Minor Changes

New Fetcher APIs

Per this RFC, we've introduced some new APIs that give you more granular control over your fetcher behaviors. (#10960)

• 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 useSumbit 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. (#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() 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

6.21.0

Minor Changes

• Add a new future.v7_relativeSplatPath flag to implement a breaking bug fix to relative routing when inside a splat route. (#11087)

  This fix was originally added in #10983 and was later reverted in #11078 because it was determined that a large number of existing applications were relying on the buggy behavior (see #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:

  <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>:

  function Dashboard() {
    return (
      <div>
