. 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:
Date: 2024-12-02
Temporarily only use one build in export map so packages can have a peer dependency on react router (#12437)
Support moduleResolution
Node16
and NodeNext
(#12440)
Generate wide matches
and params
types for child routes (#12397)
At runtime, matches
includes child route matches and params
include child route path parameters.
But previously, we only generated types for parent routes and the current route in matches
and params
.
To align our generated types more closely to the runtime behavior, we now generate more permissive, wider types when accessing child route information.

, and @remix-run/router
have been collapsed into the react-router
package
react-router-dom

@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:
json
defer
unstable_composeUploadHandlers
unstable_createMemoryUploadHandler
unstable_parseMultipartFormData
React Router v7 requires the following minimum versions:
node@20
installGlobals
method to polyfill the fetch
APIreact@18
, react-dom@18
Remix and React Router follow an API Development Strategy leveraging "Future Flags" to avoid introducing a slew of breaking changes in a major release. 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_relativeSplatPath
future.v7_startTransition
future.v7_fetcherPersist
future.v7_normalizeFormMethod
future.v7_partialHydration
future.v7_skipActionStatusRevalidation
future.v3_fetcherPersist
future.v3_relativeSplatPath
future.v3_throwAbortReason
future.v3_singleFetch
future.v3_lazyRouteDiscovery
future.v3_optimizeDeps
The 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().load
useFetcher().submit
useRevalidator().revalidate()
routes.ts
When 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"];

package. There is no longer a separate package for Cloudflare Pages. (#11801)@react-router/cloudflare
- The @remix-run/cloudflare-workers

- For Remix consumers migrating to React Router, Vite manifests (i.e. .vite/manifest.json
) are now written within each build subdirectory, e.g. build/client/.vite/manifest.json
and build/server/.vite/manifest.json
instead of build/.vite/client-manifest.json
and build/.vite/server-manifest.json
. 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

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.

future.v7_relativeSplatPath
We fixed a splat route path-resolution bug in 6.19.0
, but later determined a large number of applications were relying on the buggy behavior, so we reverted the fix in 6.20.1
(see #10983, #11052, #11078).
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. (#11033)

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.

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_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
.

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.

}]
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
calls (#9948)
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). Instead, they should have reflected the navigation that triggered the revalidation (as the form*
parameters did). These parameters now correctly reflect the triggering navigation.useSearchParams

This release introduces support for Optional Route Segments. Now, adding a ?
to the end of any path segment will make that entire segment optional. This works for both static segments and dynamic parameters.
Optional Params Examples
<Route path=":lang?/about>
will match:
/:lang/about
/about
<Route path="/multistep/:widget1?/widget2?/widget3?">
will match:
/multistep
/multistep/:widget1
/multistep/:widget1/:widget2
/multistep/:widget1/:widget2/:widget3
Optional Static Segment Example
<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"
...
}
