What problem does it solve?

When optional LLM or third-party API calls fail in Elysia.js routes, throwing unhandled errors leads to generic 500 HTTP responses, leaving users with unactionable error messages and breaking non-critical optional features that should not disrupt core request functionality.

Core Features & Use Cases

• Result Object Pattern: Returns typed success/failure objects for service calls instead of throwing exceptions, eliminating unhandled 500 errors for optional dependencies.
• Custom Error Responses: Lets route handlers define custom HTTP status codes and structured error payloads for failed LLM/API calls.
• Use Case: Ideal for Elysia backends with optional AI features like document analysis, content generation, or third-party integrations where service failures should only impact the optional feature, not the entire request.

Quick Start

Use this skill to add graceful LLM fallback logic to your Elysia.js document parsing route so users see clear, actionable error messages when the AI service is unavailable instead of generic 500 errors.
