email-templates

node-email-templates ^0.0.5

Node.js module for rendering beautiful emails with ejs templates and email-friendly inline CSS using juice.

v0.0.5:

• Added support for an optional zlib compression type (e.g. you can return compressed html/text buffer for db storage)

...
template('newsletter', locals, 'deflateRaw', function(err, html, text) {
  // The `html` and `text` are buffers compressed using zlib.deflateRaw
  // <http://nodejs.org/docs/latest/api/zlib.html#zlib_zlib_deflateraw_buf_callback>
  // **NOTE**: You could also pass 'deflate' or 'gzip' if necessary, and it works with batch rendering as well
})
...

v0.0.4 (with bug fix for 0.0.3):

• Removed requirement for style.css and text.ejs files with compatibility in node v0.6.x to v0.8.x (utilizes path.exists vs. fs.exists respectively).

Installation

Unix/OS X

npm install email-templates

Windows

npm install email-templates-windows

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:
   • html.ejs - html + ejs version of your email template (required)
   • text.ejs - text + ejs version of your email template (optional)
   • style.css - stylesheet for the template, which will render html.ejs with inline CSS (optional)
5. Utilize one of the examples below for your respective email module and start sending beautiful emails!

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.

Usage

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);
    }
  });

});

Example with 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: "[e-mail]",
        pass: "some-password"
      }
    });

    // An example users object with formatted email function
    var locals = {
      email: '[e-mail]',
      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 <[e-mail]>',
          to: locals.email,
          subject: 'Mangia gli spaghetti con polpette!',
          html: html,
          // generateTextFromHTML: true,
          text: text
        }, function(err, responseStatus) {
          if (err) {

          } else {
            console.log(responseStatus.message);
          }
        });
      }
    });


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

    // Prepare nodemailer transport object
    var transportBatch = nodemailer.createTransport("SMTP", {
      service: "Gmail",
      auth: {
        user: "[e-mail]",
        pass: "some-password"

          first: 'Mister',
          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>)
    var Render = function(locals) {

            }
          });
        }

Example with Postmark App (utilizing 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')
