Multiple sorted `ids` arrays by `createEntityAdapter`

[guswnsxodlf]

Hello,

I am using createEntityAdapter on my app, and I need to sort the entities I got from the server, using many different sort functions.

Currently, createEntityAdapter only supports a single ids array and a single sortcomparer.

I managed this by making different selectors which get the sorted entities array (using selectAll) from the reducer and sort it in a different way.

However, it is not normalized structure since I can't get a sorted ids, but sorted entities.

Is there any way to have multiple ids arrays with a single entities lookup table?

For example,

type Book = { bookId: string; title: string; author: string }

const booksAdapter = createEntityAdapter<Book>({
  selectId: (book) => book.bookId,
  // ids arrays sorted based on book titles, and also on  **author names**.
  sortComparer: [
    sortFuncByTitleAsc,
    sortFuncByAuthorAsc,
  ],
})

Thanks.

There's nothing built in, no. This looks related to #799 .

Note that you could have one sort function that does multiple comparison steps at once.
