I created a micro-library for controlling your SparkCore from Node.js: https://github.com/KevinGrandon/sparky
It’s basically just syntactic sugar at this point, but I hope to keep hacking on it and building it out further. Let me know if you have any suggestions/needs. I will likely need to make a lot of updates as I play with and integrate sensors.
Also if there are any existing node.js libraries, please link them - I was having a hard time finding existing stuff. Thanks!
