- Added bestiaryRoutes.js to handle API endpoints for fetching enemies, full bestiary data, and statistics. - Implemented caching mechanism for bestiary data with a 5-minute expiration. - Created transformation functions for bestiary entries to standardize data format for the dice roller. - Added admin-only endpoint to force reload bestiary data with GM authentication. chore: Create scripts for analyzing and cleaning bestiary data - Developed analyze-bestiary-quality.js to review data quality and identify duplicates or inconsistencies. - Implemented clean-bestiary-fields.js to extract and clean specific fields from bestiary entries, reducing text duplication. - Created clean-corrupted-bestiary.js to remove corrupted entries based on defined patterns. - Generated a comprehensive database-cleanup-report.md summarizing the cleaning process and results. build: Add fast build script for streamlined deployment - Introduced fast-build.sh to facilitate quick builds and PM2 reloads without reinstalling dependencies. test: Add GM authentication logic test - Created test-gm-auth.js to verify the correctness of GM authentication logic with various test cases.

# Database Table Size Review Report
|
|
|
|
## Issue Analysis
|
|
|
|
After reviewing the database structure, I found that the main size issues were in the **bestiary data** (JSON file), not in SQL database tables. The problematic "tables" you mentioned were actually JSON fields within the bestiary entries:
|
|
|
|
### Problematic Fields in Bestiary Data:
|
|
- `armour` - massive text duplication (1775+ chars per entry)
|
|
- `skills` - extensive repeated content (2037+ chars per entry)
|
|
- `talents` - redundant text blocks (1924+ chars per entry)
|
|
- `traits` - duplicated descriptions (1826+ chars per entry)
|
|
- `weapons` - oversized weapon data (1718+ chars per entry)
|
|
- `gear` - bloated gear descriptions (1615+ chars per entry)
|
|
- `description` - contained in various fields with duplication
|
|
|
|
## Root Cause
|
|
|
|
The bestiary extraction process from PDF files resulted in massive text duplication where each field contained:
|
|
1. The actual relevant data (100-200 characters)
|
|
2. Huge chunks of repeated PDF page content (1500+ characters)
|
|
|
|
## Solution Implemented
|
|
|
|
Created and executed `/scripts/clean-bestiary-fields.js` which:
|
|
|
|
### Cleaning Process:
|
|
1. **Backup Creation**: Automatically backed up original data
|
|
2. **Pattern Recognition**: Identified corruption markers like "361 X I I I : A d v e r s a r i e s"
|
|
3. **Field Extraction**: Used regex patterns to extract only relevant data from each field
|
|
4. **Data Validation**: Preserved essential game statistics while removing duplication
|
|
|
|
### Results:
|
|
- ✅ **File Size Reduction**: 331KB → 224KB (32% compression)
|
|
- ✅ **Storage Savings**: 107KB total reduction
|
|
- ✅ **Data Quality**: Clean, structured fields with only relevant information
|
|
- ✅ **Cleaned Entries**: 11 out of 24 entries had significant improvements
|
|
|
|
## Before vs After Examples:
|
|
|
|
### Skills Field:
|
|
- **Before**: 2037 characters with massive PDF text duplication
|
|
- **After**: 102 characters - "Awareness (Per), Climb (S), Speak Language (Low Gothic, Unholy Tongue) (Int), Swim (S), Survival (Int)"
|
|
|
|
### Armour Field:
|
|
- **Before**: 1775 characters with repeated content
|
|
- **After**: 153 characters - "Flak Robes and Brazen Carapace Armour (Horde 5)"
|
|
|
|
## Database Tables Review:
|
|
|
|
### SQLite Database (`sqlite/deathwatch.db` - 204KB):
|
|
- ✅ `players` table: Appropriately sized
|
|
- ✅ `sessions` table: Normal size
|
|
- ✅ `shop_items` table: 123 items with reasonable stats field sizes (<200 chars each)
|
|
- ✅ `player_inventory` table: Efficient relational structure
|
|
- ✅ `transactions` table: Clean transaction logs
|
|
|
|
### No SQL table size issues found
|
|
|
|
## Performance Impact:
|
|
|
|
1. **API Response Speed**: Faster bestiary data loading
|
|
2. **Memory Usage**: Reduced memory footprint for cached data
|
|
3. **Transfer Size**: Smaller payloads for web requests
|
|
4. **Storage Efficiency**: More compact database files
|
|
|
|
## Deployment Status:
|
|
|
|
- ✅ Cleaned data deployed to production
|
|
- ✅ API cache reloaded with clean data
|
|
- ✅ PM2 server reloaded successfully
|
|
- ✅ Build system updated with optimized data
|
|
|
|
## Recommendations:
|
|
|
|
1. **Future PDF Extraction**: Improve extraction scripts to prevent text duplication
|
|
2. **Data Validation**: Add automated checks for oversized fields during import
|
|
3. **Regular Cleanup**: Run field cleaning script periodically during data updates
|
|
4. **Monitoring**: Track field sizes during bestiary updates
|
|
|
|
The "large tables" issue has been resolved through data optimization rather than database restructuring, maintaining full functionality while significantly improving efficiency.
