NodeJS: How To Send An Email

2019-08-30

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:
