I’m a mobile enterprise/game developer with lots of years of experience - but i’m pretty new to JS and nodejs. So this project works both as my practice of working with JS project, and it already helps me to deal with JS syntax and business logic via the debug.
In short: it can run n8n Code node code 
locally via nodejs, including debug feature. Project includes the same libs as n8n.
It works fine for coding some small logic blocks.
