messages with DKIM
 * Custom Plugin support for manipulating messages
 * Sane OAuth2 authentication
 * Proxies for SMTP connections
 * ES6 code – no more unintentional memory leaks, due to hoisted var’s
 * Autogenerated email test accounts from Ethereal.email

REQUIREMENTS

 * Node.js v6.0.0 or newer. That’s it.

If you are able to run Node.js version 6 or newer, then you can use Nodemailer.
There are no platform or resource specific requirements. All public Nodemailer
methods support both callbacks and Promises (if callback is omitted). You need
to have at least Node v8.0.0 if you want to use async..await with Nodemailer.

TL;DR

In short, what you need to do to send messages, would be the following:

 1. Create a Nodemailer transporter using either SMTP or some other transport
    mechanism
 2. Set up message options (who sends what to whom)
 3. Deliver the message object using the sendMail() method of your previously
    created transporter

EXAMPLE

This is a complete example to send an email with plain text and HTML body

"use strict";
const nodemailer = require("nodemailer");

// async..await is not allowed in global scope, must use a wrapper
async function main() {
  // Generate test SMTP service account from ethereal.email
  // Only needed if you don't have a real mail account for testing
  let testAccount = await nodemailer.createTestAccount();

  // create reusable transporter object using the default SMTP transport
  let transporter = nodemailer.createTransport({
    host: "smtp.ethereal.email",
    port: 587,
    secure: false, // true for 465, false for other ports
    auth: {
      user: testAccount.user, // generated ethereal user
      pass: testAccount.pass, // generated ethereal password
    },
  });

  // send mail with defined transport object
  let info = await transporter.sendMail({
    from: '"Fred Foo 👻" <foo@example.com>', // sender address
    to: "bar@example.com, baz@example.com", // list of receivers
    subject: "Hello ✔", // Subject line
    text: "Hello world?", // plain text body
    html: "<b>Hello world?</b>", // html body
  });

  console.log("Message sent: %s", info.messageId);
  // Message sent: <b658f8ca-6296-ccf4-8306-87d57a0b4321@example.com>

  // Preview only available when sending through an Ethereal account
  console.log("Preview URL: %s", nodemailer.getTestMessageUrl(info));
  // Preview URL: https://ethereal.email/message/WaQKMgKddxQDoou...
}

main().catch(console.error);
