From 8309f584ece4e7d66aaebe9fc05435a0753fcfa4 Mon Sep 17 00:00:00 2001 From: acdlite Date: Fri, 19 Apr 2024 18:28:37 +0000 Subject: [PATCH] Run Closure on non-minified prod builds, too (#28827) In #26446 we started publishing non-minified versions of our production build artifacts, along with source maps, for easier debugging of React when running in production mode. The way it's currently set up is that these builds are generated *before* Closure compiler has run. Which means it's missing many of the optimizations that are in the final build, like dead code elimination. This PR changes the build process to run Closure on the non-minified production builds, too, by moving the sourcemap generation to later in the pipeline. The non-minified builds will still preserve the original symbol names, and we'll use Prettier to add back whitespace. This is the exact same approach we've been using for years to generate production builds for Meta. The idea is that the only difference between the minified and non- minified builds is whitespace and symbol mangling. The semantic structure of the program should be identical. To implement this, I disabled symbol mangling when running Closure compiler. Then, in a later step, the symbols are mangled by Terser. This is when the source maps are generated.
