Patch Changes

6.21.1

Patch Changes

6.21.0

Minor Changes

  • Add a new future.v7_relativeSplatPath flag to implement a breaking bug fix to relative routing when inside a splat route. (#11087)

    This fix was originally added in #10983 and was later reverted in #11078 because it was determined that a large number of existing applications were relying on the buggy behavior (see #11052)

    The Bug The buggy behavior is that without this flag, the default behavior when resolving relative paths is to ignore any splat (*) portion of the current route path.

    The Background This decision was originally made thinking that it would make the concept of nested different sections of your apps in <Routes> easier if relative routing would replace the current splat:

    <BrowserRouter>
  <Routes>
    <Route path="/" element={<Home />} />
    <Route path="dashboard/*" element={<Dashboard />} />
  </Routes>
</BrowserRouter>

    Any paths like /dashboard, /dashboard/team, /dashboard/projects will match the Dashboard route. The dashboard component itself can then render nested <Routes>:

    function Dashboard() {
  return (
    <div>
      <h2>Dashboard</h2>
      <nav>
        <Link to="/">Dashboard Home</Link>
        <Link to="team">Team</Link>
        <Link to="projects">Projects</Link>
      </nav>

      <Routes>
        <Route path="/" element={<DashboardHome />} />
        <Route path="team" element={<DashboardTeam />} />
        <Route path="projects" element={<DashboardProjects />} />
      </Routes>
    </div>
  );
}

    Now, all links and route paths are relative to the router above them. This makes code splitting and compartmentalizing your app really easy. You could render the Dashboard as its own independent app, or embed it into your large app without making any changes to it.

    The Problem

    The problem is that this concept of ignoring part of a path breaks a lot of other assumptions in React Router - namely that "." always means the current location pathname for that route. When we ignore the splat portion, we start getting invalid paths when using ".":

    // If we are on URL /dashboard/team, and we want to link to /dashboard/team:
function DashboardTeam() {
  // ❌ This is broken and results in <a href="/dashboard">
  return <Link to=".">A broken link to the Current URL</Link>;

  // ✅ This is fixed but super unintuitive since we're already at /dashboard/team!
  return <Link to="./team">A broken link to the Current URL</Link>;
}

    We've also introduced an issue that we can no longer move our DashboardTeam component around our route hierarchy easily - since it behaves differently if we're underneath a non-splat route, such as /dashboard/:widget. Now, our "." links will, properly point to ourself inclusive of the dynamic param value so behavior will break from it's corresponding usage in a /dashboard/* route.

    Even worse, consider a nested splat route configuration:

    <BrowserRouter>
  <Routes>
    <Route path="dashboard">
      <Route path="*" element={<Dashboard />} />
    </Route>
  </Routes>
</BrowserRouter>

    Now, a <Link to="."> and a <Link to=".."> inside the Dashboard component go to the same place! That is definitely not correct!

    Another common issue arose in Data Routers (and Remix) where any <Form> should post to it's own route action if you the user doesn't specify a form action:

    let router = createBrowserRouter({
  path: "/dashboard",
  children: [
    {
      path: "*",
      action: dashboardAction,
      Component() {
        // ❌ This form is broken!  It throws a 405 error when it submits because
        // it tries to submit to /dashboard (without the splat value) and the parent
        // `/dashboard` route doesn't have an action
        return <Form method="post">...</Form>;
      },
    },
  ],
});

    This is just a compounded issue from the above because the default location for a Form to submit to is itself (".") - and if we ignore the splat portion, that now resolves to the parent route.

    The Solution If you are leveraging this behavior, it's recommended to enable the future flag, move your splat to it's own route, and leverage ../ for any links to "sibling" pages:

    <BrowserRouter>
  <Routes>
    <Route path="dashboard">
      <Route index path="*" element={<Dashboard />} />
    </Route>
  </Routes>
</BrowserRouter>

function Dashboard() {
  return (
    <div>
      <h2>Dashboard</h2>
      <nav>
        <Link to="..">Dashboard Home</Link>
        <Link to="../team">Team</Link>
        <Link to="../projects">Projects</Link>
      </nav>

      <Routes>
        <Route path="/" element={<DashboardHome />} />
        <Route path="team" element={<DashboardTeam />} />
        <Route path="projects" element={<DashboardProjects />} />
      </Router>
    </div>
  );
}

    This way, . means "the full current pathname for my route" in all cases (including static, dynamic, and splat routes) and .. always means "my parents pathname".

Patch Changes

6.20.1

Patch Changes

6.20.0

Minor Changes

  • Export the PathParam type from the public API (#10719)

Patch Changes

6.19.0

Minor Changes

  • Add unstable_flushSync option to useNavigate/useSumbit/fetcher.load/fetcher.submit to opt-out of React.startTransition and into ReactDOM.flushSync for state updates (#11005)
  • Allow unstable_usePrompt to accept a BlockerFunction in addition to a boolean (#10991)

Patch Changes

  • Fix issue where a changing fetcher key in a useFetcher that remains mounted wasn't getting picked up (#11009)
  • Fix useFormAction which was incorrectly inheriting the ?index query param from child route action submissions (#11025)
  • Fix NavLink active logic when to location has a trailing slash (#10734)
  • Updated dependencies:

6.18.0

Minor Changes

  • Add support for manual fetcher key specification via useFetcher({ key: string }) so you can access the same fetcher instance from different components in your application without prop-drilling (RFC) (#10960)

    • Fetcher keys are now also exposed on the fetchers returned from useFetchers so that they can be looked up by key

  • Add navigate/fetcherKey params/props to useSumbit/Form to support kicking off a fetcher submission under the hood with an optionally user-specified key (#10960)

    • Invoking a fetcher in this way is ephemeral and stateless
    • If you need to access the state of one of these fetchers, you will need to leverage useFetcher({ key }) to look it up elsewhere

Patch Changes

  • Adds a fetcher context to RouterProvider that holds completed fetcher data, in preparation for the upcoming future flag that will change the fetcher persistence/cleanup behavior (#10961)
  • Fix the future prop on BrowserRouter, HashRouter and MemoryRouter so that it accepts a Partial<FutureConfig> instead of requiring all flags to be included. (#10962)
  • Updated dependencies:

6.17.0

Minor Changes

  • 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:

    function ImageLink(to, src, alt) {
  let isTransitioning = unstable_useViewTransitionState(to);
  return (
    <Link to={to} unstable_viewTransition>
      <img
        src={src}
        alt={alt}
        style={{
          viewTransitionName: isTransitioning ? "image-expand" : "",
        }}
      />
    </Link>
  );
}

    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:

    a.transitioning img {
  view-transition-name: "image-expand";
}
    <NavLink to={to} unstable_viewTransition>
  <img src={src} alt={alt} />
</NavLink>

    For an example usage of View Transitions with React Router, check out our fork of the Astro Records demo.

    For more information on using the View Transitions API, please refer to the Smooth and simple transitions with the View Transitions API guide from the Google Chrome team.

    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

Minor Changes

Patch Changes

  • Properly encode rendered URIs in server rendering to avoid hydration errors (#10769)

6.15.0

Minor Changes

Patch Changes

  • Fixes an edge-case affecting web extensions in Firefox that use URLSearchParams and the useSearchParams hook. (#10620)
  • Do not include hash in useFormAction() for unspecified actions since it cannot be determined on the server and causes hydration issues (#10758)
  • Reorder effects in unstable_usePrompt to avoid throwing an exception if the prompt is unblocked and a navigation is performed synchronously (#10687, #10718)
  • Updated dependencies:

6.14.2

Patch Changes

  • Properly decode element id when emulating hash scrolling via <ScrollRestoration> (#10682)
  • Add missing <Form state> prop to populate history.state on submission navigations (#10630)

  • Updated dependencies:

6.14.1

Patch Changes

6.14.0

Minor Changes

  • Add support for application/json and text/plain encodings for useSubmit/fetcher.submit. To reflect these additional types, useNavigation/useFetcher now also contain navigation.json/navigation.text and fetcher.json/fetcher.text which include the json/text submission if applicable (#10413)

    // The default behavior will still serialize as FormData
function Component() {
  let navigation = useNavigation();
  let submit = useSubmit();
  submit({ key: "value" }, { method: "post" });
  // navigation.formEncType => "application/x-www-form-urlencoded"
  // navigation.formData    => FormData instance
}

async function action({ request }) {
  // request.headers.get("Content-Type") => "application/x-www-form-urlencoded"
  // await request.formData()            => FormData instance
}
    // Opt-into JSON encoding with `encType: "application/json"`
function Component() {
  let navigation = useNavigation();
  let submit = useSubmit();
  submit({ key: "value" }, { method: "post", encType: "application/json" });
  // navigation.formEncType => "application/json"
  // navigation.json        => { key: "value" }
}

async function action({ request }) {
  // request.headers.get("Content-Type") => "application/json"
  // await request.json()                => { key: "value" }
}
    // Opt-into text encoding with `encType: "text/plain"`
function Component() {
  let navigation = useNavigation();
  let submit = useSubmit();
  submit("Text submission", { method: "post", encType: "text/plain" });
  // navigation.formEncType => "text/plain"
  // navigation.text        => "Text submission"
}

async function action({ request }) {
  // request.headers.get("Content-Type") => "text/plain"
  // await request.text()                => "Text submission"
}

Patch Changes

  • When submitting a form from a submitter element, prefer the built-in new FormData(form, submitter) instead of the previous manual approach in modern browsers (those that support the new submitter parameter) (#9865, #10627)
    • For browsers that don't support it, we continue to just append the submit button's entry to the end, and we also add rudimentary support for type="image" buttons
    • If developers want full spec-compliant support for legacy browsers, they can use the formdata-submitter-polyfill
  • Call window.history.pushState/replaceState before updating React Router state (instead of after) so that window.location matches useLocation during synchronous React 17 rendering (#10448)
    • ⚠️ However, generally apps should not be relying on window.location and should always reference useLocation when possible, as window.location will not be in sync 100% of the time (due to popstate events, concurrent mode, etc.)
  • Fix tsc --skipLibCheck:false issues on React 17 (#10622)
  • Upgrade typescript to 5.1 (#10581)
  • Updated dependencies:

6.13.0

Minor Changes

  • Move React.startTransition usage behind a future flag to avoid issues with existing incompatible Suspense usages. We recommend folks adopting this flag to be better compatible with React concurrent mode, but if you run into issues you can continue without the use of startTransition until v7. Issues usually boils down to creating net-new promises during the render cycle, so if you run into issues you should either lift your promise creation out of the render cycle or put it behind a useMemo. (#10596)

    Existing behavior will no longer include React.startTransition:

    <BrowserRouter>
  <Routes>{/*...*/}</Routes>
</BrowserRouter>

<RouterProvider router={router} />

    If you wish to enable React.startTransition, pass the future flag to your component:

    <BrowserRouter future={{ v7_startTransition: true }}>
  <Routes>{/*...*/}</Routes>
</BrowserRouter>

<RouterProvider router={router} future={{ v7_startTransition: true }}/>

Patch Changes

  • Work around webpack/terser React.startTransition minification bug in production mode (#10588)
  • Updated dependencies:

6.12.1

Warning

Please use version 6.13.0 or later instead of 6.12.1. This version suffers from a webpack/terser minification issue resulting in invalid minified code in your resulting production bundles which can cause issues in your application. See #10579 for more details.

Patch Changes

  • Adjust feature detection of React.startTransition to fix webpack + react 17 compilation error (#10569)
  • Updated dependencies:

6.12.0

Minor Changes

  • Wrap internal router state updates with React.startTransition if it exists (#10438)

Patch Changes

6.11.2

Patch Changes

6.11.1

Patch Changes

6.11.0

Minor Changes

  • Enable basename support in useFetcher (#10336)
    • If you were previously working around this issue by manually prepending the basename then you will need to remove the manually prepended basename from your fetcher calls (fetcher.load('/basename/route') -> fetcher.load('/route'))

Patch Changes

  • Fix inadvertent re-renders when using Component instead of element on a route definition (#10287)
  • Fail gracefully on <Link to="//"> and other invalid URL values (#10367)
  • Switched from useSyncExternalStore to useState for internal @remix-run/router router state syncing in <RouterProvider>. We found some subtle bugs where router state updates got propagated before other normal useState updates, which could lead to footguns in useEffect calls. (#10377, #10409)
  • Add static prop to StaticRouterProvider's internal Router component (#10401)
  • When using a RouterProvider, useNavigate/useSubmit/fetcher.submit are now stable across location changes, since we can handle relative routing via the @remix-run/router instance and get rid of our dependence on useLocation(). When using BrowserRouter, these hooks remain unstable across location changes because they still rely on useLocation(). (#10336)
  • Updated dependencies:

6.10.0

Minor Changes

  • Added support for Future Flags in React Router. The first flag being introduced is future.v7_normalizeFormMethod which will normalize the exposed useNavigation()/useFetcher() formMethod fields as uppercase HTTP methods to align with the fetch() behavior. (#10207)

    • When future.v7_normalizeFormMethod === false (default v6 behavior),
      • useNavigation().formMethod is lowercase
      • useFetcher().formMethod is lowercase
    • When future.v7_normalizeFormMethod === true:
      • useNavigation().formMethod is uppercase
      • useFetcher().formMethod is uppercase

Patch Changes

6.9.0

Minor Changes

  • React Router now supports an alternative way to define your route element and errorElement fields as React Components instead of React Elements. You can instead pass a React Component to the new Component and ErrorBoundary fields if you choose. There is no functional difference between the two, so use whichever approach you prefer 😀. You shouldn't be defining both, but if you do Component/ErrorBoundary will "win". (#10045)

    Example JSON Syntax

    // Both of these work the same:
const elementRoutes = [{
  path: '/',
  element: <Home />,
  errorElement: <HomeError />,
}]

const componentRoutes = [{
  path: '/',
  Component: Home,
  ErrorBoundary: HomeError,
}]

function Home() { ... }
function HomeError() { ... }

    Example JSX Syntax

    // Both of these work the same:
const elementRoutes = createRoutesFromElements(
  <Route path='/' element={<Home />} errorElement={<HomeError /> } />
);

const componentRoutes = createRoutesFromElements(
  <Route path='/' Component={Home} ErrorBoundary={HomeError} />
);

function Home() { ... }
function HomeError() { ... }

  • Introducing Lazy Route Modules! (#10045)

    In order to keep your application bundles small and support code-splitting of your routes, we've introduced a new lazy() route property. This is an async function that resolves the non-route-matching portions of your route definition (loader, action, element/Component, errorElement/ErrorBoundary, shouldRevalidate, handle).

    Lazy routes are resolved on initial load and during the loading or submitting phase of a navigation or fetcher call. You cannot lazily define route-matching properties (path, index, children) since we only execute your lazy route functions after we've matched known routes.

    Your lazy functions will typically return the result of a dynamic import.

    // In this example, we assume most folks land on the homepage so we include that
// in our critical-path bundle, but then we lazily load modules for /a and /b so
// they don't load until the user navigates to those routes
let routes = createRoutesFromElements(
  <Route path="/" element={<Layout />}>
    <Route index element={<Home />} />
    <Route path="a" lazy={() => import("./a")} />
    <Route path="b" lazy={() => import("./b")} />
  </Route>
);

    Then in your lazy route modules, export the properties you want defined for the route:

    export async function loader({ request }) {
  let data = await fetchData(request);
  return json(data);
}

// Export a `Component` directly instead of needing to create a React Element from it
export function Component() {
  let data = useLoaderData();

  return (
    <>
      <h1>You made it!</h1>
      <p>{data}</p>
    </>
  );
}

// Export an `ErrorBoundary` directly instead of needing to create a React Element from it
export function ErrorBoundary() {
  let error = useRouteError();
  return isRouteErrorResponse(error) ? (
    <h1>
      {error.status} {error.statusText}
    </h1>
  ) : (
    <h1>{error.message || error}</h1>
  );
}

    An example of this in action can be found in the examples/lazy-loading-router-provider directory of the repository.

    🙌 Huge thanks to @rossipedia for the Initial Proposal and POC Implementation.

Whoa this is a big one! 6.4.0 brings all the data loading and mutation APIs over from Remix. Here's a quick high level overview, but it's recommended you go check out the docs, especially the feature overview and the tutorial.

New APIs

  • Create your router with createMemoryRouter/createBrowserRouter/createHashRouter
  • Render your router with <RouterProvider>
  • Load data with a Route loader and mutate with a Route action
  • Handle errors with Route errorElement
  • Submit data with the new <Form> component
  • Perform in-page data loads and mutations with useFetcher()
  • Defer non-critical data with defer and Await
  • Manage scroll position with <ScrollRestoration>

New Features

  • Perform path-relative navigations with <Link relative="path"> (#9160)

Bug Fixes

  • Path resolution is now trailing slash agnostic (#8861)
  • useLocation returns the scoped location inside a <Routes location> component (#9094)
  • respect the <Link replace> prop if it is defined (#8779)
