Compile MJML at runtime without an external Node service/process. It is a Python wrapper for MRML (Rust port of MJML).
From MRML:
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.
All of that is without considering http transaction cost when using a node service or process.
Install from PyPI:
pip install mjml-pythonImport mjml2html and pass a string to compile:
from mjml import mjml2html
html = mjml2html('''
<mjml>
<mj-body>
<mj-section>
<mj-column>
<mj-image width="100px" src="/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 World</mj-text>
</mj-column>
</mj-section>
</mj-body>
</mjml>
