From 811fc9d49c7f2ef128780d9b1a8dac31831f1f7b Mon Sep 17 00:00:00 2001 From: silverwind Date: Fri, 7 Jul 2023 20:28:48 +0200 Subject: [PATCH] Minify CSS with Lightning CSS (#25754) Replace esbuild's rudimentary CSS minifier with [Lightning CSS](https://github.com/parcel-bundler/lightningcss), which results in around 4% smaller CSS bundle size, index.css goes from 608K to 584K. The module is quite new but has active use in the Parcel bundler, and as of yesterday is also under experimental support in Vite, so I trust it that bugs will be sorted out quickly. Before: `assets by path css/*.css 959 KiB` After: `assets by path css/*.css 933 KiB` I did give this a cursory test and everything seems to be in order. --- package-lock.json | 210
