Connect to spawned server

[phoboslab]

Pardon my ignorance. I can't figure out how to actually connect to the spawned server. I've been previously using (without nodejs) xvfb-run -a some-binary – how would I translate that to this library?

I've tried the following

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

headless(function(err, childProcess, servernum) {
    exec('xvfb-run -n '+ servernum + ' some-binary', error, stdout, stderr) {
        console.log('stdout:', stdout);
        console.log('stderr:', stderr);

        // kill the xvfb server - is this the correct place to do this?
        childProcess.kill();
    });
});

But this only emits "error: Xvfb failed to start", as if servernum were invalid.

headless will start the xvfb instance so no need to do the exec('xvfb-run... stuff.

The servernum is invalid since there's been a server opened w that servernum already from the headless library.

So I just do exec('some-binary) inside the headless() callback? Wow, sorry, that didn't cross my mind.

Thank you!
