Example of attaching a file stream

In this case we will pass a file stream as an attachment. Note the structure of the attachment object, every property is required by mailgun in order to send the attachment. Omitting properties will cause mailgun to drop your attachment, the message will be delivered though

  var path = require('path');
  var mime = require('mime');
  var file = path.resolve('../client/images/an-image.jpg');
  var fileStream = fs.createReadStream(file);
  var fileStat = fs.statSync(file);
  var attachment = {
      data: fileStream,
      filename: path.basename(file),
      knownLength: fileStat.size,
      contentType: mime.lookup(file)//REQUIRED, by omitting this, mailgun will not send your attachment
  };

  loopback.Email.send({
      to: "to@to.com",
      from: "from@from.com",
      subject: "subject",
      text: "text message",
      html: "html <b>message</b>",
      attachments : [attachment]
  })
  .then(function(response){})
  .catch(function(err){});

###quick note on attachments Refer to Mailgun documentation on limitations concerning attachments. The attachments property can be either an array of strings or buffers or a string.
