How to get dataset name in Sanity v3?

In Sanity Studio v3, the Parts System has been completely replaced, so you can no longer use import client from "part:@sanity/base/client". Instead, you have a few modern approaches to get your dataset configuration:

Using the useClient hook

The most common approach in v3 is to use the useClient hook within React components:

import { useClient } from 'sanity'

function MyComponent() {
  const client = useClient({ apiVersion: '2023-05-24' })
  const dataset = client.config().dataset
  
  // Use dataset...
}

Important: Since useClient is a React hook, it must be called inside a React component or custom hook - you can't use it at the module level.

Alternative: Direct config import

If you need to access the dataset outside of a React component (like in a utility file), you can import your configuration directly:

import { dataset } from './sanity.config'

// Use dataset...

Your sanity.config.ts (or .js) file should export your configuration:

import { defineConfig } from 'sanity'

export default defineConfig({
  projectId: 'your-project-id',
  dataset: 'production',
  // ... other config
})

// You can also export individual values
export const { dataset, projectId } = defineConfig({
  projectId: 'your-project-id',
  dataset: 'production',
})

For App SDK applications

If you're building with the App SDK, import from @sanity/sdk-react instead:

import { useClient } from '@sanity/sdk-react'

const client = useClient({ apiVersion: '2023-05-24' })
const dataset = client.config().dataset

The v3 migration removed the old parts-based import system in favor of standard JavaScript imports and React hooks, which provides better TypeScript support and a more modern development experience.
