  • noRebase became rebase - make sure to reverse the value;

source: clean-css

Regarding Issues

This is just a simple gulp plugin, which means it's nothing more than a thin wrapper around clean-css. If it looks like you are having CSS related issues, please contact clean-css. Only create a new issue if it looks like you're having a problem with the plugin itself.

Information

Packagegulp-minify-css
DescriptionMinify css with clean-css, including optional caching.
Node Version>= 0.10

Installion

npm install --save-dev gulp-minify-css

Usage

var gulp = require('gulp'),
		minifyCSS = require('gulp-minify-css');

gulp.task('minify-css', function() {
  gulp.src('./static/css/*.css')
    .pipe(minifyCSS({keepBreaks:true}))
    .pipe(gulp.dest('./dist/'))
});

Options

  • cache - check and return minified CSS from cache if it exists; minify and store in cache when it does not

This is a gulp-minify-css feature and not a clean-css feature.


  • advanced - set to false to disable advanced optimizations - selector & property merging, reduction, etc.
  • aggressiveMerging - set to false to disable aggressive merging of properties.
  • benchmark - turns on benchmarking mode measuring time spent on cleaning up (run npm run bench to see example)
  • compatibility - enables compatibility mode, see full README for more examples
  • debug - set to true to get minification statistics under stats property (see test/custom-test.js for examples)
  • inliner - a hash of options for @import inliner, see test/protocol-imports-test.js for examples
  • keepBreaks - whether to keep line breaks (default is false)
  • keepSpecialComments - * for keeping all (default), 1 for keeping first one only, 0 for removing all
  • processImport - whether to process @import rules
  • rebase - set to false to skip URL rebasing
  • relativeTo - path to resolve relative @import rules and URLs
  • root - path to resolve absolute @import rules and rebase relative URLs
  • roundingPrecision - rounding precision; defaults to 2; -1 disables rounding
  • shorthandCompacting - set to false to skip shorthand compacting (default is true unless sourceMap is set when it's false)

Source: clean-css

Source maps

Source maps can be generated by using gulp-sourcemaps:

var gulp = require('gulp');
var minifyCSS = require('gulp-minify-css');
var sourcemaps = require('gulp-sourcemaps');

gulp.task('minify-css', function() {
  gulp.src('./src/*.css')
    .pipe(sourcemaps.init())
    .pipe(minifyCSS())
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('dist'));
});
Caveats

When minifying (and import inlining) files with existing source map, be aware clean-css doesn't yet support source maps with inline source (sourcesContent property).. See #397. As such ensure that incoming source maps have properly set sourceRoot and soureces values to map back to the original source files.
