Haxelib vs Kotlin/JS

Haxelib is the library manager included with Haxe distributions. It connects to a central repository for finding, installing, and sharing Haxe libraries on Windows, macOS, and Linux, with API access. The command line installs the latest release or a specified version, resolves dependencies from HXML files, and supports offline installation. Search matches project names or descriptions, while the info command displays ownership, licensing, descriptions, websites, tags, versions, and release notes. Developers can submit ZIP archives or directories, use Git or Mercurial repositories, and create local repositories from project files. Installed libraries can be exposed to the Haxe compiler with --library or -L. Haxelib can use an HTTP proxy or a custom server. Libraries are distributed as source by default. The public HaxeFoundation repository is MIT licensed, and community links include GitHub, bug reports, Stack Overflow, forums, Discord, and Gitter. All libraries are free.

Kotlin/JS is a Kotlin compiler target that converts Kotlin code, the Kotlin standard library, and compatible dependencies into JavaScript. Projects can target browsers or Node.js, including server-side and serverless applications. It supports ES5, ES2015, and ES2020 output, as well as ESM, CommonJS, UMD, and AMD modules. Projects use the Kotlin Multiplatform Gradle plugin for configuration, bundling, and JavaScript dependencies from npm. Kotlin/JS can share logic between web frontends and JVM backends, or across Android, iOS, and web clients. Kotlin wrappers are available for React and other JavaScript frameworks, including React Redux, React Router, and styled-components. Browser tests can use Karma or an experimental browser testing DSL; Node.js projects use Mocha. The documentation notes that Karma is deprecated and is not expected to receive new features or bug fixes. The Gradle plugin generates JavaScript source maps for builds. Kotlin/JS is open source and free at free, and is listed for Linux, macOS, web, and Windows.
