README

Latest Stable Version Build Status Codecov

This repository contains the codebase bridge for broadcast RoadRunner plugin.

Installation

To install application server and broadcast codebase

$ composer require spiral/roadrunner-broadcast

You can use the convenient installer to download the latest available compatible version of RoadRunner assembly:

$ composer require spiral/roadrunner-cli --dev
$ vendor/bin/rr get

Usage

For example, such a configuration would be quite feasible to run:

rpc:
  listen: tcp://127.0.0.1:6001

server:
  # Don't forget to create a "worker.php" file
  command: "php worker.php" 
  relay: "pipes"

http:
  address: 127.0.0.1:80
  # Indicate that HTTP support ws protocol
  middleware: [ "websockets" ]

websockets:
    broker: default
    path: "/ws"

broadcast:
    default:
        driver: memory

Read more about all available brokers on the documentation page.

After configuring and starting the RoadRunner server, the corresponding API will become available to you.

<?php

use Spiral\Goridge\RPC\RPC;
use Spiral\RoadRunner\Broadcast\Broadcast;

require __DIR__ . '/vendor/autoload.php';

$broadcast = new Broadcast(RPC::create('tcp://127.0.0.1:6001'));

if (!$broadcast->isAvailable()) {
    throw new \LogicException('The [broadcast] plugin not available');
}

//
// Now we can send a message to a specific topic
//
$broadcast->publish('channel-1', 'message for channel #1');

Select Specific Topic

Alternatively, you can also use a specific topic (or set of topics) as a separate entity and post directly to it.

// Now we can select the topic we need to work only with it
$topic = $broadcast->join(['channel-1', 'channel-2']);

// And send messages there
$topic->publish('message');
$topic->publish(['another message', 'third message']);

Read more about all the possibilities in the documentation page.

Client

In addition to the server (PHP) part, the client part is also present in most projects. In most cases, this is a browser in which the connection to the server is made using the WebSocket protocol.

const ws = new WebSocket('ws://127.0.0.1/broadcast');

ws.onopen = e => {
    const message = {
        command: 'join',
        topics:  ['channel-1', 'channel-2']
    };

    ws.send(JSON.stringify(message));
};

ws.onmessage = e => {
    const message = JSON.parse(e.data);

    console.log(`${message.topic}: ${message.payload}`);
}
