MjmlBundle

Bundle to use MJML 3 and 4 with Symfony >= 3.

Installation

Applications that use Symfony Flex

Open a command console, enter your project directory and execute:

$ composer require notfloran/mjml-bundle

Applications that don't use Symfony Flex

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ composer require notfloran/mjml-bundle

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the app/AppKernel.php file of your project:

// app/AppKernel.php

// ...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = [
            // ...
            new NotFloran\MjmlBundle\MjmlBundle(),
        ];

        // ...
    }

    // ...
}

Renderer

The default renderer is binary, which uses the official MJML Node.js implementation.

The mjml-php (PHP extension) renderer is also available as an alternative. It is based on MRML, a third-party Rust reimplementation of MJML.

Binary

Install MJML

$ npm install mjml

Then you need to update the configuration:

# config/packages/mjml.yaml
mjml:
  renderer: binary # default: binary
  options:
    binary: '%kernel.project_dir%/node_modules/.bin/mjml' # default: mjml
    node: '/Users/user/.nvm/versions/node/v10.16.0/bin/node' # default: null
    minify: true # default: false
    validation_level: skip # default: strict. See https://mjml.io/documentation/#validating-mjml

The node option is there for those who have problems with $PATH, see #35.

Note that each render spawns a new Node.js process, which may impact performance in high-volume scenarios.

mjml-php

Install mjml-php, a PHP extension that embeds MRML, the MJML rendering engine written in Rust, so that you can render MJML templates directly from PHP without shelling out to a CLI tool.

Then you need to update the configuration:

# config/packages/mjml.yaml
mjml:
  renderer: mjml_php

Custom

First you must create a class which implements NotFloran\MjmlBundle\Renderer\RendererInterface, then declare it as a service.

And finally you have to change the configuration:

# config/packages/mjml.yaml
mjml:
    renderer: 'service'
    options:
        service_id: 'App\Mjml\MyCustomRenderer'

PHP Config

If you're using symfony 5 and want to configure this bundle with PHP files instead of YAML:

// config/packages/mjml.php
<?php declare(strict_types=1);

use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $configurator): void
{
    $configurator->extension('mjml', [
        'renderer' => 'binary',
        'options' => [
            'binary' => '%kernel.project_dir%/node_modules/.bin/mjml',
            'minify' => true,
            'validation_level' => 'skip'
        ]
    ]);
};

API

The bundle has no official integration with the MJML API.

You can create your own integration by using juanmiguelbesada/mjml-php and following this gist : https://gist.github.com/notFloran/ea6bab137be628f6a0c19054e08e6906.

Usage

Use "mjml" twig tag

{# mail/example.mjml.twig #}
{% block email_content %}
    {% mjml %}
    <mjml>
        <mj-body>
                <mj-section>
                    <mj-column>

                        <mj-image width="100px" src="https://mjml.io/assets/img/logo-small.png"></mj-image>

                        <mj-divider border-color="#F45E43"></mj-divider>

                        <mj-text font-size="20px" color="#F45E43" font-family="helvetica">
                            Hello {{ name }} from MJML and Symfony
                        </mj-text>

                    </mj-column>
                </mj-section>
        </mj-body>
    </mjml>
    {% endmjml %}
{% endblock %}

public function sendEmail(MailerInterface $mailer)
{
    // The MJMl body is rendered by the mjml tag in the twig file
    $htmlBody = $this->renderView('templates/mail/example.mjml.twig', ['name' => 'Floran']);

    $email = (new Email())
        ->from('my-app@example.fr')
        ->to('me@example.fr')
        ->subject('Hello from MJML!')
        ->html($htmlBody);

    $mailer->send($email);

    // ...
}

Use "mjml" service

{# templates/mail/example.mjml.twig #}
<mjml>
    <mj-body>
            <mj-section>
                <mj-column>

                    <mj-image width="100px" src="https://mjml.io/assets/img/logo-small.png"></mj-image>

                    <mj-divider border-color="#F45E43"></mj-divider>

                    <mj-text font-size="20px" color="#F45E43" font-family="helvetica">
                        Hello {{ name }} from MJML and Symfony
                    </mj-text>

                </mj-column>
            </mj-section>
    </mj-body>
</mjml>

use NotFloran\MjmlBundle\Renderer\RendererInterface;

// ...

public function sendEmail(MailerInterface $mailer, RendererInterface $mjml)
{
    $mjmlBody = $this->renderView('templates/mail/example.mjml.twig', ['name' => 'Floran']);
    $htmlBody = $mjml->render($mjmlBody);

    $email = (new Email())
        ->from('my-app@example.fr')
        ->to('me@example.fr')
        ->subject('Hello from MJML!')
        ->html($htmlBody);

    $mailer->send($email);

    // ...
}

SwiftMailer integration

❗ This integration is deprecated and will be removed in the next major version.

Declare the following service:

NotFloran\MjmlBundle\SwiftMailer\MjmlPlugin:
    tags: [swiftmailer.default.plugin]

Create a SwiftMailer message with a MJML body (without {% mjml %}) and with text/mjml as content-type:

$message = (new \Swift_Message('Hello Email'))
    ->setFrom('send@example.com')
    ->setTo('recipient@example.com')
    ->setBody(
        $this->renderView('mail/example.mjml.twig'),
        'text/mjml'
    );

$mailer->send($message);

The plugin will automatically render the MJML body and replace the body with the rendered HTML.

In the case where a spool is used: the MJML content is save in the spool and render when the spool is flushed.
