# Error Handler Generator Good error handling means custom error classes, proper status codes, and consistent response shapes. This tool generates all of it for your framework. **One command. Zero config. Just works.** ## Quick Start ```bash npx ai-error-handler express ``` ## What It Does - Generates error middleware for your framework - Creates custom error classes (NotFoundError, ValidationError, etc.) - Includes async wrapper to catch promise rejections - Sets up proper HTTP status codes ## Usage Examples ```bash # Express middleware npx ai-error-handler express # Fastify in JavaScript npx ai-error-handler fastify -l javascript # Next.js API routes npx ai-error-handler nextjs -o lib/errors.ts # Koa npx ai-error-handler koa ``` ## Best Practices - **Don't leak stack traces** - only show them in development - **Log errors server-side** - you need them for debugging - **Use error codes** - clients can handle specific codes - **Be consistent** - same error shape everywhere ## When to Use This - Starting a new API project - Standardizing error handling across routes - Adding proper error responses to a messy codebase - Setting up error monitoring ## Part of the LXGIC Dev Toolkit This is one of 110+ free developer tools built by LXGIC Studios. No paywalls, no sign-ups, no API keys on free tiers. Just tools that work. **Find more:** - GitHub: https://github.com/LXGIC-Studios - Twitter: https://x.com/lxgicstudios - Substack: https://lxgicstudios.substack.com - Website: https://lxgic.dev ## Requirements No install needed. Just run with npx. Node.js 18+ recommended. Needs OPENAI_API_KEY environment variable. ```bash npx ai-error-handler --help ``` ## How It Works Generates framework-specific error handling code including custom error classes, middleware, and async wrappers. The output follows best practices for each framework. ## License MIT. Free forever. Use it however you want.
