input-event

nodejs module for reading keyboard & mouse events from /dev/input/eventX (the linux event interface)

based on github.com/Bornholm/node-keyboard, which in turn was based on http://nodebits.org/linux-joystick. This was tested on a Raspberry Pi with a 32-bit kernel. There is code to detect 64-bit kernel but it is untested.

Usage

See demo.js

var input-event = require('input-event');

var k = new input-event('event0'); // 'event0' is the file corresponding to my keyboard in /dev/input/
k.on('keyup', console.log);
k.on('keydown', console.log);
k.on('keypress', console.log);
k.on('rel', console.log);
k.on('abs', console.log);
k.on('syn', console.log);
