后来，我找到了一个很好的用于管理配置的Node.js模块：nconf。

一个简单的例子：

var nconf = require('nconf');

// First consider commandline arguments and environment variables, respectively.
nconf.argv().env();

// Then load configuration from a designated file.
nconf.file({ file: 'config.json' });

// Provide default values for settings not provided above.
nconf.defaults({
    'http': {
        'port': 1337
    }
});

// Once this is in place, you can just use nconf.get to get your settings.
// So this would configure `myApp` to listen on port 1337 if the port
// has not been overridden by any of the three configuration inputs
// mentioned above.
myApp.listen(nconf.get('http:port'));

它还支持在Redis中存储设置，编写配置文件，并具有相当可靠的API，并且作为Flatiron框架计划的一部分，还得到了备受推崇的Node.js商店之一Nodejitsu的支持。相当适合未来。
