NodeJS Toolkit is currently in beta testing and will be released in Q1 2018.
NodeJS Toolkit works similar to the PHP Toolkit, providing the same full platform features but taking advantage of NodeJS possibilities and allowing you to use any standard NPM packages to extend the functionality and connect to third party systems. One of the big advantages with NodeJS toolkit is its more asynchronous nature, which will speed up some of the backend operations.
You can mix in your application existing actions built with PHP also, so things like login, registration, settings, user profiles and many other existing actions, can simply be added through the web admin. This will radically speed up your application development.
The NodeJS version includes also the Appzio UI Kit.
