jsmin

JavaScript minifier.

Usage

from jsmin import jsmin
with open('myfile.js') as js_file:
    minified = jsmin(js_file.read())

You can run it as a commandline tool also:

python -m jsmin myfile.js

NB: jsmin makes no attempt to be compatible with ECMAScript 6 / ES.next / Harmony. The current maintainer does not intend to add ES6-compatibility. If you would like to take over maintenance and update jsmin for ES6, please contact Tikitu de Jager. Pull requests are also welcome, of course, but my time to review them is somewhat limited these days.

If you're using jsmin on ES6 code, though, you might find the quote_chars parameter useful:

from jsmin import jsmin
with open('myfile.js') as js_file:
    minified = jsmin(js_file.read(), quote_chars="'\"`")

Where to get it

install the package from pypi
get the latest release from latest-release on github
get the development version from master on github

Python 2 support removed

Python 2 support was removed in version 3.0.0. If you need to support Python 2, please use version 2.2.2 with setuptools<58.

Contributing

Issues and Pull requests will be gratefully received on Github. The project used to be hosted on bitbucket and old issues can still be found there.

If possible, please make separate pull requests for tests and for code: tests will be added to the latest-release branch while code will go to master.

Unless you request otherwise, your Github identity will be added to the contributor's list below; if you prefer a different name feel free to add it in your pull request instead. (If you prefer not to be mentioned you'll have to let the maintainer know somehow.)
