I need get screen resolution with node.js, but the following code don't work.

var w = screen.width;
var h = screen.height;

This also don't work.

var w = window.screen.width;
var h = window.screen.height;

Someone know how to get screen resolution with node.js ? Thank you.

Solution 1

I solved the problem with phantomJS.

Install phantomJS:

sudo apt-get install phantomjs

Create app.js file:

var w = screen.width;
var h = screen.height;
console.log(w+"x"+h);
phantom.exit();

Execute:

phantomjs app.js

Return:

1366x768

Solution 2

There is now a screenres module via npm:

https://www.npmjs.com/package/screenres

Thanks Eugene, but i want get screen resolution of the server same.

If you run a browser on the server you can run the client-side script in that browser and send the data to the server-side application in same way.

In the common case of Linux servers running multiple displays, X11 defaults internally to a single huge aggregate window. Phantomjs will return that resolution. Eugene's answer will return the resolution of whatever display the browser is running on, regardless of OS, or how its window manager is configured.

This entire module is just ``` const robot = require("robotjs") module.exports = robot.getScreenSize() ``` And robotjs does not support multi-monitor btw.

@Arbiter How would you like it to handle multi-monitor support?

I would like it to tell me the number of monitors and the widths and heights of each monitor?
