How does this skill handle async errors in Express?

It utilizes an asyncHandler wrapper that automatically catches rejected promises and passes them to the next() middleware, preventing server crashes from unhandled rejections.

What about retrying failed network operations?

The skill includes a utility function for exponential backoff, allowing your application to automatically and safely retry transient failures like database or API timeouts.

Does it include production monitoring practices?

Yes, it provides patterns for centralized logging, production-safe error responses that hide stack traces, and process-level handlers for graceful service management.

Can I distinguish between operational and programming errors?

Yes, the skill implements an isOperational flag in custom error classes to separate expected runtime errors (like 404s) from unexpected programming bugs.

API 개발

Implements resilient error management strategies for Node.js applications using custom classes, async patterns, and centralized Express middleware.

소개

This skill equips Claude with specialized patterns for building robust Node.js backends that fail gracefully. It provides standardized implementations for custom operational error classes, centralized Express error middleware, and async wrapper functions to prevent unhandled promise rejections. By integrating process-level handlers and exponential backoff retry logic, this skill ensures applications remain stable under failure conditions while providing meaningful debugging feedback and secure production logs.
