Ktor uses plugins to give you fine-grained control over the functionality included in your application. Until now, third-party plugins were managed differently from those provided by the Ktor team. This was a barrier to growth for the Ktor ecosystem. Earlier this month, in the Ktor 2024 product roadmap, we announced our Ktor Plugin Registry. This registry is now available. It enables the submission of community-based plugins to the Ktor team, categorizes plugins for easy searching, and provides users with essential documentation. Introduction At the moment you can build a Ktor project via the ..read more

Interactively exploring and visualizing data allows users to uncover hidden patterns, trends, and relationships that may not be immediately apparent through static analysis. This instant feedback allows users to quickly validate their assumptions, identify outliers or anomalies, and adjust their analyses. Kotlin Notebook is a convenient tool for exploring data in IntelliJ IDEA. It uses the Kotlin kernel to execute snippets of Kotlin code in cells and then renders the data in the editor. It integrates libraries such as Kotlin DataFrame for data processing and Kandy for chart creation, thus simp ..read more

Since the Ktor Roadmap for 2024 was published there have been a lot of questions regarding Dependency Injection (DI). Specifically how Ktor will be changed to support DI, and to integrate existing DI frameworks. This work is still in its early stages, but we would like to clarify our intentions and invite feedback. First and foremost, we would stress that: There will never be any requirement to use a DI framework with Ktor. Ktor itself will never include a DI framework as part of its design. The proposed feature is solely for users who wish to combine DI with their Ktor services. We want to ..read more
