//this code snippet solve the problem with frontend refresh when you write the cache with PostForm:

//in Home.js use this:
	const [posts, setPosts] = useState([]);
	const { user } = useContext(AuthContext);
	const { loading, data } = useQuery(FETCH_POSTS_QUERY);
	useEffect(() => {
		if (data) {
			setPosts(data.getPosts);
		}

Group Array of JavaScript Objects by Key or Property Value

Implementation

const groupBy = key => array =>
  array.reduce((objectsByKeyValue, obj) => {
    const value = obj[key];
    objectsByKeyValue[value] = (objectsByKeyValue[value] || []).concat(obj);
    return objectsByKeyValue;

//note: month is 0 based, just like Dates in js
function getWeeksInMonth(year, month) {
  const weeks = [],
    firstDate = new Date(year, month, 1),
    lastDate = new Date(year, month + 1, 0),
    numDays = lastDate.getDate();

  let dayOfWeekCounter = firstDate.getDay();

  for (let date = 1; date <= numDays; date++) {
