firebase snapshot: return specific fields only

[Douwe van Dijk]

Hi All,

I am not sure if this is already implemened or added as a feature request for the WEB api, but is there a way to only return specific childs in the snapshot (e.g. what the _.without function does in underscore ). In some cases I need to access a root element but do not need to whole object to be returned. 

Regards, D.

Hi Douwe,

The Firebase database is architected in such a way that you will always fetch the entire child tree of a given location when fetching any data from that location. We try to build our APIs so that things that are expensive for the database feel expensive in the API, and this is one of them.

I'd recommend reading over best practices for structuring data and pinging this group with any specific data structure questions you come across when building your app.

Cheers!

Michael
