Installation

Install email-templates-v2 and the engines you wish to use by adding them to your package.json dependencies.

npm install --save email-templates-v2
# See https://www.npmjs.com/package/consolidate for a full list of available template engines
npm install -S [ejs|jade|nunjucks|handlebars|emblem|dust-linkedin] 

Quick Start

1. Install the module for your respective project:

   npm install --save email-templates-v2@2

2. Install the template engine you intend to use:

   • ejs@^2.0.0

   • jade@^1.0.0

   • nunjucks@^1.0.0

   • handlebars@^3.0.0

   • dust-linkedin@^2.0.0

   • less@^2.0.0

   • stylus@^0.51.0

   • styl@^0.2.0

   • node-sass@^3.0.0

   • See https://www.npmjs.com/package/consolidate for a full list

   npm install --save <engine>

3. For each of your email templates (e.g. a welcome email to send to users when they register on your site), respectively name and create a folder.

   mkdir templates/welcome-email

4. Add the following files inside the template's folder:

   • html.{{ext}} (required) - for html format of email
   • text.{{ext}} (optional) - for text format of email
   • style.{{ext}}(optional) - styles for html format
   • subject.{{ext}}(optional) - for subject of email

   See supported template engines for possible template engine extensions (e.g. .ejs, .jade, .nunjucks) to use for the value of {{ext}} above.

   You may prefix any file name with anything you like to help you identify the files more easily in your IDE. The only requirement is that the filename contains html., text., style., and subject. respectively.

5. You may use the include directive from ejs (for example, to include a common header or footer). See the /examples folder for details.

Template Engine Options

If your want to configure your template engine, just pass options.

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

new EmailTemplate(templateDir, { delimiter: '?' })

You can also directly modify the template engine

// ...
Handlebars.registerPartial('name', '{{name.first}} {{name.last}}')
Handlebars.registerHelper('capitalize', function (context) {
  return context.toUpperCase()
})
new EmailTemplate(templateDir)
// ...

You can also pass a juiceOptions object to configure the output from juice

new EmailTemplate(templateDir, {juiceOptions: {
  preserveMediaQueries: false,
  removeStyleTags: false
}})

You can check all the options in juice's documentation

Examples

Basic

Render a single template (having only loaded the template once).

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

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

var newsletter = new EmailTemplate(templateDir)
var user = {name: 'Joe', pasta: 'spaghetti'}
newsletter.render(user, function (err, results) {
  // result.html
  // result.text
})

var async = require('async')
var users = [
  {name: 'John', pasta: 'Rigatoni'},
  {name: 'Luca', pasta: 'Tortellini'}
]

async.each(users, function (user, next) {
  newsletter.render(user, function (err, results) {
    if (err) return next(err)
    // result.html
    // result.text
    // result.subject
  })
}, function (err) {
  //
})

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

var path           = require('path')
var templateDir   = path.join(__dirname, 'templates', 'pasta-dinner')
var EmailTemplate = require('email-templates').EmailTemplate

var template = new EmailTemplate(templateDir)
var users = [
  {
    email: '[email protected]',
    name: {
      first: 'Pappa',
      last: 'Pizza'
    }
  },
  {
    email: '[email protected]',
    name: {
      first: 'Mister',
      last: 'Geppetto'
    }
  }
]

var templates = users.map(function (user) {
  return template.render(user)
})

Promise.all(templates)
  .then(function (results) {
    console.log(results[0].html)
    console.log(results[0].text)
    console.log(results[0].subject)
    console.log(results[1].html)
    console.log(results[1].text)
    console.log(results[1].subject)
  })
