Hi guys,
I just finished another backend project of FCC - Manage a Book Trading Club App. Hope to get some feedback from you guys to improve the app.
Thanks!

looks nice, I also just started on this project, one problem I see with yours is that on signup it redirects to the local host (although it actually signs you up and logs you in), my guess would be that you probably forgot to redirect to your heroku site on sign up after deploying it.
You’re right. I forgot to do that when I deployed the app on heroku. I will fix it now. Thank you 
Problem is fixed!
