Ktor is a framework to easily build connected applications – web applications, HTTP services, mobile and browser applications. Modern connected applications need to be asynchronous to provide the best experience to users, and Kotlin coroutines provide awesome facilities to do it in an easy and straightforward way.
The goal of Ktor is to provide an end-to-end multiplatform application framework for connected applications. Currently, JVM client and server scenarios are supported, as well as JavaScript, iOS and Android clients, and we are working on bringing server facilities to native environments, and client facilities to other native targets.
This is free and open source software.
Key Features
- Coroutines – built from the ground up using Kotlin and Coroutines. You get to use a concise, multiplatform language, as well as the power of asynchronous programming with an intuitive imperative flow.
- Lightweight and flexible – use only what you need, and to structure your application the way you need it. In addition you can also extend Ktor with your own plugin very easily.
- Asynchronous – pipeline machinery and API are utilising Kotlin coroutines to provide easy-to-use asynchronous programming model without making it too cumbersome. All host implementations are using asynchronous I/O facilities to avoid thread blocking.
