node-xvfb: easily start and stop an X Virtual Frame Buffer from your node apps.

Usage

var Xvfb = require('xvfb');
var xvfb = new Xvfb();
xvfb.start(function(err, xvfbProcess) {
  // code that uses the virtual frame buffer here
  xvfb.stop(function(err) {
    // the Xvfb is stopped
  });
});

The Xvfb constructor takes four options:

• displayNum - the X display to use, defaults to the lowest unused display number >= 99 if reuse is false or 99 if reuse is true.
• reuse - whether to reuse an existing Xvfb instance if it already exists on the X display referenced by displayNum.
• timeout - number of milliseconds to wait when starting Xvfb before assuming it failed to start, defaults to 500.
• silent - don't pipe Xvfb stderr to the process's stderr.
• xvfb_args - Extra arguments to pass to Xvfb.
