NATS PHP Client
===============

[](#nats-php-client)

A PHP implementation of a client for [NATS](https://nats.io/).

🚧 Please note that this package is currently under development and not ready for general use yet.

Usage
-----

[](#usage)

Install the package using composer:

```
composer require flownative/nats

```

In PHP, open a new connection with

```
use Flownative\Nats\Connection;

// Connect to a server
$nats = new Connection(
    'nats://localhost:4222',
    [
        'username' => 'nats',
        'password' => 'password',
        'debug' => true
    ]
);

// Simple publisher
$nats->publish('foo', 'Hello World');

// Simple asynchronous subscriber
$nats->subscribe('foo', function($message) {
    printf("\nReceived a message: %s\n", $message->getBody());
});
```

This will open a new socket connection and send a CONNECT and PING to the given NATS server an do a simple PUB / SUB run:

```
 🚀  Connecting with server via nats://localhost:4222 ...
>>>> CONNECT {"lang":"php","version":"dev-master@7dd6908c3e9f26e1094873a510547cd950bcb2c7","verbose":false,"pedantic":false,"user":"nats","pass":"password"}
> PING
> SUB foo vjxX30gfutwGDBxfLuKR
>>>> PUB foo 11
Hello World
getBody()));
});

// Send a request which will be answered by the "hello" subscriber:
$nats->request(
    'hello',
    'Robert',
    function (Message $message) {
        printf("Request returned: %s\n", $message->getBody());
    }
);
```

Development
-----------

[](#development)

### Tests

[](#tests)

Unit tests can be executed with PhpUnit. A configuration file is included in the main directory. Unit tests are self-contained and don't need an actual NATS server running.

### Protocol Buffer schema for NATS Streaming

[](#protocol-buffer-schema-for-nats-streaming)

Since NATS Streaming uses Google's Protocol Buffers for its messages, we need corresponding PHP classes according to the given schema. This is defined by means of a .proto file, which retrieved from the [Go Nats Streaming project on Github](https://github.com/nats-io/go-nats-streaming/blob/master/pb/protocol.proto). Based on this file, you can automatically create corresponding PHP code using the Protocol Buffers Compiler.

[https://developers.google.com/protocol-buffers/docs/downloads](Download) and install the compiler (called "protoc")
