clean-css-promise

npm version Github Actions codecov

clean-css with the default Promise interface and some improvements

const CleanCssPromise = require('clean-css-promise');
 
(async () => {
  const {styles} = await new CleanCssPromise().minify(`
p {
  color: #ff0000;
}
 
b {
  /* nothing */
}
`); //=> 'p{color:red}'
})();

Installation

Use npm.

npm install clean-css-promise

API

const CleanCssPromise = require('clean-css-promise');

class CleanCssPromise([options])

options: Object (clean-css constructor options)

Almost the same the original clean-css, except for:

  • returnPromise option is enabled by default, and cannot be disabled.
  • onRejected function receives an Error instead of an Array.
  • All problems that clean-css considers as warnings, for example broken CSS syntax, are regarded as errors.
const CleanCssPromise = require('clean-css-promise');
 
new CleanCssPromise({})
.minify('@import url(/foo);}')
.catch(err => {
  err.message;
  /*=> `2 errors found while optimizing CSS with clean-css:
  1. Ignoring local @import of "/foo" as resource is missing.
  2. Invalid character(s) '?' at 1:18. Ignoring.
 
clean-css dangerously ignores these errors but clean-css-promise doesn't, because it's much more reasonable to update the CSS to fix all problems than to pretend that you didn't see the errors.` */
