KotlinConf App

This is the official KotlinConf App! We hope you enjoy(ed) the conference and sessions. This repository contains the source code of the application.

All pieces of the application are implemented in Kotlin. Backend, frontend and mobile apps are Kotlin applications. Yes, Kotlin is powering all parts of the story. Did I already say that? Okay, let's get to the details:

Server

KotlinConf App is connecting to the server running in the cloud to get information about sessions, speakers, favorites and votes. It is developed using Ktor, an asynchronous Kotlin web framework.

The server polls Sessionize service, which is used for planning the conference. Once in a while, it connects to APIs to get the latest information about sessions, speakers, and timeline. It then augments and republishes this information for clients to consume. It also provides a couple of extra APIs to save your favorites and accumulate votes.

iOS, Android, Browser and Desktop Applications

All applications are developed within a single codebase using Kotlin Multiplatform technology. The UI is implemented using Compose Multiplatform UI framework.
