How to use entries() with linked entry IDs?

How can I use client.entries() with linked entry fields?

See https://support.contentful.com/hc/en-us/articles/200513278-How-do-I-add-categories-to-my-content-?page=1#comment_202252446 for use case.

Going for another interptetation: If you want to get all Entries of type A which are in a certain category if type B this should work:

client.entries({
  include: 1,
  'fields.linkToCategoryOfTypeB.sys.id': 'idOfCategory'
});

As @sdepold said, you can’t query for properties within the category, but you can still look for entries that link to a certain category ID.
