In the area of micro:bit and https://pxt.microbit.org/ an electron app was under way, but was taking too much time, so a while, I maintained a way of running pxt as ... an electron app which can still work but MS is almost finished and it's usage was nearly finished in relation to my use. https://github.com/microbit-drill/epxt
