Explore More RobotJS Examples to Supercharge Your Task Automation!

Here are more RobotJS examples to help you explore the different ways you can automate tasks using this powerful library :

---

1. Mouse Movement and Clicks

Example 1: Move Mouse to Specific Coordinates

You can move the mouse to a specific position on the screen using its coordinates.

const robot = require('robotjs');

// Move the mouse to (100, 100) on the screen
robot.moveMouse(100, 100);

Example 2: Smooth Mouse Movement

RobotJS also supports smooth mouse movements, simulating how a human might move the mouse.

robot.moveMouseSmooth(500, 500);

Example 3: Perform a Right-Click

You can simulate a right-click using RobotJS.

// Move to position (300, 300) and perform a right-click
robot.moveMouse(300, 300);
robot.mouseClick('right');

---

2. Keyboard Automation

Example 1: Type a String

RobotJS allows you to simulate typing on the keyboard, making it ideal for automating text input tasks.

// Type out a string like a user would
robot.typeString('Hello, this is RobotJS!');

Example 2: Press a Key Combination (e.g., Ctrl + C)

You can simulate pressing key combinations, such as copying text.

// Simulate pressing Ctrl + C (copy)
robot.keyTap('c', ['control']);

Example 3: Simulate Holding and Releasing Keys

If you want to simulate holding down a key, RobotJS allows you to do that as well.

// Hold down the "control" key, press "a" and then release "control"
robot.keyToggle('control', 'down');
robot.keyTap('a');  // Select all (Ctrl + A)
robot.keyToggle('control', 'up');

3. Pixel Color Detection

Example 1: Get the Color of a Pixel

You can get the color of a specific pixel on the screen, which can be useful for image recognition tasks.

// Get the mouse position and detect the color of the pixel at that location
const mouse = robot.getMousePos();
const color = robot.getPixelColor(mouse.x, mouse.y);
console.log(`The color at (${mouse.x}, ${mouse.y}) is #${color}`);

Example 2: Screenshot a Region and Detect Color

RobotJS can take a screenshot of a portion of the screen and check the pixel colors.

// Take a screenshot of a region (100x100 pixels) starting from (0, 0)
const img = robot.screen.capture(0, 0, 100, 100);

// Get the color of a pixel in the screenshot
const color = img.colorAt(50, 50);  // Get the color at position (50, 50) in the image
console.log(`The color at (50, 50) in the screenshot is #${color}`);

---

4. Screenshots

Example 1: Capture a Screenshot of the Entire Screen

RobotJS can take full-screen or partial screenshots.

const screenSize = robot.getScreenSize();
const screenshot = robot.screen.capture(0, 0, screenSize.width, screenSize.height);

// Save screenshot or process the data
console.log(`Screenshot size: ${screenshot.width}x${screenshot.height}`);

---

5. Delays Between Actions

Example 1: Add Delays Between Actions

You can slow down your automation by adding delays between actions to simulate human-like interaction.

// Move the mouse and add a delay before clicking
robot.moveMouse(400, 400);
robot.setMouseDelay(200);  // Add a delay of 200 milliseconds
robot.mouseClick();

Example 2: Delay Between Typing Characters

To simulate a real typing experience, you can add a delay between each keystroke.

robot.setKeyboardDelay(500);  // Delay of 500 milliseconds between key presses
robot.typeString('Typing with delays...');

---

6. Screen Size and Mouse Position

Example 1: Get Screen Size

If you want your automation to adjust based on the screen size, RobotJS can provide the current screen dimensions.

const screenSize = robot.getScreenSize();
console.log(`Screen size: ${screenSize.width}x${screenSize.height}`);

Example 2: Get Current Mouse Position

You can track the current position of the mouse and use it for further automation.

const mousePos = robot.getMousePos();
console.log(`Mouse is at: (${mousePos.x}, ${mousePos.y})`);

---

7. Scroll Automation

Example 1: Scroll the Mouse Wheel

RobotJS can also scroll the mouse wheel up or down, simulating how users scroll through web pages or applications.

// Scroll down by 10 units
robot.scrollMouse(0, 10);

// Scroll up by 5 units
robot.scrollMouse(0, -5);

---

8. Working with Coordinates

Example 1: Move Mouse Relative to Its Current Position

You can move the mouse relative to its current position rather than absolute screen coordinates.

// Get the current mouse position
const { x, y } = robot.getMousePos();

// Move the mouse 100 pixels right and 50 pixels down from its current position
robot.moveMouse(x + 100, y + 50);
