SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides comprehensive guidelines and code patterns for implementing robust error handling in TypeScript applications, ensuring applications fail gracefully and provide meaningful feedback.

Core Features & Use Cases

Custom Error Classes: Define reusable, typed error classes (e.g., ValidationError, NotFoundError).
Error Handling Patterns: Implement safe try-catch blocks for synchronous and asynchronous code.
Recovery Strategies: Understand retry logic and circuit breaker patterns for external service interactions.
Use Case: When an API request fails due to a validation error, this Skill helps ensure the correct error type is thrown, logged, and a user-friendly message is returned, preventing application crashes.

Quick Start

Implement custom error classes like ValidationError and NotFoundError in your TypeScript project.

FAQPage Schema

How do I handle API errors and external service failures in TypeScript?▼

To handle API errors in TypeScript, this Skill provides recovery strategies like retry logic and circuit breaker patterns to manage external service failures gracefully. It ensures proper error logging and user-friendly feedback without crashing the application.

What's the best way to create custom error classes in TypeScript?▼

The best way to create custom error classes in TypeScript is to define reusable, typed classes such as ValidationError or NotFoundError. This approach ensures proper error stack trace preservation and allows for targeted error handling logic.

How do I prevent unhandled promise rejections in asynchronous TypeScript code?▼

You prevent unhandled promise rejections by implementing safe try-catch patterns specifically designed for asynchronous operations. These patterns ensure all promise rejections are caught, logged, and processed with appropriate error types.

Does TypeScript try-catch preserve the error stack trace when throwing custom errors?▼

Yes, TypeScript try-catch patterns preserve the error stack trace when throwing custom errors correctly. This Skill provides guidelines for proper error class creation to ensure stack traces remain intact during synchronous and asynchronous operations.

When should I use circuit breaker patterns for TypeScript error handling?▼

Use circuit breaker patterns for TypeScript error handling when your application interacts with external services prone to failure. This strategy prevents cascading failures by stopping requests to a failing service, allowing it to recover.
