Example Quality Assessment

✅ Comprehensive Examples

Every endpoint includes:

Basic cURL request
Query parameter variations
Response schema with real data
Error handling examples
Frontend integration (React/TypeScript)

Example:

# Basic request
curl http://localhost:3005/api/health/media/coverage

# With environment parameter
curl 'http://localhost:3005/api/health/media/coverage?environment=dev'

# React integration
const { data } = useQuery(['media-coverage'], () =>
  fetch('/api/health/media/coverage').then(r => r.json())
);

✅ Real-World Data

All examples use actual data from the 3,740 NHL parts:

67.03% have 360° views (2,507 parts)
66.87% have gallery images (2,501 parts)
59.73% have FRONT images (2,234 parts)
27.3 point quality score difference (with vs without media)

Content team workflows (shoot lists, enrichment pipeline)
Product manager insights (coverage targets, gap analysis)

Usage Scenarios

For Developers

Getting Started:

Read MEDIA_COVERAGE_API.md - Quick Start section
Import Postman collection
Test endpoints locally
Review TypeScript types
Follow JSDoc guide for code documentation

Building Features:

// Use typed API response
import type { MediaCoverageReport } from './types/media';

async function fetchCoverage(): Promise<MediaCoverageReport> {
  const response = await fetch('/api/health/media/coverage');
  const json = await response.json();

  if (!json.success) {
    throw new Error(json.error.message);
  }

  return json.data;
}

For Product Managers

Understanding Media Coverage:

Read "Overview" and "Data Model" sections in MEDIA_COVERAGE_API.md
Review "Use Cases for Product Managers"
Run Postman collection to see live data
Analyze gaps endpoint for enrichment opportunities

Key Insights:

67% of parts have 360° views (industry-leading)
Parts with media score 27.3 points higher
FRONT images have 60% coverage (target: 80%)

For Content Teams

Generating Shoot Lists:

Use /gaps endpoint with minQuality=80
Filter by mediaType=view360 for 360° photography
Export to CSV for content pipeline
Track progress with distribution endpoint

Prioritization:

# High-priority parts (score ≥ 85, missing 360°)
curl 'http://localhost:3005/api/health/media/gaps?minQuality=85&mediaType=view360&limit=50' | \
  jq '.data.gaps[] | {sku, title, priority: .enrichmentPriority}' > shoot_list.json

For DevOps

Deployment:

Review Performance section
Set up Redis caching (10-minute TTL)
Configure MongoDB indexes
Enable monitoring (Prometheus metrics)

Health Checks:

# Service health
curl http://localhost:3005/health

# Coverage endpoint latency
time curl http://localhost:3005/api/health/media/coverage

Next Steps

Phase 1: API Development (Current)

Status: Documentation Complete ✅

Remaining Tasks:

Implement repository methods (getCoverageSummary, getDistribution, getGaps)
Create route handlers
Add MongoDB aggregation pipelines
Write unit tests
Write integration tests

Phase 2: Frontend Integration

Tasks:

Create React components using documented APIs
Implement dashboard with coverage charts
Build gaps table with prioritization
Add export to CSV functionality
Set up error boundaries

Phase 3: PDF Integration (Future)

Tasks:

Scan GCS bucket for PDFs
Extract metadata with pdf-parse
Enrich MongoDB collection
Verify API (counts will auto-populate)
No frontend changes needed (backwards compatible)

Timeline: 2-4 weeks after PDF data becomes available
