πŸ” Private Route in React Router v6

Things are changing fast in WEB today, and react-router v6 is in beta already and around the corner. πŸ€”

This is just for learning purposes only, react-router v6 is still in beta, use at your own risk

Private routes in v5 and below were done in a specific way using a custom component mostly named PrivateRoute that was most of the times just a wrapper and composition of basic Route and Redirect e.g.

function PrivateRoute(props) {
  let { component: Component, children, render, ...rest } = props
  let auth = useAuth();
  return (
    <Route
      {...rest}
      render={() => auth
        ? <Component />
        : <Redirect to="/login" />
      }
    />
  );
}

function App() {
  return (
    <BrowserRouter>
      <Route path="/" component={Public} />
      <PrivateRoute path="/private" component={Private} />
    </BrowserRouter>
  );
}
Enter fullscreen mode Exit fullscreen mode

But taking a look at v6 docs it seems that things changed a little bit, and we need to think a little bit different about it.

For info about all API reference see the link

Let's move on.

Some things that we used to create PrivateRoute have changed a little bit

  • Redirect is now Navigate
  • Route props changed and is just a stub component now
  • A new component Routes appearead

In v6, routes are rendered in such a manner

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/" element={<Public />} />
        <Route path="/private" element={<Private />} />
      </Routes>
    </BrowserRouter>
  );
}

const Public = () => <div>public</div>;
const Private = () => <div>private</div>;
Enter fullscreen mode Exit fullscreen mode

So as you can see, no more render props or component prop.
You need to pass a direct JSX element (don't worry about performance if you do)

Ok now let's take a look at Route component source code

/**
 * Declares an element that should be rendered at a certain URL path.
 *
 * @see https://reactrouter.com/api/Route
 */
export function Route(_props: RouteProps): React.ReactElement | null {
  invariant(
    false,
    `A <Route> is only ever to be used as the child of <Routes> element, ` +
      `never rendered directly. Please wrap your <Route> in a <Routes>.`
  );
}
Enter fullscreen mode Exit fullscreen mode

wait a minute

Wait a minute where is the code? πŸ‘€ Well actually the parent component Routes will use the Route just as a host for the props and children, and do nothing more with the Route

For more info about Routes implementation see link

So how we do implement our PrivateRoute now? πŸ€” If we do some adjustments to PrivateRoute props, it will look like this

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/" element={<Public />} />
        <PrivateRoute path="/private" element={<Private />} />
      </Routes>
    </BrowserRouter>
  );
}
Enter fullscreen mode Exit fullscreen mode

But this will not work. Routes will just take the props of PrivateRoute and ignore it's body totally. Even a console.log inside PrivateRoute will not be shown.

So what we do? πŸ€” We do some more adjustments to PrivateRoute

function PrivateRoute({ children }) {
  const auth = useAuth();
  return auth ? <>{children}</> : <Navigate to="/login" />;
}
Enter fullscreen mode Exit fullscreen mode

As you can see we changed Redirect to Navigate, and just return children if user is authenticated. And the usage of it also changes a little bit

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/" element={<Public />} />
        <Route
          path="/private"
          element={
            <PrivateRoute>
              <Private />
            </PrivateRoute>
          }
        />
      </Routes>
    </BrowserRouter>
  );
}
Enter fullscreen mode Exit fullscreen mode

As you can see PrivateRoute also moves to element prop.

The implementation of PrivateRoute can be done in multiple ways.

Here is a different implementation of PrivateRoute using Outlet

function PrivateOutlet() {
  const auth = useAuth();
  return auth ? <Outlet /> : <Navigate to="/login" />;
}

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/private-outlet" element={<PrivateOutlet />}>
          <Route element={<Private />} />
        </Route>
      </Routes>
    </BrowserRouter>
  );
}
Enter fullscreen mode Exit fullscreen mode

The pros of this is that you can put multiple private sub routes under same route.

That's all for today. Happy coding! πŸŽ‰ 🎊 ✨

Keep your users secure!

I was using a module to route users to I only need to render the header once etc.. so in I have outlet to render the nested routes. How can I now use the with the nested routes. This was my homeModule

return (<>
<Header selectedPage={0} />
<main className="w-main flex-1 shadow-md m-auto p-5 my-5 rounded-sm flex">
  <Outlet/>
</main>
</>);
Enter fullscreen mode Exit fullscreen mode

And this is how I would want to have it work:

<Route path="/" element={<PrivateOutlet />}>
  <Route exact path="/requests" element={<RequestsPage />} />
  ...
</Route>
Enter fullscreen mode Exit fullscreen mode

Whoops, I already figured it out, this was the code for my privateoutlet:

export default function PrivateOutlet() {
    const { account } = useContext(AccountContext);

    return account ? (
        <HomeModule>
            <Outlet />
        </HomeModule>
    ) : (
        <Navigate to="/login" replace />
    );
}
Enter fullscreen mode Exit fullscreen mode

Perfeito, muito obrigado (thank you)! But just aesthetic issues I recommend I created the component that manages private routes receiving props and your code is more reduced and clean.

Example

component={Page} should be capital C component or should at lease be defined:

const PrivateRoute = ({component: Component}) => {
Enter fullscreen mode Exit fullscreen mode

You could use auth-react-router package npmjs.com/package/auth-react-router

It provides a really simple API to define your routes and few more configurations (like redirect routes for authorized and unauthorized routes, fallback component for each of the routes)

Just define your routes path and pages component and it will work
