JsScript AddOn

I can’t find my way around Python and find the problems I try to solve too complex to handle in UI Automations and yaml scripts. My problem doesn’t fit Node-Red either and I find myself doing everything in a single function node…

I would like a JavaScript AddOn similar to the Python Script, PyScript and AppDaemon et al addons.

Given that we already have a Node.js based API maintained by HA GitHub - home-assistant/home-assistant-js-websocket: JavaScript websocket client for Home Assistant is shouldn’t be to wrap in an addon?!

Would need to implement a couple of the features from the REST API too like fetching states and calling services.

Have this been considered/discarded?
Do we have an JS implementation of the REST API features?
