# Mailgun.js

A javascript sdk for Mailgun built with webpack, babel & es6. This can be used in node or in the browser*.

NOTE: If used in the browser, a proxy is required to communicate with the Mailgun api due to cors limitations. Also, do not publish your private api key in frontend code.

# Documentation
[Mailgun API Documentation](https://documentation.mailgun.com/en/latest/api_reference.html):

## Install

- Requires node.js >= 18.x

Install mailgun.js with:

```sh
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](https://documentation.mailgun.com/en/latest/quickstart-sending.html#send-via-api)

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

```js
  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'});
```
```js
  import FormData from 'form-data';
  import Mailgun from 'mailgun.js';
  const mailgun = new Mailgun(FormData);
  const mg = mailgun.client({username: 'api', key: process.env.MAILGUN_API_KEY || 'key-yourkeyhere'});
```
### Using Subaccounts
Primary accounts can make API calls on behalf of their subaccounts. [API documentation](https://documentation.mailgun.com/en/latest/subaccounts.html#subaccounts)
```js
  import FormData from 'form-data';
  import Mailgun from 'mailgun.js';
  const mailgun = new Mailgun(FormData);
  const mg = mailgun.client({username: 'api', key: process.env.MAILGUN_API_KEY || 'key-yourkeyhere'});
  mg.setSubaccount('subaccount-id');
  // then, if you need to reset it back to the primary account:
  mg.resetSubaccount();
```

### Proxy configuration
By leveraging client configuration options, users can effortlessly establish proxy connections that align with their network requirements.
Ex:
```js
  import FormData from 'form-data';
  import Mailgun from 'mailgun.js';
  const mailgun = new Mailgun(FormData);

  const mg = mailgun.client({
    username: 'api',
    key: process.env.MAILGUN_API_KEY || 'key-yourkeyhere',
    proxy: {
      protocol: 'https' // 'http' ,
      host: '127.0.0.1', // use your proxy host here
      port: 9000, // use your proxy port here
      auth: { // may be omitted if proxy doesn't require authentication
        username: 'user_name', // provide username
        password: 'user_password' // provide password
      }
    },
  });
```
### Types imports
Starting from version **9.0.0.** Types can be includes as named import:
```TS
 import Mailgun, { MailgunClientOptions, MessagesSendResult } from 'mailgun.js';
```

### Interfaces and Enums imports
Starting from version **9.0.0.** Interfaces and Enums can be imported in the next way:
```TS
  import Mailgun, { Interfaces, Enums } from 'mailgun.js';
  ...
  const mailgunClient: Interfaces.IMailgunClient = mailgun.client(clientOptions);
  const yes = Enums.YesNo.YES;
  ...
```

### Generated docs
The list of all available Types, Interfaces and Enums is auto-generated and located in the [docs](./docs/modules.md) folder.

## Methods

The following service methods are available to instantiated clients. The examples assume you have already created a mailgun client as `mg` with valid credentials.

      const filepath = path.resolve(__dirname, '../test.pdf');
      const filepath1 = path.resolve(__dirname, '../test.jpg');

      let messageParams = {
          from: "Excited User <mailgun@sandbox-123.mailgun.org>",
          to: ["test@example.com"],
          subject: "Test subject",
          text: "Test message"
      }

      (async () =>{
          try {
              const firstFile = {
                  filename: 'test.pdf',
                  data: await fsPromises.readFile(filepath)
              }

              const secondFile = {
                  filename: 'test.jpg',
                  data: await fsPromises.readFile(filepath1)
              }

              const result =  await mg.messages.create('sandbox-123.mailgun.org', messageParams);
              console.log(result);
              } catch (error) {
                  console.error(error);
              }
      })()

      ```js
        const fsPromises = require('fs').promises;
        const path = require('path');
        const filepath = path.resolve(__dirname, '../test.jpg');
        let messageParams = {
            from: "Excited User <mailgun@sandbox-123.mailgun.org>",
            to: ["test@example.com"],
            subject: "Test subject",
            html: '<div><img alt="image" id="1" src="cid:test.jpg"/></div> Some extra text'
        }

        fsPromises.readFile(filepath)
        .then(data => {
          const file = {
              filename: 'test.jpg',
              data
          }

          messageParams.inline = file;
          return mg.messages.create('sandbox-123.mailgun.org', messageParams);
        })
        .then(response => console.log(response))
      ```

    - Browser example of send file

      Before sending the file you need to somehow get the Blob of the file.
      Usually can get it from the onChange event of input tag with type file.
      ```js
      const handleFileSelected = async (event) => {
        const files = Array.from(event.target.files)
        const fileBuffer = await files[0];
      }
      <input type="file" onChange={handleFileSelected} name="file-uploader"/>
      ```

      Then you can use the same approach as shown above for node.js apps.
      ```js
        const file = {
          filename: 'test.pdf',
          data: fileBuffer
        };

        let messageParams = {
          from: "Excited User <mailgun@sandbox-123.mailgun.org>",
          to: ["test@example.com"],
          subject: "Test subject",
          text: "Hello here is a file in the attachment",
          attachment: file
        };

        const res = await mg.messages.create(DOMAIN, messageParams);
      ```
  Promise returns:

  ```js
  {
    id: '<20151025002517.117282.79817@sandbox-123.mailgun.org>',
    message: 'Queued. Thank you.'
  }
  ```

### Templates

  Mailgun’s templates uses a fork of the very popular template engine [handlebars](https://handlebarsjs.com/).

  To provide values for a substitution you need to use 'h:X-Mailgun-Variables' property in the message description.

  Make sure that this property is a JSON string like:
  ```js
  JSON.stringify({
    "title": "A title",
    "body": "The body"
  })
  ```

  You can find few examples of how to use templates below.
- Providing values for **title** and **slug** variables to render in template
  ```js
    ...
    const {
      title,
      slug,
    } = someDataSource;

    const mailgunData = {
      from: 'mailer@example.com>',
      to: 'recipient@example.com',
      subject: `Email ${title}`,
      template: 'name-of-the-template-you-made-in-mailgun-web-portal',
      'h:X-Mailgun-Variables': JSON.stringify({ // be sure to stringify your payload
        title,
        slug,
      }),
      'h:Reply-To': 'reply-to@example.com',
    };

    try {
      const response = await mailgun.messages.create(DOMAIN_NAME, mailgunData);
    ...
  ```

- Providing an array of objects to render them in the template
  ```JS
    ...
    const mailgunData = {
      from: 'mailer@example.com>',
      to: 'recipient@example.com',
      subject: `Email ${title}`,
      template: 'name-of-the-another-template-you-made-in-mailgun-web-portal',
      'h:X-Mailgun-Variables': JSON.stringify({
      "arrayItems": [
          {
              "question": "test_question",
              "answer": "test_answer"
          },
          {
              "question": "test_question",
              "answer": "test_answer"
          }
      ]})
    };
    try {
      const response = await mailgun.messages.create(DOMAIN_NAME, mailgunData);
    ...
  ```

### Recipient Variables

  [Docs](https://documentation.mailgun.com/en/latest/user_manual.html#batch-sending)

  Recipient Variables are custom variables that you define, which you can then reference in the message body. They give you the ability to send a custom message to each recipient while still using a single API Call.

  ```JS
  ...
  const mailgunData = {
      from: 'Example.com Mailer <mailer@mailer.example.com>',
      to: ['me@example.com', 'you@example.com'],
      subject: 'Recipient - %recipient.title%',
      html: 'Here\'s %recipient.title% and <a href="%recipient.link%">link</a>',
      'recipient-variables': JSON.stringify({
        'me@example.com': {
          title: 'Me',
          link: 'href-var',
        },
        'you@example.com': {
          title: 'You',
          link: 'slug-recipient-var-c',
        },
      }),
    };

    try {
      const response = await mailgun.messages.create(DOMAIN_NAME, mailgunData);
  ...
  ```

### Domains

- #### list

  `mg.domains.list(query)` - [api docs](https://documentation.mailgun.com/en/latest/api-domains.html)

  Example:

  ```js
  mg.domains.list()
    .then(domains => console.log(domains)) // logs array of domains
    .catch(err => console.error(err)); // logs any error
  ```

  Promise returns: array of Domain instances

  ```JS
  [{
    created_at: 'Sun, 19 Oct 2014 18:49:36 GMT',
    name: 'testing.example.com',
    receiving_dns_records: null,
    require_tls: true,
    sending_dns_records: null,
    skip_verification: true,
    smtp_login: 'postmaster@testing.example.com',
    smtp_password: 'password',
    spam_action: 'disabled',
    state: 'unverified',
    type: 'custom',
    wildcard: true
  }]
  ```

  Query data may have next properties:

  | Property | Description                                           |
  |:----------|:------------------------------------------------------|
  | limit     | Maximum number of records to return. (100 by default) |
  | skip      | Number of records to skip. (0 by default)             |

- #### get

  `mg.domains.get(domain)`

  Example:

  ```JS
  mg.domains.get('testing.example.com')
    .then(domains => console.log(domains)) // logs domain object
    .catch(err => console.error(err)); // logs any error
  ```

  Promise returns: Domain instance

  ```JS
  {
    created_at: 'Sun, 19 Oct 2014 18:49:36 GMT',
    name: 'testing.example.com',
    receiving_dns_records: [{
        "name": "testing.example.com",
        "record_type": "TXT",

## Navigation thru lists
  Most of the methods that return items in a list support pagination.
  There are two ways to receive part of the list:
  1. Provide properties 'limit' and 'page' in the query.
  This way uses more frequently in the SDK and works for the next methods:
  - mg.domains.domainTags.list()
  - mg.domains.domainTemplates.list()
  - mg.domains.domainTemplates.listVersions()
  - mg.events.get()
  - mg.lists.list()
  - mg.lists.members.listMembers()
  - mg.validate.list()
  - mg.suppressions.list()

    The general idea is that after you made the first call with a limit property in the query you will receive a response with a property called pages in it. This property implements the next interface:

    ```TS
    {
        previous: {
            id: string;
            page: string;
            iteratorPosition: string | undefined;
            url: string
        };
        first: {
            id: string;
            page: string;
            iteratorPosition: string | undefined;
            url: string
        };
        last: {
            id: string;
            page: string;
            iteratorPosition: string | undefined;
            url: string
        };
        next: {
            id: string;
            page: string;
            iteratorPosition: string | undefined;
            url: string
        };
    }
    ```
    To receive the next page you need to add the page property to the query argument. This property should contain a string value from 'page' property in response.pages.(previous/first/last/next).

    Example:
    ```Js
    // first call
    const listMembers = await mg.lists.members.listMembers('your_mailing_list', { limit: 2 });

    /* response
    {
      items: [
        {
          address: 'test-0@example.com',
          name: 'test name 0',
          subscribed: true,
          vars: [Object]
        },
        {
          address: 'test-1@example.com',
          name: 'test name 1',
          subscribed: true,
          vars: [Object]
        }
      ],
      pages: {
        first: {
          id: 'first',
          page: '?page=first&limit=2',
          iteratorPosition: undefined,
          url: 'https://your_domain/v3/lists/your_mailing_list/members/pages?page=first&limit=2'
        },
        last: {
          id: 'last',
          page: '?page=last&limit=2',
          iteratorPosition: undefined,
          url: 'https://your_domain/v3/lists/your_mailing_list/members/pages?page=last&limit=2'
        },
        next: {
          id: 'next',
          page: '?page=next&address=test-1%40example.com&limit=2',
          iteratorPosition: 'test-1@example.com',
          url: 'https://your_domain/v3/lists/your_mailing_list/members/pages?page=next&address=test-1%40example.com&limit=2'
        },
        previous: {
          id: 'previous',
          page: '?page=prev&address=test-0%40example.com&limit=2',
          iteratorPosition: 'test-0@example.com',
          url: 'https://your_domain/v3/lists/your_mailing_list/members/pages?page=prev&address=test-0%40example.com&limit=2'
        }
      }
    }
    */
    // second call
    const listMembers = await mg.lists.members.listMembers(
        'your_mailing_list',
        {
          limit: 2,
          page: '?page=next&address=test-1%40example.com&limit=2'
        }
      );

    /* response
    {
      items: [
        {
          address: 'test-2@example.com',
          name: 'test name 2',
          subscribed: true,
          vars: [Object]
        },
        {
          address: 'test-3@example.com',
          name: 'test name 3',
          subscribed: true,
          vars: [Object]
        }
      ],
      pages: {
        first: {
          id: 'first',
          page: '?page=first&limit=2',
          iteratorPosition: undefined,
          url: 'https://your_domain/v3/lists/your_mailing_list/members/pages?page=first&limit=2'
        },
        last: {
          id: 'last',
          page: '?page=last&limit=2',
          iteratorPosition: undefined,
          url: 'https://your_domain/v3/lists/your_mailing_list/members/pages?page=last&limit=2'
        },
        next: {
          id: 'next',
          page: '?page=next&address=test-3%40example.com&limit=2',
          iteratorPosition: 'test-3@example.com',
          url: 'https://your_domain/v3/lists/your_mailing_list/members/pages?page=next&address=test-3%40example.com&limit=2'
        },
        previous: {
          id: 'previous',
          page: '?page=prev&address=test-2%40example.com&limit=2',
          iteratorPosition: 'test-2@example.com',
          url: 'https://your_domain/v3/lists/your_mailing_list/members/pages?page=prev&address=test-2%40example.com&limit=2'
        }
      }
    }
    */
    ```
    2. The second option of navigation is to provide properties 'limit' and 'skip' in the query. This way uses only in a few places for now:
      - mg.domains.list()
      - mg.domains.domainCredentials.list()
      - mg.routes.list()
      - mg.webhooks.list()
    The main idea here is quite simple you just need to provide how many records from the start of a list you want to skip and how many to receive. You can do it using the query parameter in each method.
    Example:
    ```js
    const listDomainCredentials = await client.domains.domainCredentials.list(
    'your_domain_name',
    {
      skip: 10,
      limit: 1
    }
    );
    ```

For this demo to work, you'll need to install and run `http-proxy` locally. Install it with:

```sh
npm install -g http-proxy
```

Then run the following command from the mailgun-js directory:

```sh
http-server -p 4001 --proxy="https://api.mailgun.net"
```

Demo should be up and running at http://0.0.0.0:4001/examples/

# Development

## Requirements

- Requires node.js >= 4.x

Install node dependencies with:

```sh
npm install
```

## Build
Build for dev purposes(without minimizing)
```sh
npm run build
```
Build for release purposes(include minimizing)
```sh
npm run build:release
```

## Merging changes

Before PR merge check that commits info will be correctly added to the CHANGELOG.md file:
'npm run release -- --dry-run'

> CI process isn't working currently, so please manually run ```npm run test```

## Tests

```sh
npm run tests
```

Watch tests with

```sh
npm run watch-tests
```

To test new functionality locally using ```npm link``` please use npm script ```npm run link```.
This is needed for correct exporting d.ts files.

## Release Process

Releases occur after feature branches have been tested and merged into master.

First, checkout master and pull the latest commits.

```sh
git checkout master
git pull
```

Next, run ```npm run release```.

After that, `cd ./dist` and then run ```npm login``` and ```npm publish``` to publish changes on npm.
