I am trying to run a Ktor server without using an `application.conf`file, but I find no way of configuring the `rootPath`when using

embeddedServer

. This snippet compiles, but does not affect the root path - the application still uses

/

as root path: fun main() { embeddedServer( Netty, port = 8097, configure = { applicationEngineEnvironment { rootPath = "/api" } }, module = Application::main ).start(wait = true) } Does anyone know it it's possible to configure

rootPath

when using

embeddedServer?

The

rootPath

property is only applied for the servlet containers. What behavior do you expect with the above code?

Well, when running through EngineMain, I can configure `rootPath`to "/api", and all endpoint paths within my application will have the prefix "/api", i.e. I can specify a route "/users", and it will be available for requests at "/api/users" . I wanted to do the same, but with embeddedServer.

If am am getting you right @strindberg, to achieve that you need to do something like this routing { route("/users"){ post("/add") { val requestUser = call.receive<User>() val userId = UserDao.addUser(requestUser.name) val newUser = User(userId, requestUser.name) call.respond(HttpStatusCode.Created, newUser) } I hope this helps

Thank you David, but my problem is not with the implementation of my route. What I want to achieve is for all rest paths to have the prefix "/api", without having to specify if for every endpoint. This can be achieved when running through EngineMain, configuring it in

application.conf

, but I can find no way of doing the same kind of configuration in EmbeddedServer.

I now understand you @strindberg, but from my side have not tried implementing that before and I should try but in the meantime, I hope you will find someone who has a solution, thanks.

@strindberg the problem is that you've configured the server incorrectly. Here is a correct way:

embeddedServer(
    Netty,
    applicationEngineEnvironment {
        rootPath = "/api"
        connector {
            port = 8097
        }
        module(Application::main)
    }
).start(wait = true)

@Aleksei Tirman [JB] Thank you! That solved my problem.
