Error Handling APIs (Svelte)

These Svelte functions are used for capturing and managing exceptions from a reactive state.

exceptionRef()

Captures and manages exceptions (e.g., validation errors) from a reactive state, providing a reactive object of errors keyed by property path.

function exceptionRef<T extends ObjLike | Array<unknown>>(state: T): StateExceptionMap<T>;

• state: The reactive state to capture exceptions from.
• Returns: A StateExceptionMap containing current exception states.
