Javascript 如何使用persist with node.js？

我正在尝试熟悉这个节点的持久化包。有人能告诉我这里是用persist.connect建立连接还是这些属性

var persist = require("persist");
var type = persist.type;

// define some model objects
Phone = persist.define("Phone", {
  "number": type.STRING
});

Person = persist.define("Person", {
  "name": type.STRING
}).hasMany(this.Phone);

persist.connect({
  driver: 'sqlite3',
  filename: 'test.db',
  trace: true
}, function(err, connection) {
  Person.using(connection).all(function(err, people) {
    // people contains all the people
  });
});

上面的代码在我的系统上运行时不会出错，只要我把它改成。电话对电话

persist.connect连接到包含数据库的test.db文件
