A nodejs library for etcd, written in coffee-script.
Travis-CI:
$ npm install node-etcd
# Coffee-script examples:
Etcd = require 'node-etcd'
c = new Etcd
# Set a value
c.set "/key", "value", (err, val) ->
console.log err, val
# Get a value
c.get "/key", (err, val) ->
console.log err, val
# Delete a value
c.del "/key", (err, val) ->
console.log err, val
# Watch a value (wait for a single value change)
c.watch "/key", (err, val) ->
console.log err, val
# Watcher retuns an eventemitter for continuously watching changes,
# it also handles reconnect on error, etc..
w = c.watcher '/key'
w.on 'change', console.log
w.on 'reconnect', console.log
# Set with expiry (time to live)
c.setTTL "/key", "value", 5, (err, val) ->
console.log err, val
# Atomic setting (test and set)
c.setTest "/key", "new value", "old value", (err, val) ->
console.log err, val
# List machines in the etcd cluster
c.machines (err, val) ->
console.log err, val
# Get the leader of the cluster
c.leader (err, val) ->
console.log err, val
# Statistics (leader and self)
c.leaderStats (err, val) -> console.log err, val
c.selfStats (err, val) -> console.log err, val
# SSL Support
# Pass etcd a dictionary containing ssl options
# Check out http://nodejs.org/api/https.html#https_https_request_options_callback
