  // ...
});

Retrieve the latest result:

yslow.results.latest(function (err, result) {
  // ...
});

Retrieve the latest result for a URL:

  // ...
});

Remove all results:

yslow.results.removeAll(function (err) {

By default the package is configured to use a MongoDB database at mongodb://127.0.0.1:27017/yslow. To change this, set the environment variable YSLOW_DATA_DB e.g.

EXPORT YSLOW_DATA_DB="mongodb://127.0.0.1:27017/some_db"
