Module: MJML to HTML via CLI

[AAD Web Team]

Hello,

We have recently open-sourced our module MJML to HTML via CLI. A module that converts MJML email templates to HTML using a locally installed MJML CLI compiler.

Unlike other ProcessWire MJML solutions that rely on the hosted MJML API service, this module performs compilation directly on your web server using a compatible MJML CLI compiler such as MRML. This provides a fully self-hosted solution with no external API dependencies, network requests, usage limits, or third-party service requirements.

This module is best used in conjunction with the ProMailer module for easy sending of emails directly from ProcessWire.

Why use this module?

• Fully self-hosted MJML compilation
• No dependency on the MJML API service
• No API keys or external accounts required
• Works in environments with restricted outbound internet access
• Faster rendering when using native compilers such as MRML
• Ideal for organisations with security, privacy, or compliance requirements

Requirements

• PHP 7.3+
• ProcessWire 3.0.244+
• Any MJML compatible CLI compiler (available MJML compiler ports)

See more info in the repository on GitHub.

Let us know if you have any issues or suggestions - otherwise, happy (responsible) emailing! 🙂
