When running the installer, I ran into issues where the installer expected Sprockets:

/var/home/reesericci/.rbenv/versions/3.3.2/lib/ruby/gems/3.3.0/gems/sprockets-rails-3.5.1/lib/sprockets/railtie.rb:106:in `block in <class:Railtie>': Expected to find a manifest file in `app/assets/config/manifest.js` (Sprockets::Railtie::ManifestNeededError)
But did not, please create this file and use it to link any assets that need
to be rendered by your app:

Example:
  //= link_tree ../images
  //= link_directory ../javascripts .js
  //= link_directory ../stylesheets .css
and restart your server

I was looking at what Administrate (thoughtbot/administrate#2397) did, and they linked this blog post which might be useful: https://avohq.io/blog/how-to-bundle-assets-in-a-rails-engine

[reesericci]

Alright, I made a fork with the sprockets stuff removed but I don't think it retains backwards compatibility

[smudge]

Thanks @reesericci! Yeah, as it stands this gem still depends on Sprockets, but I really like the newer strategy of compiling at publish time. Not sure if I'll have a chance to implement it, but I'm open to reviewing PRs that swap the gem onto that strategy.

Or if there's a way to make it work as-is with Propshaft, I could see making both Sprockets and Propshaft optional dependencies, and then changing the engine boilerplate depending on which is available at runtime. (Not sure how possible that is, because I haven't had a chance to try it myself.)

[reesericci]

I can try to figure it out sometime soon, but it looked pretty complicated to my new-ish eyes, so I ended up going with the easier strategy of stripping out all the sprockets stuff. Happy to take another look at it when I'm free in a bit though.

[smudge]

Feel free to open more GH issues if you encounter anything or have feature ideas while using the gem! We're always interested in feedback. 😀
