node-udev - list devices in system and detect changes on them

This library attempts to follow the libudev where it makes sense. I only needed some usb input device detection so I was happy with quite few features.

Requires node-v10.0.0, nan and libudev.

Installation

npm install udev

Installation on debian/ubuntu

sudo apt-get install libudev-dev
npm install udev

How to Use

The example below lists devices and monitors udev events on the ipnut subsystem until receiving an add event. The code is separately listed in samples/howto.js.

var udev = require("udev");

console.log(udev.list()); // this is a long list :)

var monitor = udev.monitor("input");
monitor.on('add', function (device) {
    console.log('added ' + device);
    monitor.close() // this closes the monitor.
});
monitor.on('remove', function (device) {
    console.log('removed ' + device);
});
monitor.on('change', function (device) {
    console.log('changed ' + device);
});

The example below lists devices belonging to subsystem "tty" i.e. various serial ports.

var udev = require('udev');
console.log(udev.list('tty'));
