Ok, thanks )) latest ver

Started a call.

@francis please do not initiate calls in public channels.

hi, trying to get start building a mocking api with ktor. So far so good, but their is missing pieces in the documentation. If you follow

Setting up a Gradle Build

than continue on with

Guide - How to create an API using ktor

It will not work, because the setup is incomplete

@Raghavendra Rao K Use of !! is not recommended as you suggested in your article, rather use ?.

Is !! not recommended anyways?

there are perfectly fine valid cases where !! is needed; it’s not necessarily a code smell

But still you can avoid

!!

in most cases

How do you guys handler exceptions in your handler? is something like this enough?

class ValidateUserHandler : RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {

    private val logger = Logger.getLogger(ValidateUserHandler::class.java)

    override fun handleRequest(input: APIGatewayProxyRequestEvent?, context: Context?): APIGatewayProxyResponseEvent {
        try {
            val token: String? by lazy {
                if (input!!.headers["Authorization"]?.startsWith("Bearer ") == true) {
                    val token = input.headers["Authorization"]?.substring("Bearer ".length)?.trim()
                    if (!token.isNullOrEmpty()) token else null
                } else {
                    null
                }
            }
            
            val authoriserResult = validateToken(token!!)

            return when (authoriserResult.authorised) {
                true -> {
                    APIGatewayProxyResponseEvent()
                            .withBody("OK")
                            .withStatusCode(200)
                }
                else -> {
                    APIGatewayProxyResponseEvent()
                            .withBody("Unauthorized}")
                            .withStatusCode(401)
                }
            }
        } catch (ex: Exception) {
            logger.error("Unexpected error occured: $ex", ex)
            return APIGatewayProxyResponseEvent()
                    .withBody("System error")
                    .withStatusCode(500)
        }
    }
}

i don't know what framework this is, but a lot of frameworks support exception-mappers

so you can just throw instead of try/catch in every handler

That's AWS Lambda.

📣 If you are contributing to any server framework (Kotlin, Java or whatever) and planning to come to #kotlinconf please send me a DM.

In ruby, there is a library for creating fixtures, for testing, called factory_bot, https://github.com/thoughtbot/factory_bot, I want to know If there is any similar library for kotlin, for creating test fixtures.

I'm getting an error from kapt when building my project:

java.lang.AssertionError: annotation tree hasn't been attributed yet: @kotlin.Metadata(mv = {1, 1, 13}, bv = {1, 0, 3}, k = 1, d1 ... (omitted for brevity)

It seems to go away when I disable

correctErrorTypes

, but then

dagger

doesn't work, so I can't do that.

is there something I'm doing wrong? I can post build files, but the project is pretty complex and I don't know where to start trimming stuff out

updated to Java 10, which gave much better error output looks like I had some compile errors that were leading to bad Java code in kapt stubs, and kapt wasn't catching that

I have written a detailed status update about Spring Fu and Kofu, its Kotlin DSL. See you at Kotlinconf to discuss about that. https://twitter.com/sdeleuze/status/1047126137376247808

Now I have to update my slides 😉

Hi there! I have a question about the router in ktor. Is it possible to match routes only for a certain host-name? What i am trying to achieve is something like api.example.com and admin.example.com and each of them should react differently, but all is running in the same codebase. Is there a way to do this OR is this generally a bad approach? Is there some other strategy? Maybe running the server twice on different ports with different main module etc ... Thanks in advance.

why would you compare them?

@Edgars there is a tone of options. You could either render stuff from tje server using templates or use a ja framework like angular react or vue

Is there anything Kotlin-based? 😄

kotlin.js 🙂

Interesting. Thanks! 🙂

I'd suggest using bootstrap or something similar like semantic ui for the UI

that way you don't have to bother about the design part

you can use

kotlinx.html

to generate html
