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.

yes, it’s called

AuthenticationChecked
