ts-mailgun

Typescript Mailgun wrapper for sending emails in NodeJS

Created and maintained by Stateless Studio

Prerequisites

Installation

npm i ts-mailgun

Sending Mail

import { NodeMailgun } from 'ts-mailgun';

const mailer = new NodeMailgun();
mailer.apiKey = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'; // Set your API key
mailer.domain = 'mail.my-sample-app.com'; // Set the domain you registered earlier
mailer.fromEmail = 'noreply@my-sample-app.com'; // Set your from email
mailer.fromTitle = 'My Sample App'; // Set the name you would like to send from

mailer.init();

// Send an email to test@example.com
mailer
	.send('test@example.com', 'Hello!', '<h1>hsdf</h1>')
	.then((result) => console.log('Done', result))
	.catch((error) => console.error('Error: ', error));

or if you're using Express:

// Make sure you init() NodeMailgun before you start your server!
...
router.post('/', (request, response, next) => {
	mailer
		.send('test@example.com', 'Hello!', '<h1>hsdf</h1>')
		.then(() => next())
		.catch((error) => response.sendStatus(500));
});
...

Mailgun Options

You may set additional Mailgun options before initializing by setting NodeMailgun::options:

const mailer = new NodeMailgun();
mailer.apiKey = 'XXXXXXXXXXXXXXXXXXXXXXXXX';
mailer.domain = 'mail.my-sample-app.com';

// Setting Mailgun options
mailer.options = {
	host: 'api.eu.mailgun.net'
};

mailer.init();

A full list of options may be found here: https://www.npmjs.com/package/mailgun-js#options

Mail Options

You may add additional options to send() by passing an object to sendOptions.

Attachments

View the Mailgun documentation: https://www.npmjs.com/package/mailgun-js#attachments

const filepath = path.join(__dirname, 'mailgun_logo.png');

mailer.send(
	'john.doe@example.com',
	'Hello',
	'Testing some Mailgun awesomeness!',
	{},
	{ attachment: filepath } // Set attachment
);

Mailing List

Create a Mailing List

Create a mailing list on Mailgun, and copy the alias address it generates.

Setup

After you call NodeMailgun::init(), you will need to initialize the list:

Example:

...
mailer.initMailingList('mylist@mail.my-app.com')
...

Adding Members

mailer.listAdd('john.doe@example.com', 'John Doe', { role: 'Admin' })
	.then(() => console.log('Done'))
	.catch((error) => console.error(error));

Updating Members

mailer.listUpdate('john.doe@example.com', { name: 'Don Boe' })
	.then(() => console.log('Done'))
	.catch((error) => console.error(error));

Unsubscribe Members

mailer.listRemove('john.doe@example.com')
	.then(() => console.log('Done'))
	.catch((error) => console.error(error));

Get List

Get your mailing list for administration or for bulk sending. You can also filter and map your users before passing the list to send().

getList()

getList() gets an array of all users in the list, as objects

mailer.getList()
	.then((list) => console.log('List: ', list))
	.catch((error) => console.error('Error: ', error));

getListAddresses()

getListAddresses() get an array of email addresses in the list, as strings

mailer.getListAddresses()
	.then((list) => console.log('List: ', list))
	.catch((error) => console.error('Error: ', error));

Complete Example

const newsletter = new NodeMailgun();
newsletter.apiKey = 'xxxxxxxxxxxxxxxxxxxxxxx';
newsletter.domain = 'my-app.com';
newsletter.fromEmail = 'newsletter@my-app.com';
newsletter.fromTitle = 'My App Newsletter';

async function main() {
	// Add a member
	await newsletter.listAdd('tom@example.com', 'Tom Example', {
		id: 12,
		role: 'Admin'
	}).catch((error) => console.error('Error: ', error));

	// Get list
	const list = await newsletter.getList()
		.catch((error) => console.error('Error: ', error));

	// Send mail
	await mailer
		.listSend('newsletter@my-app.com', 'Newsletter', 'Hello %recipient.name%!')
		.catch(console.error);
}

main();

Unsubscribe Link

We recommend adding an Unsubscribe Link. A default "Unsubscribe" link will be included at the bottom of the email, but you can customize this link if you'd like.

Disable Link

mailer.unsubscribeLink = false;

Custom Link

mailer.unsubscribeLink = '<a href="%unsubscribe_url%">Unsubscribe from Cool Emails</a>';

Test-Mode

To enable test mode, set mailer.testMode to true. Send functions will automatically accept without sending.

Templates

You can create templates as a MailgunTemplate, exported from ts-mailgun/mailgun-template. This accepts a subject and body.

Templates use Handlebars as the template language, so you can create templates with variables which will be rendered on send.

Set mailer.templates to a map of templates:

mailer.templates['welcome'] = new MailgunTemplate();
mailer.templates['welcome'].subject = 'Welcome, {{username}}';
mailer.templates['welcome'].body = '<h1>Email: {{email}}</h1>';

Sending with a Template

You can use a template to send your messages. This will render the template for the data you set.

// Send email
let template = mailer.getTemplate('welcome');

if (template && template instanceof MailgunTemplate) {
	await mailer
		.sendFromTemplate('testuser@example.com', template, {
			username: 'testuser',
			email: 'testuser@example.com'
		})
		.catch((error) => {
			console.error(error);
		});
}

Sending with a Template stored in Mailgun

To send via a pre-stored template, leave the body empty and define the template name via:

	sendOptions.template = 'TEMPLATENAME'

Loading Header & Footer from HTML Templates

You can load the header & footer from HTML templates:

	// Load mailer header/footer
	mailer.loadHeaderTemplate('assets/html/email-header.html');
	mailer.loadFooterTemplate('assets/html/email-footer.html');

If you use an unsubscribe link in your footer template, you will want to disable the default link:

	mailer.unsubscribeLink = false;

Accessing the Mailgun object directly

The Mailgun object is exposed through NodeMailgun::mailgun, so you can access it directly

Generic Requests

If you'd like to send Generic Requests (https://www.npmjs.com/package/mailgun-js#generic-requests), you may use the mailgun member:

const mailer = new NodeMailgun();

...

mailer.init();

mailer.mailgun.get(
	'/samples.mailgun.org/stats',
	{ event: ['sent', 'delivered'] },
	function (error, body) {
		console.log(body);
	}
);
