Introduction

MJML is a markup language designed to reduce the pain of coding a responsive email. Its semantic syntax makes it easy and straightforward while its rich standard components library fastens your development time and lightens your email codebase. MJML’s open-source engine takes care of translating the MJML you wrote into responsive HTML.

Installation

Requirements

Node >= 4.2.x

Via NPM:

Command line

import { mjml2html } from 'mjml'

/*
  Compile an mjml string
*/
const htmlOutput = mjml2html(`<mj-body>
  <mj-section>
    <mj-column>
      <mj-text>
        Hello World!
      </mj-text>

console.log(htmlOutput)

In your browser

<html>
  <head>

    <script>
      /*
        Compile an mjml string
      */
      var htmlOutput = mjml.mjml2html('<mj-body>' +
        '<mj-section>' +
          '<mj-column>' +
            '<mj-text>' +
              'Hello World!' +

      '</mj-body>')

      /*

      console.log(htmlOutput)
    </script>
  </head>
  <body>

  </body>
</html>

Create your component

Issue the following in your terminal

$> mjml --init-component <name of your component>

# If your component cannot contain anything else than text:
$> mjml --init-component <name of you component> -e

# It means nothing inside it will be parsed by the mjml engine.

It will create a basic component template in a .js file. Follow the instructions provided in the file and read more about custom components in the documentation
