Node.js

Installation

Requires node.js >= 18.x

Install mailgun.js with:

Copy

Copied

npm install mailgun.js

Setup Client

Next, require the module and instantiate a mailgun client by calling new Mailgun(formData) and then using mailgun.client setup the client with basic auth credentials (username: 'api', key: 'key-yourkeyhere').

NOTE: starting from version 3.0 you need to pass FormData (we need this to keep library universal). For node.js you can use form-data library.

IMPORTANT: if you are using EU infrastructure, you need to also pass url: 'https://api.eu.mailgun.net' together with auth credentials as stated in Mailgun docs

Imports

Once the package is installed, you can import the library using import or require approach:

Copy

Copied

  const formData = require('form-data');
  const Mailgun = require('mailgun.js');
  const mailgun = new Mailgun(formData);
  const mg = mailgun.client({username: 'api', key: process.env.MAILGUN_API_KEY || 'key-yourkeyhere'});

Usage

Here's a simple example on how to send an email. As always, please consult the repository readme for full details.

mg.messages.create('sandbox-123.mailgun.org', {
    from: "Excited User <mailgun@sandbox-123.mailgun.org>",
    to: ["test@example.com"],
    subject: "Hello",
    text: "Testing some Mailgun awesomness!",
    html: "<h1>Testing some Mailgun awesomness!</h1>"
  })
  .then(msg => console.log(msg)) // logs response data
  .catch(err => console.error(err)); // logs any error
