Installation

This module use native library libuiohook and require some installed packages.
I really hope find way for use build systems for online build or download prebuild packages.

npm i git+https://github.com:renjfk/iohook.git

Electron users [optional]

Before install this module, you need specify build runtime. Just add following to your package.json file (if you use two-package-json structure, add to app's package.json, not to build).
Checkout your ABI for node.js or electron

"iohook": {
  "targets": [
    "node-51",
    "electron-53"
  ],
  "platforms": [
    "win32",
    "darwin",
    "linux"
  ],
  "arches": [
    "x64",
    "ia32"
  ]
}

NOTE: Please remember, when you install iohook, it try to use current node environment NOT ELECTRON OR NW.js

Manual compilation for your version of environment

iohook have prebuild binaries, it downloads when you try to install it.
But if you use specified version of node.js/nw.js/io.js/electron/etc. you can try compile it.
All what you need install os dependencies and start compilation:

Ubuntu 16

  • sudo apt install libx11-dev libxtst-dev libxt-dev libx11-xcb-dev
  • sudo apt install libxkbcommon-dev libxkbcommon-x11-dev
  • cd node_modules/iohook
  • npm run build

macOS

  • brew install cmake automake libtool pkg-config
  • cd node_modules/iohook
  • npm run build

Windows

  • for Node.js usage just make sure that you have installed following components and it will be built by install script
  • for Electron go to installation dir (node_modules/iohook) and recompile it according to your Electron version. e.g. cmake-js rebuild -r electron -v 1.7.1

Usage

Module is pretty simple for use. There is example:

'use strict';
const ioHook = require('iohook');

ioHook.on("mousemove", event => {
  console.log(event);
  /* You get object like this
    {
      type: 'mousemove',
      x: 700,
      y: 400
    }
   */
});

//Register and start hook
ioHook.start();

If type ioHook.start(true); you can enable debug logger in native lib. Use it if you have troubles with this module

Calls when user press a key. Event contain next object:
{ keychar: 'd', keycode: 46, rawcode: 8, type: 'keydown' }

keyup

Calls when user release a key. Event contain next object:
{keychar: 'f', keycode: 19, rawcode: 15, type: 'keup'}

Known issues

In some cases, most often when you make mouse moves or keyboard events very fast, module crash with "Segmentation fault: 11". Looks like it is problem in my native implementation, but I still can't find a problem. Will be happy if somebody helps with it.
