Kotlin
Come to the backend side we have Kotlin!
Ktor for backend development
With this session, you will learn how to setup a Kotlin Ktor project with some routes using the framework tools and features (Routing, DataConversion, ContentNegotiation...) and communicate with a sample Android app.
Let see how we can easily setup a Postgres database connection with Exposed, an ORM library for Kotlin and see how clean architecture can be a good choice for developping your brand new API.
We can even go further and see that we can actully share code from your backend application and your Android application (say hi to Swagger!).

In this talk, we’ll discuss what the Kotlin team is working on, the priorities we have, and the additions you can expect in the language. The JVM platform is evolving, and Kotlin is keeping up with the new features as they become available. This includes the features introduced by the upcoming Project Valhalla and JVM support for sealed classes and records. In this talk, we’ll discuss how these changes affect Kotlin as a language, and how the Kotlin team finds a balance between drawing on ...

Some tasks, like upgrading dependencies to the right versions, are still tedious and time consuming. There's also compatibility gotchas because of the lack of metadata. This talk will start with a mention of the different problems that come with dependency management in real-world projects. Then it'll show how the developer tool refreshVersions (MIT licensed) ...

Http4k is a lightweight HTTP library written in Kotlin that enables serving and consuming of HTTP services in a functional and testable way. Unlike many other libraries and frameworks which have complicated abstractions and workflows, http4k captures the essence of communication over HTTP with few simple concepts. In this session I will explain and demo the core concepts in http4k by live coding from scratch http server for noughts and crosses game.

Developing for multi-platform is picking up speed as the Kotlin Multi-Platform gets better with every release. That mostly means that shared logic is being written in Kotlin which can then be targeted to many target platforms. Up until recently it wasn't easy to develop UI for multiple platforms on the Desktop side. That is changing with the introduction of Compose for Desktop, which will allow building application UI for Linux, macOS and Windows. In this session you will get to understand what ...

Model-View-Intent is a simple architectural pattern in principle, but questions come up when you try to implement it yourself. We draw on our 2+ years of experience with orbit-mvi, our MVI library, to show best practices for using an MVI system in your application. How do you integrate with Android? What happens when you rotate your device? What about navigation or one-off events? How do you make the system type-safe? What about developer experience? If you’ve ever had similar questions come ...
