Implemented all 5 critical efficiency improvements to optimize
performance, reduce resource usage, and improve scalability.
## 1. Database Indexes
- Added indexes on sermon_notes foreign keys (user_id, sermon_id)
- Added composite index on sermons (archived, date DESC)
- Added indexes on frequently queried columns across all tables
- Impact: Faster queries as data grows, better JOIN performance
## 2. Eliminated N+1 Query Pattern
- Reduced 2 API calls to 1 on home page load
- Changed from separate active/archived fetches to single call
- Filter archived sermons client-side using computed properties
- Impact: 50% reduction in HTTP requests per page load
## 3. Scheduled Database Cleanup
- Extended existing plugin to clean expired sessions hourly
- Added cleanup for expired rate limits every hour
- Added cleanup for expired password reset codes every hour
- Sermon cleanup continues to run daily based on retention policy
- Impact: Prevents database table growth, better performance
## 4. Multi-stage Docker Build
- Implemented 3-stage build: deps -> builder -> runtime
- Separated build-time and runtime dependencies
- Added non-root user (nuxt:nodejs) for security
- Integrated dumb-init for proper signal handling
- Added health check endpoint at /api/health
- Impact: Smaller image size, faster deployments, better security
## 5. HTTP Caching
- Static assets: 1 year cache (immutable)
- Logos/images: 1 year cache (immutable)
- API routes: No cache (always fresh)
- HTML pages: 10 minute cache with revalidation
- Impact: Reduced bandwidth, faster page loads, less server load
All optimizations follow best practices and maintain backward
compatibility with existing functionality.

When an admin manually unlocks an account, both the account-level
lockout and all IP-based rate limits for the login endpoint are now
cleared. This ensures legitimate users can immediately attempt to
login after being unlocked, without being blocked by stale rate
limit cache entries.
Changes:
- Added clearAllRateLimitsForEndpoint() function to database utils
- Modified unlock endpoint to clear login rate limits after unlocking
- Updated success message to reflect rate limit clearing
- Enhanced logging to track rate limit clearing operations
Fixes issue where users would see "Too many login attempts" message
even with correct credentials after admin unlock, due to persistent
IP rate limit cache from previous failed attempts.

Fixed inconsistency between IP-based rate limiting and per-account lockout.
Previously, users would hit the IP rate limit at 5 attempts (15 min lockout)
but the account wouldn't be marked as locked until 10 attempts (30 min).
This caused confusion in the admin UI where locked accounts wouldn't show
the unlock button until 10 attempts were reached.
Changes:
- Reduced account lockout threshold from 10 to 5 failed attempts
- Reduced account lockout duration from 30 to 15 minutes
- Updated error message to reflect 15 minute lockout period
- Added detailed logging when account gets locked
- Updated README documentation to reflect correct limits
Both protection layers now work in harmony:
- IP-based rate limiting: 5 attempts = 15 min lockout
- Per-account lockout: 5 attempts = 15 min lock
This ensures the admin UI accurately shows account lock status and provides
the unlock option as soon as users hit the lockout threshold.

Fixed an issue where SMTP configuration would fall back to defaults despite
environment variables being set in docker-compose.yml. The email utility now
properly accesses runtime configuration by accepting the H3 event context.
Changes:
- Created getEmailConfig() helper with dual-strategy config access
- Pass event context from API handlers to email functions
- Added fallback to direct process.env access for reliability
- Added debug logging to diagnose configuration issues in production
This ensures Office365 and other SMTP providers work correctly when configured
via environment variables.

Implemented a configurable retention policy system for sermons with automatic cleanup:
- Added settings table to store retention policy configuration
- Created API endpoints for getting/setting retention policy
- Added Database Settings section to admin page with retention options (forever, 1-10 years)
- Implemented manual cleanup endpoint for on-demand deletion
- Added automated daily cleanup task via Nitro plugin
- Sermons are deleted based on their date field according to the retention policy
