Job-Info-Prod/CHANGELOG_SESSION.md

Session Changelog - January 1, 2026

Production Setup Session

What Was Done

1. Backend Setup

   • Copied working server.ts from Job-Info-Test
   • Added redis-cache.ts for Valkey/Redis caching
   • Fixed static file path to serve from frontend/public
   • Fast job loading: returns first 40 jobs instantly, then full list on poll

2. Frontend Setup

   • Copied working frontend from Job-Info-Test to frontend/public/
   • Simplified token validation at startup:
     • Check PocketBase session valid
     • Check Graph token in localStorage
     • If either missing → redirect to signin
   • Removed redundant token refresh loops
   • Added localStorage storage for Graph token in signin.html

3. Authentication Flow

   • PocketBase OAuth with Microsoft provider
   • Graph token stored in localStorage after signin
   • Both tokens checked once at page load
   • No repeated token validation during app usage

4. Systemd Service

   • Created /etc/systemd/system/job-info-prod.service
   • Runs on port 3005
   • Auto-restarts on failure

5. Git Repository

   • Initialized and pushed to: https://gitea.ccllc.pro/Cardoza_Construction/Job-Info-Prod.git
   • Branch: main

Key Files

File	Purpose

Endpoints

• GET / - Serve frontend
• GET /version - App version
• GET /api/health - Health check
• GET /api/jobs-all - All jobs (first 40 fast, then full)
• GET /api/jobs - Paginated jobs
• GET /api/job-files - SharePoint files via Graph API
• GET /api/job-file-content - File content/download
• GET /api/job-file-pdf - PDF proxy
• POST /log-change - Log changes

Configuration

• Port: 3005
• PocketBase: https://pocketbase.ccllc.pro
• Collection: pbc_1407612689
• Redis/Valkey: localhost:6379

Known Limitations

• Graph tokens expire after ~60 minutes (Microsoft limitation)
• No automatic Graph token refresh (would require direct OAuth flow)
• User must re-signin when Graph token expires

Next Steps

• Consider implementing direct Microsoft OAuth for refresh token support
• Add error boundaries for better UX on token expiry
• Performance monitoring
