Question 1

How do I use gulp-clean-css with source maps?

Accepted Answer

Integrate it with gulp-sourcemaps by initializing sourcemaps before the plugin and writing them after, as shown in the README. This allows debugging minified CSS in browser dev tools with original source references.

Question 2

gulp-clean-css vs gulp-cssnano: which should I use?

gulp-clean-css uses clean-css, known for good compression and IE compatibility, while gulp-cssnano uses cssnano, which may offer more modern CSS optimizations. Choose based on your project's specific needs and the underlying library features.

Question 3

How to log minification stats with gulp-clean-css?

Accepted Answer

Use the callback parameter in the plugin to access details like originalSize and minifiedSize from the stats object, then log them or use for analysis, as demonstrated in the API section with debug mode.

Question 4

Can gulp-clean-css handle modern CSS like custom properties?

Accepted Answer

Since it relies on clean-css, it depends on clean-css's support for CSS features. Clean-css generally handles modern CSS, but for specific issues, check the clean-css documentation or report problems there, as noted in the README.

Question 5

How to set up gulp-clean-css in a new Gulp project?
