python-lightningcss

python-lightningcss offers PyO3 bindings to the lightningcss library. Presently only a subset of functionality is exposed, intended for integration into a Python-centric web application rather than a JavaScript-based workflow. If the latter is needed, consider using the official npm lightningcss module, parcel, or webpack instead.

Installation

python-lightningcss includes wheels which can be installed for most platforms using pip: pip install lightningcss.

Alternatively, python-lightningcss may be installed directly from source: pip install git+https://github.com/pydsigner/python-lightningcss. This will require that the Rust toolchain be installed.

Usage

import lightningcss

parser_flags = lightningcss.calc_parser_flags(nesting=True)
input_css = """
a {
    padding-left: 0;
    padding-right: 0;
    padding-top: 5px;
    padding-bottom: 5px;
}
"""
output_css = lightningcss.process_stylesheet(input_css, filename="abc.css", browsers_list=['defaults'])
