MRML

Introduction

This project is a reimplementation of the nice MJML markup language in Rust.

How to use it in the cli

# installing mrml-cli
cargo install --locked mrml-cli
# using it 
mrml-cli path/to/template.mjml validate
mrml-cli path/to/template.mjml render
mrml-cli path/to/template.mjml format-json --pretty
mrml-cli path/to/template.json format-mjml --pretty
# getting some help
mrml-cli --help

Why?

• A Node.js server rendering an MJML template takes around 20 MB of RAM at startup and 130 MB under stress test. In Rust, less than 1.7 MB at startup and a bit less that 3 MB under stress test. The Rust version can also handle twice as many requests per second. You can perform the benchmarks by running bash script/run-bench.sh.
• The JavaScript implementation cannot be run in the browser; the Rust one (and WebAssembly one) can be.
