To initiate a new Sanity Studio project or upgrade an existing one, please refer to our comprehensive guide on Installing and Upgrading Sanity Studio.

If you are updating from a version earlier than 3.37.0, you should also check out this article to ensure your dependencies are up to date.

With the new defineQuery utility it is no longer necessary to pass generics into client.fetch calls for the sanity typegen command to generate type definitions for query results. 🥳 Update @sanity/client to v6.21.0 or later, then add "overloadClientMethods": true to your sanity-typegen.json configuration file, and finally wrap your query strings in the new defineQuery utility method from groq:

import {createClient} from '@sanity/client'
-import groq from 'groq'
+import {defineQuery} from 'groq'
-import type { SettingsQueryResult } from "~/sanity.types";

const client = createClient({ /* ... */ })

-const settingsQuery = groq`
+const settingsQuery = defineQuery(`
  *[_type == "settings"][0]
-`
+`)

-const settings = await client.fetch<SettingsQueryResult>(settingsQuery)
+const settings = await client.fetch(settingsQuery)
