api-versioning
by dadbodgeoff
Implement API versioning strategies for backward compatibility. Covers URL versioning, header versioning, and deprecation workflows.
api-client
by dadbodgeoff
Centralized TypeScript API client with typed namespaces, automatic token refresh with request deduplication, TanStack Query integration, and consistent error handling.
error-handling
by dadbodgeoff
Implement consistent error handling with custom error classes, error boundaries, and structured error responses. Covers logging, monitoring, and user-friendly messages.
data-transformers
by dadbodgeoff
Centralized transformation logic for consistent data shaping across API routes. Includes aggregators, rankers, trend calculators, and data sanitizers.
