MJML is a markup language designed to reduce the pain of coding a responsive email. Our mjml-php package can convert MJML to HTML.

Here's an example of how to use our package:

use Spatie\Mjml\Mjml;

$mjml = <<<'MJML'
    <mjml>
      <mj-body>
        <mj-section>
          <mj-column>
            <mj-text invalid-attribute>Hello World</mj-text>
          </mj-column>
        </mj-section>
      </mj-body>
    </mjml>
    MJML;

$html = Mjml::new()->toHtml($mjml);

The returned HTML will look like the HTML in this snapshot file (it's a bit too large to inline in this readme). Most email clients will be able to render this HTML perfectly.

Installation

You can install the package via composer:

composer require spatie/mjml-php

In your project, or on your server, you must have the JavaScript package mjml installed.

npm install mjml

... or Yarn.

yarn add mjml

Make sure you have installed Node 16 or higher.

Usage

The easiest way to convert MJML to HTML is by using the toHtml() method.

use Spatie\Mjml\Mjml;

// let's assume $mjml contains the MJML you want to convert

$html = Mjml::new()->toHtml($mjml);

If the MJML could not be converted at all a Spatie\Mjml\Exceptions\CouldNotRenderMjml exception will be thrown.

Using convert()

The toHtml() method will just return the converted HTML. There's also a convert() method that will return an instance of Spatie\Mjml\MjmlResult that contains the converted HTML and some metadata.

use Spatie\Mjml\Mjml;

// let's assume $mjml contains the MJML you want to convert

$result = Mjml::new()->convert($mjml); // returns an instance of Spatie\Mjml\MjmlResult

On the returned instance of Spatie\Mjml\MjmlResult you can call the following methods:

  • html(): returns the converted HTML
  • array(): returns a structured version of the given MJML
  • hasErrors(): returns a boolean indicating if there were errors while converting the MJML
  • errors(): returns an array of errors that occurred while converting the MJML

The errors() method returns an array containing instances of Spatie\Mjml\MjmlError. Each Spatie\Mjml\MjmlError has the following methods:

  • line(): returns the line number where the error occurred
  • message(): returns the error message
  • formattedMessage(): returns the error message with the line number prepended
  • tagName(): returns the name of the tag where the error occurred

Customizing the rendering

There are various methods you can call on the Mjml class to customize the rendering. For instance the minify() method will minify the HTML that is returned.

use Spatie\Mjml\Mjml;

// let's assume $mjml contains the MJML you want to convert
$minifiedHtml = Mjml::new()->minify()->toHtml($mjml);

These are all the methods you can call on the Mjml class:

  • minify(): minify the HTML that is returned
  • beautify(): beautify the HTML that is returned
  • hideComments(): hide comments in the HTML that is returned
  • validationLevel(ValidationLevel $validationLevel): set the validation level to strict, soft or skip

Instead of using these dedicated methods, you could opt to pass an array with options as the second argument of the toHtml or convert method. You can use any of the options that are mentioned in the MJML documentation for Node.js.

use Spatie\Mjml\Mjml;

// let's assume $mjml contains the MJML you want to convert
$minifiedHtml = Mjml::new()->minify()->toHtml($mjml, [
    'beautify' => true,
    'minify' => true,
]);

Validating MJML

You can make sure a piece of MJML is valid by using the canConvert() method.

use Spatie\Mjml\Mjml;

Mjml::new()->canConvert($mjml); // returns a boolean

If true is returned we'll be able to convert the given MJML to HTML. However, there may still be some errors while converting the MJML to HTML. These errors are not fatal and the MJML will still be converted to HTML. You can see these non-fatal errors when calling errors() on the MjmlResult instance that is returned when calling convert.

You can use canConvertWithoutErrors to make sure the MJML is both valid and that there are no non-fatal errors while converting it to HTML.

use Spatie\Mjml\Mjml;

Mjml::new()->canConvertWithoutErrors($mjml); // returns a boolean

Specifying the path to nodejs executable

By default, the package itself will try to determine the path to the node executable. If the package can't find a path, you can specify a path in the environment variable MJML_NODE_PATH

MJML_NODE_PATH=/home/user/.nvm/versions/node/v20.11.0/bin

Sidecar

This package also supports running through Sidecar in Laravel projects.

To use the ->sidecar() method, a few extra steps are needed:

Install the Sidecar package:

composer require spatie/mjml-sidecar

Register the MjmlFunction in your sidecar.php config file.

/*
 * All of your function classes that you'd like to deploy go here.
 */
'functions' => [
    \Spatie\MjmlSidecar\MjmlFunction::class,
],

Deploy the Lambda function by running:

php artisan sidecar:deploy --activate

See the Sidecar documentation for details.
