I’ve had some time to talk to others, and was offered a simplified explanation of what you are expected to choose:
The default (without node/yarn)
- Rails 7: Import Maps + Sprockets
- Rails 8: Import Maps + Propshaft
The “choose your own bundler” (with node/yarn)
- Rails 7: Bundling Gems + Sprockets
- Rails 8: Bundling Gems + Propshaft
I’ll also admit that the way I’ve written this guide makes it look more complicated, because I was trying to explain all the gems and give advice for three different types of users.
