Nymph PubSub Server - collaborative app data

Powerful object data storage and querying for collaborative web apps.

Deprecation Notice

The PHP implementation of Nymph/Tilmeld has been deprecated. It will no longer have any new features added. Instead, a new version of Nymph running on Node.js, written entirely in TypeScript will replace the PHP implementation. You can find it over at the Nymph.js repo.

Installation

Automatic Setup

The fastest way to start building a Nymph app is with the Nymph App Template.

Manual Installation

composer require sciactive/nymph-pubsub

This repository is the PHP publish/subscribe server. For more information, you can see the main Nymph repository.

Usage

// pubsub.php: Start with `php pubsub.php [-d]`

if (php_sapi_name() != "cli") {
  die("You can only run pubsub.php from the command line.");
}

// This is an example server that is configured with hostname
// "pubsubnetwork1entry" as an entry point to network1, which contains two
// endpoint servers, "pubsubnetwork1endpoint1" and "pubsubnetwork1endpoint2".

// Setting a default timezome is highly recommended.
date_default_timezone_set('America/Los_Angeles');

require 'vendor/autoload.php';

// Set up Nymph.
use Nymph\Nymph;
Nymph::configure([
  'MySQL' => [
    'host' => 'your_db_host',
    'database' => 'your_database',
    'user' => 'your_user',
    'password' => 'your_password'
  ]
]);

\Nymph\Nymph::connect();

// Allow this file to be called with "-d" to daemonize it.
if (in_array('-d', $argv)) {
  function shutdown() {
    posix_kill(posix_getpid(), SIGHUP);
  }

  // Switch over to daemon mode.
  if ($pid = pcntl_fork()) {
    return;
  }

  register_shutdown_function('shutdown');
} else {
  error_reporting(E_ALL);
}

// Set up Nymph PubSub.
$config = include(__DIR__.'/pubsub-config.php');
$config['port'] = 8080;
$config['relays'] = [
  'ws://pubsubnetwork1endpoint1:8080/',
  'ws://pubsubnetwork1endpoint2:8080/'
];
$server = new \Nymph\PubSub\Server($config);

// Run the server.
$server->run();

// pubsub-config.php

// This config file tells Nymph to publish entity updates to these network entry
// points. They will then relay the publish to their network.

return [
  'entries' => [
    'ws://pubsubnetwork1entry:8080/',
    'ws://pubsubnetwork2entry:8080/',
    'ws://pubsubnetwork3entry:8080/'
  ]
];

// somewhere in your Nymph rest endpoint.
$config = include('path/to/pubsub/pubsub-config.php');
\Nymph\PubSub\Server::configure($config);
