fastapi-error-handling

What problem does it solve?

Centralizes error handling for FastAPI to ensure consistent error responses and easier maintenance.

Core Features & Use Cases

• Centralized exception types (BusinessException, validation errors, database errors) with uniform JSON structure.
• Distinguishes 4xx client errors from 5xx server errors while masking sensitive details.
• Useful for APIs with multiple error types and business logic exceptions across many endpoints.
• Use cases include rich error metadata, structured error codes, and easy integration with logging.

Quick Start

• Install FastAPI-aware exception handling in your main app and register handlers.
• Define custom exception classes and their handlers, and apply them across routers.
• Example usage: raise BusinessException(...) and rely on handlers to format responses.
