import { createFrontConnection } from 'front-broker-connection'
import {
  FrontConnection,
  FrontPayload
} from 'front-broker-connection/dist/utils/types'

// ...

const [frontConnection, setFrontConnection] = useState<FrontConnection | null>(
  null
)

useEffect(() => {
  setFrontConnection(createFrontConnection(options))
}, [])

useEffect(() => {
  if (authLink) {
    frontConnection?.openLink(authLink)
  }
}, [frontConnection, authLink])
