Visualizing Reservation Workflows with Mermaid in Hugo

Mermaid diagrams offer a fantastic way to visualize workflows, decisions, and parallel processes in a clear, easy-to-understand format. Below, you’ll find a Mermaid activity diagram that highlights the workflow of creating a reservation in your system.

This workflow includes decision points (e.g., checking resource availability) and parallel processes (e.g., notifying external systems like payment gateways or customer notification services). You can copy and paste the code into a Mermaid-enabled editor to visualize the diagram.

Mermaid Diagram Code:

stateDiagram-v2 state "Start" as Start state "Submit Reservation Request" as SubmitRequest state "Check Resource Availability" as CheckAvailability state "Resource Available?" as ResourceAvailable state "Reject Reservation" as RejectReservation state "Process Reservation" as ProcessReservation state "Publish ReservationCreated Event" as PublishEvent state "Notify Payment Gateway" as NotifyPayment state "Notify Customer" as NotifyCustomer state "End" as End Start --> SubmitRequest SubmitRequest --> CheckAvailability CheckAvailability --> ResourceAvailable ResourceAvailable --> RejectReservation: No RejectReservation --> End ResourceAvailable --> ProcessReservation: Yes ProcessReservation --> PublishEvent PublishEvent --> NotifyPayment PublishEvent --> NotifyCustomer NotifyPayment --> End NotifyCustomer --> End

Key Workflow Points:

  1. Submit Reservation Request: Customers initiate the process by submitting a request via the frontend.

  2. Check Resource Availability: The system checks if the requested resource is available at the specified time.

  3. Decision Point (Resource Available):

    • If unavailable, the reservation is rejected, and the process ends.
    • If available, the reservation moves to the processing stage.

  4. Parallel Processes:

    • Publish a ReservationCreated event to notify external systems.
    • Notify Payment Gateway: Process payment for the reservation.
    • Notify Customer: Send reservation confirmation via email, SMS, or other channels.

  5. End: The workflow concludes once payment processing and customer notification are complete.
