SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Configures global error handling for .NET and Python backend applications.

Core Features & Use Cases

Centralizes exception capture across ASP.NET Core and FastAPI.
Uses RFC 7807 ProblemDetails format for consistent error responses with environment-aware detail levels.
Provides a generation flow that outputs a GlobalExceptionMiddleware (or FastAPI exception handlers), custom exceptions, and registration code.

Quick Start

Provide the project root and environment to generate the middleware, exception types, and registration code for integration.

FAQPage Schema

How do I configure global error handling for FastAPI and ASP.NET Core backends?▼

Global error handling for FastAPI and ASP.NET Core is configured by generating and registering centralized exception middleware that captures errors and maps them to standardized HTTP responses.

What is RFC 7807 ProblemDetails and how does it standardize API error responses?▼

RFC 7807 ProblemDetails is a standardized format for API error responses that provides consistent, client-friendly error details. It adjusts detail levels based on the environment for secure development vs production behavior.

How do I map custom exceptions to HTTP status codes in Python and .NET?▼

To map custom exceptions to HTTP status codes in Python and .NET, generated exception models and GlobalExceptionMiddleware intercept errors and translate them into appropriate HTTP statuses with standardized responses.

Can I use the same exception handling pattern across both FastAPI and ASP.NET Core projects?▼

Yes, you can use the same centralized exception handling pattern across FastAPI and ASP.NET Core. It generates environment-aware middleware and exception handlers tailored for each framework's registration requirements.

Does global exception middleware support different detail levels for development and production environments?▼

Global exception middleware supports environment-aware behavior, providing detailed error responses during development and restricted, client-friendly outputs in production to prevent sensitive data exposure.

What's the best way to generate and register FastAPI exception handlers?▼

The best way to generate and register FastAPI exception handlers is by providing your project root and environment to produce the middleware, custom exception types, and integration registration code automatically.
