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

Via NPM:


npm install -g mjml

Via... click:

### Inside NodeJs

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

console.log(htmlOutput);

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
