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



The Aerospike Node.js client supports all Node.js [LTS

releases](https://github.com/nodejs/Release#release-schedule). To download and

install the latest stable version of Node.js, visit

[nodejs.org](http://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:



```bash

npm install aerospike

```



To add `aerospike` as a dependency in _package.json_, run:



```bash

npm install aerospike --save-dev

```



To require the module in your application:

```bash

const Aerospike = require('aerospike')

```



## Usage



The following is very simple example how to create, update, read and remove a

record using the Aerospike database.



```js

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: ,

                                 //      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:



```bash

brew install openssl

```



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



```bash

# 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 [email protected]

sudo ln -s /opt/homebrew/opt/[email protected]/ /usr/local/opt/openssl;

# link here if before version 5.6.0 with [email protected]

sudo ln -s /opt/homebrew/opt/[email protected]/ /usr/local/opt/[email protected];

```



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



```bash

# When building from source before version 5.6 with [email protected]

sudo ln -s /opt/homebrew/opt/[email protected]/ /usr/local/opt/openssl;

# link here if before version 5.6.0 with [email protected]

sudo ln -s /opt/homebrew/opt/[email protected]/ /usr/local/opt/[email protected];

```



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



```bash

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 [email protected] 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:



```bash

brew install libuv

```



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



```bash

# 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:

```bash

  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:

```bash

  ./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:



```bash

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

```



To require it in the application:



```bash

const Aerospike = require('aerospike')

```



## Documentation



Access the client API documentation at:

[https://docs.aerospike.com/apidocs/nodejs](https://docs.aerospike.com/apidocs/nodejs).

This documentation is built from the client's source using [JSDocs

v4](https://www.npmjs.com/package/jsdoc) for every release.



The API docs also contain a few basic tutorials:



* [Getting Started - Connecting to an Aerospike database cluster](https://www.aerospike.com/apidocs/nodejs/tutorial-getting_started.html)

* [Managing Aerospike connections in a Node cluster](https://www.aerospike.com/apidocs/nodejs/tutorial-node_clusters.html)

* [Handling asynchronous database operations using Callbacks, Promises or `async`/`await`](https://www.aerospike.com/apidocs/nodejs/tutorial-callbacks_promises_async_await.html)



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:

### API Versioning



The Aerospike Node.js client library follows [semantic versioning](http://semver.org/).

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](http://mochajs.org). 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](https://docs.aerospike.com/server/operations/configure/namespace/retention)) to allow all tests to run correctly.



To run the tests and also report on test coverage:



    npm run coverage
