Aerospike Node.js Client

The Aerospike Node.js client is a Node.js add-on module, written using V8.

Usage

The following is very simple example how to create, update, read and remove a record using the Aerospike database.

const Aerospike = require('aerospike')

// INSERT HOSTNAME AND PORT NUMBER OF AEROPSIKE SERVER NODE HERE!
const config = {
  hosts: '192.168.33.10:3000',
  // Timeouts disabled, latency varies with hardware selection. Configure as needed.
  policies: {
    read : new Aerospike.WritePolicy({socketTimeout : 0, totalTimeout: 0}),
    write : new Aerospike.ReadPolicy({socketTimeout : 0, totalTimeout: 0})
  }
}

const key = new Aerospike.Key('test', 'demo', 'demo')

Aerospike.connect(config)
  .then(client => {
    const bins = {
      i: 123,
      s: 'hello',
      b: Buffer.from('world'),
      d: new Aerospike.Double(3.1415),
      g: Aerospike.GeoJSON.Point(103.913, 1.308),
      l: [1, 'a', {x: 'y'}],
      m: {foo: 4, bar: 7}
    }
    const meta = { ttl: 10000 }
    const policy = new Aerospike.WritePolicy({
      exists: Aerospike.policy.exists.CREATE_OR_REPLACE,
      // Timeouts disabled, latency varies with hardware selection. Configure as needed.
      socketTimeout : 0, 
      totalTimeout: 0
    })

    return client.put(key, bins, meta, policy)
      .then(() => {
        const ops = [
          Aerospike.operations.incr('i', 1),
          Aerospike.operations.read('i'),
          Aerospike.lists.append('l', 'z'),
          Aerospike.maps.removeByKey('m', 'bar')
        ]

        return client.operate(key, ops)
      })
      .then(result => {
        console.log(result.bins) // => { i: 124, l: 4, m: null }

        return client.get(key)
      })
      .then(record => {
        console.log(record.bins) // => { i: 124,
                                 //      s: 'hello',
                                 //      b: <Buffer 77 6f 72 6c 64>,
                                 //      d: 3.1415,
                                 //      g: '{"type":"Point","coordinates":[103.913,1.308]}',
                                 //      l: [ 1, 'a', { x: 'y' }, 'z' ],
                                 //      m: { foo: 4 } }
      })
      .then(() => client.close())
  })
  .catch(error => {
    console.error('Error: %s [%i]', error.message, error.code)
    if (error.client) {
      error.client.close()
    }
  })

Prerequisites

The client is compatible with Node.js 10, 12 (LTS), 14 (LTS), 16 (LTS) and 18 (LTS). It supports the following operating systems: CentOS/RHEL 7/8, Debian 8/9/10/11, Ubuntu 18.04/20.04, as well as many Linux distributions compatible with one of these OS releases. macOS is also supported. The client port to Windows is a community supported project and suitable for application prototyping and development.

The Aerospike Node.js client supports all Node.js LTS releases. To download and install the latest stable version of Node.js, visit nodejs.org or use the version that comes bundled with your operating system.

Install the necessary "development tools" and other libraries to build the client software.

Reference various docker files in the repository under the docker / directory for more information.

CentOS/RHEL

To install library prerequisites using yum:

sudo yum group install "Development Tools" 
sudo yum install openssl openssl-devel
sudo yum install python3 python3-devel

Alpine Linux

apk add build-base \
    linux-headers \
    bash \
    libuv-dev \
    openssl-dev \
    lua5.1-dev \
    zlib-dev \
    git \
    python3

Amazon Linux

yum groupinstall "Development Tools"
yum install openssl openssl-devel
yum install python3 python3-devel

Debian

To install library prerequisites using apt-get:

sudo apt -y install software-properties-common
sudo apt -y install build-essential
sudo apt -y install libssl-dev
sudo apt -y install libarchive-dev cmake rsync curl libcurl4-openssl-dev zip
sudo apt -y install python3 python3-dev python3-pip
sudo apt install zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev \
    libsqlite3-dev libreadline-dev libffi-dev libbz2-dev -y
sudo apt -y install wget libtool m4 automake

Ubuntu

To install library prerequisites using apt:

sudo apt install g++ libssl libssl-dev zlib1g-dev

macOS (Intel)

Before starting with the Aerospike Nodejs Client, verify that you have the following prerequisites:

• macOS 10.8 or greater.
• Xcode 5 or greater.

macOS (M1 Chip)

Currently the C library does not support M1, so you cannot install Aerospike Nodejs Client directly on your mac, see Issue. As a workaround, you can build your app inside of Docker before using --platform option. Example of a working docker-compose.yaml file looks similar to this:

version: '2.4'
services:
  my-node-js-app:
    build: .
    platform: linux/amd64

Openssl Library

The below example shows how to install the Openssl library.

$ brew install openssl
$ brew link openssl --force
$ unlink /usr/local/opt/openssl
$ # Change the below linking based on openssl version and installation path
$ ln -s /usr/local/Cellar/openssl@x/y.z/ /usr/local/opt/openssl

For 4x client support, install openssl@1.1 version.

LIBUV Library

The example below shows how to install the LIBUV library.

$ brew install libuv
$ brew link libuv --force
$ unlink /usr/local/opt/libuv
$ # Change the below linking based on libuv version and installation path
$ ln -s /usr/local/Cellar/libuv/1.44.1_1/ /usr/local/opt/libuv

Installation

The Aerospike Node.js client is an add-on module that uses the Aerospike C client. The installation will attempt to install the pre-built binaries including dependent C client.

You can install the Aerospike Node.js client like any other Node.js module.

Primer on Node.js Modules

Node.js modules are containers of JavaScript code and a package.json, which defines the module, its dependencies and requirements. Modules are usually installed as dependencies of other Node.js applications or modules. The modules are installed in the application's node_modules directory, and can be utilized within the program by requiring the module by name.

npm Registry Installations

To install aerospike as a dependency of your project, in your project directory run:

$ npm install aerospike

To add aerospike as a dependency in package.json, run:

$ npm install aerospike --save-dev

To require the module in your application:

const Aerospike = require('aerospike')

Git Repository Installations

When using a cloned repository, install aerospike as a dependency of your application. Instead of referencing the module by name, you reference it by path.

To clone the repository use the following command:

$ git clone --recursive [email protected]:aerospike/aerospike-client-nodejs.git

Building dependancy C client

Make sure to build the C client before doing npm install variants Run the following commands to build the C client:

$ ./scripts/build-c-client.sh

Building and installing Node.js client

To install the module as a dependency of your application, run the following in the application directory:

$ npm install --unsafe-perm --build-from-source

To require it in the application:

const Aerospike = require('aerospike')

Documentation

Access the client API documentation at: https://docs.aerospike.com/apidocs/nodejs. This documentation is built from the client's source using JSDocs v3 for every release.

The API docs also contain a few basic tutorials:

• Getting Started - Connecting to an Aerospike database cluster
• Managing Aerospike connections in a Node cluster
• Handling asynchronous database operations using Callbacks, Promises or async/await

A variety of additional example applications are provided in the [examples](examples) directory of this repository.

Access backward incompatible API changes by a release at: https://developer.aerospike.com/client/nodejs/usage/incompatible.

API Versioning

The Aerospike Node.js client library follows semantic versioning. By Aerospike versioning guidelines, changes which may break backwards compatibility are indicated by an increase in the major version number. Minor, or patch releases, which are incremented only the second and third version number, are always backwards compatible.

Tests

The client includes a comprehensive test suite using Mocha. The tests can be found in the repository under test directory.

Before running the tests, you need to update the dependencies:

$ npm update

To run all the test cases:

$ npm test

Note: make sure your server has TTL enabled for the test namespace (Namespace Retention Configuration) to allow all tests to run correctly.

To run the tests and also report on test coverage:

$ npm run coverage

Benchmarks

Benchmark utilities are provided in the repository under benchmarks directory. See the benchmarks/README.md for details.
