I have the following data in firebase:

{
 items: [
    { 
      title: 'Some title 1',
      createAt: 1630359921518
    },
    { 
      title: 'Some title 2',
      createAt: 1630359921518
    },
 ]
 
}

I want to order these items them by their createAt date. How can I a query it? Thanks

    You cannot get a single field from a document at first place. You would have to get the document and then sort is using Javascript. Another option would be to store those array elements in a sub-collection so you can order them by createdAt field and also limit number of results to be fetched. Commented Aug 31, 2021 at 17:53
