function resource<T, R>(options: ResourceOptions<T, R> & { defaultValue: NoInfer<T>; }): ResourceRef<T>;

Constructs a Resource that projects a reactive request to an asynchronous operation defined by a loader function, which exposes the result of the loading operation via signals.

Note that resource is intended for read operations, not operations which perform mutations. resource will cancel in-progress loads via the AbortSignal when destroyed or when a new request object becomes available, which could prematurely abort mutations.
