React Router Releases

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:

  • Pagination in the Github UI means that you cannot easily search release notes for a large span of releases at once
  • The paginated Github interface also cuts off longer releases notes without indication in list view, and you need to click into the detail view to see the full set of release notes

v7.0.0

Date: 2024-11-21

Breaking Changes

Package Restructuring

  • The react-router-dom, @remix-run/react, @remix-run/server-runtime, and @remix-run/router have been collapsed into the react-router package
    • To ease migration, react-router-dom is still published in v7 as a re-export of everything from react-router
  • The @remix-run/cloudflare-pages and @remix-run/cloudflare-workers have been collapsed into @react-router/cloudflare package`
  • The react-router-dom-v5-compat and react-router-native packages are removed starting with v7

Removed Adapter Re-exports

Remix 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";

Removed APIs

The following APIs have been removed in React Router v7:

  • json
  • defer
  • unstable_composeUploadHandlers
  • unstable_createMemoryUploadHandler
  • unstable_parseMultipartFormData

Minimum Versions

React Router v7 requires the following minimum versions:

  • node@20
    • React Router no longer provides an installGlobals method to polyfill the fetch API
  • react@18, react-dom@18

Adopted Future Flag Behaviors

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:

  • React Router v6 flags
    • future.v7_relativeSplatPath
    • future.v7_startTransition
    • future.v7_fetcherPersist
    • future.v7_normalizeFormMethod
    • future.v7_partialHydration
    • future.v7_skipActionStatusRevalidation
  • Remix v2 flags
    • future.v3_fetcherPersist
    • future.v3_relativeSplatPath
    • future.v3_throwAbortReason
    • future.v3_singleFetch
    • future.v3_lazyRouteDiscovery
    • future.v3_optimizeDeps

Vite Compiler

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;

Exposed Router Promises

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()

Other Notable Changes

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"),
+  ]),
+];

Typesafety improvements

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.

Prerendering

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"];
}

Major Changes (react-router)

  • Remove the original defer implementation in favor of using raw promises via single fetch and turbo-stream (#11744)
    • This removes these exports from React Router:
      • defer
      • AbortedDeferredError
      • type TypedDeferredData
      • UNSAFE_DeferredData
      • UNSAFE_DEFERRED_SYMBOL
  • Collapse packages into react-router(#11505)
    • @remix-run/router
    • react-router-dom
    • @remix-run/server-runtime
    • @remix-run/testing
    • As a note, the react-router-dom package is maintained to ease adoption but it simply re-exports all APIs from react-router
  • Drop support for Node 16, React Router SSR now requires Node 18 or higher (#11391, #11690)
  • Remove future.v7_startTransition flag (#11696)
  • Expose the underlying router promises from the following APIs for composition in React 19 APIs: (#11521)
  • Remove future.v7_normalizeFormMethod future flag (#11697)
  • Imports/Exports cleanup (#11840)
    • Removed the following exports that were previously public API from @remix-run/router
      • types
        • AgnosticDataIndexRouteObject
        • AgnosticDataNonIndexRouteObject
        • AgnosticDataRouteMatch
        • AgnosticDataRouteObject
        • AgnosticIndexRouteObject
        • AgnosticNonIndexRouteObject
        • AgnosticRouteMatch
        • AgnosticRouteObject
        • TrackedPromise
        • unstable_AgnosticPatchRoutesOnMissFunction
        • Action -> exported as NavigationType via react-router
        • Router exported as RemixRouter to differentiate from RR's <Router>
      • API
        • getToPathname (@private)
        • joinPaths (@private)
        • normalizePathname (@private)
        • resolveTo (@private)
        • stripBasename (@private)
        • createBrowserHistory -> in favor of createBrowserRouter
        • createHashHistory -> in favor of createHashRouter
        • createMemoryHistory -> in favor of createMemoryRouter
        • createRouter
        • createStaticHandler -> in favor of wrapper createStaticHandler in RR Dom
        • getStaticContextFromError
    • Removed the following exports that were previously public API from react-router
      • Hash

      • Search
  • Remove future.v7_prependBasename from the internalized @remix-run/router package (#11726)
  • Remove future.v7_throwAbortReason from internalized @remix-run/router package (#11728)
  • Add exports field to all packages (#11675)
  • Renamed RemixContext to FrameworkContext (#11705)
  • Update the minimum React version to 18 (#11689)
  • PrefetchPageDescriptor replaced by PageLinkDescriptor (#11960)
  • Remove the future.v7_partialHydration flag (#11725)
    • This also removes the <RouterProvider fallbackElement> prop
      • To migrate, move the fallbackElement to a hydrateFallbackElement/HydrateFallback on your root route
    • Also worth nothing there is a related breaking changer with this future flag:
      • Without future.v7_partialHydration (when using fallbackElement), state.navigation was populated during the initial load
      • With future.v7_partialHydration, state.navigation remains in an "idle" state during the initial load
  • Remove future.v7_relativeSplatPath future flag (#11695)
  • Remove remaining future flags (#11820)
    • React Router v7_skipActionErrorRevalidation
    • Remix v3_fetcherPersist, v3_relativeSplatPath, v3_throwAbortReason
  • Rename createRemixStub to createRoutesStub (#11692)
  • Remove @remix-run/router deprecated detectErrorBoundary option in favor of mapRouteProperties (#11751)
  • Add react-router/dom subpath export to properly enable react-dom as an optional peerDependency (#11851)
    • This ensures that we don't blindly import ReactDOM from "react-dom" in <RouterProvider> in order to access ReactDOM.flushSync(), since that would break createMemoryRouter use cases in non-DOM environments
    • DOM environments should import from react-router/dom to get the proper component that makes ReactDOM.flushSync() available:
      • If you are using the Vite plugin, use this in your entry.client.tsx:
        • import { HydratedRouter } from 'react-router/dom'
      • If you are not using the Vite plugin and are manually calling createBrowserRouter/createHashRouter:
        • import { RouterProvider } from "react-router/dom"
  • Remove future.v7_fetcherPersist flag (#11731)
  • Allow returning undefined from loaders and actions (#11680, #12057)
  • Use createRemixRouter/RouterProvider in entry.client instead of RemixBrowser (#11469)
  • Remove the deprecated json utility (#12146)
    • You can use Response.json if you still need to construct JSON responses in your app

Major Changes (@react-router/*)

  • Remove future.v3_singleFetch flag (#11522)
  • Drop support for Node 16 and 18, update minimum Node version to 20 (#11690, #12171)
    • Remove installGlobals() as this should no longer be necessary
  • Add exports field to all packages (#11675)
  • No longer re-export APIs from react-router through different runtime/adapter packages (#11702)
  • For Remix consumers migrating to React Router, the crypto global from the Web Crypto API is now required when using cookie and session APIs
    • This means that the following APIs are provided from react-router rather than platform-specific packages: (#11837)
      • createCookie
      • createCookieSessionStorage
      • createMemorySessionStorage
      • createSessionStorage
    • For consumers running older versions of Node, the installGlobals function from @remix-run/node has been updated to define globalThis.crypto, using Node's require('node:crypto').webcrypto implementation
    • Since platform-specific packages no longer need to implement this API, the following low-level APIs have been removed:
      • createCookieFactory
      • createSessionStorageFactory
      • createCookieSessionStorageFactory
      • createMemorySessionStorageFactory
  • Consolidate types previously duplicated across @remix-run/router, @remix-run/server-runtime, and @remix-run/react now that they all live in react-router (#12177)
    • Examples: LoaderFunction, LoaderFunctionArgs, ActionFunction, ActionFunctionArgs, DataFunctionArgs, RouteManifest, LinksFunction, Route, EntryRoute
    • The RouteManifest type used by the "remix" code is now slightly stricter because it is using the former @remix-run/router RouteManifest
      • Record<string, Route> -> Record<string, Route | undefined>
    • Removed AppData type in favor of inlining unknown in the few locations it was used
    • Removed ServerRuntimeMeta* types in favor of the Meta* types they were duplicated from
  • Migrate Remix v2 type generics to React Router (#12180)
    • These generics are provided for Remix v2 migration purposes
    • These generics and the APIs they exist on should be considered informally deprecated in favor of the new Route.* types
    • Anyone migrating from React Router v6 should probably not leverage these new generics and should migrate straight to the Route.* types
    • For React Router v6 users, these generics are new and should not impact your app, with one exception
      • useFetcher previously had an optional generic (used primarily by Remix v2) that expected the data type
      • This has been updated in v7 to expect the type of the function that generates the data (i.e., typeof loader/typeof action)
      • Therefore, you should update your usages:
        • ❌ useFetcher<LoaderData>()
        • ✅ useFetcher<typeof loader>()
  • Update cookie dependency to ^1.0.1 - please see the release notes for any breaking changes (#12172)
  • @react-router/cloudflare - For Remix consumers migrating to React Router, all exports from @remix-run/cloudflare-pages are now provided for React Router consumers in the @react-router/cloudflare package. There is no longer a separate package for Cloudflare Pages. (#11801)
  • @react-router/cloudflare - The @remix-run/cloudflare-workers package has been deprecated. Remix consumers migrating to React Router should use the @react-router/cloudflare package directly. For guidance on how to use @react-router/cloudflare within a Cloudflare Workers context, refer to the Cloudflare Workers template. (#11801)
  • @react-router/dev - For Remix consumers migrating to React Router, the vitePlugin and cloudflareDevProxyVitePlugin exports have been renamed and moved. (#11904)
  • @react-router/dev - For Remix consumers migrating to React Router who used the Vite plugin's buildEnd hook, the resolved reactRouterConfig object no longer contains a publicPath property since this belongs to Vite, not React Router (#11575)
  • @react-router/dev - For Remix consumers migrating to React Router, the Vite plugin's manifest option has been removed (#11573)
  • @react-router/dev - Update default isbot version to v5 and drop support for isbot@3 (#11770)
    • If you have isbot@4 or isbot@5 in your package.json:
      • You do not need to make any changes
    • If you have isbot@3 in your package.json and you have your own entry.server.tsx file in your repo
      • You do not need to make any changes
      • You can upgrade to isbot@5 independent of the React Router v7 upgrade
    • If you have isbot@3 in your package.json and you do not have your own entry.server.tsx file in your repo
      • You are using the internal default entry provided by React Router v7 and you will need to upgrade to isbot@5 in your package.json
  • @react-router/dev - 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)
    • Originally the Remix Vite plugin moved all Vite manifests to a root-level 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.

Minor Changes

  • 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)
    • Assets in the build/client/assets folder are served as before, with a 1-year immutable Cache-Control header
    • Static files outside of assets, such as pre-rendered .html and .data files are not served with a specific Cache-Control header
    • .data files are served with Content-Type: text/x-turbo
      • For some reason, when adding this via express.static, it seems to also add a Cache-Control: public, max-age=0 to .data files

Patch Changes

  • Replace substr with substring (#12080)
  • react-router - Fix redirects returned from loaders/actions using data() (#12021)
  • @react-router/dev - Enable prerendering for resource routes (#12200)
  • @react-router/dev - resolve config directory relative to flat output file structure (#12187)

v6.27.0

Date: 2024-10-11

What's Changed

Stabilized APIs

This release stabilizes a handful of "unstable" APIs in preparation for the pending React Router v7 release (see these posts for more info):

  • unstable_dataStrategy → dataStrategy (createBrowserRouter and friends) (Docs)
  • unstable_patchRoutesOnNavigation → patchRoutesOnNavigation (createBrowserRouter and friends) (Docs)
  • unstable_flushSync → flushSync (useSubmit, fetcher.load, fetcher.submit) (Docs)
  • unstable_viewTransition → viewTransition (<Link>, <Form>, useNavigate, useSubmit) (Docs)

Minor Changes

  • Stabilize the unstable_flushSync option for navigations and fetchers (#11989)
  • Stabilize the unstable_viewTransition option for navigations and the corresponding unstable_useViewTransitionState hook (#11989)
  • Stabilize unstable_dataStrategy (#11974)
  • Stabilize unstable_patchRoutesOnNavigation (#11973)
    • Add new PatchRoutesOnNavigationFunctionArgs type for convenience (#11967)

Patch Changes

  • Fix bug when submitting to the current contextual route (parent route with an index child) when an ?index param already exists from a prior submission (#12003)
  • Fix useFormAction bug - when removing ?index param it would not keep other non-Remix index params (#12003)
  • Fix bug with fetchers not persisting preventScrollReset through redirects during concurrent fetches (#11999)
  • Avoid unnecessary console.error on fetcher abort due to back-to-back revalidation calls (#12050)
  • Fix bugs with partialHydration when hydrating with errors (#12070)
  • Remove internal cache to fix issues with interrupted patchRoutesOnNavigation calls (#12055)
    • ⚠️ This may be a breaking change if you were relying on this behavior in the unstable_ API
    • We used to cache in-progress calls to patchRoutesOnNavigation internally so that multiple navigations with the same start/end would only execute the function once and use the same promise
    • However, this approach was at odds with patch short circuiting if a navigation was interrupted (and the request.signal aborted) since the first invocation's patch would no-op
    • This cache also made some assumptions as to what a valid cache key might be - and is oblivious to any other application-state changes that may have occurred
    • So, the cache has been removed because in most cases, repeated calls to something like import() for async routes will already be cached automatically - and if not it's easy enough for users to implement this cache in userland
  • Remove internal discoveredRoutes FIFO queue from unstable_patchRoutesOnNavigation (#11977)
    • ⚠️ This may be a breaking change if you were relying on this behavior in the unstable_ API
    • This was originally implemented as an optimization but it proved to be a bit too limiting
    • If you need this optimization you can implement your own cache inside patchRoutesOnNavigation
  • Fix types for RouteObject within PatchRoutesOnNavigationFunction's patch method so it doesn't expect agnostic route objects passed to patch (#11967)
  • Expose errors thrown from patchRoutesOnNavigation directly to useRouteError instead of wrapping them in a 400 ErrorResponse instance (#12111)

Full Changelog: v6.26.2...v6.27.0

v6.26.2

Date: 2024-09-09

Patch Changes

  • Update the unstable_dataStrategy API to allow for more advanced implementations (#11943)
    • ⚠️ If you have already adopted unstable_dataStrategy, please review carefully as this includes breaking changes to this API
    • Rename unstable_HandlerResult to unstable_DataStrategyResult
    • Change the return signature of unstable_dataStrategy from a parallel array of unstable_DataStrategyResult[] (parallel to matches) to a key/value object of routeId => unstable_DataStrategyResult
      • This allows more advanced control over revalidation behavior because you can opt-into or out-of revalidating data that may not have been revalidated by default (via match.shouldLoad)
    • You should now return/throw a result from your handlerOverride instead of returning a DataStrategyResult
      • The return value (or thrown error) from your handlerOverride will be wrapped up into a DataStrategyResult and returned fromm match.resolve
      • Therefore, if you are aggregating the results of match.resolve() into a final results object you should not need to think about the DataStrategyResult type
      • If you are manually filling your results object from within your handlerOverride, then you will need to assign a DataStrategyResult as the value so React Router knows if it's a successful execution or an error (see examples in the documentation for details)
    • Added a new fetcherKey parameter to unstable_dataStrategy to allow differentiation from navigational and fetcher calls
  • Preserve opted-in view transitions through redirects (#11925)
  • Preserve pending view transitions through a router revalidation call (#11917)
  • Fix blocker usage when blocker.proceed is called quickly/synchronously (#11930)

Full Changelog: v6.26.1...v6.26.2

v6.26.1

Date: 2024-08-15

Patch Changes

  • Rename unstable_patchRoutesOnMiss to unstable_patchRoutesOnNavigation to match new behavior (#11888)
  • Update unstable_patchRoutesOnNavigation logic so that we call the method when we match routes with dynamic param or splat segments in case there exists a higher-scoring static route that we've not yet discovered (#11883)
    • We also now leverage an internal FIFO queue of previous paths we've already called unstable_patchRoutesOnNavigation against so that we don't re-call on subsequent navigations to the same path

Full Changelog: v6.26.0...v6.26.1

v6.26.0

Date: 2024-08-01

Minor Changes

  • Add a new replace(url, init?) alternative to redirect(url, init?) that performs a history.replaceState instead of a history.pushState on client-side navigation redirects (#11811)
  • Add a new unstable_data() API for usage with Remix Single Fetch (#11836)
    • This API is not intended for direct usage in React Router SPA applications
    • It is primarily intended for usage with createStaticHandler.query() to allow loaders/actions to return arbitrary data along with custom status/headers without forcing the serialization of data into a Response instance
    • This allows for more advanced serialization tactics via unstable_dataStrategy such as serializing via turbo-stream in Remix Single Fetch
    • ⚠️ This removes the status field from HandlerResult
      • If you need to return a specific status from unstable_dataStrategy you should instead do so via unstable_data()

Patch Changes

  • Fix internal cleanup of interrupted fetchers to avoid invalid revalidations on navigations (#11839)
  • Fix initial hydration behavior when using future.v7_partialHydration along with unstable_patchRoutesOnMiss (#11838)
    • During initial hydration, router.state.matches will now include any partial matches so that we can render ancestor HydrateFallback components

Stabilized v7_skipActionErrorRevalidation

This release stabilizes the future.unstable_skipActionErrorRevalidation flag into future.v7_skipActionErrorRevalidation in preparation for the upcoming React Router v7 release.

  • When this flag is enabled, actions that return/throw a 4xx/5xx Response will not trigger a revalidation by default
  • This also stabilizes shouldRevalidate's unstable_actionStatus parameter to actionStatus

Minor Changes

  • Stabilize future.unstable_skipActionErrorRevalidation as future.v7_skipActionErrorRevalidation (#11769)

Patch Changes

  • Fix regression and properly decode paths inside useMatch so matches/params reflect decoded params (#11789)
  • Fix bubbling of errors thrown from unstable_patchRoutesOnMiss (#11786)

Lazy Route Discovery (a.k.a. "Fog of War")

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]);
      }
    },
  }
);

Minor Changes

  • Add support for Lazy Route Discovery (a.k.a. "Fog of War") (#11626)

Patch Changes

  • Fix fetcher.submit types - remove incorrect navigate/fetcherKey/unstable_viewTransition options because they are only relevant for useSubmit (#11631)

What's Changed

Data Strategy (unstable)

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.

Skip Action Error Revalidation (unstable)

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.

Minor Changes

  • Add a new unstable_dataStrategy configuration option (#11098, #11377)
  • @remix-run/router - Add a new future.unstable_skipActionRevalidation future flag (#11098)
  • @remix-run/router - SSR: Added a new skipLoaderErrorBubbling options to the staticHandler.query method to disable error bubbling by the static handler for use in Remix's Single Fetch implementation (#11098, (#11377))

Core Web Vitals Technology Report Flag

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.

Minor Changes

  • Include a window.__reactRouterVersion for CWV Report detection (#11222)
  • Add a createStaticHandler future.v7_throwAbortReason flag to throw request.signal.reason (defaults to a DOMException) when a request is aborted instead of an Error such as new Error("query() call aborted: GET /path") (#11104)
    • Please note that DOMException was added in Node v17 so you will not get a DOMException on Node 16 and below.

What's Changed

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.

Partial Hydration

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)

Minor Changes

  • Add a new future.v7_relativeSplatPath flag to implement a breaking bug fix to relative routing when inside a splat route. (#11087)
  • Add a new future.v7_partialHydration future flag that enables partial hydration of a data router when Server-Side Rendering (#11033)

Patch Changes

  • Properly handle falsy error values in ErrorBoundary's (#11071)
  • Catch and bubble errors thrown when trying to unwrap responses from loader/action functions (#11061)
  • Fix relative="path" issue when rendering Link/NavLink outside of matched routes (#11062)

    • This fix was included in versions 6.19.0 and 6.20.0. If you are upgrading from 6.18.0 or earlier, you would not have been impacted by this fix.

  • 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

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)

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

v6.16.0

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)

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)

v6.13.0

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)

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:

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

v6.11.0

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:

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

v6.10.0

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/[email protected] (#10216)

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

v6.9.0

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.

Full Changelog: v6.8.0...v6.8.1

v6.8.0

Date: 2023-01-26

Minor Changes

Support absolute URLs in <Link to>. If the URL is for the current origin, it will still do a client-side navigation. If the URL is for a different origin then it will do a fresh document request for the new origin. (#9900)

<Link to="https://neworigin.com/some/path">    {/* Document request */}
<Link to="//neworigin.com/some/path">          {/* Document request */}
<Link to="https://www.currentorigin.com/path"> {/* Client-side navigation */}

Patch Changes

  • Fixes 2 separate issues for revalidating fetcher shouldRevalidate calls (#9948)
    • The 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.
    • The parameters being passed were incorrect and inconsistent with one another since the 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.
  • Fix bug with search params removal via useSearchParams (#9969)
  • Respect preventScrollReset on <fetcher.Form> (#9963)
  • Fix navigation for hash routers on manual URL changes (#9980)
  • Use pagehide instead of beforeunload for <ScrollRestoration>. This has better cross-browser support, specifically on Mobile Safari. (#9945)
  • Do not short circuit on hash change only mutation submissions (#9944)
  • Remove instanceof check from isRouteErrorResponse to avoid bundling issues on the server (#9930)
  • Detect when a defer call only contains critical data and remove the AbortController (#9965)
  • Send the name as the value when url-encoding File FormData entries (#9867)

Full Changelog: v6.5.0...v6.6.0

v6.5.0

Date: 2022-12-16

What's Changed

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

Minor Changes

  • Allows optional routes and optional static segments (#9650)

Patch Changes

  • Stop incorrectly matching on partial named parameters, i.e. <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"
  ...
}
  • Persist headers on loader request's after SSR document action request (#9721)
  • Fix requests sent to revalidating loaders so they reflect a GET request (#9660)
  • Fix issue with deeply nested optional segments (#9727)
  • GET forms now expose a submission on the loading navigation (#9695)
  • Fix error boundary tracking for multiple errors bubbling to the same boundary (#9702)

Full Changelog: v6.4.5...v6.5.0

v6.4.5

Date: 2022-12-07

Patch Changes

  • Fix requests sent to revalidating loaders so they reflect a GET request (#9680)
  • Remove instanceof Response checks in favor of isResponse (#9690)
  • Fix URL creation in Cloudflare Pages or other non-browser-environments (#9682, #9689)
  • Add requestContext support to static handler query/queryRoute (#9696)
    • Note that the unstable API of queryRoute(path, routeId) has been changed to queryRoute(path, { routeId, requestContext })

Full Changelog: v6.4.4...v6.4.5

v6.4.4

Date: 2022-11-30

Patch Changes

  • Throw an error if an action/loader function returns undefined as revalidations need to know whether the loader has previously been executed. undefined also causes issues during SSR stringification for hydration. You should always ensure your loader/action returns a value, and you may return null if you don't wish to return anything. (#9511)
  • Properly handle redirects to external domains (#9590, #9654)
  • Preserve the HTTP method on 307/308 redirects (#9597)
  • Support basename in static data routers (#9591)
  • Enhanced ErrorResponse bodies to contain more descriptive text in internal 403/404/405 scenarios
  • Fix issues with encoded characters in NavLink and descendant <Routes> (#9589, #9647)
  • Properly serialize/deserialize ErrorResponse instances when using built-in hydration (#9593)
  • Support basename in static data routers (#9591)

  • Fix IndexRouteObject and NonIndexRouteObject types to make hasErrorElement optional (#9394)
  • Enhance console error messages for invalid usage of data router hooks (#9311)

v6.1.1

Date: 2021-12-11

Patch Changes

  • In v6.1.0 we inadvertently shipped a new, undocumented API that will likely introduce bugs (#7586). We have flagged HistoryRouter as unstable_HistoryRouter, as this API will likely need to change before a new major release.

v6.1.0

Date: 2021-12-10

Minor Changes

  • <Outlet> can now receive a context prop. This value is passed to child routes and is accessible via the new useOutletContext hook. See the API docs for details. (#8461)
  • <NavLink> can now receive a child function for access to its props. (#8164)
  • Improved TypeScript signature for useMatch and matchPath. For example, when you call useMatch("foo/:bar/:baz"), the path is parsed and the return type will be PathMatch<"bar" | "baz">. (#8030)

Patch Changes

  • Fixed a bug that broke support for base64 encoded IDs on nested routes (#8291)
  • A few error message improvements (#8202)

Full Changelog: v6.0.2...v6.1.0

v6.0.2
