Guide on running CSSO command line CSS minifier in node.js

I have been attempting to utilize the CSSO command-line tool with node.js.

Unfortunately, I am struggling to figure out how to simply call the csso command.

You can find CSSO's documentation on this page: https://github.com/css/csso#33-from-the-command-line

I followed the steps on the documentation page to download CSSO using NPM. It is already installed as I can use

require("csso").justDoIt(".....")

, but that method does not work for me. I need to execute it in a command line because I require this CSS minifier during some Visual Studio build process.

Please note that using another compressor is not a solution. I have tried YUI, AjaxMin, and others with command-line interfaces, but they do not merge duplicated classes, identifiers, and selectors into a single one.

Thank you in advance!!!

If you need to make adjustments to the csso file located in the bin folder, you can simply modify the /csso/lib/csso.js file. You could potentially work around it by using a command like:

node /path/to/csso/lib/csso.js -i -o

This code hasn't been tested, so you may need to tweak some variables to get it working properly. However, this should give you a starting point for finding a solution!

Utilize node's child process

var spawn = require('child_process').spawn,
csso  = spawn('csso/bin/csso', ['test.css']);

csso.stdout.on('data', function (data) {
  console.log('stdout: ' + data);
});
