Job-Info/CHANGELOG_SESSION.md

Session Changelog - December 11-12, 2025

Summary of Changes

1. Fixed Decimal Number Sorting

• Issue: Job numbers with decimals (e.g., 3887.2) were sorting incorrectly, appearing before higher whole numbers (e.g., 4735)
• Solution: Replaced parseInt with parseFloat and used regex /[0-9]+\.?[0-9]*/ to correctly extract and compare decimal job numbers
• File: Frontend/index.html
• Function: jobNumberValue()

2. Removed Premature Initial Render

• Issue: Cards were flashing with incorrect order during initial page load, then updating after full load completed
• Solution: Removed the initialRendered flag and early applyFiltersAndRender() call during the fetch loop
• Result: Cards no longer render until data is properly sorted and ready

3. Implemented Server-Side Sorting

• Change: Added &sort=-Job_Number parameter to PocketBase API query
• Benefit: Data arrives pre-sorted in descending order, eliminating client-side sort overhead
• File: Frontend/index.html
• Function: fetchAllJobs()

4. Implemented Progressive Loading (2-Phase)

• Phase 1: First 40 cards display immediately after first batch loads (~50 records from perPage=50)
• Phase 2: Remaining cards load in background and full list renders when complete
• Benefit: Users see meaningful content within 1-2 seconds instead of waiting for full dataset
• File: Frontend/index.html
• Functions:
  • fetchAllJobs() - triggers render at 40 cards
  • renderInitialBatch() - renders first 40 cards immediately
  • applyFiltersAndRender() - renders complete sorted list after all data loaded

5. Expanded Cards Viewing Area

• Change: Converted layout to flexbox with height:100vh on body
• Result: Cards area now extends to bottom of screen, leaving only version footer visible
• Improvements:
  • Better use of screen real estate
  • More cards visible without scrolling
  • Cleaner full-screen experience
• Files Modified: Frontend/index.html
• CSS Changes:
  • body: Added height:100vh, display:flex, flex-direction:column, overflow:hidden
  • .wrap: Changed to display:flex, flex-direction:column, flex:1, overflow:hidden, removed margin
  • #results: Changed max-height:56vh to flex:1 for dynamic expansion

Performance Improvements

• Perceived Load Time: ~1-2 seconds for first 40 cards (was waiting for full load)
• Search/Filter Responsiveness: Now uses server-side sort, reducing client-side computation
• Memory: Progressive loading means full dataset isn't necessarily all rendered at once

Files Modified

• Frontend/index.html (primary changes)
• No backend or configuration changes required

Testing Notes

• Decimal job numbers (e.g., 3887.2, 4735) now sort correctly in descending order
• Initial page load shows first 40 cards immediately
• Remaining pages load in background with progress bar indication
• Full list renders with all filters/search applied once complete
