While installing tailwind I kept getting “Webpacker can’t find application in…” which sent me down a few rabbit holes. Figured id share the PR to add tailwind to save future people searching.
After typing jets webpacker:install then copy/paste the PR contents.
Webpacker woes. Tell me about it 
It’s a rabbithole everytime webpacker breaks due to upstream javascript libraries. Was able to fix webpacker in the jets v4 (ruby 3.2 support release) and also in the jets v5 branch, but it’s not easy. Will do what Rails is doing here and eventually deprecate it. It can be a separate project or plugin if folks are really interested in it and are willing to maintain it.
