v6.16.0

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)
  • 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)
