hide-unsafe-assertions

To hide unsafe type assertions from a public TypeScript API, wrap the internal type assertions inside well-typed functions. This narrows the scope of unsafe code to the implementation, preserving a clean public interface without leaking assertions.

Your TypeScript function signature exposes internal type assertions when implementation details like any or type casts leak into the public contract. You must internalize these checks within the function body to keep the external type signatures clean.

The best way to handle necessary type assertions without breaking type safety is to validate unsafe points locally within the implementation. Hiding internal assertions prevents runtime errors while keeping public TypeScript types stable and clean.

Yes, you can use internal type assertions while maintaining a clean external TypeScript contract. By applying hidden assertions inside well-typed functions, you ensure the unsafe implementation details do not leak into the public API.

You need to hide type assertions in TypeScript codebases when function implementations require any or unsafe casts, but the public API must remain strictly typed. This isolates the unsafe code to prevent runtime errors while preserving type stability.

The limitation of hiding unsafe code in TypeScript implementations is that it requires local validation at unsafe points to prevent runtime errors. While the public type signature remains clean, the internal logic still relies on assertions that the compiler cannot verify.
