An NPM library used for Node.js/Electron to listen to keyboard and mouse events at the Windows system level.

supported Electron verion:

• "22.3.27", // last LTS Win7 version
• "23.3.13",
• "24.8.3",
• "25.9.0",
• "26.2.0",
• "27.3.0",
• "28.2.0",
• "29.4.0",
• "30.5.1",
• "31.0.0",

Usage

install

npm i @lysyyds/win32-mouse-keyboard-hook

import

// createRequire in Vite-Electron
const require = createRequire(import.meta.url);
// require
const win32KeyboardHook = require("@lysyyds/win32-mouse-keyboard-hook");
// or import
// import win32KeyboardHook from "@lysyyds/win32-mouse-keyboard-hook";

// import types
import type {
  Callback,
  KeyboardEventType,
  MouseEventType,
} from "@lysyyds/win32-mouse-keyboard-hook";

usage

add listener using Nodejs EventEmitter(recommend)

win32KeyboardHook.start();
// keyboard event
hook.on("key", (eventType, x, y) => {
  if (eventType == KeyboardEventType.KeyDown) {
    // keydown
    x; // keycode
  } else if (eventType == KeyboardEventType.KeyUp) {
    // keyup
    x; // keycode
  }
});

// mouse event
hook.on("mouse", (eventType, x, y) => {
  x; // mouse position x
  y; // mouse position y

  if (eventType == MouseEventType.LeftDown) {
    // mouse left button down
  } else if (eventType == MouseEventType.LeftUp) {
    // mouse left button up
  } else if (eventType == MouseEventType.RightDown) {
    // mouse right button down
  } else if (eventType == MouseEventType.RightUp) {
    // mouse right button up
  } else if (eventType == MouseEventType.Wheel) {
    // wheel active
  }
});

// when you need to stop
win32KeyboardHook.stop();

add listener at initial

const callback: Callback = (type, eventType, x, y) => {
  const [type, eventType, x, y] = args;
  if (type === "key") {
    // keyboard event
    if (eventType == 1) {
      // keydown
      x; // keycode
    } else if (eventType == 2) {
      // keyup
      x; // keycode
    }
  } else if (type === "mouse") {
    x; // mouse position x
    y; // mouse position y

    if (eventType == 2) {
      // mouse left button down
    } else if (eventType == 3) {
      // mouse left button up
    } else if (eventType == 4) {
      // mouse right button down
    } else if (eventType == 5) {
      // mouse right button up
    } else if (eventType == 6) {
      // wheel active
    }
  }
};

win32KeyboardHook.start(callback);
