I don't know how to write code without guard. I want the JS specs to run when js files or specs are saved.
The JS specs are currently run via evergreen, which is no longer maintained. I would love to migrate the specs to something that is maintained and better integrates with the Rails asset pipeline.
I'm using https://github.com/netzpirat/guard-jasmine in a project.
I've also used guard-jasmine with a lot of success.
I've had success with konacha as well https://github.com/alexgb/guard-konacha
