clean-css with the default Promise interface and some improvements
``javascript
const CleanCssPromise = require('clean-css-promise');
(async () => {
const {styles} = await new CleanCssPromise().minify(
p {
color: #ff0000;
}
b {
/ nothing /
}); //=> 'p{color:red}'`
})();
`
npm install clean-css-promise
`javascript`
const CleanCssPromise = require('clean-css-promise');
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*.
`javascript
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. */``
