promisify nodemailer-smtp-transport

Hey, i try to get into bluebird. can you help me with wrapping nodemailer-smtp-transport? I am using koa and tried a lot but couldnt find the solution. Here is my code:

var nodemailer = require('nodemailer'); var smtpTransport = require('nodemailer-smtp-transport'); var Promise = require("bluebird");

exports.create = function*() {
  var transporter = nodemailer.createTransport(smtpTransport({
      host: 'smtp.myemailservice.de',
      port: 25,
      auth: {
          user: 'user',
          pass: 'pw'
      }
  }));

  var mailOptions = {
      from: 'Fred Foo ✔ <[e-mail]>', // sender address
      to: '[e-mail]', // list of receivers
      subject: 'Hello ✔', // Subject line
      text: 'Hello world ✔', // plaintext body
      html: 'mail conent'·
  };

  transporter.sendMail(mailOptions, function(error, info) {
      if (error) {
          this.body = error;
      } else {
        this.body = info.response;
      }
  });

};

I was also having the same problem some time ago. The code above is no longer valid. You have to use this:

var nodemailer = require('nodemailer')
var transport = Promise.promisifyAll(nodemailer.createTransport({ /* options */ }))

Note that if you are trying to use a transport mechanism that is not built-in, there is a small difference. Instead of passing an options object to the createTransport method, you pass the external transport directly like so:

// Example using the stub transport
var stubTransport = require('nodemailer-stub-transport')()
var transport = Promise.promisifyAll(nodemailer.createTransport(stubTransport))

nodemailer-smtp-transport is built-in to nodemailer (it’s the default transport) so you should need to install it separately. I typically only promisify the sendMail method:

var nodemailer = require('nodemailer')
var P = require('bluebird')

var transport = nodemailer(smtpTransportOpts)
var sendMail = P.promisify(transport.sendMail, transport)

sendMail(mailOpts)
  .then(handleRes)
  .catch(handleErr)

However you can promisify all the methods by using P.promisifyAll like such:

var transport = P.promisifyAll(nodemailer(smtpTransportOpts))

By default, bluebird gives the new promise aware methods Async suffixes so you’d use sendMail like this:

tranport.sendMailAsync(mailOpts)
  .then(handleRes)
  .catch(handleErr)
