What is the common mistake when destructuring error results?

When you destructure { data, error }, the 'error' variable is the raw error value. To return it as a Result, you must wrap it using Err(error) to maintain type consistency.

Is tryAsync always asynchronous?

Yes, tryAsync returns a Promise and must always be awaited to retrieve the Result object, unlike traditional try-catch blocks.

How do I return a fallback value if an error occurs?

In the catch block of trySync or tryAsync, you can return Ok(fallbackValue) to provide a valid recovery value that matches your function's return type.

Why use trySync/tryAsync instead of traditional try-catch?

These functions provide better type safety and force explicit error handling by returning a Result object, making your code more predictable and preventing unhandled exceptions.

API Development

Standardizes error management using trySync and tryAsync patterns for type-safe, graceful recovery in TypeScript.

This skill equips Claude with specialized patterns for robust error management using the wellcrafted library, moving away from traditional, unpredictable try-catch blocks toward a structured Result-based architecture. It provides clear guidance on using trySync for synchronous operations and tryAsync for asynchronous tasks, ensuring better type safety, explicit error propagation, and cleaner fallback logic. By following these implementation patterns, developers can handle failures more gracefully and maintain consistent error states across their entire codebase.
