sorry for off-topic question, do we need billing enabled for deploying web app to gcloud i just want to try out some sdks

[Coroutines] Hello, may some one help me? I'm studying about Kotlin coroutines, and I have a question which couldn't find any clear answer. The question is: why do I need to specify the coroutine context, can't I just use the default one? And how can I create a custom context, my custom thread pool? (Talking about backend) Thanks!

#ktor Hey guys.

#ktor I have a web REST API which runs on Netty. I managed to successfully deploy it to Heroku. I expected the Heroku's Java buildpack to automatically detect Ktor framework. I tried executing the command heroku ps:scale web=1 to at least get one instance of the app running, which resulted me to getting the error Couldn't find that process type. Anyone who have experienced this and what did they do?

@Kingmoses does the app have a

Procfile

?

Hello again I have run into a small issue. I want to serialize my model using GSON but i get stuck with an StackOverflow so to solve this i wanted to try using expose annotations which do not work “This Annotation is not applicable to target ’member property with delegate”

@Expose(true)
     var name by Table.name

Meaning that i cannot specify what to serialize and what to not serialize. The way i have solved this now is to use a Data Class along side my model class, which is a pain because then i would have to have tree objects for one table. There must be a better way!

Tried ktor, wasabi and even nanohttp but no luck

sunhttp does not work on native, it’s java only

Before we have multiplatform IO/socket abstraction and Ktor is JVM only, the simplest way to do that is just use some C http server library for native and probably write some idiomatic Kotlin wrapper for this library.

@here I need to ramp up quickly on idiomatic Kotlin patterns using coroutines with both blocking and non-blocking I/O. Any pointers to the good resources? Thanks.

when i hit server i am getting java.lang.IllegalArgumentException: Parameter specified as non-null is null: method mypkg.repository.data.Department.<init>, parameter name at mypkg.repository.data.Department.<init>(Department.kt) ~[classes/:na] at mypkg.repository.data.Department.<init>(Department.kt:9) ~[classes/:na] at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) ~[na:1.8.0_131] at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) ~[na:1.8.0_131] at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) ~[na:1.8.0_131] at java.lang.reflect.Constructor.newInstance(Constructor.java:423) ~[na:1.8.0_131]

and how do you feel about it?

Please is there any internship programme u know for web dev, please info me to join

Could someone suggest me some Kotlin frameworks/things for making a website? I want to build a run of the mill simple webpage with login and a database, for which I'd usually use PHP, but I'd like to not use PHP. How do I do these things in Kotlin? Thank you.

@sdeleuze have you tried working with https://github.com/JetBrains/Exposed instead of the jpa annotations?

Also, one issue I ran into with the data classes is they wanted private constructors, did you not run into the same thing?

Slides from a short presentation I did at a local Kotlin meetup comparing different Kotlin framworks: https://drive.google.com/open?id=1Y4H-7z5mdVxpIKwgbe2dzBjL7ieq-rBU Surprisingly, some of the audience wanted a deeper dive into Vert.x's Kotlin support...

hi，do exposed support Chinese string？

Hello everybody, how do you guys handle the crud save from json problem? When you have a few relations and business rules for your beans/models things starts to become quite nasty. This is the oldest business case in the book so how do people go about this? In kotlin?

http://arhipov.blogspot.ru/2017/08/xrebel-for-standalone-apps-with.html You can use #ktor with embedded Jetty.

interesting article. I wonder how far you could get with AOT compilation of Kotlin JVM code e.g. with Graal

Or even Kotlin/js

I am new to kotlin, our team is thinking of utilizing kotlin for writing one of the service for our project. Is Ktor a good framework to go with or there are any better alternatives? This is just for a specific feature (1 or 2 endpoints) will talk to dynamodb to update/read json file.

hi guys is there a way to have file listing with ktor? I mean serving a static page with all the clickable files in that dir?

hey guys! I'm trying out spring boot and Kotlin - my preference for Kotlin projects is generally maven, but I was wondering if you have any preferences on maven vs. gradle for server-side experiences with Kotlin?

I'll check both out! I really like docker, but I haven't heard of H2 before.

If you're using a SQL database I think jOOQ is solid. You can see how to use it with kotlin in https://bitbucket.org/marshallpierce/ktor-demo/src/master/.

I suggest at least checking “Single Instance”.
