email-builder-core-min

Email builder core for export into other projects.

This is a forked version of email-builder-core (https://github.com/Email-builder/email-builder-core) with some updates to it and one less perk.

This version does not include the litmus api, and has been updated to use Gulp 4.

Constructor

new EmailBuilder(options)

Example:

const EmailBuilder = require('email-builder-core-min');
const emailBuilder = new EmailBuilder({ encodeSpecialChars: true });

Options

The following options may support all available methods of EmailBuilder. However there some that are only needed for a particular method.

options.encodeSpecialChars Type: Boolean Default: false Supported Method(s): All

Encodes special characters to their HTML numerical form e.g. © --> ©

options.relativePath Type: String Default: '' Supported Method(s): emailBuilder.inlineCss

This option must be set when passing a Buffer or a String to the inlineCss method. That way it has a relative path to any css files. The path should be whatever directory your src file is in.

options.emailTest Type: Object Default: {} Properties: to, from, subject, nodemailer Supported Method(s): emailBuilder.sendEmailTest

The optional nodemailer property is an object that has transporter and defaults properties. These get passed to the nodemailer.createTransport() method. You can use transport plugins or play with the default SMTP options for the nodemailer.transporter property

Example:

  emailTest : {

  // Email to send to
  to : 'toEmail@email.com',

  // Email sent from
  from: 'fromEmail@email.com',

  // Your email Subject
  subject : 'Email Subject',

  // Optional
  nodemailer: {
    transporter: {
      service: 'gmail',
      auth: {
        user: 'gmailuser',
        pass: 'gmailpass'
      }
    },
    defaults: {}
  }
}

options.juice Type: Object Default: {} Supported Properties: extraCss, applyWidthAttributes, applyAttributesTableElements Supported Method(s): emailBuilder.inlineCss

View Juice options

options.cheerio Type: Object Default: {}

View Cheerio options.

Methods

All methods return a promise, the underlying promise library we use is Bluebird.

Methods can be used seperately, or chained together using the .then method.

If you're not familiar with promises, instead of using a callback, you chain a .then method to get the results.

emailBuilder.inlineCss(file/html/buffer)

Inlines css from embedded or external styles. It'll automatically remove any link or style tags unless one of the data attributes below are used.

Arguments

file - String containing path to file string - String of HTML buffer - Buffer of HTML

HTML data attributes There are two supported data attributes that you can apply to \<style> or \<link> tags that have special meaning:

data-embed

  • use on \<style> or \<link> tags if you want styles to be embedded in the \<head> of the final output. Does not inline css

data-embed-ignore

  • use on \<link> tags to preserve them in the \<head>. Does not inline or embed css

Example:

emailBuilder.inlineCss('path/to/file.html')
    .then(html => {
        console.log(html);
    });

emailBuilder.sendEmailTest(html)

Send email tests to yourself

Arguments

html - String/Buffer of HTML

Example:

const fs = require('fs');
const file = fs.readFileSync('path/to/file.html');
emailBuilder.sendEmailTest(file)
  .then(html => {
    console.log(html);
  });

};
const emailBuilder = new EmailBuilder(options);
const src = process.cwd() + '/input.html';

emailBuilder.inlineCss(src)
    .then(emailBuilder.sendEmailTest)
    .then(html => {
        // can write files here
        fs.writeFileSync(process.cwd() + '/out.html', html);
    })
    catch(err => {
        console.log(err);
