Defining a schema
The Sanity Studio can only interact with documents in a dataset for which it has schema types registered in its configuration. It currently has none.
1Create a new document type
Create a new file in your Studio’s schemaTypes folder called postType.ts with the code below which contains a set of fields for a new post document type.
import {defineField, defineType} from 'sanity'
export const postType = defineType({
name: 'post',
title: 'Post',
type: 'document',
fields: [
defineField({
name: 'title',
type: 'string',
validation: (rule) => rule.required(),
}),
defineField({
name: 'slug',
type: 'slug',
options: {source: 'title'},
validation: (rule) => rule.required(),
}),
defineField({
name: 'publishedAt',
type: 'datetime',
initialValue: () => new Date().toISOString(),
validation: (rule) => rule.required(),
}),
defineField({
name: 'image',
type: 'image',
}),
defineField({
name: 'body',
type: 'array',
of: [{type: 'block'}],
}),
],
})2Register the post schema type to the Studio schema
Now you can import this document type into the schemaTypes array in the index.ts file in the same folder.
import {postType} from './postType'
export const schemaTypes = [postType]3Publish your first document
When you save these two files, your Studio should automatically reload and show your first document type. Click the + symbol at the top left to create and publish a new post document.
