Quick start

const Cz = require('cz');
const config = new Cz();
 
// Loads the config file into Cz
config.load('./config.json');
 
// Sets Cz's default value for "port" to 4000
// If the value is unset using config.set('port', null) then Cz will fall back to 4000
config.defaults({
    port: 4000
});
 
// Sets Cz to { random: 'random value' }
config.set('random', 'random value');
 
// This will return the whole config object currently loaded
console.log('config', config.get());
 
// This will get { db:{ host:{} } } from the config object
console.log('db:host', config.get('db:host'));
 
// Here's a typical example of how this is used
console.log('mongodb://' + config.get('db:username') + ':' + config.get('db:password') + '@' + config.get('db:host') + ':' + config.get('db:port') + '/' + config.get('db:collection'));
 
// Cz provides a little helper to join gets for you
console.log('mongodb://' + config.joinGets(['db:username', 'db:password', 'db:host', 'db:port', 'db:collection'], [':', '@', ':', '/']));

Cz sets defaults() as the most bottom object and applies all changes to the config object on top of that meaning anywhere in your app you can use config.defaults({}) to override the default values.

const config = require('cz');
 
config.defaults({
    port: 4000,
    logging: false
});
 
config.set('port', 5000);
config.get('port'); // 5000
 
config.reset();
config.get('port'); // 4000

To reset defaults just use config.defaults({}); To reset the config itself we provide config.reset();
