The SendGrid Mailer App

The SendGrid mailer app provides a Foxx script and Foxx.queues job type for sending transactional emails with SendGrid.

Note: Version 2.0.0 and higher require ArangoDB 2.6 or later to work correctly.

Examples

First add this app to your dependencies:

{
  ...
  "dependencies": {
    "mailer": "mailer-sendgrid:^2.0.0"
  }
  ...
}

Once you've configured both apps correctly, you can use it like this:

var Foxx = require('org/arangodb/foxx');
var queue = Foxx.queues.get('default');

queue.push(applicationContext.dependencies.mailer, {
    from: '[email protected]',
    to: '[email protected]',
    subject: 'Termination',
    html: '<blink>YOU ARE FIRED!</blink>'
});

Configuration

This app has the following configuration options:

• apiUser: Your SendGrid API user. This is the same username used to log into your SendGrid account.
• apiKey: Your SendGrid API key. This is the same password used to log into your SendGrid account.
• maxFailures (optional): The maximum number of times each job will be retried if it fails. Default: 0 (don't retry).

Job Data

For full documentation of all job data options supported by SendGrid see the official SendGrid API documentation.

You can specify an option multiple times by passing an array as the option's value.

Attachments

If you want to send attachments, you need to pass them as objects with the following properties:

• content: the attachment's base64-encoded content.
• name: the name of the attachment that will be used in the e-mail.
• type (optional): the attachment's MIME type. Default: application/octet-stream

If you want to reference attachments in the message's html you can specify content IDs by passing an object mapping file names to content IDs.

Examples

queue.push(applicationContext.dependencies.mailer, {
    // ...
    html: '<a href="cid:ii_139db99fdb5c3704">hello world</a>',
    files: {
        content: 'SGVsbG8gV29ybGQh',
        name: 'hello_world.txt',
        type: 'text/plain'
    },
    content: {
        'hello_world.txt': 'ii_139db99fdb5c3704'
    }
});
