Proper way to enforce a single document type in Sanity schema, with deprecation warning for deskTool.

Hey Sanity Team. I am new to using sanity and am wanting to implement a single document type in my schema for my authors. I was looking at the following guide https://www.sanity.io/guides/singleton-document but when I tried to implement it, I got a deprecation warning for deskTool in sanity/desk. What is the proper way to enforce that the author can only implement a single document for one of my schema types? (ex. wanting to make the document for text on a webpage)

You are on the right track however like you noticed there is a deprecation warning, switch sanity/desk for sanity/structure.
Or you could use the following plugin -
https://www.sanity.io/plugins/singleton-tools , just used on one of my projects and it's amazing

O snap, I will take a look. Thanks!

Oh hey! I made that plugin. Glad you like it!

Works like charm! Could be just because I am new, but if you impose the singleton option on a schema, how do you make it so that there is a new single document by default? Do I have to create the doc before I set the option?

If you use the

singletonDocumentListItem

in your structure it’ll create a singleton with whatever

id

you pass in the first time you open it.
