headless

node-headless makes it easy to start and use Xvfb in node. headless is inspired by xvfb-run - it searches for a free X display number and starts Xvfb on that.

````javascript var headless = require('headless');
headless(function(err, childProcess, servernum) { // childProcess is a ChildProcess, as returned from childprocess.spawn() console.log('Xvfb running on server number', servernum); console.log('Xvfb pid', childProcess.pid); console.log('err should be null', err); }); ````
headless also support an optional number to start searching from.
````javascript var headless = require('headless');
headless(200, function(err, childProcess, servernum) { // servernum will be at least 200 console.log('Xvfb running on server number', servernum); console.log('Xvfb pid', childProcess.pid); }); ````
Options:

• display: optional display parameters (width, height & depth). If you want to specify display, width and height are required, but depth is optional and defaults to 16.
• args: an array of arbitrary additional Xvfb arguments
• stdio: set the stdio of the spawned Xvfb process(es). Set this to 'inherit' to see Xvfb's stdout and stderr for debugging purposes.

````javascript var headless = require('headless');
var options = { display: {width: 1024, height: 980, depth: 32}, args: '-extension', 'RANDR', stdio: 'inherit' };
headless(options, function(err, childProcess, servernum) { // childProcess is a ChildProcess, as returned from childprocess.spawn() console.log('Xvfb running on server number', servernum); console.log('Xvfb pid', childProcess.pid); console.log('err should be null', err); }); ````

install

With npm, do:

npm install headless

If you're having problems with Xvfb-instances not getting killed correctly, and is running on a platform that the posix-module supports, install child-killer (npm install child-killer) and headless will automatically use it.Copyright (c) 2014 David Björklund
