Aerospike Node.js Client codecov npm downloads

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

The client is compatible with Node.js 23, Node.js 22, (LTS), Node.js 20 (LTS),and 18 (LTS). It supports the following operating systems:

  • RHEL 8/9
  • Debian 11
  • Amazon Linux 2023
  • Ubuntu 20.04/22.04/24.04 (Focal Fossa, Jammy Jellyfish, Noble Numbat)
  • Many Linux distributions compatible with one of the above OS releases.
  • macOS 12/13/14

The client is compatible with arm64, aarch64, and x86_64 architectures.

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.

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.

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')

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 AEROSPIKE SERVER NODE HERE!
const config = {
  hosts: '192.168.33.10:3000',
}

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 dependent on server location. 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()
    }
  })

macOS

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

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

OpenSSL Library OpenSSL is needed to build the Aerospike C Client. If downloading from NPM at version 5.6.0 or later, you will not need to have OpenSSL installed to use the Aerospike Nodejs Client. If you are using version 5.5.0 and below, you will need to do some additional linking to use the client, which is specified below.

We recommend using brew to install OpenSSL:

brew install openssl

For a Mac using ARM architecture, OpenSSL should be linked as shown below:

# When building from source before version 5.6 with openssl@3
sudo ln -s /opt/homebrew/opt/openssl@3/ /usr/local/opt/openssl;
# link here if before version 5.6.0
sudo ln -s /opt/homebrew/opt/openssl@3/ /usr/local/opt/openssl@3;

# When building from source with openssl@1.1
sudo ln -s /opt/homebrew/opt/openssl@1.1/ /usr/local/opt/openssl;
# link here if before version 5.6.0 with openssl@1.1
sudo ln -s /opt/homebrew/opt/openssl@1.1/ /usr/local/opt/openssl@1.1;

For a Mac using X86 architecture, OpenSSL should be linked as shown below:

# When building from source before version 5.6 with openssl@1.1
sudo ln -s /opt/homebrew/opt/openssl@1.1/ /usr/local/opt/openssl;
# link here if before version 5.6.0 with openssl@1.1
sudo ln -s /opt/homebrew/opt/openssl@1.1/ /usr/local/opt/openssl@1.1;

Before version 5.6.0, you may need to some add some variables to your profile for OpenSSL to be found.

export PATH="/usr/local/bin/:/usr/local/opt/openssl/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"  
export EXT_CFLAGS="-I/usr/local/opt/openssl/include"
# Make sure to source the changes to your shell profile
source ~/.bashrc
source ~/.profile
source ~/.zshrc

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

LIBUV Library

Libuv is needed to build the Aerospike C Client. If downloading from NPM at version 5.6.0 or later, you will not need to have Libuv installed to use the Aerospike Nodejs Client. If you are using version 5.5.0 and below, you will need to do some additional linking to use the client, which is specified below.

We recommend using brew to install Libuv:

brew install libuv

For a Mac using ARM architecture, Libuv should be linked as shown below:

# When building from source before version 5.6
sudo ln -s /opt/homebrew/opt/libuv/ /usr/local/opt/libuv;

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 git@github.com: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 v4 for every release.

The API docs also contain a few basic tutorials:

A variety of additional example applications are provided in the 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.
