Issue #50 — Frontend: Notification TypeScript Type Definitions

[yusuftomilola]

Location: frontend/lib/types/notification.ts

Description

Before any notification hooks or UI components can be built, the TypeScript interfaces for the notifications feature need to be defined. These types are shared across the NotificationBell component, the notifications page, and any query hooks that interact with the notifications API.

Acceptance Criteria

• frontend/lib/types/notification.ts exports:
  • A NotificationType union type: "BOOKING_CREATED" | "BOOKING_CONFIRMED" | "BOOKING_CANCELLED" | "BOOKING_COMPLETED" | "PAYMENT_SUCCESS" | "PAYMENT_FAILED" | "INVOICE_READY"
  • A Notification interface with:
    • id: string
    • type: NotificationType
    • title: string
    • message: string
    • isRead: boolean
    • userId: string
    • createdAt: string
    • updatedAt: string
  • A NotificationsResponse interface with:
    • data: Notification[]
    • meta: { total: number; page: number; limit: number; totalPages: number; unreadCount: number }
• Only TypeScript interface and type declarations — no runtime code
• npx tsc --noEmit passes with no errors
