minifyjs

Python bindings for MinifyJS, a native JavaScript minifier and optimizer. No Node.js required.

Install

pip install minifyjs

Use

from minifyjs import minify

result = minify("function add(a, b) { return a + b; }")
print(result.code)
# function add(a,b){return a+b;}

Full optimization and identifier mangling:

from minifyjs import optimize

result = optimize("const x = 1 + 2 + 3;")
print(result.code)   # const x=6;

Explicit control:

from minifyjs import minify, Options

result = minify(source, Options(
    compress=True,
    mangle=True,
    target="es2015",
    sourcemap="inline",
))

Bundling:

from minifyjs import bundle

result = bundle("src/main.js", outdir="dist", format="esm")

Adapter for frameworks

MinifyJS ships a generic adapter (minifyjs.adapter) that any framework or build system can subclass. See docs/integrations/generic-python.md for how to write an adapter for Django, Flask, FastAPI, or a custom build pipeline.

Command line

The native minifyjs binary is installed alongside the Python package:

minifyjs app.js -o app.min.js
minifyjs app.js --compress --mangle
cat app.js | minifyjs

Or, without the binary on PATH:

python -m minifyjs --version
