Overview

useFetchEntityReactionsWrapper is a stateful wrapper around useFetchEntityReactions that manages pagination and reaction list state for you. Use it to build “who reacted” UIs — for example, a modal showing all users who upvoted a post, with infinite scroll. By default the hook does not fetch on mount. Set autoFetch: true to start fetching immediately, or call refetch() manually when you’re ready (e.g., when a modal opens).

​
Usage Example

import { useFetchEntityReactionsWrapper } from "@replyke/react-js";

function WhoReacted({ entityId }: { entityId: string }) {
  const { reactions, loading, hasMore, loadMore, refetch } =
    useFetchEntityReactionsWrapper({
      entityId,
      reactionType: "upvote",
      limit: 20,
      autoFetch: true,
    });

  return (
    <div>
      <ul>
        {reactions.map((r) => (
          <li key={r.id}>{r.user?.username}</li>
        ))}
      </ul>
      {hasMore && (
        <button onClick={loadMore} disabled={loading}>
          Load more
        </button>
      )}
    </div>
  );
}
