The unofficial Couchbase Node.js Client Library.

Usage no npm install needed!

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.

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://');
// 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;

    // {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;

    // {name: Frank}
