Hi @dreamer9067. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- You can extend the REST data provider and add your custom functions by overriding the methods of the data provider. The simplest way to do this is to use the Spread syntax. For example, if you want to override the update function of the @refinedev/simple-rest data provider, you can do it like this:
import dataProvider from "@refinedev/simple-rest";

const simpleRestProvider = dataProvider("API_URL");
const myDataProvider = {
...simpleRestProvider,
update: async ({ resource, id, variables }) => {
const url = `${apiUrl}/${resource}/${id}`;

const { data } = await httpClient.put(url, variables);

return {
data,
};
},
};

<Refine dataProvider={myDataProvider} />;
import dataProvider from "@refinedev/simple-rest";

const simpleRestProvider = dataProvider("API_URL");
const myDataProvider = {
...simpleRestProvider,
update: async ({ resource, id, variables }) => {
const url = `${apiUrl}/${resource}/${id}`;

const { data } = await httpClient.put(url, variables);

return {
data,
};
},
};

<Refine dataProvider={myDataProvider} />;
In this example, @refinedev/simple-rest uses the PATCH HTTP method for update, and it's changed to PUT without forking the whole data provider. You can also add a custom method to handle requests with custom parameters like URL, CRUD methods, and configurations. This is useful if you have non-standard REST API endpoints or want to make a connection with external resources. Here's an example:
custom: async ({
url,
method,
filters,
sorters,
payload,
query,
headers,
meta,
}) => {
// You can handle the request according to your API requirements.

return {
data,
};
};
custom: async ({
url,
method,
filters,
sorters,
payload,
query,
headers,
meta,
}) => {
// You can handle the request according to your API requirements.

return {
data,
};
};
Refine will consume this method using the useCustom data hook. For more detailed information, you can refer to the Refine documentation (https://refine.dev/docs/api-reference/core/providers/data-provider). If you need to customize the data provider to work with a REST API that doesn't follow the simple-rest design, you can use the swizzle command to customize the data provider. You can find more information about this in the Refine documentation (https://refine.dev/docs/packages/documentation/data-providers/simple-rest). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

what is the preferred way to make use of custom non-rest json api? I'm not fan of using custom method from IDataContextProvider because it's not typesafe. Let's imagine that I have Users resource that have also users/{id}/ban method. I would like to have custom, typesafe ban method. I can't easily do this inside my own DataProvider, because useDataProvider hook always returns IDataContextProvider and my method won't be visible. Is there possibility to somehow safely cast it to my own provider? Maybe something like useDataProvider<MyUsersDataProvider>()
