Answer a question

I am trying to upgrade to React Router v6 (react-router-dom 6.0.1).

Here is my updated code:

import { BrowserRouter, Navigate, Route, Routes } from 'react-router-dom';

<BrowserRouter>
  <Routes>
    <Route path="/" element={<Home />} />
    <Route path="/lab" element={<Lab />} />
    <Route render={() => <Navigate to="/" />} />
  </Routes>
</BrowserRouter>

The last Route is redirecting the rest of paths to /.

However, I got an error

TS2322: Type '{ render: () => Element; }' is not assignable to type 'IntrinsicAttributes & (PathRouteProps | LayoutRouteProps | IndexRouteProps)'.   Property 'render' does not exist on type 'IntrinsicAttributes & (PathRouteProps | LayoutRouteProps | IndexRouteProps)'.

However, based on the doc, it does have render for Route. How to use it correctly?

I think you should use the no match route approach.

Check this in the documentation.

https://reactrouter.com/docs/en/v6/getting-started/tutorial#adding-a-no-match-route

import { BrowserRouter, Navigate, Route, Routes } from 'react-router-dom';

<BrowserRouter>
  <Routes>
    <Route path="/" element={<Home />} />
    <Route path="/lab" element={<Lab />} />
    <Route
        path="*"
        element={<Navigate to="/" replace />}
    />
  </Routes>
</BrowserRouter>

To keep the history clean, you should set replace prop. This will avoid extra redirects after the user click back. Thanks @Paul for this tip.
