🔍 Key Features

1. Schema Validation

Implementation: validation.js with Ajv library

  • Validates all JSON files against schemas before processing
  • Catches schema violations immediately
  • Provides detailed error messages with field paths
  • Supports lenient validation (warnings vs errors)

Example Output:

✅ Schema valid: buildings.json
❌ Schema validation failed: planets.json
  /mapData/51/mainPlanet: must be string

2. Change Detection

Implementation: change-detection.js with crypto module

  • Computes SHA-256 hash of data
  • Extracts structural information (fields, types, keys)
  • Compares current vs previous structure
  • Detects:
    • ✨ New files
    • 📝 Data changes
    • ⚠️ Breaking changes (removed fields, type changes)
    • ➕ Additions (new fields)

Example Output:

✨ New file: ship-formulas.json
⚠️ Breaking changes in buildings.json
   - Removed field: oldField
   - Type changed: tier (string → integer)

3. Multi-Part File Processing

Implementation: New processShipComponents() function

  • Reads manifest file (ship-components.json)
  • Loads all parts (part1, part2)
  • Merges components from multiple 7+ MB files
  • Generates optimized outputs
  • Tracks version and timestamps

Result: 3,756 components merged successfully

4. Validation Reporting

Implementation: reporting.js module

  • Generates JSON report after each refresh
  • Tracks success/failure for each task
  • Logs breaking changes and alerts
  • Provides detailed diff information

Output: Data/REFRESH-REPORT.json

{
  "timestamp": "2025-10-14T03:19:53.840Z",
  "summary": {
    "total": 10,
    "successful": 10,
    "failed": 0,
    "withChanges": 3,
    "withBreakingChanges": 0,
    "newFiles": 1
  },
  "alerts": [...],
  "details": [...]
}

🚀 Usage

Running RefreshData

# From project root
npm run refresh

# Or directly
cd RefreshData
node refresh-data.js

Expected Output

===========================================
   Enhanced Data Refresh Process v2.0
===========================================

✅ Loaded 9 schema(s)

📋 Processing: recipes.json
✅ Schema valid: recipes.json
Processed recipes.json -> recipes-data.js (4749.1 KB source)

📋 Processing: buildings.json
✅ Schema valid: buildings.json
Processed buildings.json -> buildings-data.js (2436.2 KB source)

... [8 more tasks] ...

=== Validation Report ===
Total tasks: 10
✅ Successful: 10
❌ Failed: 0
📝 With changes: 0
⚠️ Breaking changes: 0
✨ New files: 0

✅ All data files refreshed successfully.

Error Handling

The script exits with code 1 if:

  • Any task fails
  • Schema validation fails
  • Breaking changes detected

This makes it safe for CI/CD pipelines.

📝 Schema Examples

buildings.schema.json

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "required": ["buildings"],
  "properties": {
    "buildings": {
      "type": "array",
      "items": {
        "type": "object",
        "required": ["id", "name", "tier", "slots", "power"],
        "properties": {
          "id": { "type": "string" },
          "name": { "type": "string" },
          "tier": { "type": "integer", "minimum": 1, "maximum": 5 },
          "slots": { "type": "integer", "minimum": 0 },
          "power": { "type": "integer" }
        }
      }
    }
  }
}

🔧 Configuration

Adding a New JSON File

  1. Add schema to RefreshData/schemas/yourfile.schema.json
  2. Add task to DATA_TASKS array in refresh-data.js:
{
    type: 'json',
    source: 'yourfile.json',
    outputJs: 'yourfile-data.js',
    globalVar: 'yourfileData',
    schema: 'yourfile.schema.json'
}
  1. Run refresh: node refresh-data.js

Multi-Part Files

For large files split into parts:

{
    type: 'ship-components', // Custom type
    source: 'manifest.json',
    parts: ['part1.json', 'part2.json'],
    outputJs: 'output-data.js',
    outputJson: 'output-data.json',
    globalVar: 'outputData',
    schema: 'schema.json'
}

📈 Performance

Metric Value
Total processing time ~10-15 seconds
Files processed 10 tasks (78 JSON files)
Total data processed ~55 MB
Output generated ~65 MB
Schema validations 10 files
Change detections 10 files

🛡️ Benefits

Before (Original)

❌ No validation ❌ 6 files bypassed pipeline ❌ No change detection ❌ Silent failures ❌ Breaking changes undetected

After (Enhanced v2.0)

✅ Full JSON Schema validation ✅ ALL 11 files processed ✅ SHA-256 hash + structure tracking ✅ Detailed error messages ✅ Breaking change alerts ✅ Comprehensive reports ✅ CI/CD ready

🎓 Learning & Insights

Challenges Overcome

  1. Schema Flexibility: Some JSON files had optional fields or nullable values

    • Solution: Made schemas lenient with union types ["string", "null"]

  2. Large Files: ship-components files were 7+ MB each

    • Solution: Implemented streaming merge without loading full files into memory

  3. Complex Structures: Nested objects with dynamic keys

    • Solution: Used patternProperties in schemas

  4. Backward Compatibility: Existing apps fetching raw JSON

    • Solution: Keep both raw and processed files, gradual migration

Best Practices Established

  • ✅ Always validate before processing
  • ✅ Track changes with hashes
  • ✅ Generate actionable reports
  • ✅ Fail fast on breaking changes
  • ✅ Document schema expectations

🔮 Future Enhancements

Recommended

  1. Update Apps: Migrate apps to use processed Data/ files instead of raw JSON/

    • HubExplorer → crafting-hab-data.js
    • ShipExplorer → ship-formulas-data.js, ship-components-data.js
    • ClaimStakeExplorer → resource-tier-data.js

  2. CI/CD Integration: Add GitHub Actions workflow

    - name: Validate Data
  run: cd RefreshData && node refresh-data.js

  3. Schema Versioning: Track schema versions alongside data versions

  4. Diff Viewer: Create UI to visualize structural changes

  5. Auto-fix: Implement auto-migration for common breaking changes

Optional

  • Add TypeScript type generation from schemas
  • Create data quality metrics dashboard
  • Implement data compression for large files
  • Add incremental processing (only changed files)
