source: clean-css
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.
Package | gulp-minify-css |
Description | Minify css with clean-css, including optional caching. |
Node Version | >= 0.10 |
npm install --save-dev gulp-minify-css
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/'))
});
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.

Source: clean-css
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'));
});
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.
