Api Error Handling

This gives you a complete error handling system with standardized response formats, custom error classes, and observability built in. You get a full ERROR_CODES map, middleware for Express and Flask, retry strategies with exponential backoff, circuit breaker patterns, and Sentry integration. The guides cover everything from basic validation errors to production monitoring with error rate metrics. Use it when you're tired of inconsistent error responses across your API or when debugging production issues without proper request tracing. The best part is the field validation approach that returns all errors at once instead of making clients fix them one at a time.
