Graphql query - Order by related category title

[pnpaes]

Hi, I have an entry that has a few category fields.
When fetching data using Graphql, is it possible to achieve something like this orderBy:"category_filed.title desc" ?
I know that the example above will not work, but is there an alternative?

This is not possible out of the box.

You could achieve it using the Preparse Field plugin, though. With the plugin installed, create a new Preparse field that stores the related category’s title. Then add the field to your entry type’s field layout, and resave your entries using the php craft resave/entries command. Then you can order your entries based on the Preparse field’s handle.
