Use selectFromResult with normalized data

I suspect the answer is “no”, but I would like your confirmation: it does make sense to use selectFromResult with normalized data?

Like:

export const commentaryAdapter = createEntityAdapter({
  // Assume IDs are stored in a field other than `book.id`
  selectId: commentary => commentary.attributes.id,
});

 const { selectAll: selectAllCommentaries, selectById: selectCommentaryById } =
    commentaryAdapter.getSelectors(state => {
      return selectCommentaryEvents(state);
    });

  const commentaries = useSelector(state => selectAllCommentaries(state));

const { commentaryEvents } =
    useGetMatchResultQuery(
      {
        matchId: matchId,
      },
      {
        selectFromResult: result => {
          return {
            ...result,
            commentaryEvents: commentaries,
          };
        },
      },
    );

Or, if you use normalized data, selectFromResult doesn’t make sense?

Yeah, so what I was saying applies here.

If you do nothing, by default const { data } = useMyQuery() will give you back the entire {ids: [], entities: {} structure you returned from transformResponse.

If you only want part of that, like a single item by its ID, then you should use selectFromResult to pick out just that one piece.

You’d want to use the entity adapter selectors. Specifically, you’d need to use the “localized” versions, generated by calling myAdapter.getSelectors() without an input selector:

And then const allItemsAsArray = selectors.selectAll(res.data) in transformResponse.
