[Solved] Firebase – How to order items?

Question

You must must use orderedByChild by the key of the date you’d like to order the children by. You can then observe the Value or ChildAdded event type of this query to retrieve the children in ascending order of date. To have the most recent first, you must reverse the objects manually client-side. Otherwise, you could prepend a - symbol to all the dates and handle it client side.
