So, a pretty exciting thing happened recently!
It is all available here: https://github.com/microsoft/node
You can read some more info about it here: http://blogs.windows.com/buildingapps/2015/05/12/bringing-node-js-to-windows-10-iot-core
This work brings node.js to 2 new places:
- ARM devices running Windows
- Modern Windows store apps.
And if you're curious to see what it takes to replace v8 with Chakra, the shim layer for the v8 API that uses Chakra is available here: https://github.com/Microsoft/node/tree/ch0.12.2/deps/chakrashim
