    Couchbase Node.js Client

    This 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 Connection instance. Once you are connect, you may execute any of Couchbases' numerous operations against this connection.

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

        var couchbase = require('couchbase');
        var db = new couchbase.Connection({bucket: "default"}, function(err) {
          if (err) throw err;
          db.set('testdoc', {name:'Frank'}, function(err, result) {
            if (err) throw err;
            db.get('testdoc', function(err, result) {
              if (err) throw err;
              // {name: Frank}

    Mock Testing

    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.Connection();
