I built a MERN project where the component FrindListWidget is called under 2 conditions.

1. If it is the user's own friends list, the widget will be rendered and the status in Redux user.friends will be updated.
2. If it is another user, only the widget will be rendered. Redux state is not updated.

Each Friend also contains a , which will add or remove Friend. Apparently, everything was working fine until I checked the Network tab in Chrome Developer Tools. I detected that friends was called an infinite number of times. To make it clear, I wrote console.log("friends",friends);. Yes, it has been recorded numerous times. I share the following code:

FriendListWidget.jsx

//other mui imports
import { WidgetWrapper } from "../../../components/StyledComponent/WidgetWrapper";
import { useEffect, useState } from "react";
import { useDispatch, useSelector } from "react-redux";
import { setFriends as setUsersFriends } from "../../../Redux/Slices/authSlice";
import { userRequest } from "../../../requestMethod";

import Friend from "../../../components/Friend";

const FriendListWidget = ({ userId }) => {
  const dispatch = useDispatch();
  const { palette } = useTheme();
  const [friends, setFriends] = useState([]);
  const user = useSelector((state) => state.user);

  const getFriends = async () => {
    const res = await userRequest.get(`/users/${userId}/friends`);
    const data = await res.data;
    if (user._id === userId) {
      dispatch(setUsersFriends({ friends: data }));
      setFriends(data);
    } else {
      setFriends(data);
    }
  };

  useEffect(() => {
    getFriends();
    // eslint-disable-next-line react-hooks/exhaustive-deps
  }, [user, userId]);

  console.log("friends", friends); //This is being logged for infinite times

  return (
    <WidgetWrapper>
      <Typography
        color={palette.neutral.dark}
        variant="h5"
        fontWeight="500"
        sx={{ mb: "1.5rem" }}
      >
        Friend List
      </Typography>
      <Box display="flex" flexDirection="column" gap="1.5rem">
        {friends.map((friend) => (
          <Friend
            key={friend._id}
            friendId={friend._id}
            name={`${friend.firstName} ${friend.lastName}`}
            subtitle={friend.occupation}
            userPicturePath={friend.picturePath}
          />
        ))}
      </Box>
    </WidgetWrapper>
  );
};

export default FriendListWidget;

Friend.jsx

//other mui imports
import { useDispatch, useSelector } from "react-redux";
import { useNavigate } from "react-router-dom";
import { userRequest } from "../../requestMethod";
import { setFriends } from "../../Redux/Slices/authSlice";
import { FlexBetween } from "../StyledComponent/FlexBetween";
import UserImage from "../StyledComponent/UserImage";

const Friend = ({ friendId, name, location, userPicturePath }) => {
  const dispatch = useDispatch();
  const navigate = useNavigate();
  const { _id } = useSelector((state) => state.user);
  const friends = useSelector((state) => state.user.friends);

  const { palette } = useTheme();
  const primaryLight = palette.primary.light;
  const primaryDark = palette.primary.dark;
  const main = palette.neutral.main;
  const medium = palette.neutral.medium;

  const isFriend = friends.find((friend) => friend._id === friendId);
  const isUser = friendId === _id;

  const patchFriend = async () => {
    const res = await userRequest.patch(`/users/${_id}/${friendId}`);
    const data = await res.data;
    dispatch(setFriends({ friends: data }));
  };

  return (
    <FlexBetween>
      <FlexBetween gap="1rem">
        <UserImage image={userPicturePath} size="55px" />
        <Box
          onClick={() => {
            navigate(`/profile/${friendId}`);
            navigate(0);
          }}
        >
          <Typography
            color={main}
            variant="h5"
            fontWeight="500"
            sx={{
              "&:hover": {
                color: palette.primary.light,
                cursor: "pointer",
              },
            }}
          >
            {name}
          </Typography>
          <Typography color={medium} fontSize="0.75rem">
            {location}
          </Typography>
        </Box>
      </FlexBetween>
      {!isUser && (
        <IconButton
          onClick={() => patchFriend()}
          sx={{ backgroundColor: primaryLight, p: "0.6rem" }}
        >
          {isFriend ? (
            <PersonRemoveOutlined sx={{ color: primaryDark }} />
          ) : (
            <PersonAddOutlined sx={{ color: primaryDark }} />
          )}
        </IconButton>
      )}
    </FlexBetween>
  );
};

export default Friend;

userRequest is just an axios method:

export const userRequest = axios.create({
  baseURL: BASE_URL,
  headers: { token: `Bearer ${token}` },
});

I tried removing the dependency in the useEffect hook:

useEffect(() => {
    getFriends();
    // eslint-disable-next-line react-hooks/exhaustive-deps
  }, []);

However, it only renders once. It will not show updates via at runtime. I have to reload the window to see the update.
