etcd2json

turn etcd configs to json

Rules

• A Dictionary is an Object or Array.
• A Property is a key-value pair, or Array Element.
• If the name of Dictionary or Property is a number, then the parent node will be casted into an Array
• String true and false will be turned into Boolean
• If number and letter key name exists in the same level, the final result will be decided by the last element.
• Empty Property and Dictionary will be turned into '' and {}

Usage

var etcd2json = require('etcd2json');
var etcdHosts = process.env.ETCD_HOST.split(',') || ['127.0.0.1:2379'];
var etcdClient = new Etcd(etcdHosts);
var defaultResult = etcd2json.retrieve(etcdClient, '/v1/production/default');
var appResult = etcd2json.retrieveMultiPath(etcdClient, ['/v1/production/default', '/v1/production/app1']);

There are two functions, retrieve and retrieveMultiPath. You can pass an array to retrieveMultiPath function. The latter value will overwrite the previous value, if they have the same key.
