Type-Safe TypeScript Development FAQs

Question 1

Does this skill work with older TypeScript versions?

Accepted Answer

While it includes modern features like TS 5.5 inferred predicates, many core patterns apply to TS 4.9+; however, TS 5.2+ is recommended for full feature support like the 'using' keyword.

Question 2

How does this skill handle error management?

Accepted Answer

It promotes the Result type pattern, making errors explicit in the return type rather than relying on hidden exceptions, which forces the caller to handle potential failure states.

Question 3

Can I use this for non-TypeScript projects?

Accepted Answer

No, this skill is specifically optimized for TypeScript development and focuses on type-system features, strict compiler configurations, and runtime validation libraries like Zod.

Question 4

What is the policy on using 'any' with this skill?

Accepted Answer

The skill strictly prohibits 'any' and encourages the use of 'unknown' combined with type guards or assertion functions to maintain a robust and predictable type system.

Question 5

Why does it prefer Zod over standard interfaces for external data?

Accepted Answer

Standard interfaces are discarded at compile-time. Zod provides runtime validation at the boundaries of your application (like API calls), ensuring that external data actually matches your types.
