What are the best practices for error handling in TypeScript?

What are the best practices for error handling in TypeScript?

In TypeScript, it's important to use try-catch blocks for synchronous code and to handle promises with .catch() for asynchronous code.

Can you explain how to use custom error classes?

Certainly! You can create custom error classes by extending the built-in Error class. This allows you to add additional properties and methods.

What about using union types for error handling?

Using union types can help you define a specific set of errors that a function can throw, making your error handling more predictable.

How can I ensure type safety in my error handling?

You can ensure type safety by defining specific error types and using TypeScript's type guards to narrow down the error types in your catch blocks.

Any tools or libraries you recommend for better error handling?

Yes, libraries like 'ts-error' or 'zod' can help with structured error handling and validation in TypeScript.
