Common Use Cases

1. Display Recent Specs Dashboard

async function getRecentSpecsForDashboard() {
  const response = await fetch(
    'https://api.pre.dev/list-specs?limit=10',
    { headers: { 'Authorization': 'Bearer YOUR_API_KEY' } }
  );
  const data = await response.json();
  
  return data.specs.map(spec => ({
    id: spec._id,
    title: spec.input.substring(0, 80) + '...',
    type: spec.endpoint === 'fast_spec' ? 'Fast' : 'Deep',
    status: spec.status,
    createdAt: new Date(spec.created),
    url: spec.humanSpecUrl
  }));
}

2. Monitor Failed Specs

def check_failed_specs(client):
    """Check for failed specs in the last 24 hours."""
    failed = client.list_specs(status='failed', limit=100)
    
    recent_failures = []
    for spec in failed['specs']:
        created = datetime.fromisoformat(spec['created'].replace('Z', '+00:00'))
        if datetime.now(timezone.utc) - created < timedelta(hours=24):
            recent_failures.append({
                'id': spec['_id'],
                'input': spec['input'],
                'error': spec.get('errorMessage', 'Unknown error'),
                'created': created
            })
    
    return recent_failures

3. Export Completed Specs

async function exportCompletedSpecs() {
  const allCompleted = [];
  let skip = 0;
  const limit = 50;

  while (true) {
    const response = await fetch(
      `https://api.pre.dev/list-specs?status=completed&skip=${skip}&limit=${limit}`,
      { headers: { 'Authorization': 'Bearer YOUR_API_KEY' } }
    );
    const data = await response.json();
    
    allCompleted.push(...data.specs);
    
    if (!data.hasMore) break;
    skip += limit;
  }

  return allCompleted;
}

4. Build Pagination Component

interface PaginationState {
  currentPage: number;
  pageSize: number;
  totalItems: number;
  items: SpecObject[];
}

async function loadPage(
  pageNumber: number,
  pageSize: number,
  filters?: ListSpecsOptions
): Promise<PaginationState> {
  const client = new SpecClient('YOUR_API_KEY');
  const response = await client.listSpecs({
    ...filters,
    skip: pageNumber * pageSize,
    limit: pageSize
  });

  return {
    currentPage: pageNumber,
    pageSize,
    totalItems: response.total,
    items: response.specs
  };
}

Best Practices

Pagination

Use reasonable page sizes (20-50 specs)
Cache results when appropriate
Show loading states while fetching

Filtering

Combine filters to reduce result sets
Use status=completed for user-facing spec lists
Use status=failed for debugging/monitoring

Performance

Don’t fetch all specs at once if you have many
Use pagination for large datasets
Consider implementing infinite scroll with skip parameter

Error Handling

Always check response status codes
Handle empty result sets gracefully
Show appropriate messages when no specs match filters

Next: Find Specs (Search)

Search specs using regex patterns for advanced filtering.
