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

Usage

varXvfb=require('xvfb');varxvfb=newXvfb();xvfb.startSync();// code that uses the virtual frame buffer herexvfb.stopSync();// the Xvfb is stopped

or:

varXvfb=require('xvfb');varxvfb=newXvfb();xvfb.start(function(err,xvfbProcess){// code that uses the virtual frame buffer herexvfb.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.
