This repo was forked from Ben Briggs' css-minifiers. It has been tweaked for testing to determine what minifier to use in Red Perfume.
| Engine | Stars | Runs | Size | Time (ms) | Notes |
|---|---|---|---|---|---|
| clean-css | 3,808 | ✅ | 252 | 8.52 | second largest in file size, slowest to run |
| crass | 98 | ✅ | 186 | 7.95 | Second smallest file size out of all tested, second slowest |
| css-condense | 209 | ✅ | 244 | 6.25 | |
| css-smasher | 6 | ❌ | pretty rudimentary engine, one release from 7 years ago, not worth effort to get it to run | ||
| cssnano | 3,905 | ❌ | 194 | Verions 3 worked, but 5 now requires PostCSS to import a jungle with a gorrilla to get a banana | |
| csso | 3,334 | ✅ | 209 | 5.33 | |
| cssshrink | 1,073 | ❌ | It uses "latest" dependency versions that are incompatible with these benchmarks | ||
| csswring | 163 | ✅ | 214 | 4.40 | |
| lightning | 5,631 | ✅ | 153 | 3.82 | Though written in Rust, no significant perfomance difference. Smallest output, but does so by discarding needed CSS, also retains CSS that is not needed. |
| more-css | 67 | ❌ | This is more like Less/Stylus, AKA a worse version of Sass, with no releases and no updates in 6 years | ||
| ncss | 7 | ✅ | 252 | 3.68 | |
| sass | 2,534 | ✅ | 241 | 5.57 | Though Sass does a lot more, it can still just be used for CSS minification and is 3rd slowest |
| sqwish | 201 | ✅ | 211 | 1.66 | Second best speed, 5th best compression |
| ycssmin | 52 | ✅ | 253 | 1.47 | largest file size out of all tested, also fastest to run |
