Remove spring and spring-watcher-listen (dev preloader)#89
Merged
Conversation
spring is optional developer tooling (an app preloader), not required at Rails 8.1 — modern Rails no longer ships it in the default Gemfile. It's a direct-only dependency here (nothing pulls it transitively), and in practice it's been a source of stale-state/hang gotchas (commands had to be run with DISABLE_SPRING=1). Dropping it simplifies the dev setup with no runtime impact. - Gemfile: remove gem "spring" + gem "spring-watcher-listen" (and the pin comment) - bin/rails, bin/rake: drop the spring loader preamble (standard binstubs) - delete bin/spring and config/spring.rb - both lockfiles updated Verified locally: bin/rails runner + bin/rake work without the preamble, test suite 16/52/0 (run via the binstubs), rubocop + reek clean.

What
Removes the
springapp preloader and itsspring-watcher-listenplugin.Why
springis optional developer tooling (a Rails application preloader) — not required at Rails 8.1, and no longer shipped in modern Rails' default Gemfile. Here it's a direct-only dependency (nothing pulls it transitively), and in practice it's been a source of stale-state / hang gotchas (one-shot commands had to be run withDISABLE_SPRING=1). Dropping it simplifies the dev setup with no runtime impact — spring never runs in production.Changes
