So @burmudar and I woke up this morning and we decided that the server image needed a 🧹.
Half the build time is spent building the client bundle. So we cached the client bundle ♂️.
It's done in a very crude way, but it works unless proven otherwise. It checksums the /ui, /client folders and ./package.json in order to build a cache key. It caches the entire /ui folder.
It effectively shaves off about 7~9 minutes on the server image build.
