Hi @Sly. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Fetching data from a website can be done in various ways depending on the technology you're using. In the context of Refine, a React-based framework, you would typically use a data provider to fetch data from your API. A data provider is a function that implements the DataProvider interface. It is responsible for communicating with your API and making data available to Refine applications. Refine passes relevant parameters like resource name, or the id of the record to your data provider, so data provider can make API calls to appropriate endpoints. Here's an example of how you might set up a data provider in Refine:

import React from "react";
import { DataProvider } from "@refinedev/core";

export const dataProvider = (url: string): DataProvider => ({
    getList: async ({ resource }) => {
        const response = await fetch(`${url}/${resource}`);
        const data = await response.json();
        return {
            data,
            total: data.length,
        };
    },
    getOne: async () => {
        throw new Error("Not implemented");
    },
    // ... other methods
    getApiUrl: () => url,
});

import React from "react";
import { DataProvider } from "@refinedev/core";

export const dataProvider = (url: string): DataProvider => ({
    getList: async ({ resource }) => {
        const response = await fetch(`${url}/${resource}`);
        const data = await response.json();
        return {
            data,
            total: data.length,
        };
    },
    getOne: async () => {
        throw new Error("Not implemented");
    },
    // ... other methods
    getApiUrl: () => url,
});

In this example, the getList method fetches a list of records from a specified resource. Other methods like getOne, getMany, create, update, and deleteOne can be implemented as needed. Once you've set up your data provider, you can use Refine's data hooks (useOne, useList, useUpdate, etc.) to manage your data. For example, to fetch a single record with the ID 123 from the products endpoint, you would use the useOne hook:

import React from "react";
import { useOne, BaseKey } from "@refinedev/core";

export const Product: React.FC = () => {
    const { data, error, isError, isLoading } = useOne<IProduct>({
        resource: "products",
        id: 123,
    });
// ... handle loading and error states

    const product = data?.data;

    return (
        <div>
            <h4>{product?.name}</h4>
            <p>Material: {product?.material}</p>
            <p>Price {product?.price}</p>
        </div>
    );
};

import React from "react";
import { useOne, BaseKey } from "@refinedev/core";

export const Product: React.FC = () => {
    const { data, error, isError, isLoading } = useOne<IProduct>({
        resource: "products",
        id: 123,
    });
// ... handle loading and error states

    const product = data?.data;

    return (
        <div>
            <h4>{product?.name}</h4>
            <p>Material: {product?.material}</p>
            <p>Price {product?.price}</p>
        </div>
    );
};

In this example, useOne fetches a single record from the products resource with the ID 123. For more information, you can refer to the Refine documentation on data fetching (https://refine.dev/docs/guides-concepts/data-fetching). Please note that this approach is specific to Refine and may not apply if you're using a different technology or framework. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
