gulp-clean-css

gulp plugin to minify CSS, using 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.

1const gulp = require('gulp');
2const cleanCSS = require('gulp-clean-css');
3
4gulp.task('minify-css', () => {
5  return gulp.src('styles/*.css')
6    .pipe(cleanCSS({compatibility: 'ie8'}))
7    .pipe(gulp.dest('dist'));
8});

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.

1const gulp = require('gulp');
2const cleanCSS = require('gulp-clean-css');
3
4gulp.task('minify-css', () => {
5  return gulp.src('styles/*.css')
6    .pipe(cleanCSS({debug: true}, (details) => {
7      console.log(`${details.name}: ${details.stats.originalSize}`);
8      console.log(`${details.name}: ${details.stats.minifiedSize}`);
9    }))
10  .pipe(gulp.dest('dist'));
11});

Source Maps can be generated by using gulp-sourcemaps.

1
2const gulp = require('gulp');
3const cleanCSS = require('gulp-clean-css');
4const sourcemaps = require('gulp-sourcemaps');
5
6gulp.task('minify-css',() => {
7  return gulp.src('./src/*.css')
8    .pipe(sourcemaps.init())
