Co Etcd

A promise/co wrapper for the node-etcd module. All functions from node-etcd are supported, but are converted to return a promise

'use strict';

let CoEtcd = require('co-etcd');
let co = require('co');

co(function *() {
  let etcd = new CoEtcd('127.0.0.1');
  let result = yield etcd.get('');
  console.log(result);
}).catch((e) => { console.log(e.stack); });

Additions

etcd.nodeToTree()

Arguments

• Javascript object in etcd node format

Returns

• Node format converted into a JSON tree object

Example

let config = yield etcd.get('');
console.log(config);
