This application was made using Nodejs,Mongodb and express js. In this user can register their details and than can login.
The user can make appointement on any date and any time and if the slot is booked a message will be dispalyed.
I am fetchinng the time in hh:mm format but than converting it into hours to make hourly appointments.
The date and app is joined and serve as unique key and thus can track duplicate appointments.
