Refine framework CORS settings

import { useEffect, useState } from 'react'; import './App.css'; function App() { const makeAPICall = async () => { try { const response = await fetch(' http://localhost:8080/' , {mode:'cors'}); const data = await response.json(); console.log({ data }) } catch (e) { console.log(e) } } useEffect(() => { makeAPICall(); }, []) return ( <div className="App"> <h1>React Cors Guide</h1> </div> ); } export default App; I didn't see this code block in my code, is that under refine dataprovider implementation?

Hi @zion_48046. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The code you provided is a simple React component making a fetch request to an API with CORS mode enabled. This is not directly related to the Refine framework's data provider implementation. In Refine, the data provider is responsible for making API calls. It's an abstraction that allows Refine to communicate with various APIs and databases. The data provider you use depends on the API you're working with. Refine provides some out-of-the-box data providers, but you can also create a custom one if your API has specific requirements. Here's an example of a data provider implementation in Refine:

import React from "react";
import { DataProvider } from "@refinedev/core";
export const dataProvider = (url: string): DataProvider => ({
    getOne: async ({ id, resource }) => {
        const response = await fetch(`${url}/${resource}/${id}`);
        const data = await response.json();
        return {
            data,
        };
    },
    // ... other methods like create, update, deleteOne, getList
    getApiUrl: () => url,
});

import React from "react";
import { DataProvider } from "@refinedev/core";
export const dataProvider = (url: string): DataProvider => ({
    getOne: async ({ id, resource }) => {
        const response = await fetch(`${url}/${resource}/${id}`);
        const data = await response.json();
        return {
            data,
        };
    },
    // ... other methods like create, update, deleteOne, getList
    getApiUrl: () => url,
});

(Source: refine.dev docs (https://refine.dev/docs/guides-concepts/data-fetching#multiple-data-providers)) In this example, the fetch API is used to make the HTTP requests. If you need to enable CORS for these requests, you can do so by adding the {mode:'cors'} option to the fetch calls, similar to your provided code. However, please note that CORS is a security feature implemented in browsers and configured on the server-side. If you're having CORS issues, you might need to adjust the server's CORS settings. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
