Disable babel-loader's cacheCompression #7633
Conversation
`cacheCompression` is an enabled-by-default flag in babel-loader, which gzips the babel-loader cache. Most projects do not actually benefit from cache compression, especially in production where builds often happen in a CI environment where memory is precious and disk space is not. Furthermore, having it disabled in dev and enabled in prod means caching won't be shared between dev and prod. Finally, the disk space savings are not that great. Most React projects will have a lot of small files (one file per component). babel-loader caches each file as a unit, so the compression overhead increases when the project is mainly lots of small files. For these reasons, we're disabling cache compression. Closes #6846

Thank you for signing our Contributor License Agreement. We can now accept your code for this (and any) Facebook open source project. Thanks! |
Dunno why the builds are failing but seems unrelated to this PR:

Seems like a reasonable change. Let's try it out. Hopefully we'll see some perf improvements for our users! |
Context: #6846 - I received no feedback on it, so I figure a PR is more actionable.
Changes have been tested running on a live website since I filed the issue. Build times and their memory consumption have both decreased with no further issue arising.
