bolt
====

[](#bolt)

Asynchronous WebSocket client client library for PHP. Supports HyBi, as well as Hixie #76 (no point).

This was built purely to be a client, as the majority of the WS clients available also contain servers and are very bloated.

Installation
============

[](#installation)

Using composer:

```
composer require calcinai/bolt

```

Usage
=====

[](#usage)

Since this really lends itself to being an asynchronous app, it is built to use the React event loops and resolver since there's a good chance they'll be in your project already and this lets you attach to the same loop.

```
$loop = \React\EventLoop\Factory::create();
$dns_factory = new React\Dns\Resolver\Factory();
$resolver = $dns_factory->createCached('8.8.8.8', $loop);

$client = new \Calcinai\Bolt\Client('ws://127.0.0.1:1337/chat', $loop, $resolver);

//Most WS servers will complain/forbid if there is no origin header
$client->setOrigin('127.0.0.1');

$client->connect();

$client->on('stateChange', function($newState){
    echo "State changed to: $newState\n";
});

$client->on('message', function($message) use ($client){
    echo "New message: \n";
    echo $message;

    $client->send('This is a response message');
});

$loop->run();
```

Other available events are `connecting`, `connect`, `disconnecting`, `disconnect`

HTTP basic auth is also supported via the URI inf the form `user:pass@host`

Any feedback is most welcome
