An etcd store for nconf

nconf-etcd

An etcd store for nconf

Installation

npm install nconf-etcd

Usage

var nconf = require('nconf');
// requiring nconf will register it to nconf
require('nconf-etcd');

// tell nconf to use etcd and specify hostname and port etc
// below are the default values..
nconf.use('etcd', {host: 'localhost', port: '4001', namespace:'nconf'});

Cache

When using nconf, beware that the built-in api enforces a usage of cache to enable the syncronous nconf.get('key') behaviour. If you want to turn off cache to be sure to always get the actual etcd value - set options.cache = false and always use the asynchronous nconf.get('key', function(err, value){..}) instead.

nconf.use('etcd', {host: 'localhost', port: '4001', cache: false});

Limitations

In the current alpha version, only async get operations are supported. Meaning this is NOT supported yet:

var host = nconf.get('host');

currently you have to write like this:

nconf.get('host', function(err, host){
    ...
})
