Install Stimulus LSP in RubyMine
There are two ways to get Stimulus Tooling Support in RubyMine.
Option 1
Install the community-driven project Stimulus LSP. This is the recommended way, since this is the plugin built by the community which also works for all editors.
Option 2
RubyMine supports Stimulus with the third-party Stimulus plugin. It is bundled and built-in with RubyMine 2024.2 and provides code completion, navigation, and rename refactoring for Stimulus.
