1. POS Backend (evergreen_pos_be) Offer Date Range Query Fix (setting.service.js): Expanded offer query date boundaries (startDate set to 00:00:00.000 and endDate set to 23:59:59.999) to include offers expiring later on the target end date. Corrected date range overlap formula to { startDate: { $lte: filterEnd }, endDate: { $gte: filterStart } } so active offers display properly on the POS Admin Offers list page. 2. POS Admin Frontend (evergreen_pos_fe) Form.Item RangePicker Binding (offerForm.tsx): Removed wrapping <div> containers inside <Form.Item name="dateRange"> to enable direct state binding to Ant Design <RangePicker>, resolving the "Please select date range" validation error. Special Character Support for Offer Names (offerForm.tsx): Updated Offer Name validation regex pattern to /^[a-zA-Z0-9\s%:\-&$!,\.\/\(\)#]+$/ to allow percentage signs (20%), colons (:), hyphens (-), and common offer special characters. Atomic Date Range State Updates (offerDataFetching.ts, offerTable.tsx, offerindex.tsx): Refactored handleDateRangeChange for atomic React state updates when picking date ranges. 3. E-Commerce Web Storefront (evergreenpos_E-commerce_new) Header Real Offer Search Placeholder Priority (Header.tsx): Integrated active company offer API (/v1/nus-global/offer/all). Prioritized real offer placeholders (e.g. Offer: September Festive - 20% Off On Entire Category) to appear immediately as item #2 in the search bar animated typing sequence. Implemented single-timer state machine for typing animation to prevent stuck typing timers. Live Search Offer Matching & Query Normalization (Header.tsx): Added Offer: prefix stripping (cleanQuery) so searching for offer titles (e.g., Offer: September Festive...) accurately queries and retrieves matching category and product items without returning empty results. Calculated and attached offer discount properties (offer: 20, finalPrice) to search result cards so the red -20% OFF badge and original price strikethroughs (e.g. $54.00 $43.20) display in search dropdown cards. Resolved Maximum update depth exceeded React warning by stabilizing useEffect dependency arrays. Home OFFERS Section Integration (HomeMerchTabs.tsx): Updated merch-offer-pool query to combine both individual product-level discount items (e.g. Ear buds -90%) and global company offer items (e.g. 20% Off Category). Enhanced mapCard to calculate finalPrice and attach red -20% / -90% badges and price strikethroughs across all cards in the OFFERS tab.
