Best way to access custom methods on a dataProvider

We have a dataProvider that looks like-

const nestCrudProvider = dataProviderNestjsxCrud(API_URL);
const dataProvider = {
    ...nestCrudProvider,
    message: {
        getHelloWorld: async () => {
            return {
                data: 'Hello World'
            }
        },
        addTriggerToMessage: async (record: BaseRecord) => {
            return {
                ...record,
                trigger: "Added Trigge to Message"
            }
        },
        setAccess: async (record: BaseRecord) => {
            return {
                ...record,
                trigger: "Set Access to Message"
            }
        }
    },
    panel: {
        getHelloWorld: async () => {
            return {
                data: 'Hello World'
            }
        },
        addTriggerToPanel: async (record: BaseRecord) => {
            return {
                ...record,
                trigger: "Added Trigger to Message"
            }
        },
        setAccess: async (record: BaseRecord) => {
            return {
                ...record,
                trigger: "Set Access to panel"
            }
        }
    }
}

export type DataProvider = typeof dataProvider & {
    message: {
        getHelloWorld: () => Promise<string>;
        addTriggerToBaseRecord: (record: BaseRecord) => Promise<BaseRecord>;
        setAccess: (record: BaseRecord) => Promise<BaseRecord>;
    },
    panel: {
        getHelloWorld: () => Promise<string>;
        addTriggerToBaseRecord: (record: BaseRecord) => Promise<BaseRecord>;
        setAccess: (record: BaseRecord) => Promise<BaseRecord>;
    }

}


export { dataProvider };

const nestCrudProvider = dataProviderNestjsxCrud(API_URL);
const dataProvider = {
    ...nestCrudProvider,
    message: {
        getHelloWorld: async () => {
            return {
                data: 'Hello World'
            }
        },
        addTriggerToMessage: async (record: BaseRecord) => {
            return {
                ...record,
                trigger: "Added Trigge to Message"
            }
        },
        setAccess: async (record: BaseRecord) => {
            return {
                ...record,
                trigger: "Set Access to Message"
            }
        }
    },
    panel: {
        getHelloWorld: async () => {
            return {
                data: 'Hello World'
            }
        },
        addTriggerToPanel: async (record: BaseRecord) => {
            return {
                ...record,
                trigger: "Added Trigger to Message"
            }
        },
        setAccess: async (record: BaseRecord) => {
            return {
                ...record,
                trigger: "Set Access to panel"
            }
        }
    }
}

export type DataProvider = typeof dataProvider & {
    message: {
        getHelloWorld: () => Promise<string>;
        addTriggerToBaseRecord: (record: BaseRecord) => Promise<BaseRecord>;
        setAccess: (record: BaseRecord) => Promise<BaseRecord>;
    },
    panel: {
        getHelloWorld: () => Promise<string>;
        addTriggerToBaseRecord: (record: BaseRecord) => Promise<BaseRecord>;
        setAccess: (record: BaseRecord) => Promise<BaseRecord>;
    }

}


export { dataProvider };

It has a few(and more coming) methods per resource(message and panel). We wanted to group them together like this for clarity.
We access each method like this-

  const {
    data: oneData,
    isLoading: oneIsLoading,
    refetch,
  } = useOne<{ data: string }, HttpError>({
    liveMode: "off",
    dataProviderName: "default",
    queryOptions: {
      queryFn: async () => {
        const response = await dataProvider.message.getHelloWorld();
        console.log(response);
        return { data: response.data }; // Ensure the data property is of type BaseRecord
      },
    },
  });

  const {
    data: oneData,
    isLoading: oneIsLoading,
    refetch,
  } = useOne<{ data: string }, HttpError>({
    liveMode: "off",
    dataProviderName: "default",
    queryOptions: {
      queryFn: async () => {
        const response = await dataProvider.message.getHelloWorld();
        console.log(response);
        return { data: response.data }; // Ensure the data property is of type BaseRecord
      },
    },
  });

Is this the best/prescribed way to get to methods in a provider that have been added to the default/required methods?

Hi @mjd. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To access custom methods on a dataProvider in refine, you can indeed use the approach you've described. However, refine provides a more integrated way to handle custom methods through the custom method in the dataProvider interface, which can be accessed using the useCustom hook. This approach is more aligned with refine's architecture and allows you to leverage refine's built-in features like caching, error handling, and more. Here's how you can define and use a custom method: 1. Define the custom method in your dataProvider: You can add a custom method to your dataProvider to handle requests with custom parameters. This is useful for non-standard REST API endpoints or external resources.

   const dataProvider = {
       ...nestCrudProvider,
       custom: async ({ url, method, payload }) => {
           // Handle the request according to your API requirements
           return {
               data: 'Custom response data'
           };
       },
       // other methods...
   };

   const dataProvider = {
       ...nestCrudProvider,
       custom: async ({ url, method, payload }) => {
           // Handle the request according to your API requirements
           return {
               data: 'Custom response data'
           };
       },
       // other methods...
   };

2. Use the useCustom hook to access the custom method: The useCustom hook allows you to call the custom method defined in your dataProvider.

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

   const { data, isLoading } = useCustom({
       url: "your-custom-endpoint",
       method: "get", // or "post", "put", etc.
       payload: {}, // any payload if needed
   });

   console.log(data);

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

   const { data, isLoading } = useCustom({
       url: "your-custom-endpoint",
       method: "get", // or "post", "put", etc.
       payload: {}, // any payload if needed
   });

   console.log(data);

This approach ensures that your custom methods are integrated into the refine ecosystem, allowing you to take advantage of refine's features. For more details, you can refer to the custom method documentation and the useCustom hook documentation. If you prefer to keep your current structure for clarity and organization, your approach is also valid, but using the custom method and useCustom hook is the recommended way to align with refine's architecture. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai We have multiple methods. The custom method seems to only allow for 1. We will have many more. And each is per resource name.

kapa.ai•5w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- If you have multiple custom methods and want to organize them per resource, you can still use the custom method approach by leveraging the meta parameter to differentiate between different operations. However, if you prefer to keep your current structure for clarity and organization, you can continue using your existing approach. Here's how you can use the meta parameter to handle multiple custom methods within the custom method: 1. Define the custom method with differentiation using meta: You can use the meta parameter to pass additional information that helps differentiate between different custom operations.

   const dataProvider = {
       ...nestCrudProvider,
       custom: async ({ url, method, meta, payload }) => {
           if (meta?.operation === "getHelloWorld") {
               return {
                   data: 'Hello World'
               };
           } else if (meta?.operation === "addTriggerToMessage") {
               return {
                   ...payload,
                   trigger: "Added Trigger to Message"
               };
           }
           // Add more operations as needed
           return { data: null };
       },
       // other methods...
   };

   const dataProvider = {
       ...nestCrudProvider,
       custom: async ({ url, method, meta, payload }) => {
           if (meta?.operation === "getHelloWorld") {
               return {
                   data: 'Hello World'
               };
           } else if (meta?.operation === "addTriggerToMessage") {
               return {
                   ...payload,
                   trigger: "Added Trigger to Message"
               };
           }
           // Add more operations as needed
           return { data: null };
       },
       // other methods...
   };

2. Use the useCustom hook with meta to specify the operation: When calling the custom method, specify the operation using the meta parameter.

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

   const { data, isLoading } = useCustom({
       url: "your-custom-endpoint",
       method: "post", // or "get", "put", etc.
       meta: { operation: "getHelloWorld" },
       payload: {}, // any payload if needed
   });

   console.log(data);

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

   const { data, isLoading } = useCustom({
       url: "your-custom-endpoint",
       method: "post", // or "get", "put", etc.
       meta: { operation: "getHelloWorld" },
       payload: {}, // any payload if needed
   });

   console.log(data);

This approach allows you to handle multiple custom methods within a single custom method by using the meta parameter to differentiate between them. However, if you find your current structure more intuitive and maintainable, you can continue using it as it aligns with your organizational needs. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Putting them all in a single method, than having to decide via the meta.operation value will be a maintenance nightmare. So we wont want to go down that path. Any other options?

kapa.ai•5w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Given your requirement to maintain clarity and organization by grouping methods per resource, and to avoid the complexity of handling multiple operations within a single custom method, your current approach of directly accessing custom methods on the dataProvider object is a valid and practical solution. This approach allows you to define and organize methods in a way that is clear and maintainable. Here's a recap of your approach, which is suitable for your needs: 1. Define Custom Methods in the dataProvider: You can define custom methods directly within the dataProvider object, organized by resource.

   const dataProvider = {
       ...nestCrudProvider,
       message: {
           getHelloWorld: async () => {
               return {
                   data: 'Hello World'
               };
           },
           addTriggerToMessage: async (record) => {
               return {
                   ...record,
                   trigger: "Added Trigger to Message"
               };
           },
           // More methods...
       },
       panel: {
           getHelloWorld: async () => {
               return {
                   data: 'Hello World'
               };
           },
           addTriggerToPanel: async (record) => {
               return {
                   ...record,
                   trigger: "Added Trigger to Panel"
               };
           },
           // More methods...
       }
   };

   const dataProvider = {
       ...nestCrudProvider,
       message: {
           getHelloWorld: async () => {
               return {
                   data: 'Hello World'
               };
           },
           addTriggerToMessage: async (record) => {
               return {
                   ...record,
                   trigger: "Added Trigger to Message"
               };
           },
           // More methods...
       },
       panel: {
           getHelloWorld: async () => {
               return {
                   data: 'Hello World'
               };
           },
           addTriggerToPanel: async (record) => {
               return {
                   ...record,
                   trigger: "Added Trigger to Panel"
               };
           },
           // More methods...
       }
   };

2. Access Custom Methods Directly: You can access these methods directly in your components, as you have been doing.

   const {
       data: oneData,
       isLoading: oneIsLoading,
       refetch,
   } = useOne({
       liveMode: "off",
       dataProviderName: "default",
       queryOptions: {
           queryFn: async () => {
               const response = await dataProvider.message.getHelloWorld();
               console.log(response);
               return { data: response.data };
           },
       },
   });

   const {
       data: oneData,
       isLoading: oneIsLoading,
       refetch,
   } = useOne({
       liveMode: "off",
       dataProviderName: "default",
       queryOptions: {
           queryFn: async () => {
               const response = await dataProvider.message.getHelloWorld();
               console.log(response);
               return { data: response.data };
           },
       },
   });

This approach keeps your code organized and allows you to easily add more methods as needed without complicating the dataProvider logic. It also aligns with your preference for clarity and maintainability. If you need further customization or integration with refine's features, you can explore refine's documentation for additional hooks and utilities that might fit your use case: refine documentation. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
