Optional language param slug

[imujo]

Hi everyone!

I'm looking to add an optional language param that's available in all my routes. If the user isn't logged in, the language would be the param language. However, if the user is logged in, the page language would be the language from their user settings. I'm hoping for the following URL structure:

/$lang/about when not logged in
/about when logged in

I saw another discussion (#146) about optional params where the conclusion was to create two routes, one with the param and one without. But that wouldn't be very clean for this use case since I'd have to duplicate all routes in my app.

I had an idea to put all the routes in a separate array and pass them as children for both the "languageWrapperRoute" and the root route:

const routes = [
    dashboardRoute,
    profileRoute.addChildren([profileIndexRoute, editProfileRoute]),
    ...
];

const routeTree = rootRoute.addChildren([
   languageWrapperRoute.addChildren([routes]),
   ...routes
]);

But that doesn't work because all routes need to have getParentRoute which would be different depending on if the route is in the languageWrapperRoute children, on rootRoute children.

Any ideas?

Have you been able to find a solution for that?
