No QueryClient set, use QueryClientProvider to set one Nextjs new cli command error

Hi @KLB. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The error "No QueryClient set, use QueryClientProvider to set one" typically occurs when the React Query client is not properly set up in your application. This is a common issue when using refine with Next.js. Here are the steps to resolve this issue: 1. Ensure react-query is installed: Make sure you have react-query installed in your project. You can install it using npm or yarn:

   npm install @tanstack/react-query
   # or
   yarn add @tanstack/react-query

   npm install @tanstack/react-query
   # or
   yarn add @tanstack/react-query

2. Wrap your application with QueryClientProvider: You need to wrap your application with QueryClientProvider and pass the QueryClient instance to it. Here is an example of how to do this in your _app.js or _app.tsx file:

   import { useState, useMemo } from 'react';
   import { AppProps } from 'next/app';
   import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
   import { Refine } from '@refinedev/core';

   type NextPageWithLayout<P = object, IP = P> = NextPage<P, IP> & {
     noTemplate?: boolean;
     getLayout?: (page: ReactElement, pageProps: AppProps) => ReactNode;
   };

   type ExtendedAppProps = AppProps & {
     Component: NextPageWithLayout;
   };

   function MyApp({ Component, pageProps }: ExtendedAppProps): JSX.Element {
     const [queryClient] = useState(() => new QueryClient());

     const getLayout = useMemo(
       () => Component.getLayout ?? ((page: ReactElement) => page),
       [Component]
     );

     const ComponentWithLayout: React.FC<{ children: JSX.Element }> = ({ children }) => {
       return getLayout(children, pageProps);
     };
return (
       <QueryClientProvider client={queryClient}>
         <Refine
           options={{
             reactQuery: {
               clientConfig: queryClient,
             },
           }}
         >
           <ComponentWithLayout>
             <Component {...pageProps} />
           </ComponentWithLayout>
         </Refine>
       </QueryClientProvider>
     );
   }

   export default MyApp;

   import { useState, useMemo } from 'react';
   import { AppProps } from 'next/app';
   import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
   import { Refine } from '@refinedev/core';

   type NextPageWithLayout<P = object, IP = P> = NextPage<P, IP> & {
     noTemplate?: boolean;
     getLayout?: (page: ReactElement, pageProps: AppProps) => ReactNode;
   };

   type ExtendedAppProps = AppProps & {
     Component: NextPageWithLayout;
   };

   function MyApp({ Component, pageProps }: ExtendedAppProps): JSX.Element {
     const [queryClient] = useState(() => new QueryClient());

     const getLayout = useMemo(
       () => Component.getLayout ?? ((page: ReactElement) => page),
       [Component]
     );

     const ComponentWithLayout: React.FC<{ children: JSX.Element }> = ({ children }) => {
       return getLayout(children, pageProps);
     };
return (
       <QueryClientProvider client={queryClient}>
         <Refine
           options={{
             reactQuery: {
               clientConfig: queryClient,
             },
           }}
         >
           <ComponentWithLayout>
             <Component {...pageProps} />
           </ComponentWithLayout>
         </Refine>
       </QueryClientProvider>
     );
   }

   export default MyApp;

3. Check your layout components: Ensure that any component using useQueryClient is a child of the QueryClientProvider. For example, if you have a layout component, it should be structured like this:

   import { useQueryClient } from '@tanstack/react-query';

   const Layout: React.FC<{ children: ReactElement }> = ({ children }) => {
     const queryClient = useQueryClient();
     return <div>{children}</div>;
   };

   export default Layout;

   import { useQueryClient } from '@tanstack/react-query';

   const Layout: React.FC<{ children: ReactElement }> = ({ children }) => {
     const queryClient = useQueryClient();
     return <div>{children}</div>;
   };

   export default Layout;

4. Refer to refine's Next.js example: If you are still facing issues, you can refer to the with-nextjs example provided by refine. You can clone this example to your local machine using the following command:

   npm create refine-app@latest -- --example with-nextjs

   npm create refine-app@latest -- --example with-nextjs

By following these steps, you should be able to resolve the "No QueryClient set, use QueryClientProvider to set one" error in your Next.js application using refine. For more details, you can refer to the related documentation and examples: - Refine Documentation on Query Client Configuration (https://refine.dev/docs/api-reference/core/components/refine-config/#clientconfig) - GitHub Issue #5014 (https://github.com/refinedev/refine/issues/5014) - [ ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
