phpnats

Introduction

A PHP client for the NATS messaging system. This fork of phpnats by repejota that supports more recent versions of NATS (2.2.0-beta) and contains little improvements to fit more into PHP7 world.

Requirements

• php 7.1+
• gnatsd

Usage

Installation

Let's start by downloading composer into our project dir:

curl -O http://getcomposer.org/composer.phar
chmod +x composer.phar

Now let's tell composer about our project's dependancies, in this case, PHPNats. The way we do this is by creating a composer.json file, and placing it in the root folder of our project, right next to composer.phar

{
  "require": {
    "workfront/nats": "^2.2.3"
  }
}

Let's let Composer work its magic:

php composer.phar install

Composer will download all the dependencies defined in composer.json, and prepare all the files needed to autoload them.

Basic Usage

$client = new \Nats\Connection();
$client->connect();

// Publish Subscribe

// Simple Subscriber.
$client->subscribe(
    'foo',
    function ($message) {
        printf("Data: %s\r\n", $message->getBody());
    }
);

// Simple Publisher.
$client->publish('foo', 'Marty McFly');

// Wait for 1 message.
$client->wait(1);

// Request Response

// Responding to requests.
$sid = $client->subscribe(
    'sayhello',
    function ($message) {
        $message->reply('Reply: Hello, '.$message->getBody().' !!!');
    }
);

// Request.
$client->request(
    'sayhello',
    'Marty McFly',
    function ($message) {
        echo $message->getBody();
    }
);

Encoded Connections

$encoder = new \Nats\Encoders\JSONEncoder();
$options = new \Nats\ConnectionOptions();
$client = new \Nats\EncodedConnection($options, $encoder);
$client->connect();

// Publish Subscribe

// Simple Subscriber.
$client->subscribe(
    'foo',
    function ($payload) {
        printf("Data: %s\r\n", $payload->getBody()[1]);
    }
);

// Simple Publisher.
$client->publish(
    'foo',
    [
     'Marty',
     'McFly',
    ]
);

// Wait for 1 message.
$client->wait(1);

// Request Response

// Responding to requests.
$sid = $client->subscribe(
    'sayhello',
    function ($message) {
        $message->reply('Reply: Hello, '.$message->getBody()[1].' !!!');
    }
);

// Request.
$client->request(
    'sayhello',
    [
     'Marty',
     'McFly',
    ],
    function ($message) {
        echo $message->getBody();
    }
);

Developer's Information

Releases

• Latest stable

• Latest dev

• PHPNats on Packagist

Tests

Tests are in the tests folder. To run them, you need PHPUnit and execute make test-tdd.

We also have a BDD test suite under the spec folder. To run the suite, you need PHPSpec and execute make test-bdd.

You can also execute the all suites ( TDD + BDD ) with make test.

Code Quality

We are using PHP Code Sniffer to ensure our code follow an high quality standard.

To perform an analysis of the code execute make lint.

There is currently three steps when we lint our code:

• First we lint with php itself php -l
• Then we lint with PSR2 standard
• And finally we lint with a custom ruleset.xml that checks dockblocks and different performance tips.
