For my posts

in component AboutUsers.jsx

  const [users, setUsers] = useState([]);

if I write like this, it’s working, I see posts in users:

in component AboutUsers.jsx

 useEffect(()=> {
        const getUsers = axios.get('https://jsonplaceholder.typicode.com/todos',{
            params:{
                _limit:limitPage,
                _page:currentPage
            }
        })
            .then(response => setUsers(response.data))
    },[])

but I created other component PostMyServise.js with:

export default class PostMyServise {

    static async getPost(limit=10, page=1) {
        const result  = await axios.get('https://jsonplaceholder.typicode.com/todos',{
            params: {
                _limit: limit,
                _page: page,
            }
    })
            .then(response => {
                return response
            })
        return result;
    }
}

And one yet component useCreatePosts.js:

export const usePosts = (callback) => {
   const [isTrue, setIsTrue] = useState('')
   const [error, setError] = useState('')


   const createPost = async () => {
       try {
           setIsTrue(false);
           await callback;
       } catch (e) {
               setError(e.message);
       } finally {
               setIsTrue(true);
       }
   }
return [createPost, isTrue, error];
}

export default usePosts;

I wrote this, and I see empty array in console.log(users):

I don’t understand why array is empty

  const [createPost, isTrue, error] = usePosts (async ()=> {
        const response = await PostMyServise.getPost(limitPage, currentPage);
        setUsers(response.data)
    })

 useEffect(() => {
            createPost();
        },[currentPage])

>Solution :

You are not calling the callback. You need to add the parentheses.

   const createPost = async () => {
       try {
           setIsTrue(false);
           await callback();
       } catch (e) {
               setError(e.message);
       } finally {
               setIsTrue(true);
       }
   }

I feel like something about your code is over-engineered and too complex but that’s outside the scope of the question. This change will at least get it working. Also, I suggest changing the name of isTrue and setIsTrue to something more meaningful as those names do not tell you what they are for.
