I am trying to setup test coverage on my spring-boot project with gradle. I have used `kotlintest`(https://github.com/kotlintest/kotlintest) as the testing framework. Any recommendations?? Thanks in advance.

Hello all I am looking for a big project (sources) - full stack? On the basis of this project I would like to model myself and create my own

I'm try to write a continuation that I can "call-back/continue" some time later at my chooesing. I'm trying to await on a CompletableFuture, but that doesn't seem to be pausing that "green thread". await it just returning a non-completed future. Anyone know what the trick is? Lots of docs on how to use yield & delay, but none on how to write you own.

I have talk about that with several people at Kotlinconf, but Pivotal has announced 2 weeks ago R2DBC which is an initiative to provide Reactive SQL drivers, with a PostgreSQL driver already available, and others likely to be later. I am working on Spring side to provide Coroutines API on top of that but https://github.com/r2dbc/r2dbc-client is only based on Reactor and could be easily exposed with a Coroutines API using https://github.com/Kotlin/kotlinx.coroutines/tree/master/reactive/kotlinx-coroutines-reactor for other Kotlin server side ecosystems. With https://github.com/Kotlin/kotlinx.coroutines/issues/284 it will even be possible to manage async transactions, and with https://github.com/Kotlin/kotlinx.coroutines/issues/254 you will be able to receive rows as streams.

See #ktor btw but I'd probably run one service that listens on two ports for that case... it's basically vhosting but less of a pain (and easier to manage in local dev too -- no /etc/hosts modifications etc)

Hello! Has someone had a chance to compare Ktor and ExpressJS? Their approaches seem to be very similar.

Hello! I have pretty much 0 (valuable) web dev experience. I don't know much about back- and front-end frameworks and whatnot. So pardon me if this is a stupid question, but how would I go about making a good-looking website using Ktor? From what I gather, Ktor is what I want for, say, routing, business logic, etc. What do I need to make a pretty front-end?

Anyone tried http://www.vaadinonkotlin.eu/ ?

Hello everyone! I've been looking for an answer abot KTOR but can't find it anywhere: is KTOR a jvm-based server? I mean, I need a jvm to run it? (sorry if this is a dumb question, but server development is not my area).

Show KN: I am trying to write a simple

lwan

(a web framework in C) wrapper in #kotlin-native. Any suggestion for how you design a web framework/want to structure your api?

Hi all as we know jdk11 is not free,so can we use kotlin instead of java?

that’s not kotlin specific there should be no builder nor no new object instanciation in your class all dependencies should be (constructor-)injected

From the creators of Grails: http://micronaut.io

I have just created a #micronaut channel

Has anyone tried implementing json responses using

KTOR

? Documentation is not clear!

I found coroutine in Kotlin 1.3 is using

DefaultScheduler

for it's default dispatcher, but it extend from the

ExperimentalCoroutineDispatcher

and not the

CommonPool

before. Is it suggested to use on online env?

what I'm missing?

@Jeff Gulbronson not really, I just found koin in my researchs and try to use that

is most of the code in a common module?

It means the

@Id

should be

var

and nullable type? I should every time write

val id = entity.id!!

in this case. I hope JBoss team will do improvement for Kotlin in the future (for Hibernate).

if you aren’t deathly afraid of writing a bit of SQL

📣 If you need arguments to try #ktor, here is one: https://www.thoughtworks.com/radar/languages-and-frameworks

Has anyone found an existing GraphQL library that utilizes coroutines?

Hi everybody, I have a project based on #ktor v1.0.0-beta-4. It’s an API, exposing a big catalog (35 Mo). I am planning to bring this catalog into pieces later on but right now, it goes to production as this, in the form of a big String. I have some memory performance issues and I try to fix those issues. My App has the same configuration than during the Dev. I am looking for a way to have 2 separate configuration, one for dev and one for prod. I have read the documentation (https://ktor.io/servers/configuration/environments.html) but I can’t find a way to disable the autoreload conf I have set up in my app for dev purpose. Do you know how to do it ?

Hey folks, I’m working on a Ktor application that acts like a gateway between our app and the backend. Its only purpose is to combine multiple http requests into one for the app. In general communication between backend services is wrapped in Hystrix commands. I’m now wondering if this is also feasable for my Ktor service. The call to the other services should happen in parallel and I wanted to leverage coroutines for that, but when I now use Hystrix inside a Coroutine I end up starting a thread again, right? Do I have to use something like the Ktor client, which implements suspending functions around the http requests, or would it be fine (aka performant) to use Hystrix and just start a thread? Or is there maybe even a Hystrix alternative I could use in this particular case?

Hey guys. Would anyone here be interested in trading React mentoring for Kontlin mentoring? I’m looking to get up to speed on building full fledged API’s with Kotlin, preferably Ktor.
