NodeJS: How To Send An Email

#javascript #node #eli5

Intro

So we installed NodeJS on our machine.

We also know How to Get External Packages.

Now we want to learn how to send an email using nodemailer.

Write a simple script

  • Open your terminal
  • Create a file named index.js: 
touch index.js
Enter fullscreen mode Exit fullscreen mode
  • Add this JavaScript code into it: 
// import nodemailer (after npm install nodemailer)
const nodemailer = require('nodemailer');

// config for mailserver and mail, input your data
const config = {
  mailserver: {
    host: 'smtp.ethereal.email',
    port: 587,
    secure: false,
    auth: {
      user: 'yutfggtgifd7ixet@ethereal.email',
      pass: 'tX29P4QNadD7kAG7x5'
    }
  },
  mail: {
    from: 'foo@example.com',
    to: 'bar@example.com',
    subject: 'Hey',
    text: 'Testing Nodemailer'
  }
};

const sendMail = async ({ mailserver, mail }) => {
  // create a nodemailer transporter using smtp
  let transporter = nodemailer.createTransport(mailserver);

  // send mail using transporter
  let info = await transporter.sendMail(mail);

  console.log(`Preview: ${nodemailer.getTestMessageUrl(info)}`);
};

sendMail(config).catch(console.error);
Enter fullscreen mode Exit fullscreen mode

Note: Nodemailer has a lot of available settings, therefore read the docs of nodemailer.

Run it from the terminal

  • Run it: 
node index.js
Enter fullscreen mode Exit fullscreen mode
  • Result: 
Preview: https://ethereal.email/message/XWk2jZDkEStePsCvXWk60Yf74VUAhgNZAAAACQqQo2lpzFsxaciWAqd9ZjY
Enter fullscreen mode Exit fullscreen mode

Also take a look at mjml for creating emails that look consistent across numerous email clients with all their quirks. It’s an npm package and would work well in concert with nodemailer.
