Property 'exact' does not exist on type

Question

I am trying to use react-router-dom inside my react app and also I am using typescript instead of javascript. The issue here is that I can't import Route inside my component and make it work. I already installed @types/react-router-dom but for some reason it's still not working as expected.

This is a component that is trying to use react-router-dom

import {BrowserRouter as Router, Route} from "react-router-dom";

const App = () => {
    return (
        <div>
            <Router>
                <div>
                    <Route path="/" exact/>
                </div>
            </Router>
        </div>
    )
}

export default App;

And this is the error that I am getting

TypeScript error in /Users/veselinkontic/Projects/givellet/frontend/src/components/index.tsx(9,37):
Type '{ path: string; exact: true; }' is not assignable to type 'IntrinsicAttributes & (PathRouteProps | LayoutRouteProps | IndexRouteProps)'.
  Property 'exact' does not exist on type 'IntrinsicAttributes & (PathRouteProps | LayoutRouteProps | IndexRouteProps)'.  TS2322

     7 |             <Router>
     8 |                 <div>
  >  9 |                     <Route path="/" exact/>
       |                                     ^
    10 |                 </div>
    11 |             </Router>
    12 |         </div>

And this is my package.json file in which you can see that everything is there.

Answer 1

react router v6 doesn't support exact anymore.

// old - v5 <Route exact path="/" component={Home} />

// new - v6 <Route path="/" element={<Home />} />

As stated in their documentation:

You don't need to use an exact prop on <Route path="/"> anymore. This is because all paths match exactly by default. If you want to match more of the URL because you have child routes use a trailing * as in <Route path="users/*">.

You can refer to this migration guide: https://reactrouter.com/docs/en/v6/upgrading/v5

Answer 2

I have been through this same issue, the new React-Router doesn't support the exact keyword. You can simply remove it from the <Route .../> and it will work just fine.

Also instead of component you have to use element and pass the element tag into it.

Answer 3

In the case of React Router v6, I add Routes and Route to the import.

Example:

import { BrowserRouter, Route, Routes  } from 'react-router-dom';
import  Home  from "./pages/Home";
import  NewRoom  from "./pages/NewRoom";
    
function App() {
  return (
  <BrowserRouter>
      <Routes>
      <Route path="/"  element={<Home />}/>
      <Route path="/rooms/new" element={<NewRoom />}/>
      </Routes>
  </BrowserRouter>
  );
}
    
export default App;
