I am using ReactJs with rails . i am using react-rails gem. Everything is working fine on local machine, but when deployed it on my ubuntu server, it produces undefined method react_component error. I try to run app locally on production mode everything works fine . On my production server i use Nginx with Unicorn.
After looking into my capistrano settings, i figure out my unicorn server is not restart after deployment. So i kill my unicorn process and deploy again and everything is working fine now.
