React Router 7 GetLoadContext not available when using unstable_middleware #514
Description
``The getLoadContext function allows us to pass really anything to the context for usage in our React router loaders. The new unstable_middlewares flag means that getLoadContext doesn't return AppLoadContext, it returns an unstable_InitialContext which is a Map<unstable_RouterContext, unknown>.
THat is my understanding on the update. And my idea what it should be like, but basically a map of those contexts should be returned.
type AdapterContextType = {
session: FastifySessionObject;
};
export const adapterContext = unstable_createContext<AdapterContextType>();
await app.register(reactRouterFastify, {
getLoadContext(request: FastifyRequest): unstable_InitialContext {
const map = new Map<unstable_RouterContext, unknown>();
map.set(adapterContext, { session: request.session });
return map;
},
});
Essentially this code is used to pass the session to rr7, consoleing the context provides unstable_RouterContextProvider {}, and doing a context.get(adapterContext) provides no value for this context.
Perhaps I'm not understanding the usage, I had tried this with the middlewares in rr7 but had no values to get htere too.
I would appreciate this very much if you could look into this.
