Got rid of the duplication here - <Route>
props are now just RouteObject
equivalents that expect ReactNode
children instead of ReactElement
children

These are the new foundation of the types. They get extended in react-router with element
/errorElement
and then again in RouteProps
to change children from RouteObject
to ReactNode

LGTM. Just had one small nit about code readability. Thanks 🙏

Just a nit here: but I much prefer to avoid using Omit
if we can and avoid the mental overhead of looking up that interface when reading through this code. Listing out all properties explicitly means it's all right here in front of me.

@brophdawg11 I'm a bit late to the party, but better late than never: while testing the prerelease for #9352 I noticed this property had suddenly become required. I'm assuming this might be unintentional? 😊 Same goes for NonIndexRouteObject
below.

Oh thank you! Yes that's definitely a typo :)
Fixes a type mismatch caused by change remix-run/react-router#9366 in react-router code.

Fixes a type mismatch caused by change remix-run/react-router#9366 in react-router code. Have to use any because of typing changes in the above PR, since we can't be backwards compatible with both versions very easily. Co-authored-by: Philip Atkinson <[email protected]>

why children?: undefined;
, maybe we can remove this line?
Based off #9343 and extends route type safety downwards to
@remix-run/router
and upwards to<Route>
prop typings. This provides type-safety for JSX-defined route trees:Note: screenshots are slightly outdated, spoke to @mjackson and it is valid to have a path on index routes, and serves as a way to separate index from layout routes. This PR has been update to only prevent
index
+children
.As well as manually defined route trees:
This also adds a few invariants and associated tests to check for these invalid conditions:
flattenRoutes
(lowest common denominator)createRoutesFromChildren
(always used inBrowserRouter
, sometimes used inRouterProvider
)convertRoutesToDataRoutes
(always used inRouterProvider
)
