Using next.js with next following code in _app.tsx:

```jsx
import { Box, ChakraProvider, useColorModeValue } from '@chakra-ui/react'
import type { AppProps } from 'next/app'
import Head from 'next/head'
import { DefaultSeo } from 'next-seo'
import { getSeo } from 'lib/getSeo'
import customTheme from 'configs/theme'
import { EmotionCache } from '@emotion/cache'

import createEmotionCache from 'lib/createEmotionCache'
import { useRouter } from 'next/router'
import { ackeeConfig } from 'configs/ackee-config'
import { useEffect, useMemo } from 'react'
import * as ackeeTracker from 'ackee-tracker'

interface MyAppProps extends AppProps {
emotionCache?: EmotionCache
}

const clientSideEmotionCache = createEmotionCache()
const { server, options, domainId } = ackeeConfig
function MyApp({
Component,
pageProps,
emotionCache = clientSideEmotionCache,
}: MyAppProps) {
const seo = getSeo()
const mode = useColorModeValue('light', 'dark')
const router = useRouter()

let instance: any = useMemo(() => {
if (typeof window !== 'undefined') {
return ackeeTracker.create(server, options)
}
}, [])

useEffect(() => {
const attributes = ackeeTracker.attributes(options.detailed)
const url = new URL(router.asPath, location as any)

const { stop } = instance.record(domainId, {
...attributes,
siteLocation: url.href,
})
return () => {
stop()
}
}, [router.asPath])
