• 💡 Clean, colorful CLI output with progress indicators
• 📁 Export differences to JSON files for further analysis
• 🔧 Simple command-line interface

🔄 Workflow Examples

Development to Production Comparison

# Compare your development environment against production
pnpm dlx firestore-indexes-diff --source dev-indexes.json --target prod-indexes.json

Staging Environment Sync

# Ensure staging has all the indexes from development
pnpm dlx firestore-indexes-diff --source dev-indexes.json --target staging-indexes.json

CI/CD Integration

# In your CI pipeline, validate index completeness
- name: Check Firestore Index Completeness
  run: |
    # Export current production indexes
    firebase firestore:indexes > prod-indexes.json
    
    # Export your project's indexes
    firebase firestore:indexes --project ${{ env.PROJECT_ID }} > current-indexes.json
    
    # Check for missing indexes
    pnpm dlx firestore-indexes-diff --source current-indexes.json --target prod-indexes.json
    
    # Fail if differences found
    if [ -f "diff-indexes.json" ]; then
      echo "Missing indexes detected!"
      cat diff-indexes.json
      exit 1
    fi

Multi-Environment Validation

# Check multiple environments in sequence
environments=("dev" "staging" "prod")
for env in "${environments[@]}"; do
  echo "Checking $env environment..."
  pnpm dlx firestore-indexes-diff \
    --source master-indexes.json \
    --target "$env-indexes.json"
done
