How Can I do code split in Refine

I want to do lazy load when user change route. ref: https://reactrouter.com/en/main/route/lazy check the picture #1 . And it said ⚠️ only work in data router . What is data router? ref: https://reactrouter.com/en/main/routers/picking-a-router#using-v64-data-apis check the picture #2 . Refine use BrowserRouter which is NOT data router. I've tried React.lazy to code split the pages, but it did NOT work. . Do anyone know how to do code split in Refine?

Hi @j7.dev. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

---------------------- Refine uses React Router v6, and you can implement lazy loading with route-based code-splitting. To do this, you can use React.lazy() and Suspense when defining your routes. Here's an example from the provided extracts:

import React, { Suspense, lazy } from "react";  
import { BrowserRouter as Router, Routes, Route } from "react-router-dom";  
  
const Home = React.lazy(() => import("./Home"));  
const About = React.lazy(() => import("./About"));  
  
const App = () => (  
 <Router>  
 <Suspense fallback={<div>Loading...</div>}>  
 <Routes>  
 <Route path="/" element={<Home />} />  
 <Route path="/about" element={<About />} />  
 </Routes>  
 </Suspense>  
 </Router>  
);

import React, { Suspense, lazy } from "react";  
import { BrowserRouter as Router, Routes, Route } from "react-router-dom";  
  
const Home = React.lazy(() => import("./Home"));  
const About = React.lazy(() => import("./About"));  
  
const App = () => (  
 <Router>  
 <Suspense fallback={<div>Loading...</div>}>  
 <Routes>  
 <Route path="/" element={<Home />} />  
 <Route path="/about" element={<About />} />  
 </Routes>  
 </Suspense>  
 </Router>  
);

In this example, the Home and About components are lazily loaded when their respective routes are navigated to. Make sure to wrap your Routes component with Suspense and provide a fallback component to display while the lazy-loaded components are being fetched.

Hey @j7.dev I don't think your question is about refine. Because refine doesn't care about router.
