The clickMouse function uses the node-screenshots and mouse-controller modules to simulate a left mouse click at a specified position (x, y) on the primary monitor. This function is exported as a module, making it available for use in other scripts.

Run example

npm run import -- "mouse click"

mouse click

const { Monitor } = require("node-screenshots")
const MouseController = require('mouse-controller')
const mc = new MouseController();

function clickMouse(x, y) {
  let monitors = Monitor.all()
  monitors.sort((a, b) => (a.x + a.y) - (b.x + b.y))
  /*console.log({
    x: monitors[0].x,
    y: monitors[0].y,
    width: monitors[0].width,
    height: monitors[0].height,
  })*/
  mc.click(mc.BUTTON.LEFT, {x: x * monitors[0].width * 3 + monitors[0].x, y: y * monitors[0].height})
}

module.exports = clickMouse

const { Monitor } = require('node-screenshots');
const MouseController = require('mouse-controller');

/**

  }

Code Breakdown

Dependencies

• node-screenshots: A Node.js module for capturing screenshots.
• mouse-controller: A Node.js module for controlling the mouse.

Functions

clickMouse(x, y)

• Requires the MouseController module and creates a new instance.
• Uses the Monitor.all() method from node-screenshots to get an array of available monitors.
• Sorts the monitors by their combined x and y coordinates.
• Calculates the mouse click position by scaling the input coordinates (x and y) by the monitor's width and height, then adds the monitor's offset.
• Simulates a left mouse click at the calculated position using mouse-controller.

Export

• Exports the clickMouse function as a module, making it available for use in other scripts.
