reservation-manager

GraphQL microservice for Reservation booking between a Provider and a Client.

Functionality

• Seeds a bit of test data into the "Database" using EF InMemory DB
• Supports GraphQL queries for
  • Providers
  • Appointments
• Supports GraphQL mutations for
  • Creating timeslots for a provider given a date range
  • Reserving an appointment
  • Confirming a reserved appointment
  • Appointment expiration.

What we're missing

• Unit tests. Ideally would like to interface with the DbContext from the service layer, as this does make mocking a bit more tricky. In the future, I'd break it out.
• Input validation - There is a bit of validation done, but to be robust, would need much more.
• Auth. The API is wide open. Anyone can reserve and create appointments for anyone.
• Flexibility - Appointment slots are always 15 minutes. There is a big lack of filtering / paging that you'd want.
• CI/CD - No docker. No Github actions. No k8s manifest. This is pretty bare bones.
