Ktor 1.3 was released recently, and we’re happy to share the details with you in this blog post. Ktor consists of two parts: the server engine and a flexible asynchronous HTTP client. The current release focuses mainly on the HTTP client. Here you can find the complete changelog for this release. The client is a multiplatform library that supports JVM, JS, Android, and iOS and is now often used in cross-platform mobile applications. Our main goal for the next releases is to make the server engine multiplatform, too. The other areas we’re going to work on are: Improving integration w

As we work on Kotlin, we implement many features that help build idiomatic and high-performing APIs. We've been dreaming of seeing a Web framework that utilizes these features to the max. Today, we can finally say we've built that kind of framework! Please welcome Ktor, which has just reached 1.0. Ktor is a Kotlin framework for building asynchronous servers and clients in connected systems. It is being created by the Kotlin team, and as such, it takes full advantage of the language in order to provide a great developer experience and excellent runtime performance. Ktor is built from the gr

With Kotlin 1.1, targeting JavaScript in the Kotlin compiler has officially reached production-ready status. Of course, having compiler support is not enough to be able to solve real-life problems, so we continue our work on integrating Kotlin into the larger JavaScript ecosystem. Today, we'd like to present two new projects: a Gradle plugin integrating Kotlin with npm, webpack and karma, and a full-stack application sample with a Kotlin/JVM backend and a Kotlin/JS frontend built with React. Kotlin Frontend Plugin The Kotlin frontend plugin allows you to build and deploy a Kotlin frontend a
