# Fetch followers count by user ID

> Get the total follower count for any user by their ID

## Overview

Returns a function that fetches the total follower count of any user, identified by `userId`. This is a public endpoint — authentication is not required.

## Usage Example

```tsx theme={null}
import { useFetchFollowersCountByUserId } from "@replyke/react-js";

function UserStats({ userId }: { userId: string }) {
  const fetchFollowersCountByUserId = useFetchFollowersCountByUserId();
  const [count, setCount] = useState<number | null>(null);

  useEffect(() => {
    fetchFollowersCountByUserId({ userId }).then((res) => setCount(res.count));
  }, [userId]);

  return <span>{count ?? "..."} followers</span>;
}
```

## Parameters

The hook returns a function. That function accepts:

<ParamField path="userId" type="string" required>
  The ID of the user whose follower count to fetch.
</ParamField>

## Returns

<ResponseField name="count" type="number">
  Total number of followers for the specified user.
</ResponseField>
