Couchbase Node.js Client

The Node.js SDK library allows you to connect to a Couchbase cluster from Node.js. It is a native Node.js module and uses the very fast libcouchbase library to handle communicating to the cluster over the Couchbase binary protocol.

Installing

To install the lastest release using npm, run:

npm install couchbase

To install the development version directly from github, run:

npm install "git+https://github.com/couchbase/couchnode.git#master"

Introduction

Connecting to a Couchbase bucket is as simple as creating a new Cluster instance to represent the Cluster you are using, and then executing openBucket against this to open a connection to you specific bucket. You are able to execute most operations immediately, and they will be queued until the connection is successfully established.

Here is a simple example of instantiating a connection, adding a new document into the bucket and then retrieving its contents:

var couchbase = require('couchbase');
var cluster = new couchbase.Cluster('couchbase://127.0.0.1');
// For Couchbase > 4.5 with RBAC Auth
cluster.authenticate('username', 'password')
var bucket = cluster.openBucket('default');

bucket.upsert('testdoc', {name:'Frank'}, function(err, result) {
  if (err) throw err;

  bucket.get('testdoc', function(err, result) {
    if (err) throw err;

    console.log(result.value);
    // {name: Frank}
  });
});

Mock Testing

As part of the core library, we additionally include a powerful Mock version of the library which supports a significant set of the features that are available when connected to a real Couchbase Server.

As part of this library, we include a mock version of the client that supports nearly the exact same feature set as the library itself, but which does not require that a server be configured. Note that these Mock connections currently are per-instance, if another connection is instantiated, none of the data will be shared.

Using the Mock is as simple as this:

var couchbase = require('couchbase').Mock;
var db = new couchbase.Cluster();
var bucket = cluster.openBucket();

bucket.upsert('testdoc', {name:'Frank'}, function(err, result) {
  if (err) throw err;

  bucket.get('testdoc', function(err, result) {
    if (err) throw err;

    console.log(result.value);
    // {name: Frank}
  });

Documentation

An extensive documentation is available on the Couchbase website. Visit our Node.js Community on the Couchbase website for the documentation as well as numerous examples and samples.

Source Control

The source code is available at https://github.com/couchbase/couchnode. Once you have cloned the repository, you may contribute changes through our gerrit server. For more details see CONTRIBUTING.md.

To execute our test suite, run make test from the root directory.

To execute our code coverage, run make cover from the root directory.

In addition to the full test suite and full code coverage, you may additionally execute a subset of the tests which excludes slow-running tests for quick verifications. These can be run through make fasttest and make fastcover respectively.
