feat(query) enable support for DocumentSnapshot with start/endAt

See original GitHub issue

What is the feature? enable passing a DocumentSnapshot to a query https://firebase.google.com/docs/reference/js/firebase.firestore.Query#start-at

Do you have thoughts/examples on how the feature would be used (i.e. API)?

I’m trying to implement a table that allows me to page through the documents returned by a query. Because of duplication of properties of the documents I cannot reliable use these properties to paginate. I need to use startAt/endAt with an actual DocumentSnapshot passed to ensure I am not missing any documents. This behaviour is talked about in the firestore docs

Thank you @goleary

I have found my mistake. I set document data as a key for QuerySnapshot instead of intended DocumentSnapshot. I even forgot to add the responding unit test to test if snapshot is right for the inner data.

@goleary Thanks for reaching out - I reached out to @illumnist over gitter for more detail.

How did you end up using it? Would you mind sharing the app logic?
