Adding compile plugins to email transports in the Strongloop loopback boot script

email.js

// server/boot/email.js
var htmlToText = require('nodemailer-html-to-text').htmlToText;

var path = require('path');

function templatePath (template) {
  // this looks for templates in the root 'templates' folder where other email templates like verify.ejs exist
  return path.join(__dirname, '..', '..', 'templates', template);
}

module.exports = function(app) {
  var Email = app.models.Email;

  // assign our compile plugin to all the transports we find
  app.dataSources.MyMail.connector.transports.forEach(function (transport) {
    transport.use('compile', htmlToText());
  });

  Email.inviteUser = function (options, next) {
    var template = app.loopback.template(templatePath('inviteUser.ejs'));
    var data = { to       : options.to,
                 subject  : options.subject,
                 html     : template(options) };
    Email.send(data, next);
  };
