From 27303c6be09b8fc24c13454deae234e480cbf995 Mon Sep 17 00:00:00 2001 From: Michał Gołębiowski-Owczarek Date: Wed, 31 May 2023 18:59:35 +0200 Subject: Build: Switch the minifier from UglifyJS to Terser UglifyJS is ES5-only, while Terser supports newer ECMAScript versions. jQuery is authored in ES5 but jQuery 4.x will also have an ESM build that cannot be minified using UglifyJS directly. We could strip the `export` statement, minify via UglifyJS and re-add one but that increases complexity & may not fully play nice with source maps. On the other hand, switching to Terser increases the minfied size by just 324 bytes and the minified gzipped one by just 70 bytes. Such differences largely disappear among bigger size gains from the `3.x-stable` line - around 2.7 KB minified gzipped as of now.
