node-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.
API
=======
````javascript
var headless = require('headless');
headless(function(err, childProcess, servernum) {
// childProcess is a ChildProcess, as returned from child_process.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);
});
````
install
=======
With [npm](http://npmjs.org), 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](https://npmjs.org/package/child-killer) (`npm install child-killer`) and headless will automatically use it.
