Important Info

The scope of this app is very limited.

• It allows you to create users, with no access at all.
• An employee user has "Employee" role, whereas, an Admin user has "admin" role. All users create via React app are normal user with no access, except logging in. The roles must be added to the db manually.

   {
     username: String, 
     roles: ["admin"]
   }

• An admin can upload upto 10 employee files at times.
  • An employee file missing the format defined above will be discarded.
  • Only pdf files are accpeted.
  • A user with EmployeeId as Username & Password is created, as soon as his file is uploaded.
  • The user created by admin has the "employee" role by default

• Employee files are stored in MongoDb's GridFs buckets.
