[!WARNING] Please use version 6.20.1 or later instead of 6.20.0. We discovered that a large number of apps were relying on buggy behavior that was fixed in this release (#11045). We reverted the fix in 6.20.1 and will be re-introducing it behind a future flag in a subsequent release. See #11052 for more details.

Minor Changes

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

Patch Changes

• Do not revalidate unmounted fetchers when v7_fetcherPersist is enabled (#11044)
• Fix bug with resolveTo path resolution in splat routes (#11045)
  • This is a follow up to #10983 to handle the few other code paths using getPathContributingMatches
  • This removes the UNSAFE_getPathContributingMatches export from @remix-run/router since we no longer need this in the react-router/react-router-dom layers

What's Changed

unstable_flushSync API

This release brings a new unstable_flushSync option to the imperative APIs (useSubmit, useNavigate, fetcher.submit, fetcher.load) to let users opt-into synchronous DOM updates for pending/optimistic UI.

function handleClick() {
  submit(data, { flushSync: true });
  // Everything is flushed to the DOM so you can focus/scroll to your pending/optimistic UI
  setFocusAndOrScrollToNewlyAddedThing();
}

Minor Changes

• Add unstable_flushSync option to useNavigate/useSubmit/fetcher.load/fetcher.submit to opt-out of React.startTransition and into ReactDOM.flushSync for state updates (#11005)
• Remove the unstable_ prefix from the useBlocker hook as it's been in use for enough time that we are confident in the API (#10991)
  • We do not plan to remove the prefix from unstable_usePrompt due to differences in how browsers handle window.confirm that prevent React Router from guaranteeing consistent/correct behavior

Patch Changes

• Fix useActionData so it returns proper contextual action data and not any action data in the tree (#11023)

• Fix bug in useResolvedPath that would cause useResolvedPath(".") in a splat route to lose the splat portion of the URL path. (#10983)

  • ⚠️ This fixes a quite long-standing bug specifically for "." paths inside a splat route which incorrectly dropped the splat portion of the URL. If you are relative routing via "." inside a splat route in your application you should double check that your logic is not relying on this buggy behavior and update accordingly.

• 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)

• Fix types so unstable_usePrompt can accept a BlockerFunction in addition to a boolean (#10991)

• Fix relative="path" bug where relative path calculations started from the full location pathname, instead of from the current contextual route pathname. (#11006)

  <Route path="/a">
    <Route path="/b" element={<Component />}>
      <Route path="/c" />
    </Route>
  </Route>;
  
  function Component() {
    return (
      <>
        {/* This is now correctly relative to /a/b, not /a/b/c */}
        <Link to=".." relative="path" />
        <Outlet />
      </>
    );
  }

What's Changed

New Fetcher APIs

Per this RFC, we've introduced some new APIs that give you more granular control over your fetcher behaviors.

• You may now specify your own fetcher identifier via useFetcher({ key: string }), which allows you to access the same fetcher instance from different components in your application without prop-drilling
• Fetcher keys are now exposed on the fetchers returned from useFetchers so that they can be looked up by key
• Form and useSubmit now support optional navigate/fetcherKey props/params to allow kicking off a fetcher submission under the hood with an optionally user-specified key
  • <Form method="post" navigate={false} fetcherKey="my-key">
  • submit(data, { method: "post", navigate: false, fetcherKey: "my-key" })
  • 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 useFetchers() or useFetcher({ key }) to look it up elsewhere

Persistence Future Flag (future.v7_fetcherPersist)

Per the same RFC as above, we've introduced a new future.v7_fetcherPersist flag that allows you to opt-into the new fetcher persistence/cleanup behavior. Instead of being immediately cleaned up on unmount, fetchers will persist until they return to an idle state. This makes pending/optimistic UI much easier in scenarios where the originating fetcher needs to unmount.

• This is sort of a long-standing bug fix as the useFetchers() API was always supposed to only reflect in-flight fetcher information for pending/optimistic UI -- it was not intended to reflect fetcher data or hang onto fetchers after they returned to an idle state
• Keep an eye out for the following specific behavioral changes when opting into this flag and check your app for compatibility:
  • Fetchers that complete while still mounted will no longer appear in useFetchers() after completion - they served no purpose in there since you can access the data via useFetcher().data
  • Fetchers that previously unmounted while in-flight will not be immediately aborted and will instead be cleaned up once they return to an idle state
    • They will remain exposed via useFetchers while in-flight so you can still access pending/optimistic data after unmount
    • If a fetcher is no longer mounted when it completes, then it's result will not be post processed - e.g., redirects will not be followed and errors will not bubble up in the UI
    • However, if a fetcher was re-mounted elsewhere in the tree using the same key, then it's result will be processed, even if the originating fetcher was unmounted

Minor Changes

• Add fetcher key APIs and navigate=false options (#10960)
• Add future.v7_fetcherPersist flag (#10962)
• Add support for optional path segments in matchPath (#10768)

Patch Changes

• 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)
• Fix router.getFetcher/router.deleteFetcher type definitions which incorrectly specified key as an optional parameter (#10960)

What's Changed

View Transitions 🚀

We're excited to release experimental support for the View Transitions API in React Router! You can now trigger navigational DOM updates to be wrapped in document.startViewTransition to enable CSS animated transitions on SPA navigations in your application.

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) {
  const 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, check out our fork of the awesome 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.

Minor Changes

• Add support for view transitions (#10916)

Patch Changes

• Log a warning and fail gracefully in ScrollRestoration when sessionStorage is unavailable (#10848)
• Fix RouterProvider future prop type to be a Partial<FutureConfig> so that not all flags must be specified (#10900)
• Allow 404 detection to leverage root route error boundary if path contains a URL segment (#10852)
• Fix ErrorResponse type to avoid leaking internal field (#10876)

Full Changelog: 6.16.0...6.17.0

Date: 2023-09-13

Minor Changes

• In order to move towards stricter TypeScript support in the future, we're aiming to replace current usages of any with unknown on exposed typings for user-provided data. To do this in Remix v2 without introducing breaking changes in React Router v6, we have added generics to a number of shared types. These continue to default to any in React Router and are overridden with unknown in Remix. In React Router v7 we plan to move these to unknown as a breaking change. (#10843)
  • Location now accepts a generic for the location.state value
  • ActionFunctionArgs/ActionFunction/LoaderFunctionArgs/LoaderFunction now accept a generic for the context parameter (only used in SSR usages via createStaticHandler)
  • The return type of useMatches (now exported as UIMatch) accepts generics for match.data and match.handle - both of which were already set to unknown
• Move the @private class export ErrorResponse to an UNSAFE_ErrorResponseImpl export since it is an implementation detail and there should be no construction of ErrorResponse instances in userland. This frees us up to export a type ErrorResponse which correlates to an instance of the class via InstanceType. Userland code should only ever be using ErrorResponse as a type and should be type-narrowing via isRouteErrorResponse. (#10811)
• Export ShouldRevalidateFunctionArgs interface (#10797)
• Removed private/internal APIs only required for the Remix v1 backwards compatibility layer and no longer needed in Remix v2 (_isFetchActionRedirect, _hasFetcherDoneAnything) (#10715)

Patch Changes

• Properly encode rendered URIs in server rendering to avoid hydration errors (#10769)
• Add method/url to error message on aborted query/queryRoute calls (#10793)
• Fix a race-condition with loader/action-thrown errors on route.lazy routes (#10778)
• Fix type for actionResult on the arguments object passed to shouldRevalidate (#10779)

Full Changelog: v6.15.0...v6.16.0

Date: 2023-08-10

Minor Changes

• Add's a new redirectDocument() function which allows users to specify that a redirect from a loader/action should trigger a document reload (via window.location) instead of attempting to navigate to the redirected location via React Router (#10705)

Patch Changes

• Ensure useRevalidator is referentially stable across re-renders if revalidations are not actively occurring (#10707)
• Ensure hash history always includes a leading slash on hash pathnames (#10753)
• Fixes an edge-case affecting web extensions in Firefox that use URLSearchParams and the useSearchParams hook (#10620)
• Reorder effects in unstable_usePrompt to avoid throwing an exception if the prompt is unblocked and a navigation is performed synchronously (#10687, #10718)
• SSR: Do not include hash in useFormAction() for unspecified actions since it cannot be determined on the server and causes hydration issues (#10758)
• SSR: Fix an issue in queryRoute that was not always identifying thrown Response instances (#10717)
• react-router-native: Update @ungap/url-search-params dependency from ^0.1.4 to ^0.2.2 (#10590)

Full Changelog: v6.14.2...v6.15.0

Date: 2023-07-17

Patch Changes

• Add missing <Form state> prop to populate history.state on submission navigations (#10630)
• Trigger an error if a defer promise resolves/rejects with undefined in order to match the behavior of loaders and actions which must return a value or null (#10690)
• Properly handle fetcher redirects interrupted by normal navigations (#10674)
• Initial-load fetchers should not automatically revalidate on GET navigations (#10688)
• Properly decode element id when emulating hash scrolling via <ScrollRestoration> (#10682)
• Typescript: Enhance the return type of Route.lazy to prohibit returning an empty object (#10634)
• SSR: Support proper hydration of Error subclasses such as ReferenceError/TypeError (#10633)

What's Changed

JSON/Text Submissions

6.14.0 adds support for JSON and Text submissions via useSubmit/fetcher.submit since it's not always convenient to have to serialize into FormData if you're working in a client-side SPA. To opt-into these encodings you just need to specify the proper formEncType:

Opt-into application/json encoding:

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/plain encoding:

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"
}

⚠️ Default Behavior Will Change in v7

Please note that to avoid a breaking change, the default behavior will still encode a simple key/value JSON object into a FormData instance:

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
}

This behavior will likely change in v7 so it's best to make any JSON object submissions explicit with formEncType: "application/x-www-form-urlencoded" or formEncType: "application/json" to ease your eventual v7 migration path.

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)

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)
  • 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)
  • ⚠️ Note: 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.)
• Avoid calling shouldRevalidate for fetchers that have not yet completed a data load (#10623)
• Strip basename from the location provided to <ScrollRestoration getKey> to match the useLocation behavior (#10550)
• Strip basename from locations provided to unstable_useBlocker functions to match the useLocation behavior (#10573)
• Fix unstable_useBlocker key issues in StrictMode (#10573)
• Fix generatePath when passed a numeric 0 value parameter (#10612)
• Fix tsc --skipLibCheck:false issues on React 17 (#10622)
• Upgrade typescript to 5.1 (#10581)

Full Changelog: v6.13.0...v6.14.0

Date: 2023-06-14

What's Changed

6.13.0 is really a patch release in spirit but comes with a SemVer minor bump since we added a new future flag.

future.v7_startTransition

The tl;dr; is that 6.13.0 is the same as 6.12.0 bue we've moved the usage of React.startTransition behind an opt-in future.v7_startTransition future flag because we found that there are applications in the wild that are currently using Suspense in ways that are incompatible with React.startTransition.

Therefore, in 6.13.0 the default behavior will no longer leverage React.startTransition:

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

<RouterProvider router={router} />

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

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

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

We recommend folks adopt this flag sooner rather than later to be better compatible with React concurrent mode, but if you run into issues you can continue without the use of React.startTransition until v7. Issues usually boil down to creating net-new promises during the render cycle, so if you run into issues when opting into React.startTransition, you should either lift your promise creation out of the render cycle or put it behind a useMemo.

Minor Changes

• Move React.startTransition usage behinds a future flag (#10596)

Patch Changes

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

Full Changelog: v6.12.1...v6.13.0

Date: 2023-06-08

[!WARNING] Please use version 6.13.0 or later instead of 6.12.0/6.12.1. These versions suffered from some Webpack build/minification issues resulting failed builds or invalid minified code in your production bundles. See #10569 and #10579 for more details.

Patch Changes

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

What's Changed

React.startTransition support

With 6.12.0 we've added better support for suspending components by wrapping the internal router state updates in React.startTransition. This means that, for example, if one of your components in a destination route suspends and you have not provided a Suspense boundary to show a fallback, React will delay the rendering of the new UI and show the old UI until that asynchronous operation resolves. This could be useful for waiting for things such as waiting for images or CSS files to load (and technically, yes, you could use it for data loading but we'd still recommend using loaders for that 😀). For a quick overview of this usage, check out Ryan's demo on Twitter.

Minor Changes

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

Patch Changes

• Allow fetcher revalidations to complete if submitting fetcher is deleted (#10535)
• Re-throw DOMException (DataCloneError) when attempting to perform a PUSH navigation with non-serializable state. (#10427)
• Ensure revalidations happen when hash is present (#10516)
• Upgrade jest and jsdom (#10453)
• Updated dependencies:
  • @remix-run/router@1.6.3 (Changelog)

Patch Changes

• Fix basename duplication in descendant <Routes> inside a <RouterProvider> (#10492)
• Fix bug where initial data load would not kick off when hash is present (#10493)
• Export SetURLSearchParams type (#10444)
• Fix Remix HMR-driven error boundaries by properly reconstructing new routes and manifest in _internalSetRoutes (#10437)

Date: 2023-05-03

Patch Changes

• Fix usage of Component API within descendant <Routes> (#10434)
• Fix bug when calling useNavigate from <Routes> inside a <RouterProvider> (#10432)
• Fix usage of <Navigate> in strict mode when using a data router (#10435)
• Fix basename handling when navigating without a path (#10433)
• "Same hash" navigations no longer re-run loaders to match browser behavior (i.e. /path#hash -> /path#hash) (#10408)

Full Changelog: v6.11.0...v6.11.1

Date: 2023-04-28

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'))
• Updated dependencies:
  • @remix-run/router@1.6.0 (Changelog)

Patch Changes

• 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() (#10336)
  • When using BrowserRouter, these hooks remain unstable across location changes because they still rely on useLocation()
• Fetchers should no longer revalidate on search params changes or routing to the same URL, and will only revalidate on action submissions or router.revalidate calls (#10344)
• 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 foot guns in useEffect calls. (#10377, #10409)
• Log loader/action errors caught by the default error boundary to the console in dev for easier stack trace evaluation (#10286)
• Fix bug preventing rendering of descendant <Routes> when RouterProvider errors existed (#10374)
• Fix detection of useNavigate in the render cycle by setting the activeRef in a layout effect, allowing the navigate function to be passed to child components and called in a useEffect there (#10394)
• Allow useRevalidator() to resolve a loader-driven error boundary scenario (#10369)
• Enhance LoaderFunction/ActionFunction return type to prevent undefined from being a valid return value (#10267)
• Ensure proper 404 error on fetcher.load call to a route without a loader (#10345)
• Decouple AbortController usage between revalidating fetchers and the thing that triggered them such that the unmount/deletion of a revalidating fetcher doesn't impact the ongoing triggering navigation/revalidation (#10271)

Full Changelog: v6.10.0...v6.11.0

Date: 2023-03-29

What's Changed

We recently published a post over on the Remix Blog titled "Future Proofing Your Remix App" that goes through our strategy to ensure smooth upgrades for your Remix and React Router apps going forward. React Router 6.10.0 adds support for these flags (for data routers) which you can specify when you create your router:

const router = createBrowserRouter(routes, {
  future: {
    // specify future flags here
  },
});

You can also check out the docs here and here.

Minor Changes

future.v7_normalizeFormMethod

The first future 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() (and some Remix) behavior. (#10207)

• When future.v7_normalizeFormMethod is unspecified or set to 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

• Fix createStaticHandler to also check for ErrorBoundary on routes in addition to errorElement (#10190)
• Fix route ID generation when using Fragments in createRoutesFromElements (#10193)
• Provide fetcher submission to shouldRevalidate if the fetcher action redirects (#10208)
• Properly handle lazy() errors during router initialization (#10201)
• Remove instanceof check for DeferredData to be resilient to ESM/CJS boundaries in SSR bundling scenarios (#10247)
• Update to latest @remix-run/web-fetch@4.3.3 (#10216)

Full Changelog: v6.9.0...v6.10.0

Date: 2023-03-10

What's Changed

Component/ErrorBoundary route properties

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"

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

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. For more info, check out the lazy docs.
