v6.4.4

What's Changed

• 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)
• Support basename in static data routers (#9591)
• Enhanced ErrorResponse bodies to contain more descriptive text in internal 403/404/405 scenarios
• Fix issues with encoded characters in NavLink and descendant <Routes> (#9589, #9647)
• Properly serialize/deserialize ErrorResponse instances when using built-in hydration (#9593)
• Support basename in static data routers (#9591)
• Updated dependencies:

Patch Changes

• fix: remove internal router singleton (#9227)

  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,
