Examples

Mouse

// Move the mouse across the screen as a sine wave.
var robot = require("robotjs");

// Speed up the mouse.
robot.setMouseDelay(2);

var twoPI = Math.PI * 2.0;
var screenSize = robot.getScreenSize();
var height = (screenSize.height / 2) - 10;
var width = screenSize.width;

for (var x = 0; x < width; x++)
{
	y = height * Math.sin((twoPI * x) / width) + height;
	robot.moveMouse(x, y);
}

Keyboard

// Type "Hello World" then press enter.
var robot = require("robotjs");

// Type "Hello World".
robot.typeString("Hello World");

// Press enter.
robot.keyTap("enter");

Screen

// Get pixel color under the mouse.
var robot = require("robotjs");

// Get mouse position.
var mouse = robot.getMousePos();

// Get pixel color in hex format.
var hex = robot.getPixelColor(mouse.x, mouse.y);
console.log("#" + hex + " at x:" + mouse.x + " y:" + mouse.y);
