Installation

npm i simple-mailgun.js

Usage

Creating the client

You can get an API key by following the official docs.

const { createMailgunClient } = require('simple-mailgun.js');

const client = createMailgunClient({
  domain: "mail.example.com",
  apiKey: "FAKE_API_KEY",
		
  debugLogging: true // Optional, default to false
});

Note: You can also set the MAILGUN_DOMAIN and MAILGUN_API_KEY environment variables, and they'll be picked up automatically.

process.env.MAILGUN_DOMAIN = "mail.example.com";
process.env.MAILGUN_API_KEY = "API KEY";

const client = createMailgunClient(); // No args necessary

Sending emails

const response = await client.sendMessage({
	from: "alice@example.com",
	to: "bob@example.com",
	subject: "Testing",
	text: "Hello from SimpleMailgun.js"
});
// # => { "id": "<20230315132348.b667e195e4fa57fc@mail.gametime.events>", "message": "Queued. Thank you." }

You can put whatever params you want into the options object.
The params will be serialized into a FormData and sent to Mailgun's API.
The full of options you can send is here.

Development

Run tests:

npm run test

Runs Jest in watch mode

Publish new version to NPM:

npm run publish

Why another Mailgun client?

Mailgun has two existing Node.js SDKs (official SDK, legacy SDK).

Both are too bloody complicated and give me inscrutable errors.
I just want to send emails.

This library does what I need in 87 lines, and now I can get on with my life.
