Throw an error if an action/loader function returns undefined as revalidations need to know whether the loader has previously been executed. undefined also causes issues during SSR stringification for hydration. You should always ensure your loader/action returns a value, and you may return null if you don't wish to return anything. (#9511)
Properly handle redirects to external domains (#9590, #9654)
Preserve the HTTP method on 307/308 redirects (#9597)
This change removes the internal module-level routerSingleton we create and maintain inside our data routers since it was causing a number of headaches for non-simple use cases:
Unit tests are a pain because you need to find a way to reset the singleton in-between tests
Use use a _resetModuleScope singleton for our tests
...but this isn't exposed to users who may want to do their own tests around our router
The JSX children <Route> objects cause non-intuitive behavior based on idiomatic react expectations
Conditional runtime <Route>'s won't get picked up
Adding new <Route>'s during local dev won't get picked up during HMR
Using external state in your elements doesn't work as one might expect (see #9225)
Instead, we are going to lift the singleton out into user-land, so that they create the router singleton and manage it outside the react tree - which is what react 18 is encouraging with useSyncExternalStore anyways! This also means that since users create the router - there's no longer any difference in the rendering aspect for memory/browser/hash routers (which only impacts router/history creation) - so we can get rid of those and trim to a simple RouterProvider
// Before
function App() {
<DataBrowserRouter>
<Route path="/" element={<Layout />}>
<Route index element={<Home />}>
</Route>
<DataBrowserRouter>
}
// After
let router = createBrowserRouter([{
path: "/",
element: <Layout />,
children: [{
index: true,
Add experimental support for the View Transitions API via document.startViewTransition to enable CSS animated transitions on SPA navigations in your application. (#10916)
The simplest approach to enabling a View Transition in your React Router app is via the new <Link unstable_viewTransition> prop. This will cause the navigation DOM update to be wrapped in document.startViewTransition which will enable transitions for the DOM update. Without any additional CSS styles, you'll get a basic cross-fade animation for your page.
If you need to apply more fine-grained styles for your animations, you can leverage the unstable_useViewTransitionState hook which will tell you when a transition is in progress and you can use that to apply classes or styles:
You can also use the <NavLink unstable_viewTransition> shorthand which will manage the hook usage for you and automatically add a transitioning class to the <a> during the transition:
Please note, that because the ViewTransition API is a DOM API, we now export a specific RouterProvider from react-router-dom with this functionality. If you are importing RouterProvider from react-router, then it will not support view transitions. (#10928
