It’s been a while since we first introduced our mascot, but it is back and it has a name now – Kodee! With your feedback in mind, we have redesigned our mascot to create an approachable and […]

“A very important delegate from Kotlin stdlib is observable from the Delegates object. It makes the property behave like a regular one and specifies a function that'll be executed whenever the property setter is called.” This is the introduction to the latest article written by @marcinmoskala 👉🏻 https://kt.academy/article/ak-observable-vetoable

Hello, everyone! I am really happy to share a project that I've been working on over the past few months: River-Kt. It's a collection of extension functions and enterprise integrations for Kotlin's Flow and coroutines. Drawing inspiration from Alpakka and Apache Camel, River-Kt leverages the features of Flow to provide an easy way to build integrations across multiple protocols and services, such as HTTP, AWS (SQS, SNS, S3, etc.), AMQP, Debezium, JSON, Files, and others. Please note that River-Kt is currently in the alpha stage, which means that certain aspects may change in the near future. Some connectors might not be stable yet, and the project is still gathering feedback before an official initial release. While the project currently lacks comprehensive "end-to-end" documentation, the existing kdocs are relatively informative. If you're familiar with the basics of Flow and reactive streams, you'll find them to be a helpful starting point. I would greatly appreciate any feedback you may have on this project, including suggestions for improvements or fixes. You can find the GitHub repository here: https://github.com/River-Kt/river And the website with the kdoc is available at: https://www.river-kt.com/ Thank you for your time and consideration!

Hello everyone, I made I made a compose multiplatform rich text editor library that makes is too easy to create a fully customizable rich text editor. Give it a try 😄 https://github.com/MohamedRejeb/Compose-Rich-Editor

Collection builders make it easy to build a collection's contents programmatically, without allowing changes to the collection after it's been built. In this video, we'll look at collection builders... and we'll even poke around with immutable collections. Hope you like it! 🙂

We continue developing our Elasticsearch client: https://anti-social.github.io/elasticmagic-kt/latest/. It is the only typed client for Elasticsearch I know (it is not possible to match integer field with a string). Finally we have been using it in production for several months. Version

0.0.20

contains a lot of changes and improvements: • implemented count API • implemented delete and update by query APIs • implemented tasks API • support for runtime mappings • facet filters for attributes •

has_parent

,

has_child

queries • immutable query nodes that might be changed by replacing • transport request trackers for metrics, logging, etc • YAML serialization An article how we cook facet filters for attributes was written: https://github.com/anti-social/elasticmagic-kt/wiki/Cooking-the-Facet-Filters

Configuring Kotlin Applications and Builds

Finally releases available on Maven Central. "God, maven publication is a pain!" I hope one day there is a simple repository and publication to KLIB instead 🙌 https://github.com/programadorthi/kotlin-routing/releases

New release of Ktorfit, it's now using Ktor Clients 2.3.0 https://github.com/Foso/Ktorfit

Maps-kt is published in our Space repository (only available with manual repository definition for now, but I will publish it on central soon): https://github.com/SciProgCentre/maps-kt/releases/tag/v0.2.2 Maps-kt is a compose-multiplatform library that includes stand-alone implementation of map and scheme rendering together with utilities to work with map objects and trajectories. For now it only works for desktop target, but android and web targets are easy to add. The package also includes a separate library called

trajectory-kt

, which is based on @ESchouten contribution to KMath (we decided to move it to another project for faster release development and release cycle. It introduces primitives to work with 2D trajectories and path optimization (Dubins path and a unique obstacle avoidance algorithm designed in SPC). The library is not very well documented, so contributions are welcome. We also use it in our commercial products, so some features (like global trajectory optimization) are not included. Feel free to discuss it in #science.

So I went ahead and made a video out of the amazing tutorial by Jetbrains about building a full stack web app with kotlin and react (the shopping list tutorial)

“How can

Map

be a delegate? To be able to use an object as a read-only property delegate, this object must have a

getValue

function. For

Map

, it is defined as…” To find out the answer check this article by @marcinmoskala 👇 https://kt.academy/article/ak-map-delegate
