Two Tiny Utils for the Result Pattern
TL;DR
Two small utility functions for handling the Result pattern in TypeScript were introduced, inspired by Rust's error handling approach. These helpers streamline error management in TypeScript projects, enhancing code reliability.
✦ Why It Matters
Implement these utility functions in your TypeScript projects to enhance error handling today.
Key Takeaways
- Use tryCatch to simplify error handling in async functions.
- Implement safeExec to ensure functions returning Result do not throw.
- Adopt a layered approach to error management in applications.
- Avoid excessive try/catch blocks for cleaner code.
How It Works
The tryCatch function takes an asynchronous function as input, executes it, and returns a structured Result indicating success or error. This reduces redundancy in error handling across service functions.
Similarly, safeExec wraps functions that already return a Result, ensuring that any unexpected errors are caught and returned in the same format.
