Installation

npm install email-templates

Quick Start

  1. Install the module for your respective project npm install email-templates.
  2. Create a folder called templates inside your root directory (or elsewhere).
  3. For each of your templates, respectively name and create a folder inside the templates folder.
  4. Add the following files inside the template's folder:
  5. You may use the include directive from ejs (for example, to include a common header or footer). See the /examples folder for details.
  6. Utilize one of the examples below for your respective email module and start sending beautiful emails!

Templating Language Options (e.g. EJS Custom Tags)

Want to use different opening and closing tags instead of the EJS's default <% and %>?.

...
emailTemplates(templatesDir, { open: '{{', close: '}}' }, function(err, template) {
...

NOTE: You can also pass other options from EJS's documentation.

Examples

Basic

Render a template for a single email or render multiple (having only loaded the template once).

var path           = require('path')
  , templatesDir   = path.join(__dirname, 'templates')
  , emailTemplates = require('email-templates');

emailTemplates(templatesDir, function(err, template) {

  // Render a single email with one template
  var locals = { pasta: 'Spaghetti' };
  template('pasta-dinner', locals, function(err, html, text) {
    // ...
  });

  // Render multiple emails with one template
  var locals = [
    { pasta: 'Spaghetti' },
    { pasta: 'Rigatoni' }
  ];
  var Render = function(locals) {
    this.locals = locals;
    this.send = function(err, html, text) {
      // ...
    };
    this.batch = function(batch) {
      batch(this.locals, this.send);
    };
  };
  template('pasta-dinner', true, function(err, batch) {
    for(var user in users) {
      var render = new Render(users[user]);
      render.batch(batch);
    }
  });

});

Nodemailer

var path           = require('path')
  , templatesDir   = path.resolve(__dirname, '..', 'templates')
  , emailTemplates = require('email-templates')
  , nodemailer     = require('nodemailer');

emailTemplates(templatesDir, function(err, template) {

  if (err) {
    console.log(err);
  } else {

    // ## Send a single email

    // Prepare nodemailer transport object
    var transport = nodemailer.createTransport("SMTP", {
      service: "Gmail",
      auth: {
        user: "some-user@gmail.com",
        pass: "some-password"
      }
    });

    // An example users object with formatted email function
    var locals = {
      email: 'mamma.mia@spaghetti.com',
      name: {
        first: 'Mamma',
        last: 'Mia'
      }
    };

    // Send a single email
    template('newsletter', locals, function(err, html, text) {
      if (err) {
        console.log(err);
      } else {
        transport.sendMail({
          from: 'Spicy Meatball <spicy.meatball@spaghetti.com>',
          to: locals.email,

          }
        });

    });


    // ## Send a batch of emails and only load the template once

    // Prepare nodemailer transport object
    var transportBatch = nodemailer.createTransport("SMTP", {
      service: "Gmail",
      auth: {
        user: "some-user@gmail.com",
        pass: "some-password"
      }
    });

    // An example users object
    var users = [
      {
        email: 'pappa.pizza@spaghetti.com',

          last: 'Geppetto'
        }
      }
    ];

    // Custom function for sending emails outside the loop
    //
    // NOTE:
    //  We need to patch postmark.js module to support the API call
    //  that will let us send a batch of up to 500 messages at once.
    //  (e.g. <https://github.com/diy/trebuchet/blob/master/lib/index.js#L160>)

Postmark

This example utilizes Postmark.js.

NOTE: Did you know nodemailer can also be used to send SMTP email through Postmark? See this section of their Readme for more info.

For more message format options, see this section of Postmark's developer documentation section.

var path           = require('path')
  , templatesDir   = path.resolve(__dirname, '..', 'templates')

emailTemplates(templatesDir, function(err, template) {

  if (err) {
    console.log(err);
  } else {

    // ## Send a single email

    // An example users object with formatted email function
    var locals = {
      email: 'mamma.mia@spaghetti.com',
      name: {
        first: 'Mamma',
