Start with [installation and basic usage](https://docs.univer.ai/guides/sheets/getting-started/installation.md). This example uses Next.js App Router to mount Univer Sheets in a container with an explicit height.

Load the editor from a Client Component with `ssr: false`. A `use client` directive alone does not disable prerendering. [Next.js](https://nextjs.org/docs/app/guides/lazy-loading#skipping-ssr).

### Integration Steps

1. Initialize Univer in the `useEffect` hook
2. Destroy Univer in the return function of the `useEffect` hook

### Example

Each mount uses its own child container. Disposal runs in a microtask after the surrounding React cleanup, so nested React roots are not unmounted synchronously during a React commit.

```tsx title="app/editor/univer-editor.tsx"
'use client'

import { UniverSheetsCorePreset } from '@univerjs/preset-sheets-core'
import UniverPresetSheetsCoreEnUS from '@univerjs/preset-sheets-core/locales/en-US'
import { createUniver, LocaleType, mergeLocales } from '@univerjs/presets'
import { useEffect, useRef } from 'react'

import '@univerjs/preset-sheets-core/lib/index.css'

export default function UniverEditor() {
  const containerRef = useRef<HTMLDivElement>(null)

  useEffect(() => {
    const host = containerRef.current
    if (!host) return
    const container = document.createElement('div')
    container.style.height = '100%'
    host.append(container)

    const { univer, univerAPI } = createUniver({
      locale: LocaleType.EN_US,
      locales: {
        [LocaleType.EN_US]: mergeLocales(
          UniverPresetSheetsCoreEnUS,
        ),
      },
      presets: [
        UniverSheetsCorePreset({
          container,
        }),
      ],
    })

    univerAPI.createWorkbook({})

    return () => {
      queueMicrotask(() => {
        univer.dispose()
        container.remove()
      })
    }
  }, [])

  return (
    <div ref={containerRef} style={{ height: 600 }} />
  )
}
```

```tsx title="app/editor/page.tsx"
'use client'

import dynamic from 'next/dynamic'

const UniverEditor = dynamic(() => import('./univer-editor'), { ssr: false })

export default function Page() {
  return <UniverEditor />
}
```
