I'm trying to integrate Node-Red into some of my ARM-based devices (and x86 as a variant for a dedicated server). I use last stable Buildroot release as core cross-compiler system but has some problems with its node.js -- compiled binaries does not try to execute any simple HelloWorld.js (including npm).
This problem is not tightened with the node-red project, but maybe somebody does the same thing with some problems and can help to create reference project integrates node-red into IoT edge level devices.
