data provider

28 Replies

Hi @Sly. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- A data provider in Refine acts as a bridge between your frontend application and your backend data source. It handles all data-related operations such as fetching, caching, creating, updating, and deleting records. The data provider encapsulates how the data is retrieved and makes HTTP requests to the backend. Key Concepts 1. Predefined Methods: A data provider must include several predefined methods that handle CRUD operations. These methods include: - create - createMany - deleteOne - deleteMany - getList - getMany - getOne - update - updateMany - custom - getApiUrl 2. Integration with Refine: Refine supports various built-in data providers for popular data sources like REST, Strapi, AirTable, Supabase, GraphQL, and more. You can also create your own data provider if needed. 3. Usage in Refine: To activate the data provider in a Refine application, you need to pass the dataProvider to the <Refine /> component. Example Here is an example of how to set up a data provider in a Refine application:

import { Refine } from "@refinedev/core";  
import { DataProvider } from "@refinedev/strapi-v4";  
import { authProvider, axiosInstance } from "./authProvider";  

function App() {  
  return (  
    <Refine  
      dataProvider={DataProvider(API_URL + `/api`, axiosInstance)}  
      //...  
    />  
  );  
}  

export default App;

import { Refine } from "@refinedev/core";  
import { DataProvider } from "@refinedev/strapi-v4";  
import { authProvider, axiosInstance } from "./authProvider";  

function App() {  
  return (  
    <Refine  
      dataProvider={DataProvider(API_URL + `/api`, axiosInstance)}  
      //...  
    />  
  );  
}  

export default App;

Source (https://refine.dev/blog/react-admin-tutorial/#data-provider) Creating a Custom Data Provider If you need to create your own data provider, you can define each method required for sending HTTP requests inside a dataProvider object. Here is a basic structure:

import { DataProvider } from "@refinedev/core";
const myDataProvider: DataProvider = {  
  getOne: async ({ resource, id }) => {  
    const response = await fetch(  
      `<https://example.com/api/v1/${resource}/${id}`,>  
    );  
    const data = await response.json();  
    return { data };  
  },  
  // other methods...  
};

import { DataProvider } from "@refinedev/core";
const myDataProvider: DataProvider = {  
  getOne: async ({ resource, id }) => {  
    const response = await fetch(  
      `<https://example.com/api/v1/${resource}/${id}`,>  
    );  
    const data = await response.json();  
    return { data };  
  },  
  // other methods...  
};

Source (https://refine.dev/docs/guides-concepts/general-concepts/#data-provider-) Built-in Data Providers Refine offers built-in data provider support for the most popular API providers. You can find the full list of supported data providers here (https://refine.dev/docs/packages/list-of-packages/#data-provider-packages). For more detailed information, you can refer to the Data Provider documentation (https://refine.dev/docs/data/data-provider/).

Which is the more efficient data provider i @kapa.ai which one is the more efficient data provider

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Determining the most efficient data provider depends on the specific requirements and context of your project. However, I can provide some insights based on the information available in the knowledge sources. Refine Data Provider Refine's data provider is designed to be flexible and efficient, supporting both REST and GraphQL backends. It leverages tools like graphql-request and gql-query-builder to create dynamic queries and mutations, which can be more efficient in terms of network usage and performance. #### Key Features: - Dynamic Queries: Built with gql-query-builder and graphql-request, allowing for dynamic query generation. - Comprehensive Methods: Supports a wide range of CRUD operations. - Integration with React Query: Manages data fetching, caching, and invalidation efficiently. Example of setting up a GraphQL data provider in Refine:

import { Refine } from "@refinedev/core";
import dataProvider from "@refinedev/strapi-v4";

const App = () => {
  return (
    <Refine
      dataProvider={dataProvider("<https://api.example.com">)}
      /* ... */
    >
      {/* ... */}
    </Refine>
  );
};

import { Refine } from "@refinedev/core";
import dataProvider from "@refinedev/strapi-v4";

const App = () => {
  return (
    <Refine
      dataProvider={dataProvider("<https://api.example.com">)}
      /* ... */
    >
      {/* ... */}
    </Refine>
  );
};

Source (https://refine.dev/blog/best-headless-cms/#refine-built-in-strapi-data-provider) React-Admin Data Provider React-Admin also supports GraphQL data providers but requires more manual configuration to avoid querying all entities by default, which can be inefficient. #### Key Features: - Customizable Queries: Allows overriding default queries to optimize data fetching. - Manual Configuration: Requires more setup to prevent over-fetching of data. Example of customizing a GraphQL query in React-Admin:

import buildGraphQLProvider, { buildQuery } from "ra-data-graphql-simple";
const myBuildQuery = (introspection) => (fetchType, resource, params) => {
  const builtQuery = buildQuery(introspection)(fetchType, resource, params);

  if (resource === "Command" && fetchType === "GET_ONE") {
    return {
      ...builtQuery,
      query: gql`
        query Command($id: ID!) {
          data: Command(id: $id) {
            id
            reference
            customer {
              id
              firstName
              lastName
            }
          }
        }
      `,
    };
  }

  return builtQuery;
};

export default buildGraphQLProvider({ buildQuery: myBuildQuery });

import buildGraphQLProvider, { buildQuery } from "ra-data-graphql-simple";
const myBuildQuery = (introspection) => (fetchType, resource, params) => {
  const builtQuery = buildQuery(introspection)(fetchType, resource, params);

  if (resource === "Command" && fetchType === "GET_ONE") {
    return {
      ...builtQuery,
      query: gql`
        query Command($id: ID!) {
          data: Command(id: $id) {
            id
            reference
            customer {
              id
              firstName
              lastName
            }
          }
        }
      `,
    };
  }

  return builtQuery;
};

export default buildGraphQLProvider({ buildQuery: myBuildQuery });

Source (https://refine.dev/blog/refine-vs-react-admin/#graphql-data-provider) Conclusion - Refine: Offers a more streamlined and efficient approach with built-in support for dynamic queries and integration with React Query, making it easier to manage data fetching and caching. - React-Admin: Provides flexibility but requires more manual configuration to optimize data fetching, which can complicate the project. For most use cases, Refine's data provider is likely to be more efficient due to its dynamic query capabilities and seamless integration with React Query. However, the best choice ultimately depends on your specific project requirements and preferences. For more detailed information, you can refer to the Refine Data Provider documentation (https://refine.dev/docs/data/data-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Im using strapi4 but when I activate the access control it slows rendering

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- When using Strapi v4 with Refine and activating access control, you might experience slow rendering due to the can method being executed for every row. This can lead to performance issues, especially if you have a large number of rows and each check involves an HTTP request. Performance Optimization Tips 1. Caching Access Control Checks: Refine uses react-query for data fetching and caching. You can configure the staleTime and cacheTime properties to cache access control checks, which can significantly improve performance.

   // inside your component
   const { data } = useCan({
     resource: "resource-you-ask-for-access",
     action: "action-type-on-resource",
     params: { foo: "optional-params" },
     queryOptions: {
       staleTime: 5 * 60 * 1000, // 5 minutes
       // ... other query options
     },
   });

   // inside your component
   const { data } = useCan({
     resource: "resource-you-ask-for-access",
     action: "action-type-on-resource",
     params: { foo: "optional-params" },
     queryOptions: {
       staleTime: 5 * 60 * 1000, // 5 minutes
       // ... other query options
     },
   });

Source (https://refine.dev/docs/authorization/access-control-provider/#performance) 2. Disable Access Control for Buttons: If the default behavior of checking access control for every row is unsuitable, you can disable it for specific buttons and manage it yourself according to your use case.

   <DeleteButton accessControl={false} />

   <DeleteButton accessControl={false} />

Source (https://github.com/refinedev/refine/issues/3945#issuecomment-1478061383) 3. Server-Side Pagination: If possible, enable server-side pagination to reduce the number of records fetched at once. This can help minimize the number of access control checks required. 4. Custom Access Control Logic: Implement custom logic to batch access control checks or optimize the can method to reduce the number of HTTP requests. Example of Disabling Access Control for Buttons

import { DeleteButton } from "@refinedev/antd";
const MyComponent = () => {
  return (
    <DeleteButton accessControl={false} />
  );
};

import { DeleteButton } from "@refinedev/antd";
const MyComponent = () => {
  return (
    <DeleteButton accessControl={false} />
  );
};

Additional Resources - Refine Access Control Provider Documentation (https://refine.dev/docs/authorization/access-control-provider/#performance) - GitHub Issue on Access Control Performance (https://github.com/refinedev/refine/issues/3946) By implementing these optimizations, you should be able to improve the rendering performance of your application when using access control with Strapi v4.

@kapa.ai what is staleTime

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- staleTime is a configuration option used in data fetching libraries like react-query (also known as TanStack Query) to control the freshness of cached data. When you set a staleTime, you define the duration for which the fetched data is considered fresh. During this period, the data will not be re-fetched from the server, even if a component re-renders or mounts. How staleTime Works - Fresh Data: Data is considered fresh for the duration specified by staleTime. - Stale Data: Once the staleTime has elapsed, the data is considered stale, and a new fetch will be triggered the next time the data is requested. Usage in Refine In Refine, you can use the staleTime option to optimize performance, especially when dealing with access control checks or other frequent data fetches. By setting an appropriate staleTime, you can reduce the number of network requests and improve the responsiveness of your application. Example Here is an example of how to use staleTime with the useCan hook in Refine:

import { useCan } from "@refinedev/core";

// inside your component
const { data } = useCan({
  resource: "resource-you-ask-for-access",
  action: "action-type-on-resource",
  params: { foo: "optional-params" },
  queryOptions: {
    staleTime: 5 * 60 * 1000, // 5 minutes
    // ... other query options
  },
});

import { useCan } from "@refinedev/core";

// inside your component
const { data } = useCan({
  resource: "resource-you-ask-for-access",
  action: "action-type-on-resource",
  params: { foo: "optional-params" },
  queryOptions: {
    staleTime: 5 * 60 * 1000, // 5 minutes
    // ... other query options
  },
});

In this example, the access control check result will be considered fresh for 5 minutes. During this time, the cached result will be used, and no new network request will be made for the same check. Documentation Links - Refine Access Control Provider Documentation (https://refine.dev/docs/authorization/access-control-provider/#performance) - TanStack Query useQuery Documentation (https://tanstack.com/query/v4/docs/react/reference/useQuery) By configuring staleTime appropriately, you can significantly improve the performance of your Refine application by reducing unnecessary data fetching. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai populate only id

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To populate only the id field in a Strapi v4 data provider using Refine, you can use the meta parameter to specify the fields you want to fetch. This can be particularly useful when you want to minimize the amount of data transferred and improve performance. Example Here is an example of how to configure the useTable hook to fetch only the id field for all posts:

import { List, EditButton, ShowButton, useTable } from "@refinedev/antd";
import { Table, Space } from "antd";

const PostList = () => {
  const { tableProps, sorter } = useTable<IPost>({
    meta: {
      fields: ["id"],
    },
  });

  return (
    <List>
      <Table {...tableProps} rowKey="id">
        <Table.Column dataIndex="id" title="ID" />
        <Table.Column
          title="Actions"
          dataIndex="actions"
          render={(_, record) => (
            <Space>
              <EditButton hideText size="small" recordItemId={record.id} />
              <ShowButton hideText size="small" recordItemId={record.id} />
            </Space>
          )}
        />
      </Table>
    </List>
  );
};

export default PostList;

import { List, EditButton, ShowButton, useTable } from "@refinedev/antd";
import { Table, Space } from "antd";

const PostList = () => {
  const { tableProps, sorter } = useTable<IPost>({
    meta: {
      fields: ["id"],
    },
  });

  return (
    <List>
      <Table {...tableProps} rowKey="id">
        <Table.Column dataIndex="id" title="ID" />
        <Table.Column
          title="Actions"
          dataIndex="actions"
          render={(_, record) => (
            <Space>
              <EditButton hideText size="small" recordItemId={record.id} />
              <ShowButton hideText size="small" recordItemId={record.id} />
            </Space>
          )}
        />
      </Table>
    </List>
  );
};

export default PostList;

In this example, the meta parameter is used to specify that only the id field should be fetched for each post. This configuration ensures that the data returned from the Strapi API includes only the id field, reducing the amount of data transferred and potentially improving performance. Documentation Links - Strapi v4 Fields Selection Documentation (https://refine.dev/docs/data/packages/strapi-v4/#fields-selection) By using the meta parameter to specify the fields you want to fetch, you can optimize your data fetching strategy and improve the performance of your Refine application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai populate role.name to use accessControlProvider

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To populate the role.name field in a Strapi v4 data provider and use it with the accessControlProvider in Refine, you can configure the meta parameter to include the role relation and its name field. This allows you to fetch the necessary role information for access control checks. Step-by-Step Guide 1. Configure the authProvider to Fetch Role Information: Ensure that your authProvider fetches the role information, including the name field, when retrieving the user data.

   const strapiAuthHelper = AuthHelper(API_URL + "/api");

   strapiAuthHelper.me("token", {
     meta: {
       populate: ["role"],
     },

       populate: ["role"],
     },
   });

Source (https://refine.dev/docs/data/packages/strapi-v4/#relations-population-for-me-request) 2. Implement the accessControlProvider: Use the fetched role information in your accessControlProvider to determine access permissions.

   import { newEnforcer } from "casbin";

@kapa.ai how to fetch only the user id and role name: const { data, status } = await strapiAuthHelper.me(tokens, { meta: { populate: ["role"], }, });

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To fetch only the user id and role.name using the strapiAuthHelper.me method in Refine, you can use the meta parameter to specify the fields you want to populate. Here is how you can achieve this: Step-by-Step Guide 1. Configure the authProvider to Fetch User ID and Role Name: Use the meta parameter to specify that you want to populate the role relation and fetch only the id and role.name fields.

   const strapiAuthHelper = AuthHelper(API_URL + "/api");

   const { data, status } = await strapiAuthHelper.me(token, {
     meta: {
       populate: {
         role: {
           fields: ["name"],
         },
       },
       fields: ["id"],
     },
   });

   if (status === 200) {
     const { id, role } = data;
     const roleName = role?.name;
     return {
       id,
       roleName,
     };
   }

   return null;

   const strapiAuthHelper = AuthHelper(API_URL + "/api");

   const { data, status } = await strapiAuthHelper.me(token, {

     const roleName = role?.name;
     return {
       id,
       roleName,
     };
   }

   return null;

Explanation - meta.populate: Specifies the relations to populate. In this case, it populates the role relation and fetches only the name field of the role. - meta.fields: Specifies the fields to fetch for the user. In this case, it fetches only the id field. Example Usage in authProvider Here is how you can integrate this into your authProvider:

``javascript
import { AuthProvider } from "@refinedev/core";
import { AuthHelper } from "@refinedev/strapi-v4";
import { API_URL, TOKEN_KEY } from "./constants";
import axios from "axios";

Let me check the knowledge base for you. One moment! :books: ---------------------- When handling a login request with Strapi and Refine, you might encounter a situation where a 400 response does not return an error message. To handle this properly, you can check the response status and extract the error message from the response data if available. Here is an updated version of your login method that handles 400 errors and extracts the error message:

import { AuthProvider } from "@refinedev/core";
import { AuthHelper } from "@refinedev/strapi-v4";
import { API_URL, TOKEN_KEY } from "./constants";
import axios from "axios";

export const axiosInstance = axios.create();
const strapiAuthHelper = AuthHelper(API_URL + "/api");

export const authProvider: AuthProvider = {
  login: async ({ email, password }) => {
    try {
      const { data, status } = await strapiAuthHelper.login(email, password);
      if (status === 200) {
        localStorage.setItem(TOKEN_KEY, data.jwt);

        // set header axios instance
        axiosInstance.defaults.headers.common[
          "Authorization"
        ] = `Bearer ${data.jwt}`;

        return {
          success: true,
          redirectTo: "/",
        };
      }
    } catch (error) {
      if (error.response && error.response.status === 400) {
        return {
          success: false,
          error: {
            message: error.response.data?.error?.message || "Login failed",
            name: "Invalid email or password",
          },
        };
      }
      return {
        success: false,
        error: {
          message: "An unexpected error occurred",
          name: "Login Error",
        },
      };
    }
  },
  // other methods...
};

import { AuthProvider } from "@refinedev/core";
import { AuthHelper } from "@refinedev/strapi-v4";
import { API_URL, TOKEN_KEY } from "./constants";
import axios from "axios";

export const axiosInstance = axios.create();
const strapiAuthHelper = AuthHelper(API_URL + "/api");

export const authProvider: AuthProvider = {
  login: async ({ email, password }) => {
    try {
      const { data, status } = await strapiAuthHelper.login(email, password);
      if (status === 200) {
        localStorage.setItem(TOKEN_KEY, data.jwt);

        // set header axios instance
        axiosInstance.defaults.headers.common[
          "Authorization"
        ] = `Bearer ${data.jwt}`;

        return {
          success: true,
          redirectTo: "/",
        };
      }
    } catch (error) {
      if (error.response && error.response.status === 400) {
        return {
          success: false,
          error: {
            message: error.response.data?.error?.message || "Login failed",
            name: "Invalid email or password",
          },
        };
      }
      return {
        success: false,
        error: {
          message: "An unexpected error occurred",
          name: "Login Error",
        },
      };
    }
  },
  // other methods...
};

Explanation - Try-Catch Block: The try-catch block is used to handle any errors that occur during the login request. - Error Handling: Inside the catch block, we check if the error response status is 400. If it is, we extract the error message from the response data. If no specific error message is available, a default message "Login failed" is used. - Default Error Handling: If the error is not a 400 status or if there is no response data, a generic error message "An unexpected error occurred" is returned. By implementing this error handling logic, you can ensure that meaningful error messages are returned to the user when a login attempt fails. For more information on handling errors in Refine, you can refer to the Refine documentation (https://refine.dev/docs/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai 'error' is of type 'unknown'

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- When TypeScript infers the type of error as unknown, you need to explicitly type it to handle it properly. You can use type assertions to specify that error is of type any or a more specific type if you know the structure of the error object. Here is an updated version of your login method with proper error handling and type assertions:

import { AuthProvider } from "@refinedev/core";
import { AuthHelper } from "@refinedev/strapi-v4";
import { API_URL, TOKEN_KEY } from "./constants";
import axios from "axios";

export const axiosInstance = axios.create();
const strapiAuthHelper = AuthHelper(API_URL + "/api");

export const authProvider: AuthProvider = {
  login: async ({ email, password }) => {
    try {
      const { data, status } = await strapiAuthHelper.login(email, password);
      if (status === 200) {
        localStorage.setItem(TOKEN_KEY, data.jwt);

        // set header axios instance
        axiosInstance.defaults.headers.common[
          "Authorization"
        ] = `Bearer ${data.jwt}`;

        return {
          success: true,
          redirectTo: "/",
        };
      }
    } catch (error) {
      const err = error as any; // Type assertion to 'any'
      if (err.response && err.response.status === 400) {
        return {
          success: false,
          error: {
            message: err.response.data?.error?.message || "Login failed",
            name: "Invalid email or password",
          },
        };
      }
      return {
        success: false,
        error: {
          message: "An unexpected error occurred",
          name: "Login Error",
        },
      };
    }
  },
  // other methods...
};

import { AuthProvider } from "@refinedev/core";
import { AuthHelper } from "@refinedev/strapi-v4";
import { API_URL, TOKEN_KEY } from "./constants";
import axios from "axios";

export const axiosInstance = axios.create();
const strapiAuthHelper = AuthHelper(API_URL + "/api");

export const authProvider: AuthProvider = {
  login: async ({ email, password }) => {
    try {
      const { data, status } = await strapiAuthHelper.login(email, password);
      if (status === 200) {
        localStorage.setItem(TOKEN_KEY, data.jwt);

        // set header axios instance
        axiosInstance.defaults.headers.common[
          "Authorization"
        ] = `Bearer ${data.jwt}`;

        return {
          success: true,
          redirectTo: "/",
        };
      }
    } catch (error) {
      const err = error as any; // Type assertion to 'any'
      if (err.response && err.response.status === 400) {
        return {
          success: false,
          error: {
            message: err.response.data?.error?.message || "Login failed",
            name: "Invalid email or password",
          },
        };
      }
      return {
        success: false,
        error: {
          message: "An unexpected error occurred",
          name: "Login Error",
        },
      };
    }
  },
  // other methods...
};

Explanation - Type Assertion: The error object is asserted as any using const err = error as any;. This allows you to access the properties of the error object without TypeScript throwing type errors. - Error Handling: The rest of the error handling logic remains the same, ensuring that meaningful error messages are returned to the user. By using type assertions, you can handle the error object properly and ensure that your TypeScript code compiles without issues. For more information on handling errors in Refine, you can refer to the Refine documentation (https://refine.dev/docs/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how to display the error notification on the top

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To display error notifications at the top of the screen in a Refine application, you can use the NotificationProvider and customize the notification's placement. Refine integrates with various UI libraries, and the approach may vary slightly depending on the library you are using. Below is an example using Ant Design, which is one of the supported UI libraries in Refine. Step-by-Step Guide 1. Set Up NotificationProvider: Ensure that you have the NotificationProvider set up in your application. This provider is required for displaying notifications.

   import { Refine } from "@refinedev/core";
   import { notificationProvider } from "@refinedev/antd";

   const App = () => {
     return (
       <Refine
         notificationProvider={notificationProvider}
         // other props
       >
         {/* other components */}
       </Refine>
     );
   };

   export default App;

   import { Refine } from "@refinedev/core";
   import { notificationProvider } from "@refinedev/antd";

   const App = () => {
     return (
       <Refine
         notificationProvider={notificationProvider}
         // other props
       >
         {/* other components */}
       </Refine>
     );
   };

   export default App;

2. Customize Error Notification: Customize the error notification to display at the top of the screen. You can do this by specifying the placement property in the notification configuration.

   import { useNotification } from "@refinedev/core";

   const { open } = useNotification();

   const showErrorNotification = (message, description) => {
     open?.({
       message,
       description,
       type: "error",
       placement: "topRight", // Customize the placement
     });
   };

   import { useNotification } from "@refinedev/core";

   const { open } = useNotification();

   const showErrorNotification = (message, description) => {
     open?.({
       message,
       description,
       type: "error",
       placement: "topRight", // Customize the placement
     });
   };

3. Handle Errors in Your AuthProvider: Use the showErrorNotification function to display error notifications when handling errors in your authProvider.

   import { AuthProvider } from "@refinedev/core";
   import { AuthHelper } from "@refinedev/strapi-v4";
   import { API_URL, TOKEN_KEY } from "./constants";
   import axios from "axios";
export const axiosInstance = axios.create();
   const strapiAuthHelper = AuthHelper(API_URL + "/api");

   export const authProvider: AuthProvider = {
     login: async ({ email, password }) => {
       try {
         const { data, status } = await strapiAuthHelper.login(email, password);
         if (status === 200) {
           localStorage.setItem(TOKEN_KEY, data.jwt);

           // set header axios instance
           axiosInstance.defaults.headers.common[
             "Authorization"
           ] = `Bearer ${data.jwt}`;

           return {
             success: true,
             redirectTo: "/",
           };
         }
       } catch (error) {
         const err = error as any; // Type assertion to 'any'
         if (err.response && err.response.status === 400) {
           showErrorNotification(
             "Login failed",
             err.response.data?.error?.message || "Invalid email or password"
           );
           return {
             success: false,
             error: {
               message: "Login failed",
               name: "Invalid email or password",
             },
           };
         }
         showErrorNotification(
           "An unexpected error occurred",
           "Login Error"
         );
         return {
           success: false,
           error: {
             message: "An unexpected error occurred",
             name: "Login Error",
           },
         };
       }
     },
     // other methods...
   };

   import { AuthProvider } from "@refinedev/core";
   import { AuthHelper } from "@refinedev/strapi-v4";
   import { API_URL, TOKEN_KEY } from "./constants";
   import axios from "axios";
export const axiosInstance = axios.create();
   const strapiAuthHelper = AuthHelper(API_URL + "/api");

   export const authProvider: AuthProvider = {
     login: async ({ email, password }) => {
       try {
         const { data, status } = await strapiAuthHelper.login(email, password);
         if (status === 200) {
           localStorage.setItem(TOKEN_KEY, data.jwt);

           // set header axios instance
           axiosInstance.defaults.headers.common[
             "Authorization"
           ] = `Bearer ${data.jwt}`;

           return {
             success: true,
             redirectTo: "/",
           };
         }
       } catch (error) {
         const err = error as any; // Type assertion to 'any'
         if (err.response && err.response.status === 400) {
           showErrorNotification(
             "Login failed",
             err.response.data?.error?.message || "Invalid email or password"
           );
           return {
             success: false,
             error: {
               message: "Login failed",
               name: "Invalid email or password",
             },
           };
         }
         showErrorNotification(
           "An unexpected error occurred",
           "Login Error"
         );
         return {
           success: false,
           error: {
             message: "An unexpected error occurred",
             name: "Login Error",
           },
         };
       }
     },
     // other methods...
   };

Example Usage Here is a complete example of how to set up and use the error notification: ```javascript import { Refine, AuthProvider, useNotification } from "@refinedev/core"; import { notificationProvider } from "@refinedev/antd"; import { AuthHelper } from "@refinedev/strapi-v4"; import axios from "axios"; const API_URL = " ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
