Libmraa is a C/C++ library with bindings to javascript & python to interface with the IO on Galileo, Edison & other platforms, with a structured and sane API where port names/numbering matches the board that you are on. Use of libmraa does not tie you to specific hardware with board detection done at runtime you can create portable code that will work across the supported platforms.
The intent is to make it easier for developers and sensor manufacturers to map their sensors & actuators on top of supported hardware and to allow control of low level communication protocol by high level languages & constructs.
See the section below on compiling or use our repository to install on an eglibc based yocto poky image that supports opkg. Adding this repository is as simple as:
echo "src mraa-upm http://iotdk.intel.com/repos/1.1/intelgalactic" > /etc/opkg/mraa-upm.conf
opkg update
opkg install libmraa0

The C/C++ documentation is available here
The Python documentation is available here
There is no explicit nodejs API documentation, see the examples. The API itself is very similar to the python one but with a js syntax. If you know of an autodoc tool for generating nodejs APIs from a native C++ nodejs extension please get in touch!
