Sorting out a `groq` query for resolved image URL and dimensions

Last updated: Sep 27, 2021
Hi, I'm trying to sort out a
groq
query that would give me a resolved image url, along with the image width and height. I noticed I could get some of what I want with the V1 version of the api like so:

*[_type == 'teamMember' && !(_id in path('drafts.**'))]
{'headshot': {'url': headshot.image.asset->url, 'alt': headshot.alt}, ...} 
But that doesn't seem to work with the latest version of the API. Would also still need a way to get the width and height of the image.

That should work. Btw, the image width and height is part of its
_ref
/
_id
 
// "image-3ff0bac8a44b902c4ba9548ba0a18ac215f14857-2880x1920-png"
const [assetType, _id, dimensions, filetype] = headshot.image.asset._ref.split('-')
const [width, height] = dimensions.split('x')

What do you get when you query?

const [width, height] = dimensions.split('x')

At the moment, I'm just playing around in the "Vision" gui, and this is what is returned from the query I posted above:

"headshot":{3 items

When I switch to v1, I see 👇
Sep 27, 2021, 6:53 PM
"headshot":{2 items
"alt":"headshot"
"url":"<https://cdn.sanity.io/images/abc123/production/947080633821852c01e1ad03e1afd8b4435c34df-674x606.png>"
}

Ah, this is subtle, but it’s because the
started overwriting the fields in
v2021-03-25
so if you change your query to:
*[_type == 'teamMember' && !(_id in path('drafts.**'))]
{..., 'headshot': {'url': headshot.image.asset->url, 'alt': headshot.alt}} 
It should probably work
Sep 27, 2021, 6:59 PM
Because you’re overwriting a key with this projection
Sep 27, 2021, 6:59 PM
*[_type == 'teamMember' && !(_id in path('drafts.**'))]
{..., headshot{'url': headshot.image.asset->url, 'alt': headshot.alt}} 

☝️ This is the same btw
