ktor VS kotlinx.serialization

In paralel Jetbrains has created a lot of KMP frameworks that are awesome. One of them is Ktor that helps "create asynchronous client and server applications."

Ktor, a powerful web framework built with Kotlin, offers a lightweight and flexible solution for building web applications. In this article, we will guide you through the process of creating a Ktor project manually using Gradle and SDKMAN!. By following the steps below, you'll have a basic Ktor project up and running in no time.

take a look at http4k and ktor for Kotlin specific frameworks Spring has first class support for Kotlin e.g. the following will give you reactive HTTP endpoints when using spring-webflux (this is what is use at work):

Ktor (Microservices framework by JetBrains)

For Android you should use a more mobile friendly framework like Retrofit or if you use Kotlin you can use the multi-platform Ktor library with it's client module

And last but not least, Ktor Client as our HTTP client. https://ktor.io/ It's a pretty amazing http client library and integrates well with Kotlinx serialization and Coroutines.

Kotlin is going to be great with almost every single JVM server. Spring works well with Kotlin, and is directly supported, but spring is also massive, very bloated. I recommend looking at https://github.com/ktorio/ktor which continues to serve all of my needs very well, integrates fantastically with Kotlin coroutines, and has very fast startup time and very good performance.

For the sake of the test, we use Ktor - the easiest way to do so is to use initializer.

I know you are looking for Spring Boot and/or Quarkus, but have you tried ktor. Just curios if you had a particular reason for choosing the other 2. Disclaimer: I haven't used ktor.

Have you tried this:? https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/serializers.md

Regardless, I followed the documentation to register List for polymorphic serialization and my static code analysis does not seem to be happy with it.

I think kotlinx.serialization might come close, but looks like custom Encoders and Decoders are still experimental.

This example will not work on a multiplatform project. you are using gson, gson runs only on jvm, you should use https://github.com/Kotlin/kotlinx.serialization for the json parsing

This is the issue to +1 https://github.com/Kotlin/kotlinx.serialization/issues/1931

Fun fact, kotlinx.serialization had a release just recently which makes it come with some bundled proguard rules to make this experience easier. Yes you'll still have issues if you're using things via reflection and try to serialize things that proguard deemed unused and removed them, but it's a step forward https://github.com/Kotlin/kotlinx.serialization/releases/tag/v1.5.0-RC

Kotlin Serialization

Kotlin Serialization is also a newer option, but doesn't have as much traction.
