Hi, is it possible to get factory pattern with Ktor DI?

It's generally made for singletons only, but you can use factory instances or lambdas like:

dependencies {
    provide<() -> GreetingService> { ::GreetingServiceImpl }
}

val service: () -> GreetingService = dependencies.resolve()
assertEquals(HELLO, service().hello())

Hmm.. doesn't work for me

[Bruce Hamilton]

oh there's args there, so it'd be like

provide<() -> RuBot> {{ RuBot(resolve(), resolve(), resolve()....) }}

which is not so attractive

[Bruce Hamilton]

better to create a factory type in these cases

[lc]

this trick worked

[Bruce Hamilton]

it'll still use a singleton instance in that case though...
