react-router)@react-router/*)This page lists all releases/release notes for React Router back to v6.0.0. For releases prior to v6, please refer to the Github Releases Page.
We manage release notes in this file instead of the paginated Github Releases Page for 2 reasons:
v6.28.0...v7.0.0
Date: 2024-11-21
react-router-dom, @remix-run/react, @remix-run/server-runtime, and @remix-run/router have been collapsed into the react-router package
react-router-dom is still published in v7 as a re-export of everything from react-router@remix-run/cloudflare-pages and @remix-run/cloudflare-workers have been collapsed into @react-router/cloudflare package`react-router-dom-v5-compat and react-router-native packages are removed starting with v7Remix v2 used to re-export all common @remix-run/server-runtime APIs through the various runtime packages (node, cloudflare, deno) so that you wouldn't need an additional @remix-run/server-runtime dependency in your package.json. With the collapsing of packages into react-router, these common APIs are now no longer re-exported through the runtime adapters. You should import all common APIs from react-router, and only import runtime-specific APIs from the runtime packages:
// Runtime-specific APIs
import { createFileSessionStorage } from "@react-router/node";
// Runtime-agnostic APIs
import { redirect, useLoaderData } from "react-router";
The following APIs have been removed in React Router v7:

Instead, breaking changes are introduce din minor releases behind a flag, allowing users to opt-in at their convenience. In the next major release, all future flag behaviors become the default behavior.
The following previously flagged behaviors are now the default in React Router v7:
future.v7_relativeSplatPathfuture.v7_startTransitionfuture.v7_fetcherPersistfuture.v7_normalizeFormMethodfuture.v7_partialHydrationfuture.v7_skipActionStatusRevalidationfuture.v3_fetcherPersistfuture.v3_relativeSplatPathfuture.v3_throwAbortReasonfuture.v3_singleFetchfuture.v3_lazyRouteDiscoveryfuture.v3_optimizeDepsThe Remix Vite plugin is the proper way to build full-stack SSR apps using React Router v7. The former esbuild-based compiler is no longer available.
Renamed vitePlugin and cloudflareDevProxyVitePlugin
For Remix consumers migrating to React Router, the vitePlugin and cloudflareDevProxyVitePlugin exports have been renamed and moved (#11904)
-import {
- vitePlugin as remix,
- cloudflareDevProxyVitePlugin,
-} from "@remix/dev";
+import { reactRouter } from "@react-router/dev/vite";
+import { cloudflareDevProxy } from "@react-router/dev/vite/cloudflare";
Removed manifest option
For Remix consumers migrating to React Router, the Vite plugin's manifest option has been removed. The manifest option been superseded by the more powerful buildEnd hook since it's passed the buildManifest argument. You can still write the build manifest to disk if needed, but you'll most likely find it more convenient to write any logic depending on the build manifest within the buildEnd hook itself. (#11573)
If you were using the manifest option, you can replace it with a buildEnd hook that writes the manifest to disk like this:
// react-router.config.ts
import { type Config } from "@react-router/dev/config";
import { writeFile } from "node:fs/promises";
export default {
async buildEnd({ buildManifest }) {
await writeFile(
"build/manifest.json",
JSON.stringify(buildManifest, null, 2),
"utf-8"
);
},
} satisfies Config;
Because React 19 will have first-class support for handling promises in the render pass (via React.use and useAction), we are now comfortable exposing the promises for the APIs that previously returned undefined:
useNavigate()useSubmit()useFetcher().loaduseFetcher().submituseRevalidator().revalidate()routes.tsWhen using the React Router Vite plugin, routes are defined in app/routes.ts. Route config is exported via the routes export, conforming to the RouteConfig type. Route helper functions route, index, and layout are provided to make declarative type-safe route definitions easier.
// app/routes.ts
import {
type RouteConfig,
route,
index,
layout,
} from "@react-router/dev/routes";
export const routes: RouteConfig = [
index("./home.tsx"),
route("about", "./about.tsx"),
layout("./auth/layout.tsx", [
route("login", "./auth/login.tsx"),
route("register", "./auth/register.tsx"),
]),
route("concerts", [
index("./concerts/home.tsx"),
route(":city", "./concerts/city.tsx"),
route("trending", "./concerts/trending.tsx"),
]),
];
For Remix consumers migrating to React Router, you can still configure file system routing within routes.ts using the @react-router/fs-routes package. A minimal route config that reproduces the default Remix setup looks like this:
// app/routes.ts
import { type RouteConfig } from "@react-router/dev/routes";
import { flatRoutes } from "@react-router/fs-routes";
export const routes: RouteConfig = flatRoutes();
If you want to migrate from file system routing to config-based routes, you can mix and match approaches by spreading the results of the async flatRoutes function into the array of config-based routes.
// app/routes.ts
import { type RouteConfig, route } from "@react-router/dev/routes";
import { flatRoutes } from "@react-router/fs-routes";
export const routes: RouteConfig = [
// Example config-based route:
route("/hello", "./routes/hello.tsx"),
// File system routes scoped to a different directory:
...(await flatRoutes({
rootDirectory: "fs-routes",
})),
];
If you were using Remix's routes option to use alternative file system routing conventions, you can adapt these to the new RouteConfig format using @react-router/remix-config-routes-adapter.
For example, if you were using Remix v1 route conventions in Remix v2, you can combine @react-router/remix-config-routes-adapter with @remix-run/v1-route-convention to adapt this to React Router:
// app/routes.ts
import { type RouteConfig } from "@react-router/dev/routes";
import { remixConfigRoutes } from "@react-router/remix-config-routes-adapter";
import { createRoutesFromFolders } from "@remix-run/v1-route-convention";
export const routes: RouteConfig = remixConfigRoutes(async (defineRoutes) => {
return createRoutesFromFolders(defineRoutes, {
ignoredFilePatterns: ["**/.*", "**/*.css"],
});
});
Also note that, if you were using Remix's routes option to define config-based routes, you can also adapt these to the new RouteConfig format using @react-router/remix-config-routes-adapter with minimal code changes. While this makes for a fast migration path, we recommend migrating any config-based routes from Remix to the new RouteConfig format since it's a fairly straightforward migration.
// app/routes.ts
-import { type RouteConfig } from "@react-router/dev/routes";
+import { type RouteConfig, route } from "@react-router/dev/routes";
-import { remixConfigRoutes } from "@react-router/remix-config-routes-adapter";
-export const routes: RouteConfig = remixConfigRoutes(async (defineRoutes) => {
- defineRoutes((route) => {
- route("/parent", "./routes/parent.tsx", () => [
- route("/child", "./routes/child.tsx"),
- ]);
- });
-});
+export const routes: RouteConfig = [
+ route("/parent", "./routes/parent.tsx", [
+ route("/child", "./routes/child.tsx"),
+ ]),
+];
React Router now generates types for each of your route modules and passes typed props to route module component exports (#11961, #12019). You can access those types by importing them from ./+types/<route filename without extension>.
See How To > Route Module Type Safety and Explanations > Type Safety for more details.
React Router v7 includes a new prerender config in the vite plugin to support SSG use-cases. This will pre-render your .html and .data files at build time and so you can serve them statically at runtime from a running server or a CDN (#11539)
export default defineConfig({
plugins: [
reactRouter({
async prerender({ getStaticPaths }) {
let slugs = await fakeGetSlugsFromCms();
return [
...getStaticPaths(),
...slugs.map((slug) => `/product/${slug}`),
];
},
}),
tsconfigPaths(),
],
});
async function fakeGetSlugsFromCms() {
await new Promise((r) => setTimeout(r, 1000));
return ["shirt", "hat"];
}

This means that the build output is now much closer to what you'd expect from a typical Vite project. (#11573)
build/.vite directory to avoid accidentally serving them in production, particularly from the client build. This was later improved with additional logic that deleted these Vite manifest files at the end of the build process unless Vite's build.manifest had been enabled within the app's Vite config. This greatly reduced the risk of accidentally serving the Vite manifests in production since they're only present when explicitly asked for. As a result, we can now assume that consumers will know that they need to manage these additional files themselves, and React Router can safely generate a more standard Vite build output.react-router - Params, loader data, and action data as props for route component exports (#11961)react-router - Add route module type generation (#12019)react-router - Remove duplicate RouterProvider implementations (#11679)react-router - Stabilize unstable_dataStrategy (#11969)react-router - Stabilize unstable_patchRoutesOnNavigation (#11970)react-router - Add prefetching support to Link/NavLink when using Remix SSR (#11402)react-router - Enhance ScrollRestoration so it can restore properly on an SSR'd document load (#11401)@react-router/dev - Add support for the prerender config in the React Router vite plugin, to support existing SSG use-cases (#11539)@react-router/dev - Remove internal entry.server.spa.tsx implementation which was not compatible with the Single Fetch async hydration approach (#11681)@react-router/serve: Update express.static configurations to support new prerender API (#11547)

We're really excited to release our new API for "Lazy Route Discovery" in v6.24.0! For some background information, please check out the original RFC. The tl;dr; is that ever since we introduced the Data APIs in v6.4 via <RouterProvider>, we've been a little bummed that one of the tradeoffs was the lack of a compelling code-splitting story mirroring what we had in the <BrowserRouter>/<Routes> apps. We took a baby-step towards improving that story with route.lazy in v6.9.0, but with v6.24.0 we've gone the rest of the way.
With "Fog of War", you can now load portions of the route tree lazily via the new unstable_patchRoutesOnMiss option passed to createBrowserRouter (and it's memory/hash counterparts). This gives you a way to hook into spots where React Router is unable to match a given path and patch new routes into the route tree during the navigation (or fetcher call).
Here's a very small example, but please refer to the documentation for more information and use cases:
const router = createBrowserRouter(
[
{
id: "root",
path: "/",
Component: RootComponent,
},
],
{
async unstable_patchRoutesOnMiss({ path, patch }) {
if (path === "/a") {
// Load the `a` route (`{ path: 'a', Component: A }`)
let route = await getARoute();
// Patch the `a` route in as a new child of the `root` route
patch("root", [route]);
}
},
}
);

The new unstable_dataStrategy API is a low-level API designed for advanced use-cases where you need to take control over the data strategy for your loader/action functions. The default implementation is today's behavior, to fetch all loaders in parallel, but this option allows users to implement more advanced data flows including Remix "Single Fetch", user-land middleware/context APIs, automatic loader caching, and more. Please see the docs for more information.
Note: This is a low-level API intended for advanced use-cases. This overrides React Router's internal handling of loader/action execution, and if done incorrectly will break your app code. Please use with caution and perform the appropriate testing.
Currently, all active loader's revalidate after any action submission, regardless of the action result. However, in the majority of cases a 4xx/5xx response from an action means that no data was actually changed and the revalidation is unnecessary. We've introduced a new future.unstable_skipActionErrorRevalidation flag that changes the behavior here, and we plan to make this the default in future version of React Router.
With this flag enabled, action's that return/throw a 4xx/5xx response status will no longer automatically revalidate. If you need to revalidate after a 4xx/5xx result with this flag enabled, you can still do that via returning true from shouldRevalidate - which now also receives a new unstable_actionStatus argument alongside actionResult so you can make decision based on the status of the action response without having to encode it into the action data.

In 2021, the HTTP Archive launched the Core Web Vitals Technology Report dashboard:
By combining the powers of real-user experiences in the Chrome UX Report 26 (CrUX) dataset with web technology detections in HTTP Archive 30, we can get a glimpse into how architectural decisions like choices of CMS platform or JavaScript framework play a role in sites’ CWV performance.
They use a tool called wappalyzer to identify what technologies a given website is using by looking for certain scripts, global JS variables, or other identifying characteristics. For example, for Remix applications, they look for the global __remixContext variable to identify that a website is using Remix.
It was brought to our attention that React Router was unable to be reliably identified because there are no identifying global aspects. They are currently looking for external scripts with react-router in the name. This will identify sites using React Router from a CDN such as unpkg - but it will miss the vast majority of sites that are installing React Router from the npm registry and bundling it into their JS files. This results in drastically under-reporting the usage of React Router on the web.
Starting with version 6.22.0, sites using react-router-dom will begin adding a window.__reactRouterVersion variable that will be set to a string value of the SemVer major version number (i.e., window.__reactRouterVersion = "6";) so that they can be properly identified.

The buggy behavior is that the default behavior when resolving relative paths inside a splat route would ignore any splat (*) portion of the current route path. When the future flag is enabled, splat portions are included in relative path logic within splat routes.
For more information, please refer to the useResolvedPath docs and/or the detailed changelog entry.
We added a new future.v7_partialHydration future flag for the @remix-run/router that enables partial hydration of a data router when Server-Side Rendering. This allows you to provide hydrationData.loaderData that has values for some initially matched route loaders, but not all. When this flag is enabled, the router will call loader functions for routes that do not have hydration loader data during router.initialize(), and it will render down to the deepest provided HydrateFallback (up to the first route without hydration data) while it executes the unhydrated routes.

Per this RFC, we've introduced some new APIs that give you more granular control over your fetcher behaviors.
useFetcher({ key: string }), which allows you to access the same fetcher instance from different components in your application without prop-drillinguseFetchers so that they can be looked up by keyForm 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

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.
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 stateuseFetchers() after completion - they served no purpose in there since you can access the data via useFetcher().dataidle state

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.

Date: 2023-06-23
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.

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_startTransitionThe 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.

React.startTransition supportWith 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.

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.
future.v7_normalizeFormMethodThe 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)

Component/ErrorBoundary route propertiesReact 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() { ... }
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.

shouldRevalidate function was only being called for explicit revalidation scenarios (after a mutation, manual useRevalidator call, or an X-Remix-Revalidate header used for cookie setting in Remix). It was not properly being called on implicit revalidation scenarios that also apply to navigation loader revalidation, such as a change in search params or clicking a link for the page we're already on. It's now correctly called in those additional scenarios.current*/next* parameters reflected the static fetcher.load URL (and thus were identical).

<Route path="/home?"> will match:
//home<Route path="/fr?/about"> will match:
/about/fr/about<Route path="prefix-:param">, to align with how splat parameters work. If you were previously relying on this behavior then it's recommended to extract the static portion of the path at the useParams call site: (#9506)// Old behavior at URL /prefix-123
<Route path="prefix-:id" element={<Comp /> }>
function Comp() {
let params = useParams(); // { id: '123' }
let id = params.id; // "123"
...
}
// New behavior at URL /prefix-123
<Route path=":id" element={<Comp /> }>
function Comp() {
let params = useParams(); // { id: 'prefix-123' }
let id = params.id.replace(/^prefix-/, ''); // "123"

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.
