A Javascript library for Riak

Features so far

  • Sensible yet overridable defaults (init, per-request)
  • Operations: get bucket, get doc, save, remove, walk, map/reduce
  • Available for node.js (v0.1.90+) and browser/jQuery platforms and Riak 0.8+


All operations take an options object as the last argument. These specified options will override the defaults, which are defined as:

  method: 'GET',
  interface: 'riak',
  headers: {},
  returnbody: false,
  debug: true,
  callback: function(response, meta) {
    if (response)
      Riak.prototype.log(meta.headers['content-type'] === 'application/json' ? JSON.stringify(response) : response)
  errback: function(response, meta) {
    if (response)
      Riak.prototype.log((meta ? meta.statusCode + ": " : "") + response, 'error')

During client instantiation, defaults are localhost for the host and 8098 for the port. If you pass-in the defaults as the last argument, they will apply to the whole session instead of per-request:

var db = new Riak.Client(8098, 'localhost', { interface: 'bananas', debug: false });

Set up


var Riak = require('riak-node'), db = new Riak.Client();

Also available through kiwi: kiwi install riak-js

In the browser with jQuery

var db = new Riak();

An example session

Get and save a document

 db.get('albums', 4)(function(album, meta) {
     album.tracks = 12;; // here we use the provided default callbacks that log the result

Check out the airport-test.js file for more.

Save an image

fs.readFile("/path/to/your/image.jpg", 'binary', function (err, data) {
  if (err) throw err;'images', 'test', data, { requestEncoding: 'binary', headers: { "content-type": "image/jpeg"} })();

Noteworthy points

  • All operations return a function that takes two arguments (two functions: callback and errback). Therefore you must call it for something to happen: db.get('bucket')() (default callbacks), or db.get('bucket', 'key')(mycallback, myerrback)
  • These functions are passed in two arguments, the response object and a meta object: var mycallback = function(response, meta) {}
  • Headers are exposed through meta.headers and the status code through meta.statusCode
  • All operations accept an options object as the last argument, which will be mixed-in as to override certain defaults
  • If no Content-Type header is provided, application/json will be assumed - which in turn will be serialized into JSON
  • Link-walking is done through the map/reduce interface
  • If no language is provided in any map/reduce phase, language: javascript is assumed
  • http.Client queues all requests, so if you want to run requests in parallel you need to create one client instance for each request
