Node.js Desktop Automation. Control the mouse, keyboard, and read the screen.
RobotJS supports Mac, Windows, and Linux.
This is a work in progress so the exported functions could change at any time before the first stable release (1.0.0). Ideas?
Check out some of the cool things people are making with RobotJS! Have your own rad RobotJS project? Feel free to add it!
Install RobotJS using npm:
npm install robotjs
It's that easy! npm will download one of the prebuilt binaries for your OS.
You can get npm here if you don't have it installed.
If you need to build RobotJS, see the building section. Instructions for Electron.
// 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);
}
// Type "Hello World" then press enter.
var robot = require("robotjs");
// Type "Hello World".
robot.typeString("Hello World");
// Press enter.
robot.keyTap("enter");
// 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);

Module | Status | Notes |
---|---|---|
Mouse | 100% | All planned features implemented. |
Keyboard | 100% | All planned features implemented. |
Screen | 85% | Image search, pixel search. |
Bitmap | 0% | Saving/opening, png support. |
Not currently, and I don't know if it ever will. I personally use Electron/NW.js for global hotkeys, and this works well. Later on I might add hotkey support or create a separate module. See #55 for details.
Soon! This is a bit more complicated than the rest of the features, so I saved it for last. Luckily the code is already there, I just need to write the bindings, and I've already started. Subscribe to #13 for updates.
We've been implementing keys as we need them. Feel free to create an issue or submit a pull request!
The library doesn't have explicit multi-monitor support, so anything that works is kind of on accident. Subscribe to #88 for updates.
For any other questions please submit an issue.
I'm a huge fan of AutoHotkey, and I've used it for a very long time. AutoHotkey is great for automation and it can do a bunch of things that are very difficult in other languages. For example, it's imagesearch and pixel related functions are hard to reproduce on Mac, especially in scripting languages. These functions are great for automating apps that can't be automated like Netflix. This has never been a big deal since I've always used Windows at work, but for the past few years I've been using Mac exclusively.
I like AutoHotkey, but I like Node.js more. By developing RobotJS I get an AutoHotkey replacement on Mac (finally!), and I get to use my favorite language.
TLDR: There's nothing like AutoHotkey on Mac, so I'm making it.
