django-compressor-js 0.1.0

Transpile JavaScript without running an extra node.js process.

django-compressor-js

Instead of running an extra node.js process watching for changes in your Javascript, this precompiler for django-compressor will convert any ES6 code into ES5 automagically.

Install

1. pip install django-compressor-js
2. Add precompiler (text/es6 can be anything, but it has to match the script type in the template)

COMPRESS_PRECOMPILERS = (
    ("text/es6", "django_compressor_js.precompilers.BabelCompiler"),
)

3. Add to HTML template

{% compress js %}
	<script src="{% static 'js/test-es6-code.js' %}" type="text/es6"></script>
{% endcompress %}

Caveats

Most ES6 syntax seems to work pretty well, but requiring modules doesn't import correctly. Also, this approach adds some latency when compressing on the fly (i.e. COMPRESS_OFFLINE = False).

Run tests

poetry run pytest
