Copy to clipboard in NodeJS?

Is there a way you can copy to clipboard in NodeJS? Any modules or ideas what so ever? I'm using Node on a desktop application, hopefully that clears up why I want it to be able to achieve this.


A clipboard is not inherent to an operating system. It's a construct of whatever window system the operating system happens to be running. So if you wanted this to work on X for example, you would need bindings to Xlib and/or XCB. Xlib bindings for node actually exist: Although I'm not sure whether it gives you access to the X clipboard, you might end up writing your own. You'll need separate bindings for windows.

edit: If you want to do something hacky, you could also use xclip:

var exec = require('child_process').exec;

var getClipboard = function(func) {
  exec('/usr/bin/xclip -o -selection clipboard', function(err, stdout, stderr) {
    if (err || stderr) return func(err || new Error(stderr));
    func(null, stdout);

getClipboard(function(err, text) {
  if (err) throw err;
