Kue: best practice for continuously processing/polling the queue

What is the best way to continuously process items added to the queue? I see the following method

queue.process

https://github.com/Automattic/kue#processing-jobs

but this will process and return. Items added after this call are obviously not processed.

I thought to do:

queue.on('job enqueue', function(id, type){
            queue.process('email', function (job, done) {
                console.log('processing one: ' + job.id);
                done(null);
            });
        });

But not sure if this fires multiple process methods ignoring the current queue status?
