Getting Started

Install this module.

npm install @danfebooks/sails-service-mailer

Then import it in your service and create mailer instance.

// api/services/MailerService.js
import MailerService from '@danfebooks/sails-service-mailer';

// Note: If you are using commonjs `require`, then please use
const MailerService = require('@danfebooks/sails-service-mailer').default;


export default MailerService('sendmail', {
  from: '[email protected]',
  subject: 'Hello, there',
  provider: {
    path: '/usr/bin/sendmail'
  }
});

// api/controllers/MailController.js
export default {
  send: function(req, res) {
    MailerService
      .send({
        to: req.param('to'),
        text: 'And of course, Hello World!'
      })
      .then(res.ok)
      .catch(res.negotiate);
  }
};

Configuration

There is two kind of configuration - provider configuration and mail configuration.

When you instantiate new instance of mailer, in configuration object you can add provider object. This object will send directly to one of nodemailer transports.

And all keys that don't belongs to provider will send directly to sendMail function.

So basic configuration can be:

let mailer = MailerService('direct', {
  from: '[email protected]' // this will go to sendMail,
  provider: { // this will go to nodemailer.createTransport
    name: 'some.mx-server.com'
  }
});

Each of available options you can find in nodemailer transport repositories or a little bit below in examples.

• Mail options you can find here.
• Provider options you can find in appropriate repository of nodemailer transports.

API

Each of Mailer instances has only one method:

send(config)

config - Configuration object with mail options like from, to, etc... It will mix up to the pre-defined config. All allowed options for this object you can find here.

Returns Promise.

Examples

All of this examples contains all the provider configuration keys. And most of them is optional.

DirectMailer

let direct = MailerService('direct', {
  from: '[email protected]',
  provider: {
    name: '<MX_HOSTNAME>', // hostname to be used when introducing the client to the MX server
    debug: false // if true, the connection emits all traffic between client and server as `log` events
  }
});

SendGridMailer

let sendGrid = MailerService('sendgrid', {
  from: '[email protected]',
  provider: {
    auth: {
      api_key: '<SENDGRID_APIKEY>' // SendGrid API KEY
    }
  }
});

SendMailMailer

let sendmail = MailerService('sendmail', {
  from: '[email protected]',
  provider: {
    path: '/usr/bin/sendmail', // path to the sendmail command
    args: [] // an array of extra command line options to pass to the `sendmail` command
  }
});

SESMailer

let ses = MailerService('ses', {
  from: '[email protected]',
  provider: {
    ses: {}, // instantiated AWS SES object with new AWS.SES()
    accessKeyId: 'MY_KEY', // AWS access key
    secretAccessKey: 'MY_SECRET', // AWS secret key
    sessionToken: '', // Session token
    region: '', // Specify the region to send the service request
    httpOptions: {}, // A hash of options to pass to the low-level AWS HTTP request
    rateLimit: 5 // Specify the amount of messages can be sent in 1 second
  }
});

SMTPMailer

let smtp = MailerService('smtp', {
  from: '[email protected]',
  provider: {
    port: 25, // The port to connect to
    host: 'localhost', // The hostname to connect to
    secure: false, // Defines if the connection should use SSL
    auth: { // Defines authentication data
      user: '', // Username
      pass: '', // Password
      xoauth2: '' // OAuth2 access token
    },
    ignoreTLS: false, // Turns off STARTTLS support if true
    name: '', // Options hostname of the client
    localAddress: '', // Local interface to bind to for network connections
    connectionTimeout: 2000, // How many ms to wait for the connection to establish
    greetingTimeout: 2000, // How many ms to wait for the greeting after connection
    socketTimeout: 2000, // How many ms of inactivity to allow
    debug: false, // If true, the connection emits all traffic between client and server as `log` events
    authMethod: 'PLAIN', // Defines preferred authentication method
    tls: {} // Defines additional options to be passed to the socket constructor
  }
});

StubMailer

let stub = MailerService('stub', {
  from: '[email protected]',
  provider: {
    error: new Error('Invalid recipient') // If you want that sending will fail and return error
  }
});
