I'm developing react app and ım using nodejs for backend. I deployed project on heroku and ı used heroku-redis. Now ı want to develop some features. How can ı work on local ? When ı tried, ı couldn't watch changing and also when ı working on local, heroku server crashed. I didnt push anything but server crashed. I just want to change some codes and push again.
