Raw Blame History

# `@remix-run/router`
## 1.23.0
### Minor Changes
- Add `fetcherKey` as a parameter to `patchRoutesOnNavigation` ([#13109](https://github.com/remix-run/react-router/pull/13109))
### Patch Changes
- Fix regression introduced in `6.29.0` via [#12169](https://github.com/remix-run/react-router/pull/12169) that caused issues navigating to hash routes inside splat routes for applications using Lazy Route Discovery (`patchRoutesOnNavigation`) ([#13108](https://github.com/remix-run/react-router/pull/13108))
## 1.22.0
### Minor Changes
- Provide the request `signal` as a parameter to `patchRoutesOnNavigation` ([#12900](https://github.com/remix-run/react-router/pull/12900))
- This can be used to abort any manifest fetches if the in-flight navigation/fetcher is aborted
### Patch Changes
- Do not log v7 deprecation warnings in production builds ([#12794](https://github.com/remix-run/react-router/pull/12794))
- Strip search parameters from `patchRoutesOnNavigation` `path` param for fetcher calls ([#12899](https://github.com/remix-run/react-router/pull/12899))
- Properly bubble headers when throwing a `data()` result ([#12845](https://github.com/remix-run/react-router/pull/12845))
- Optimize route matching by skipping redundant `matchRoutes` calls when possible ([#12169](https://github.com/remix-run/react-router/pull/12169))
## 1.21.1
### Patch Changes
- - Fix issue with fetcher data cleanup in the data layer on fetcher unmount ([#12674](https://github.com/remix-run/react-router/pull/12674))
- Fix behavior of manual fetcher keys when not opted into `future.v7_fetcherPersist`
## 1.21.0
### Minor Changes
- - Log deprecation warnings for v7 flags ([#11750](https://github.com/remix-run/react-router/pull/11750))
- Add deprecation warnings to `json`/`defer` in favor of returning raw objects
- These methods will be removed in React Router v7
### Patch Changes
- Update JSDoc URLs for new website structure (add /v6/ segment) ([#12141](https://github.com/remix-run/react-router/pull/12141))
## 1.20.0
### Minor Changes
- Stabilize `unstable_patchRoutesOnNavigation` ([#11973](https://github.com/remix-run/react-router/pull/11973))
- Add new `PatchRoutesOnNavigationFunctionArgs` type for convenience ([#11967](https://github.com/remix-run/react-router/pull/11967))
- Stabilize `unstable_dataStrategy` ([#11974](https://github.com/remix-run/react-router/pull/11974))
- Stabilize the `unstable_flushSync` option for navigations and fetchers ([#11989](https://github.com/remix-run/react-router/pull/11989))
- Stabilize the `unstable_viewTransition` option for navigations and the corresponding `unstable_useViewTransitionState` hook ([#11989](https://github.com/remix-run/react-router/pull/11989))
### 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](https://github.com/remix-run/react-router/pull/12003))
- Fix `useFormAction` bug - when removing `?index` param it would not keep other non-Remix `index` params ([#12003](https://github.com/remix-run/react-router/pull/12003))
- Fix bug with fetchers not persisting `preventScrollReset` through redirects during concurrent fetches ([#11999](https://github.com/remix-run/react-router/pull/11999))
- Remove internal cache to fix issues with interrupted `patchRoutesOnNavigation` calls ([#12055](https://github.com/remix-run/react-router/pull/12055))
- 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
- Avoid unnecessary `console.error` on fetcher abort due to back-to-back revalidation calls ([#12050](https://github.com/remix-run/react-router/pull/12050))
- Expose errors thrown from `patchRoutesOnNavigation` directly to `useRouteError` instead of wrapping them in a 400 `ErrorResponse` instance ([#12111](https://github.com/remix-run/react-router/pull/12111))
- Fix types for `RouteObject` within `PatchRoutesOnNavigationFunction`'s `patch` method so it doesn't expect agnostic route objects passed to `patch` ([#11967](https://github.com/remix-run/react-router/pull/11967))
- Fix bugs with `partialHydration` when hydrating with errors ([#12070](https://github.com/remix-run/react-router/pull/12070))
- Remove internal `discoveredRoutes` FIFO queue from `unstable_patchRoutesOnNavigation` ([#11977](https://github.com/remix-run/react-router/pull/11977))
## 1.19.2
### Patch Changes
- Update the `unstable_dataStrategy` API to allow for more advanced implementations ([#11943](https://github.com/remix-run/react-router/pull/11943))
- Rename `unstable_HandlerResult` to `unstable_DataStrategyResult`
- The return signature has changed from a parallel array of `unstable_DataStrategyResult[]` (parallel to `matches`) to a key/value object of `routeId => unstable_DataStrategyResult`
- This allows you to more easily decide to opt-into or out-of revalidating data that may not have been revalidated by default (via `match.shouldLoad`)
- ⚠️ This is a breaking change if you've currently adopted `unstable_dataStrategy`
- Added a new `fetcherKey` parameter to `unstable_dataStrategy` to allow differentiation from navigational and fetcher calls
- You should now return/throw a result from your `handlerOverride` instead of returning a `DataStrategyResult`
- 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.
- Preserve view transition through redirects ([#11925](https://github.com/remix-run/react-router/pull/11925))
- Fix blocker usage when `blocker.proceed` is called quickly/synchronously ([#11930](https://github.com/remix-run/react-router/pull/11930))
- Preserve pending view transitions through a router revalidation call ([#11917](https://github.com/remix-run/react-router/pull/11917))
## 1.19.1
### Patch Changes
- Fog of War: Update `unstable_patchRoutesOnMiss` 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](https://github.com/remix-run/react-router/pull/11883))
- We also now leverage an internal FIFO queue of previous paths we've already called `unstable_patchRouteOnMiss` against so that we don't re-call on subsequent navigations to the same path
- Rename `unstable_patchRoutesOnMiss` to `unstable_patchRoutesOnNavigation` to match new behavior ([#11888](https://github.com/remix-run/react-router/pull/11888))
## 1.19.0
### 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](https://github.com/remix-run/react-router/pull/11811))
- Add a new `unstable_data()` API for usage with Remix Single Fetch ([#11836](https://github.com/remix-run/react-router/pull/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 + `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](https://github.com/remix-run/react-router/pull/11839))
- When a `fetcher.load` is interrupted by an `action` submission, we track it internally and force revalidation once the `action` completes
- We previously only cleared out this internal tracking info on a successful _navigation_ submission
- Therefore, if the `fetcher.load` was interrupted by a `fetcher.submit`, then we wouldn't remove it from this internal tracking info on successful load (incorrectly)
- And then on the next navigation it's presence in the internal tracking would automatically trigger execution of the `fetcher.load` again, ignoring any `shouldRevalidate` logic
- This fix cleans up the internal tracking so it applies to both navigation submission and fetcher submissions
- Fix initial hydration behavior when using `future.v7_partialHydration` along with `unstable_patchRoutesOnMiss` ([#11838](https://github.com/remix-run/react-router/pull/11838))
- During initial hydration, `router.state.matches` will now include any partial matches so that we can render ancestor `HydrateFallback` components
## 1.18.0
### Minor Changes
- Stabilize `future.unstable_skipActionErrorRevalidation` as `future.v7_skipActionErrorRevalidation` ([#11769](https://github.com/remix-run/react-router/pull/11769))
- When this flag is enabled, actions will not automatically trigger a revalidation if they return/throw a `Response` with a `4xx`/`5xx` status code
- You may still opt-into revalidation via `shouldRevalidate`
- This also changes `shouldRevalidate`'s `unstable_actionStatus` parameter to `actionStatus`
### Patch Changes
- Fix bubbling of errors thrown from `unstable_patchRoutesOnMiss` ([#11786](https://github.com/remix-run/react-router/pull/11786))
- Fix hydration in SSR apps using `unstable_patchRoutesOnMiss` that matched a splat route on the server ([#11790](https://github.com/remix-run/react-router/pull/11790))
## 1.17.1
### Patch Changes
- Fog of War (unstable): Trigger a new `router.routes` identity/reflow during route patching ([#11740](https://github.com/remix-run/react-router/pull/11740))
- Fog of War (unstable): Fix initial matching when a splat route matches ([#11759](https://github.com/remix-run/react-router/pull/11759))
## 1.17.0
### Minor Changes
- Add support for Lazy Route Discovery (a.k.a. Fog of War) ([#11626](https://github.com/remix-run/react-router/pull/11626))
- RFC: <https://github.com/remix-run/react-router/discussions/11113>
- `unstable_patchRoutesOnMiss` docs: <https://reactrouter.com/v6/routers/create-browser-router>
## 1.16.1
### Patch Changes
- Support `unstable_dataStrategy` on `staticHandler.queryRoute` ([#11515](https://github.com/remix-run/react-router/pull/11515))
## 1.16.0
### Minor Changes
- Add a new `unstable_dataStrategy` configuration option ([#11098](https://github.com/remix-run/react-router/pull/11098))
- This option allows Data Router applications to take control over the approach for executing route loaders and actions
- 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, middleware/context APIs, automatic loader caching, and more
- Move `unstable_dataStrategy` from `createStaticHandler` to `staticHandler.query` so it can be request-specific for use with the `ResponseStub` approach in Remix. It's not really applicable to `queryRoute` for now since that's a singular handler call anyway so any pre-processing/post/processing could be done there manually. ([#11377](https://github.com/remix-run/react-router/pull/11377))
- Add a new `future.unstable_skipActionRevalidation` future flag ([#11098](https://github.com/remix-run/react-router/pull/11098))
- Currently, active loaders revalidate after any action, regardless of the result
- With this flag enabled, actions that return/throw a 4xx/5xx response status will no longer automatically revalidate
- This should reduce load on your server since it's rare that a 4xx/5xx should actually mutate any data
- If you need to revalidate after a 4xx/5xx result with this flag enabled, you can still do that via returning `true` from `shouldRevalidate`
- `shouldRevalidate` 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
- Added a `skipLoaderErrorBubbling` flag to `staticHandler.query` to disable error bubbling on loader executions for single-fetch scenarios where the client-side router will handle the bubbling ([#11098](https://github.com/remix-run/react-router/pull/11098))
## 1.15.3
### Patch Changes
- Fix a `future.v7_partialHydration` bug that would re-run loaders below the boundary on hydration if SSR loader errors bubbled to a parent boundary ([#11324](https://github.com/remix-run/react-router/pull/11324))
- Fix a `future.v7_partialHydration` bug that would consider the router uninitialized if a route did not have a loader ([#11325](https://github.com/remix-run/react-router/pull/11325))
## 1.15.2
### Patch Changes
- Preserve hydrated errors during partial hydration runs ([#11305](https://github.com/remix-run/react-router/pull/11305))
## 1.15.1
### Patch Changes
- Fix encoding/decoding issues with pre-encoded dynamic parameter values ([#11199](https://github.com/remix-run/react-router/pull/11199))
## 1.15.0
### Minor Changes
- 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](https://github.com/remix-run/react-router/pull/11104))
- Please note that `DOMException` was added in Node v17 so you will not get a `DOMException` on Node 16 and below.
### Patch Changes
- Respect the `ErrorResponse` status code if passed to `getStaticContextFormError` ([#11213](https://github.com/remix-run/react-router/pull/11213))
## 1.14.2
### Patch Changes
- Fix bug where dashes were not picked up in dynamic parameter names ([#11160](https://github.com/remix-run/react-router/pull/11160))
- Do not attempt to deserialize empty JSON responses ([#11164](https://github.com/remix-run/react-router/pull/11164))
## 1.14.1
### Patch Changes
- Fix bug with `route.lazy` not working correctly on initial SPA load when `v7_partialHydration` is specified ([#11121](https://github.com/remix-run/react-router/pull/11121))
- Fix bug preventing revalidation from occurring for persisted fetchers unmounted during the `submitting` phase ([#11102](https://github.com/remix-run/react-router/pull/11102))
- De-dup relative path logic in `resolveTo` ([#11097](https://github.com/remix-run/react-router/pull/11097))
## 1.14.0
### Minor Changes
- Added a new `future.v7_partialHydration` future flag 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](https://github.com/remix-run/react-router/pull/11033))
For example, the following router has a `root` and `index` route, but only provided `hydrationData.loaderData` for the `root` route. Because the `index` route has a `loader`, we need to run that during initialization. With `future.v7_partialHydration` specified, `<RouterProvider>` will render the `RootComponent` (because it has data) and then the `IndexFallback` (since it does not have data). Once `indexLoader` finishes, application will update and display `IndexComponent`.
```jsx
let router = createBrowserRouter(
[
{
id: "root",
path: "/",
loader: rootLoader,
Component: RootComponent,
Fallback: RootFallback,
children: [
{
id: "index",
index: true,
loader: indexLoader,
Component: IndexComponent,
HydrateFallback: IndexFallback,
},
],
},
],
{
future: {
v7_partialHydration: true,
},
hydrationData: {
loaderData: {
root: { message: "Hydrated from Root!" },
},
},
}
);
```
If the above example did not have an `IndexFallback`, then `RouterProvider` would instead render the `RootFallback` while it executed the `indexLoader`.
**Note:** When `future.v7_partialHydration` is provided, the `<RouterProvider fallbackElement>` prop is ignored since you can move it to a `Fallback` on your top-most route. The `fallbackElement` prop will be removed in React Router v7 when `v7_partialHydration` behavior becomes the standard behavior.
- Add a new `future.v7_relativeSplatPath` flag to implement a breaking bug fix to relative routing when inside a splat route. ([#11087](https://github.com/remix-run/react-router/pull/11087))
This fix was originally added in [#10983](https://github.com/remix-run/react-router/issues/10983) and was later reverted in [#11078](https://github.com/remix-run/react-router/pull/11078) because it was determined that a large number of existing applications were relying on the buggy behavior (see [#11052](https://github.com/remix-run/react-router/issues/11052))
**The Bug**
The buggy behavior is that without this flag, the default behavior when resolving relative paths is to _ignore_ any splat (`*`) portion of the current route path.
**The Background**
This decision was originally made thinking that it would make the concept of nested different sections of your apps in `<Routes>` easier if relative routing would _replace_ the current splat:
```jsx
<BrowserRouter>
<Routes>
<Route path="/" element={<Home />} />
<Route path="dashboard/*" element={<Dashboard />} />
</Routes>
</BrowserRouter>
```
Any paths like `/dashboard`, `/dashboard/team`, `/dashboard/projects` will match the `Dashboard` route. The dashboard component itself can then render nested `<Routes>`:
```jsx
function Dashboard() {
return (
<div>
<h2>Dashboard</h2>
<nav>
<Link to="/">Dashboard Home</Link>
<Link to="team">Team</Link>
<Link to="projects">Projects</Link>
</nav>
<Routes>
<Route path="/" element={<DashboardHome />} />
<Route path="team" element={<DashboardTeam />} />
<Route path="projects" element={<DashboardProjects />} />
</Routes>
</div>
);
}
```
Now, all links and route paths are relative to the router above them. This makes code splitting and compartmentalizing your app really easy. You could render the `Dashboard` as its own independent app, or embed it into your large app without making any changes to it.
**The Problem**
The problem is that this concept of ignoring part of a path breaks a lot of other assumptions in React Router - namely that `"."` always means the current location pathname for that route. When we ignore the splat portion, we start getting invalid paths when using `"."`:
```jsx
// If we are on URL /dashboard/team, and we want to link to /dashboard/team:
function DashboardTeam() {
// ❌ This is broken and results in <a href="/dashboard">
return <Link to=".">A broken link to the Current URL</Link>;
// ✅ This is fixed but super unintuitive since we're already at /dashboard/team!
return <Link to="./team">A broken link to the Current URL</Link>;
}
```
We've also introduced an issue that we can no longer move our `DashboardTeam` component around our route hierarchy easily - since it behaves differently if we're underneath a non-splat route, such as `/dashboard/:widget`. Now, our `"."` links will, properly point to ourself _inclusive of the dynamic param value_ so behavior will break from it's corresponding usage in a `/dashboard/*` route.
Even worse, consider a nested splat route configuration:
```jsx
<BrowserRouter>
<Routes>
<Route path="dashboard">
<Route path="*" element={<Dashboard />} />
</Route>
</Routes>
</BrowserRouter>
```
Now, a `<Link to=".">` and a `<Link to="..">` inside the `Dashboard` component go to the same place! That is definitely not correct!
Another common issue arose in Data Routers (and Remix) where any `<Form>` should post to it's own route `action` if you the user doesn't specify a form action:
```jsx
let router = createBrowserRouter({
path: "/dashboard",
children: [
{
path: "*",
action: dashboardAction,
Component() {
// ❌ This form is broken! It throws a 405 error when it submits because
// it tries to submit to /dashboard (without the splat value) and the parent
// `/dashboard` route doesn't have an action
return <Form method="post">...</Form>;
},
},
],
});
```
This is just a compounded issue from the above because the default location for a `Form` to submit to is itself (`"."`) - and if we ignore the splat portion, that now resolves to the parent route.
**The Solution**
If you are leveraging this behavior, it's recommended to enable the future flag, move your splat to it's own route, and leverage `../` for any links to "sibling" pages:
```jsx
<BrowserRouter>
<Routes>
<Route path="dashboard">
<Route index path="*" element={<Dashboard />} />
</Route>
</Routes>
</BrowserRouter>
function Dashboard() {
return (
<div>
<h2>Dashboard</h2>
<nav>
<Link to="..">Dashboard Home</Link>
<Link to="../team">Team</Link>
<Link to="../projects">Projects</Link>
</nav>
<Routes>
<Route path="/" element={<DashboardHome />} />
<Route path="team" element={<DashboardTeam />} />
<Route path="projects" element={<DashboardProjects />} />
</Router>
</div>
);
}
```
This way, `.` means "the full current pathname for my route" in all cases (including static, dynamic, and splat routes) and `..` always means "my parents pathname".
### Patch Changes
- Catch and bubble errors thrown when trying to unwrap responses from `loader`/`action` functions ([#11061](https://github.com/remix-run/react-router/pull/11061))
- Fix `relative="path"` issue when rendering `Link`/`NavLink` outside of matched routes ([#11062](https://github.com/remix-run/react-router/pull/11062))
## 1.13.1
### Patch Changes
- Revert the `useResolvedPath` fix for splat routes due to a large number of applications that were relying on the buggy behavior (see <https://github.com/remix-run/react-router/issues/11052#issuecomment-1836589329>). We plan to re-introduce this fix behind a future flag in the next minor version. ([#11078](https://github.com/remix-run/react-router/pull/11078))
## 1.13.0
### Minor Changes
- Export the `PathParam` type from the public API ([#10719](https://github.com/remix-run/react-router/pull/10719))
### Patch Changes
- Fix bug with `resolveTo` in splat routes ([#11045](https://github.com/remix-run/react-router/pull/11045))
- This is a follow up to [#10983](https://github.com/remix-run/react-router/pull/10983) to handle the few other code paths using `getPathContributingMatches`
- This removes the `UNSAFE_getPathContributingMatches` export from `@remix-run/router` since we no longer need this in the `react-router`/`react-router-dom` layers
- Do not revalidate unmounted fetchers when `v7_fetcherPersist` is enabled ([#11044](https://github.com/remix-run/react-router/pull/11044))
## 1.12.0
### Minor Changes
- Add `unstable_flushSync` option to `router.navigate` and `router.fetch` to tell the React Router layer to opt-out of `React.startTransition` and into `ReactDOM.flushSync` for state updates ([#11005](https://github.com/remix-run/react-router/pull/11005))
### Patch Changes
- Fix `relative="path"` bug where relative path calculations started from the full location pathname, instead of from the current contextual route pathname. ([#11006](https://github.com/remix-run/react-router/pull/11006))
```jsx
<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 />
</>
);
}
```
## 1.11.0
### Minor Changes
- Add a new `future.v7_fetcherPersist` flag to the `@remix-run/router` to change the persistence behavior of fetchers when `router.deleteFetcher` is called. Instead of being immediately cleaned up, fetchers will persist until they return to an `idle` state ([RFC](https://github.com/remix-run/remix/discussions/7698)) ([#10962](https://github.com/remix-run/react-router/pull/10962))
- 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()`. They served effectively 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.
- When `v7_fetcherPersist` is enabled, the router now performs ref-counting on fetcher keys via `getFetcher`/`deleteFetcher` so it knows when a given fetcher is totally unmounted from the UI ([#10977](https://github.com/remix-run/react-router/pull/10977))
- Once a fetcher has been totally unmounted, we can ignore post-processing of a persisted fetcher result such as a redirect or an error
- The router will also pass a new `deletedFetchers` array to the subscriber callbacks so that the UI layer can remove associated fetcher data
- Add support for optional path segments in `matchPath` ([#10768](https://github.com/remix-run/react-router/pull/10768))
### Patch Changes
- Fix `router.getFetcher`/`router.deleteFetcher` type definitions which incorrectly specified `key` as an optional parameter ([#10960](https://github.com/remix-run/react-router/pull/10960))
## 1.10.0
### Minor Changes
- Add experimental support for the [View Transitions API](https://developer.mozilla.org/en-US/docs/Web/API/ViewTransition) by allowing users to opt-into view transitions on navigations via the new `unstable_viewTransition` option to `router.navigate` ([#10916](https://github.com/remix-run/react-router/pull/10916))
### Patch Changes
- Allow 404 detection to leverage root route error boundary if path contains a URL segment ([#10852](https://github.com/remix-run/react-router/pull/10852))
- Fix `ErrorResponse` type to avoid leaking internal field ([#10876](https://github.com/remix-run/react-router/pull/10876))
## 1.9.0
### 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](https://github.com/remix-run/react-router/pull/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](https://github.com/remix-run/react-router/pull/10811))
- Export `ShouldRevalidateFunctionArgs` interface ([#10797](https://github.com/remix-run/react-router/pull/10797))
- Removed private/internal APIs only required for the Remix v1 backwards compatibility layer and no longer needed in Remix v2 (`_isFetchActionRedirect`, `_hasFetcherDoneAnything`) ([#10715](https://github.com/remix-run/react-router/pull/10715))
### Patch Changes
- Add method/url to error message on aborted `query`/`queryRoute` calls ([#10793](https://github.com/remix-run/react-router/pull/10793))
- Fix a race-condition with loader/action-thrown errors on `route.lazy` routes ([#10778](https://github.com/remix-run/react-router/pull/10778))
- Fix type for `actionResult` on the arguments object passed to `shouldRevalidate` ([#10779](https://github.com/remix-run/react-router/pull/10779))
## 1.8.0
### Minor Changes
- Add's a new `redirectDocument()` function which allows users to specify that a redirect from a `loader`/`action` should trigger a document reload (via `window.location`) instead of attempting to navigate to the redirected location via React Router ([#10705](https://github.com/remix-run/react-router/pull/10705))
### Patch Changes
- Fix an issue in `queryRoute` that was not always identifying thrown `Response` instances ([#10717](https://github.com/remix-run/react-router/pull/10717))
- Ensure hash history always includes a leading slash on hash pathnames ([#10753](https://github.com/remix-run/react-router/pull/10753))
## 1.7.2
### Patch Changes
- Trigger an error if a `defer` promise resolves/rejects with `undefined` in order to match the behavior of loaders and actions which must return a value or `null` ([#10690](https://github.com/remix-run/react-router/pull/10690))
- Properly handle fetcher redirects interrupted by normal navigations ([#10674](https://github.com/remix-run/react-router/pull/10674), [#10709](https://github.com/remix-run/react-router/pull/10709))
- Initial-load fetchers should not automatically revalidate on GET navigations ([#10688](https://github.com/remix-run/react-router/pull/10688))
- Enhance the return type of `Route.lazy` to prohibit returning an empty object ([#10634](https://github.com/remix-run/react-router/pull/10634))
## 1.7.1
### Patch Changes
- Fix issues with reused blockers on subsequent navigations ([#10656](https://github.com/remix-run/react-router/pull/10656))
## 1.7.0
### Minor Changes
- Add support for `application/json` and `text/plain` encodings for `router.navigate`/`router.fetch` submissions. To leverage these encodings, pass your data in a `body` parameter and specify the desired `formEncType`: ([#10413](https://github.com/remix-run/react-router/pull/10413))
```js
// By default, the encoding is "application/x-www-form-urlencoded"
router.navigate("/", {
formMethod: "post",
body: { key: "value" },
});
async function action({ request }) {
// await request.formData() => FormData instance with entry [key=value]
}
```
```js
// Pass `formEncType` to opt-into a different encoding (json)
router.navigate("/", {
formMethod: "post",
formEncType: "application/json",
body: { key: "value" },
});
async function action({ request }) {
// await request.json() => { key: "value" }
}
```
```js
// Pass `formEncType` to opt-into a different encoding (text)
router.navigate("/", {
formMethod: "post",
formEncType: "text/plain",
body: "Text submission",
});
async function action({ request }) {
// await request.text() => "Text submission"
}
```
### Patch Changes
- 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](https://github.com/remix-run/react-router/pull/10448))
- ⚠️ However, generally apps should not be relying on `window.location` and should always reference `useLocation` when possible, as `window.location` will not be in sync 100% of the time (due to `popstate` events, concurrent mode, etc.)
- Strip `basename` from the `location` provided to `<ScrollRestoration getKey>` to match the `useLocation` behavior ([#10550](https://github.com/remix-run/react-router/pull/10550))
- Avoid calling `shouldRevalidate` for fetchers that have not yet completed a data load ([#10623](https://github.com/remix-run/react-router/pull/10623))
- Fix `unstable_useBlocker` key issues in `StrictMode` ([#10573](https://github.com/remix-run/react-router/pull/10573))
- Upgrade `typescript` to 5.1 ([#10581](https://github.com/remix-run/react-router/pull/10581))
## 1.6.3
### Patch Changes
- Allow fetcher revalidations to complete if submitting fetcher is deleted ([#10535](https://github.com/remix-run/react-router/pull/10535))
- Re-throw `DOMException` (`DataCloneError`) when attempting to perform a `PUSH` navigation with non-serializable state. ([#10427](https://github.com/remix-run/react-router/pull/10427))
- Ensure revalidations happen when hash is present ([#10516](https://github.com/remix-run/react-router/pull/10516))
- upgrade jest and jsdom ([#10453](https://github.com/remix-run/react-router/pull/10453))
## 1.6.2
### Patch Changes
- Fix HMR-driven error boundaries by properly reconstructing new routes and `manifest` in `\_internalSetRoutes` ([#10437](https://github.com/remix-run/react-router/pull/10437))
- Fix bug where initial data load would not kick off when hash is present ([#10493](https://github.com/remix-run/react-router/pull/10493))
## 1.6.1
### Patch Changes
- Fix `basename` handling when navigating without a path ([#10433](https://github.com/remix-run/react-router/pull/10433))
- "Same hash" navigations no longer re-run loaders to match browser behavior (i.e. `/path#hash -> /path#hash`) ([#10408](https://github.com/remix-run/react-router/pull/10408))
## 1.6.0
### Minor Changes
- Enable relative routing in the `@remix-run/router` when providing a source route ID from which the path is relative to: ([#10336](https://github.com/remix-run/react-router/pull/10336))
- Example: `router.navigate("../path", { fromRouteId: "some-route" })`.
- This also applies to `router.fetch` which already receives a source route ID
- Introduce a new `@remix-run/router` `future.v7_prependBasename` flag to enable `basename` prefixing to all paths coming into `router.navigate` and `router.fetch`.
- Previously the `basename` was prepended in the React Router layer, but now that relative routing is being handled by the router we need prepend the `basename` _after_ resolving any relative paths
- This also enables `basename` support in `useFetcher` as well
### Patch Changes
- Enhance `LoaderFunction`/`ActionFunction` return type to prevent `undefined` from being a valid return value ([#10267](https://github.com/remix-run/react-router/pull/10267))
- Ensure proper 404 error on `fetcher.load` call to a route without a `loader` ([#10345](https://github.com/remix-run/react-router/pull/10345))
- Deprecate the `createRouter` `detectErrorBoundary` option in favor of the new `mapRouteProperties` option for converting a framework-agnostic route to a framework-aware route. This allows us to set more than just the `hasErrorBoundary` property during route pre-processing, and is now used for mapping `Component -> element` and `ErrorBoundary -> errorElement` in `react-router`. ([#10287](https://github.com/remix-run/react-router/pull/10287))
- Fixed a bug where fetchers were incorrectly attempting to revalidate on search params changes or routing to the same URL (using the same logic for route `loader` revalidations). However, since fetchers have a static href, they should only revalidate on `action` submissions or `router.revalidate` calls. ([#10344](https://github.com/remix-run/react-router/pull/10344))
- 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](https://github.com/remix-run/react-router/pull/10271))
## 1.5.0
### Minor Changes
- Added support for [**Future Flags**](https://reactrouter.com/v6/guides/api-development-strategy) in React Router. The first flag being introduced is `future.v7_normalizeFormMethod` which will normalize the exposed `useNavigation()/useFetcher()` `formMethod` fields as uppercase HTTP methods to align with the `fetch()` behavior. ([#10207](https://github.com/remix-run/react-router/pull/10207))
- When `future.v7_normalizeFormMethod === false` (default v6 behavior),
- `useNavigation().formMethod` is lowercase
- `useFetcher().formMethod` is lowercase
- When `future.v7_normalizeFormMethod === true`:
- `useNavigation().formMethod` is uppercase
- `useFetcher().formMethod` is uppercase
### Patch Changes
- Provide fetcher submission to `shouldRevalidate` if the fetcher action redirects ([#10208](https://github.com/remix-run/react-router/pull/10208))
- Properly handle `lazy()` errors during router initialization ([#10201](https://github.com/remix-run/react-router/pull/10201))
- Remove `instanceof` check for `DeferredData` to be resilient to ESM/CJS boundaries in SSR bundling scenarios ([#10247](https://github.com/remix-run/react-router/pull/10247))
- Update to latest `@remix-run/web-fetch@4.3.3` ([#10216](https://github.com/remix-run/react-router/pull/10216))
## 1.4.0
### Minor Changes
- **Introducing Lazy Route Modules!** ([#10045](https://github.com/remix-run/react-router/pull/10045))
In order to keep your application bundles small and support code-splitting of your routes, we've introduced a new `lazy()` route property. This is an async function that resolves the non-route-matching portions of your route definition (`loader`, `action`, `element`/`Component`, `errorElement`/`ErrorBoundary`, `shouldRevalidate`, `handle`).
Lazy routes are resolved on initial load and during the `loading` or `submitting` phase of a navigation or fetcher call. You cannot lazily define route-matching properties (`path`, `index`, `children`) since we only execute your lazy route functions after we've matched known routes.
Your `lazy` functions will typically return the result of a dynamic import.
```jsx
// 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:
```jsx
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`](https://github.com/remix-run/react-router/tree/main/examples/lazy-loading-router-provider) directory of the repository.
🙌 Huge thanks to @rossipedia for the [Initial Proposal](https://github.com/remix-run/react-router/discussions/9826) and [POC Implementation](https://github.com/remix-run/react-router/pull/9830).
### Patch Changes
- Fix `generatePath` incorrectly applying parameters in some cases ([#10078](https://github.com/remix-run/react-router/pull/10078))
## 1.3.3
### Patch Changes
- Correctly perform a hard redirect for same-origin absolute URLs outside of the router `basename` ([#10076](https://github.com/remix-run/react-router/pull/10076))
- Ensure status code and headers are maintained for `defer` loader responses in `createStaticHandler`'s `query()` method ([#10077](https://github.com/remix-run/react-router/pull/10077))
- Change `invariant` to an `UNSAFE_invariant` export since it's only intended for internal use ([#10066](https://github.com/remix-run/react-router/pull/10066))
- Add internal API for custom HMR implementations ([#9996](https://github.com/remix-run/react-router/pull/9996))
## 1.3.2
### Patch Changes
- Remove inaccurate console warning for POP navigations and update active blocker logic ([#10030](https://github.com/remix-run/react-router/pull/10030))
- Only check for differing origin on absolute URL redirects ([#10033](https://github.com/remix-run/react-router/pull/10033))
## 1.3.1
### Patch Changes
- Fixes 2 separate issues for revalidating fetcher `shouldRevalidate` calls ([#9948](https://github.com/remix-run/react-router/pull/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 the navigation that triggered the revalidation (as the `form*` parameters did). These parameters now correctly reflect the triggering navigation.
- Respect `preventScrollReset` on `<fetcher.Form>` ([#9963](https://github.com/remix-run/react-router/pull/9963))
- Do not short circuit on hash change only mutation submissions ([#9944](https://github.com/remix-run/react-router/pull/9944))
- Remove `instanceof` check from `isRouteErrorResponse` to avoid bundling issues on the server ([#9930](https://github.com/remix-run/react-router/pull/9930))
- Fix navigation for hash routers on manual URL changes ([#9980](https://github.com/remix-run/react-router/pull/9980))
- Detect when a `defer` call only contains critical data and remove the `AbortController` ([#9965](https://github.com/remix-run/react-router/pull/9965))
- Send the name as the value when url-encoding `File` `FormData` entries ([#9867](https://github.com/remix-run/react-router/pull/9867))
## 1.3.0
### Minor Changes
- Added support for navigation blocking APIs ([#9709](https://github.com/remix-run/react-router/pull/9709))
- Expose deferred information from `createStaticHandler` ([#9760](https://github.com/remix-run/react-router/pull/9760))
### Patch Changes
- Improved absolute redirect url detection in actions/loaders ([#9829](https://github.com/remix-run/react-router/pull/9829))
- Fix URL creation with memory histories ([#9814](https://github.com/remix-run/react-router/pull/9814))
- Fix `generatePath` when optional params are present ([#9764](https://github.com/remix-run/react-router/pull/9764))
- Fix scroll reset if a submission redirects ([#9886](https://github.com/remix-run/react-router/pull/9886))
- Fix 404 bug with same-origin absolute redirects ([#9913](https://github.com/remix-run/react-router/pull/9913))
- Support `OPTIONS` requests in `staticHandler.queryRoute` ([#9914](https://github.com/remix-run/react-router/pull/9914))
## 1.2.1
### Patch Changes
- Include submission info in `shouldRevalidate` on action redirects ([#9777](https://github.com/remix-run/react-router/pull/9777), [#9782](https://github.com/remix-run/react-router/pull/9782))
- Reset `actionData` on action redirect to current location ([#9772](https://github.com/remix-run/react-router/pull/9772))
## 1.2.0
### Minor Changes
- Remove `unstable_` prefix from `createStaticHandler`/`createStaticRouter`/`StaticRouterProvider` ([#9738](https://github.com/remix-run/react-router/pull/9738))
### Patch Changes
- Fix explicit `replace` on submissions and `PUSH` on submission to new paths ([#9734](https://github.com/remix-run/react-router/pull/9734))
- Fix a few bugs where loader/action data wasn't properly cleared on errors ([#9735](https://github.com/remix-run/react-router/pull/9735))
- Prevent `useLoaderData` usage in `errorElement` ([#9735](https://github.com/remix-run/react-router/pull/9735))
- Skip initial scroll restoration for SSR apps with `hydrationData` ([#9664](https://github.com/remix-run/react-router/pull/9664))
## 1.1.0
This release introduces support for [Optional Route Segments](https://github.com/remix-run/react-router/issues/9546). 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**
- Path `lang?/about` will match:
- `/:lang/about`
- `/about`
- Path `/multistep/:widget1?/widget2?/widget3?` will match:
- `/multistep`
- `/multistep/:widget1`
- `/multistep/:widget1/:widget2`
- `/multistep/:widget1/:widget2/:widget3`
**Optional Static Segment Example**
- Path `/home?` will match:
- `/`
- `/home`
- Path `/fr?/about` will match:
- `/about`
- `/fr/about`
### Minor Changes
- Allows optional routes and optional static segments ([#9650](https://github.com/remix-run/react-router/pull/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](https://github.com/remix-run/react-router/pull/9506))
```jsx
// 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](https://github.com/remix-run/react-router/pull/9721))
- Fix requests sent to revalidating loaders so they reflect a GET request ([#9660](https://github.com/remix-run/react-router/pull/9660))
- Fix issue with deeply nested optional segments ([#9727](https://github.com/remix-run/react-router/pull/9727))
- GET forms now expose a submission on the loading navigation ([#9695](https://github.com/remix-run/react-router/pull/9695))
- Fix error boundary tracking for multiple errors bubbling to the same boundary ([#9702](https://github.com/remix-run/react-router/pull/9702))
## 1.0.5
### Patch Changes
- Fix requests sent to revalidating loaders so they reflect a `GET` request ([#9680](https://github.com/remix-run/react-router/pull/9680))
- Remove `instanceof Response` checks in favor of `isResponse` ([#9690](https://github.com/remix-run/react-router/pull/9690))
- Fix `URL` creation in Cloudflare Pages or other non-browser-environments ([#9682](https://github.com/remix-run/react-router/pull/9682), [#9689](https://github.com/remix-run/react-router/pull/9689))
- Add `requestContext` support to static handler `query`/`queryRoute` ([#9696](https://github.com/remix-run/react-router/pull/9696))
- Note that the unstable API of `queryRoute(path, routeId)` has been changed to `queryRoute(path, { routeId, requestContext })`
## 1.0.4
### 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 you `loader`/`action` returns a value, and you may return `null` if you don't wish to return anything. ([#9511](https://github.com/remix-run/react-router/pull/9511))
- Properly handle redirects to external domains ([#9590](https://github.com/remix-run/react-router/pull/9590), [#9654](https://github.com/remix-run/react-router/pull/9654))
- Preserve the HTTP method on 307/308 redirects ([#9597](https://github.com/remix-run/react-router/pull/9597))
- Support `basename` in static data routers ([#9591](https://github.com/remix-run/react-router/pull/9591))
- Enhanced `ErrorResponse` bodies to contain more descriptive text in internal 403/404/405 scenarios
## 1.0.3
### Patch Changes
- Fix hrefs generated when using `createHashRouter` ([#9409](https://github.com/remix-run/react-router/pull/9409))
- fix encoding/matching issues with special chars ([#9477](https://github.com/remix-run/react-router/pull/9477), [#9496](https://github.com/remix-run/react-router/pull/9496))
- Support `basename` and relative routing in `loader`/`action` redirects ([#9447](https://github.com/remix-run/react-router/pull/9447))
- Ignore pathless layout routes when looking for proper submission `action` function ([#9455](https://github.com/remix-run/react-router/pull/9455))
- properly support `index` routes with a `path` in `useResolvedPath` ([#9486](https://github.com/remix-run/react-router/pull/9486))
- Add UMD build for `@remix-run/router` ([#9446](https://github.com/remix-run/react-router/pull/9446))
- fix `createURL` in local file execution in Firefox ([#9464](https://github.com/remix-run/react-router/pull/9464))
- Updates to `unstable_createStaticHandler` for incorporating into Remix ([#9482](https://github.com/remix-run/react-router/pull/9482), [#9465](https://github.com/remix-run/react-router/pull/9465))
## 1.0.2
### Patch Changes
- Reset `actionData` after a successful action redirect ([#9334](https://github.com/remix-run/react-router/pull/9334))
- Update `matchPath` to avoid false positives on dash-separated segments ([#9300](https://github.com/remix-run/react-router/pull/9300))
- If an index route has children, it will result in a runtime error. We have strengthened our `RouteObject`/`RouteProps` types to surface the error in TypeScript. ([#9366](https://github.com/remix-run/react-router/pull/9366))
## 1.0.1
### Patch Changes
- Preserve state from `initialEntries` ([#9288](https://github.com/remix-run/react-router/pull/9288))
- Preserve `?index` for fetcher get submissions to index routes ([#9312](https://github.com/remix-run/react-router/pull/9312))
## 1.0.0
This is the first stable release of `@remix-run/router`, which provides all the underlying routing and data loading/mutation logic for `react-router`. You should _not_ be using this package directly unless you are authoring a routing library similar to `react-router`.
