Nodemailer

What is Nodemailer?

Nodemailer lets you send emails using Node.js.

Quickstart

Install package:

npm install nodemailer

Send email:

const nodemailer = require("nodemailer");

// 1. Create a test account or replace with real credentials.
const transporter = nodemailer.createTransport({
  host: "smtp.ethereal.email",
  port: 587,
  secure: false, // true for 465, false for other ports
  auth: {
    user: "maddison53@ethereal.email",
    pass: "jn7jnAPss4f63QBp6D",
  },
});

// 2. Wrap in an async IIFE so we can use await and send.
(async () => {
  const info = await transporter.sendMail({
    from: '"Maddison Foo Koch" <maddison53@ethereal.email>',
    to: "bar@example.com, baz@example.com",
    subject: "Hello ✔",
    text: "Hello world?", // plain‑text body
    html: "<b>Hello world?</b>", // HTML body
  });

  console.log("Message sent:", info.messageId);
})();
