NodeJS: How To Send An Email

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
  • 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);

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


Run it from the terminal

  • Run it:
node index.js
  • Result:
