# Fetch comment reactions
> Fetch a paginated list of users who reacted to a comment
export const SpaceReputationParams = ({variant = "context", field = "path"}) => {
const isUser = variant === "user";
return <>
Opt-in. Adds a spaceReputation number to each returned user,
scoped to a single space. Requires the reputation bundle.
The reputation total is always present regardless;{" "}
spaceReputation is purely additive and only appears when you
pass this object. This object is the primary form — it
replaces the deprecated flat props below. See the{" "}
Reputation data model for the
full contract.
{isUser ?
Which bucket to read. A space <uuid> reads that
space's bucket; "none" reads the
project-general (space-less) bucket.{" "}
"context" is rejected (400) on this
endpoint — there is no space context to derive. The empty string
and the legacy general / null aliases are
also rejected. Missing buckets read as 0.
:
Which bucket to read. One of: a space <uuid>{" "}
(that space's bucket), "none" (the
project-general, space-less bucket), or{" "}
"context" (the space derived from the
request context — resolved per-row on lists, or the single space on
member/team/conversation surfaces). The empty string and the legacy{" "}
general / null aliases are rejected (400).
Missing buckets read as 0.
}
Only honored when spaceId is an explicit space <uuid>.
When true, spaceReputation is the{" "}
subtree sum — the named space plus all of its
descendant spaces (the root space's own bucket included). Ignored for{" "}
"none"; not allowed with "context".
{isUser ? Deprecated — use the spaceReputation{" "}
object instead. The flat form of spaceReputation.spaceId.
Still accepted (the object wins if both are passed); removal is a later
major version. Accepts a space <uuid> or "none" only —{" "}
"context" is rejected (400) on this endpoint.

## Overview
`useFetchCommentReactions` returns a function that fetches individual reaction records for a comment. Use this to show "who reacted" lists, optionally filtered by a specific reaction type.
Authentication is optional — the endpoint works without a token. When the
caller is signed in, reactions from users with a block between them and the
caller, in either direction, are excluded from both the results and the
count. Block filtering requires the `moderation` bundle.
## Usage Example
```tsx theme={null}
import { useFetchCommentReactions } from "@sublay/react-js";
import { useState } from "react";
function CommentLikers({ commentId }: { commentId: string }) {
const fetchReactions = useFetchCommentReactions();
const [reactions, setReactions] = useState([]);
const load = async () => {
const res = await fetchReactions({ commentId, page: 1, reactionType: "like" });
setReactions(res.data);
};
return ;
}
```
## Parameters
The comment to fetch reactions for.
Page number (1-indexed).
Results per page. Default: `20`.
Filter to a specific reaction type.
Sort direction by creation date. Default: `"desc"`.
## Returns
Array of reaction records. Each includes `id`, `userId`, `reactionType`, `targetId`, `targetType`, `createdAt`. The `user` field is populated when user data is available; when `spaceReputation` is requested it carries an added `spaceReputation` number. See [Reputation](/v8/data-models/reputation).
Pagination metadata for the result set.
* `page` — current page number
* `pageSize` — number of results returned
* `totalItems` — total number of reactions matching the query
* `totalPages` — total number of pages
* `hasMore` — whether additional pages are available
