Doesn't Rails asset pipeline have an effect on the page size, like if Propshaft being used instead of Sprockets. From what I remember, Propshaft intentionally does not include minification or compression.
Itβs all Rails 8 + Turbo + Stimulus JS with Propshaft handling the asset bundling / pipeline.
All the Tailwind building and so on is done using common JS tools, which are mostly standard out of the box Rails 8 supplied scripts!
Sprockets used to do the SASS compilation and asset bundling, but the Rails standard now is to facilitate your own preferences around compilation of CSS/JS.
