gulp-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.
Install
npm install gulp-clean-css --save-dev
API
cleanCSS([options], [callback])
options
See the CleanCSS options.
var gulp = require('gulp');
var cleanCSS = require('gulp-clean-css');
gulp.task('minify-css', function() {
return gulp.src('styles/*.css')
.pipe(cleanCSS({compatibility: 'ie8'}))
.pipe(gulp.dest('dist'));
});callback
Useful for returning details from the underlying minify() call. An example use case could include logging stats of the minified file. In addition to the default object, gulp-clean-css provides the file name and path for further analysis.
var gulp = require('gulp');
var cleanCSS = require('gulp-clean-css');
gulp.task('minify-css', function() {
return gulp.src('styles/*.css')
.pipe(cleanCSS({debug: true}, function(details) {
console.log(details.name + ': ' + details.stats.originalSize);
console.log(details.name + ': ' + details.stats.minifiedSize);
}))
.pipe(gulp.dest('dist'));
});Source Maps can be generated by using gulp-sourcemaps.
var gulp = require('gulp');
var cleanCSS = require('gulp-clean-css');
var sourcemaps = require('gulp-sourcemaps');
gulp.task('minify-css', function() {
return gulp.src('./src/*.css')
.pipe(sourcemaps.init())
.pipe(cleanCSS())
.pipe(sourcemaps.write())
.pipe(gulp.dest('dist'));
});
});
