import { useNavigationHistory } from "next-navigation-history"

const SamplePage: NextPage = () => {
const [value, setValue] = useState({})
const [info, setInfo] = useState("")

// If you just want to get a navigationHistory
const nav = useNavigationHistory()

// If you want to backup and restore state
const nav = useNavigationHistory(() => {
// Backup state
return { value }
})

// NavigationHistory is not accessible on the server side
useEffect(() => {
// Restore backup state
const state = nav.state
if (state) {
setValue(state.value)
}

// Get info value sent by the transition source.
const info = nav.info
if (info) {
setInfo(info)
}
}, [])

function next() {
// Send info value to the transition destination.
nav.back("send infomation!")
