Use the QueryClientProvider component to connect and provide a QueryClient to your application:

import { QueryClient, QueryClientProvider } from 'react-query'
const queryClient = new QueryClient()
function App() {
return <QueryClientProvider client={queryClient}>...</QueryClientProvider>


  • client: QueryClient
    • Required
    • the QueryClient instance to provide
  • contextSharing: boolean
    • defaults to false
    • Set this to true to enable context sharing, which will share the first and at least one instance of the context across the window to ensure that if React Query is used across different bundles or microfrontends they will all use the same instance of context, regardless of module scoping.
