How to send message with nodemailer and email-templates?

Question

I try to send email with nodemailer and email-templates. Now I have example from here example email templates. But when I check this code, I have error a promise was rejected with a non-error: [object Undefined]

Help me please. This is my code

var nodemailer = require('nodemailer');
var EmailTemplate = require('email-templates').EmailTemplate;

exports.sendOne = function () {
var templatesDir = config.templatesDir;
var template = new EmailTemplate(path.join(templatesDir, 'hello.jade'))
var transport = nodemailer.createTransport({
    service: config.service,
    auth: config.auth
});

// An example users object with formatted email function
var locals = {
    email: '[email protected]',
    name: {
        first: 'Mamma',
        last: 'Mia'
    }
}

// Send a single email
template.render(locals, function (err, results) {
    if (err) {
        return console.error(err)
    }

    transport.sendMail({
        from: 'Spicy Meatball <[email protected]>',
        to: locals.email,
        subject: 'Mangia gli spaghetti con polpette!',
        html: results.html,
        text: results.text
    }, function (err, responseStatus) {
        if (err) {
            return console.error(err)
        }
        console.log(responseStatus.message)
    })
})

}

My error :

Tell me please how to fix this error? thanks!

UPDATE code

exports.sendOne = function () {
  var nodemailer = require("nodemailer");

  var transport = nodemailer.createTransport({
    service: "gmail",
    auth: {
      user: "[email protected]",
      pass: "123456",
    },
  });

  var EmailTemplate = require("email-templates").EmailTemplate;
  var path = require("path");

  var templateDir = path.join(__dirname, "templates", "hello");

  var myTemplate = new EmailTemplate(templateDir);

  var locals = {
    email: "[email protected]",
    name: {
      first: "Mamma",
      last: "Mia",
    },
  };

  myTemplate.render(locals, function (err, result) {
    // result.html
    // result.text
    if (err) {
      return console.error(err);
    }

    transport.sendMail(
      {
        from: "Spicy Meatball <[email protected]>",
        to: locals.email,
        subject: "Mangia gli spaghetti con polpette!",
        html: results.html,
        text: results.text,
      },
      function (err, responseStatus) {
        if (err) {
          return console.error(err);
        }
        console.log(responseStatus.message);
        return responseStatus; // return from status or as you need;
      }
    );
  });
};

I updated my code but now i have error { [Error: ENOENT: no such file or directory, stat '/path-to-my-project/templates/hello''] errno: -2, code: 'ENOENT', syscall: 'stat', path: '/path-to-my-project/templates/hello' }

I guess template rendering issue and you should return something from function (err, responseStatus){} for success

Here I assume hello.jade in templates folder and templates folder in root directory and ensure jade is using as template engine

can try it

var EmailTemplate = require('email-templates').EmailTemplate;
var path = require('path');

var templateDir = path.join(__dirname, 'templates', 'hello');

var myTemplate = new EmailTemplate(templateDir);
var locals = {
      email: '[email protected]',
      name: {
           first: 'Mamma',
           last: 'Mia'
      }
 }
myTemplate .render(locals , function (err, result) {
  // result.html 
  // result.text 
    if (err) {
       return console.error(err)
    }
    // check here what is showing in your result
    transport.sendMail({
        from: 'Spicy Meatball <[email protected]>',
        to: locals.email,
        subject: 'Mangia gli spaghetti con polpette!',
        html: results.html,
        text: results.text
     }, function (err, responseStatus) {
        if (err) {
            return console.error(err)
        }
        console.log(responseStatus.message)
        return responseStatus;// return from status or as you need;
    })
})

Updated: As far I guess it's not nodemailer related issue it's may be template rendering issue. can check by directory or by html page.
