v6.8.0

What's Changed

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 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)
• react-router-dom-v5-compat - Fix SSR useLayoutEffect console.error when using CompatRouter (#9820)

v6.6.0

What's Changed

Patch Changes

• Support uppercase <Form method> and useSubmit method values (#9664)

• Fix explicit replace on submissions and PUSH on submission to new paths (#9734)

Full Changelog: https://github.com/remix-run/react-router/compare/[email protected]@6.6.0

v6.5.0

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: https://github.com/remix-run/react-router/compare/[email protected]@6.5.0

v6.4.5

What's Changed

• 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: https://github.com/remix-run/react-router/compare/[email protected]@6.4.5

v6.4.4

What's Changed

• 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)
• Updated dependencies:
  • @remix-run/[email protected]
  • [email protected]

v6.4.3

What's Changed

• Generate correct <a href> values when using createHashRouter (#9409)
• Better handle encoding/matching with special characters in URLs and route paths (#9477, #9496)
• Generate correct formAction pathnames when an index route also has a path (#9486)
