Walkthrough

A new client-side React page for viewing weekly staff schedules is introduced. It authenticates users via a local auth hook, fetches shifts and leave request data from Supabase for the current week plus buffer weeks, and renders a 7-day grid with shifts, leaves, weekly offs, and week navigation controls.

Changes

Cohort / File(s)

Summary

Schedule Page Component app/staff/schedule/page.tsx

New client page component implementing a weekly schedule view. Includes Supabase client initialization, user authentication via useAuth, data fetching for shifts and leave requests within a rolling date window, state management for currentDate/shifts/leaves/loading, and a responsive 7-day grid UI with day headers, shift/leave display, and navigation controls (prev/next week, today button). Incorporates error handling with special-case tolerance for a missing table error (42P01) during development.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~12 minutes

• Supabase query logic and error handling strategy, particularly the intentional bypass of 42P01 errors
• Date window calculation logic and boundary conditions (previous/next week buffer)
• State dependency chains in useEffect hooks to ensure proper data fetching on date changes
• Leave request filtering logic for rejected statuses and date range overlaps

Poem

🐰 A schedule page takes shape with grace,
Showing shifts in time and space,
Supabase calls with auth so fine,
Seven days in perfect line,
Hippity-hop, the view's divine! ✨
