HI,
We are using kotlin with ktor server side.
Is there a simple way to schedule a task? In spring I just use @scheduler annotation.
any examples?

You could use Arrow Fx Schedule, and Coroutines.

[simon.vergauwen]

fun Application.task(): Job = launch {
   Schedule.spaced<Unit>(1.minutes).repeat {
     // Run task
   }
}

It has a wide set of operators for building complex Schedules. https://arrow-kt.io/docs/apidocs/arrow-fx-coroutines/arrow.fx.coroutines/-schedule/

I'll check. thx

Do I have to wrap it in run blocking?

runBlocking {
            Schedule.spaced<Unit>(5.minutes).repeat {
                <http://log.info|log.info> { "here" }
            }
        }

Is it good practice?

You should use Application from Ktor which is a CoroutineScope, and then you can launch the Job with the same lifecycle as your Ktor server.

[simon.vergauwen]

fun Application.task(): Job = launch {
   Schedule.spaced<Unit>(1.minutes).repeat {
     // Run task
   }
}

Application here is Ktor Application
