Agile Web Development with Rails 7: No preloading in Rails 7 (Page 22)
This paragraph:
As you can see from the bin/ prefix, this is running the rails command from the bin directory. This command is a wrapper, or binstub, for the Rails executable. It serves two purposes: it ensures that you’re running with the correct version of every dependency, and it speeds up the startup times of Rails commands by preloading your application.
Seems to be assuming Spring, but Spring is no longer included in newly generated Rails 7 applications.

I don’t miss Spring ![]()
I’ve removed the beginning (“two purposes”) and end (“preloading”) of that sentence.
