GKM

An event based, Global Keyboard and Mouse listener.

Tested on Windows 7 (and Linux), but should work on Mac OS X as well (untested).

Why?

Node didn't have any global keyboard and mouse listener available at the time.

Requirements

GKM depends on JNativeHook, which runs on Java. Thus you will need to have a JVM available and more importantly, java availble on your PATH.

In the lib folder, you will find gkm.jar, which source you can find at https://github.com/tomzx/gkm-java. You will also find JNativeHook.jar, which source you can find at https://github.com/kwhat/jnativehook.

Getting started

Install gkm via node.js package manager:

npm i gkm-class

Then require the package in your code.

ALWAYS remember to run gkm.quit() when you are done with GKM, otherwise java will continue running.

import GKM from 'gkm-class';

const gkm = new GKM();

// Listen to all key events (pressed, released, typed)
gkm.on('key.*', function(data) {
    console.log(this.event + ' ' + data);
});

// Listen to all mouse events (click, pressed, released, moved, dragged)
gkm.on('mouse.*', function(data) {
	console.log(this.event + ' ' + data);
});

// Close gkm in 10 seconds
setTimeout(() => {
    gkm.quit(); // Close java and remove listeners
}, 10000);
