GROQ Query - Can you Join an Array of Strings into a Single Output String?

7 replies
Last updated: Jul 27, 2022
Hi all, does anyone know of a way in groq to join an array of strings into a single output string? Sorry if I've missed something obvious!
This query produces an array of strings, but I would like "sectors" to produce a string with a single comma separated list. Thanks as always for the help.

*[_type == "technologyProduct"]{
   "sectors": targetIndustries[]->title,
}

Pretty sure it’s not possible.

Thanks Kitty- good to know- I'll work around it!

Maybe these 2 links can help you, but I don’t think you can do so, unless you flatten the array in your front end with 
array.toString()
.

Or 
array.join(', ')
. 🙂

I think you could also set a patch even with a custom document action and get your array of strings (or however you want it to be saved) patched into another field.

Thanks all. I can work around it on the front end, but I was hoping to shape the data in the query and avoid the need to create another component. Not a major headache!

you don’t need a new component… that’s a quick function you could use for setting the data into a component.
