Hello, I'm trying to develop SPA SSR with Ktor by using existing features of

singePageApplication()

, but with a server generated

index.html

. I've created this configuration:

Copy code

routing {
        get("/index.html") {
            call.respondText(
                "<html><head><title>Custom index.html</title></head><body></body></html>",
                ContentType.Text.Html
            )
        }
        singlePageApplication {
            defaultPage = "index.html"
            filesPath = "/assets"
            useResources = true
        }
    }

but unfortunately it doesn't work (not existing urls are redirected to

/assets/index.html

file instead of my

/index.html

endpoint). Can I somehow do this with a simple configuration or do I have to implement the whole thing from scratch?

I don't see an easy way to do it. Can you describe the logic of the

/index.html

route's handler in your application?

I would need access to the requested URL. Then call an external API and return some html code.

I suggest filing a feature request to support your use case.

After some experiments and digging in Ktor sources I've come up with this:

Copy code

routing {
    get("/index.html") {
        call.respondText("Hello, world!", ContentType.Text.Plain)
    }
    singlePageApplication {
        defaultPage = "NOT_EXISTING_RESOURCE"
        filesPath = "/assets"
        useResources = true
    }
    route("/") {
        route("{static-content-path-parameter...}") { // !!! Important name copied from Ktor sources
            get {
                call.respondText("Hello, world!", ContentType.Text.Plain)
            }
        }
    }
}

It seems to do exactly what I want.
