Hazelcast Node.js Client

NOTE: This project is currently in active development.

This document explains Node.js client for Hazelcast which uses Hazelcast's Open Client Protocol 1.0. This client works with Hazelcast 3.6 and higher.

Hazelcast is a clustering and highly scalable data distribution platform. With its various distributed data structures, distributed caching capabilities, elastic nature and more importantly with so many happy users, Hazelcast is a feature-rich, enterprise-ready and developer-friendly in-memory data grid solution.

Features

Hazelcast Node.js client supports the following data structures and features:

Map (including entry processors and PartitionAware keys) and MultiMap
Queue, Set, and List
Lock
Smart Client
Hazelcast Native Serialization
Distributed Object Listener
Lifecycle Service

Installing the Client

Following command installs Hazelcast Node.js client:

npm install hazelcast-client --save

Using the Client

Following script illustrates a basic example in which a map is created in Hazelcast Node.js client and an entry is added to that map:

var HazelcastClient = require('hazelcast-client').Client;
var person = {
    firstName: "Joe",
    lastName: "Doe",
    age: 42
};
var map;
HazelcastClient.newHazelcastClient().then(function (hazelcastClient) {
    map = hazelcastClient.getMap("personMap");
    map.put(1, person).then(function (val) {
        // prints previous value for key `1`
        console.log(val);
    });
    map.get(1).then(function (value) {
        console.log(value);
    })
});

Please see Hazelcast Node.js code samples for more examples.
