Why are the router extensions deprecated?

Since I upgraded to latest versions of Kotlin wrappers, my usages of router extensions are marked as deprecated. The ReplaceWith is broken so I had to manually replace the function calls.

What is the reason for the deprecation? Is there an alternative to using the raw component directly?

It really looks awkward now. I used to have this:

fun RBuilder.application() = hashRouter {
    errorDialog()
    switch {
        route(Route.GAME_BROWSER.path) { gameBrowser() }
        route(Route.GAME.path) { gameScene() }
        route(Route.LOBBY.path) { lobby() }
        route(Route.HOME.path, exact = true) { home() }
        redirect(from = "*", to = "/")
    }
}

And now I have to replace with:

fun RBuilder.application() = HashRouter {
    errorDialog()
    Switch {
        Route {
            attrs.path = arrayOf(Route.GAME_BROWSER.path)
            gameBrowser()
        }
        Route {
            attrs.path = arrayOf(Route.GAME.path)
            gameScene()
        }
        Route {
            attrs.path = arrayOf(Route.LOBBY.path)
            lobby()
        }
        Route {
            attrs.path = arrayOf(Route.HOME.path)
            home()
        }
        Redirect {
            attrs {
                from = "*"
                to = "/"
            }
        }
    }
}

Thanks for getting back to me @sgrishchenko 👍

I totally understand, maintaining and extending those functions as ReactRouter evolves is a lot of work. I think for the time being we’ll have to copy the deprecated functions we are using into our codebase and we can maintain them as needed.

Thanks also for sharing kotlin-react-function project, I’ll have a look at it later.

@francos you absolutely right, there is such a problem now, but this problem is present for each component in current DSL implementation: there is not way to set all props for component safely. We, maintainers, are thinking about solution for it, but we want to provide general solution. I think it does not fare to make wrapper for Router more complex and to add a lot of boilerplate code there because of DSL problems.

At the same time we cant provide solution right now. Probable solution is compiler plugin, but there is not appropriate API for compiler plugin in Legacy compiler and we have to provide compatibility for both IR and Legacy compilers until IR compilers is stable.

As temporary solution I can offer you to check this project, may be it will help you
