This ternary expression is redundant. The checkIdField function already handles cases where options is undefined by returning undefined. You can simplify this to a direct call to checkIdField(options).

Suggested change
const idField = options ? checkIdField(options) : undefined;
const idField = checkIdField(options);

Declining: the ternary guard at the call site is intentional. checkIdField and checkOptions are typed to expect a real ReactFireOptions object, and the hooks handle the no-options case before calling them. Widening the signatures to accept undefined would require options: ReactFireOptions | undefined since field follows as a required parameter, which isn't a meaningful improvement. The current shape keeps the function signatures strict.
