Smart.js is based on two projects: - V7: a small portable JS VM (https://github.com/cesanta/v7) - mongoose: a portable async multiprotocol networking library (https://github.com/cesanta/mongoose) Both of those projects are independent and have some traction on their own; but you're right that we should make it more explicit. Mongoose is out there since 2004 and is a quite popular embedded http server. We added many other protocols to it, including also COAP and DNS. Arduino libs are not used because they are not async and not portable. Honestly I don't know about node-red, sounds interesting; however node's V8 VM is too heavyweight for the smallest devices we aim to support. Smart.js does expose a nodejs-compatible core API wherever possible, so it might be possible to port node-red to it.
