I'm updating an plugin for authorization I made for Ktor 1.6 to the new 2.0.0 Plugin concept, but I am running into an issue I don't understand. Say I want plugin Foo to run after the existing Authentication plugin. When I try

val Foo = createApplicationPlugin("Foo") {
    after(Authentication) {

    }
}

the line starting with after generates a compiler error:

Type mismatch.
Required: io.ktor.server.application.Plugin<*, *, PluginInstance>
Found: io.ktor.server.auth.Authentication.Plugin

The supertype of io.ktor.server.auth.Authentication.Plugin is ApplicationPlugin<Application, Configuration, Authentication> . Now I am not strong on generics, but I guess this is indeed not a subtype of the required io.ktor.server.application.Plugin<*, *, PluginInstance> (Is this the same issue as you talk about here, @hhariri?)

Is there any way to make my plugin run after the Authentication plugin?

Oh, really sorry, but I haven’t seen this mention. We are reworking new plugins API and we will drop after /`before` blocks. Instead of them we will introduce hooks. Authentication plugin will provide a hook that you can use to run after it.

Ah great, thanks for the reply! I'll sit tight for now and wait for this to come out.

Hi @Rustam Siniukov, congrats on shipping 2.0! I have been looking in the documentation for the hook you mentioned, but no luck so far. Has it been implemented?

[Rustam Siniukov]

yes, it’s called AuthenticationChecked
