Jane,
I gave you references to information on how to build libraries and your application for mLinux. I pointed out how you could build the libmosquitto package to install on your mLinux as an example and also so that you can build your application against it. I do not know what every package you need is. I mentioned nothing about node.js, though you can build the package for node and install that for use on an mLinux Conduit also if need be.
