This plugin will allow users to chat with the website’s business in real-time by using Facebook Messenger. Users can start a conversation on the website and continue it on other devices at any time.
Please note, Facebook is still currently developing their Customer Chat and so it is still in beta.

<h3>WebSocket Server Setup (Linux with SSL)</h3>
<ol>
<li>
Create a systemd service file: 
<code>bash 
sudo vim /etc/systemd/system/websocket_server.service</code>
</li>
<li>
Paste the following content: 
<code>bash 
[Unit] 
Description=WebSocket Server for NS Chat (SSL) 
After=network.target 
[Service] 
ExecStart=/usr/bin/php /file/to/path/yourdomain/wp-content/plugins/ns-chat/server.php start 
Restart=always 
RestartSec=25 
User=www-data 
Group=www-data 
StandardOutput=file:/var/log/websocket_server.out.log 
StandardError=file:/var/log/websocket_server.err.log 
[Install] 
WantedBy=multi-user.target</code>
</li>
<li>
Add SSL context in <code>server.php</code>: 
<code>php 
$context = [ 
'ssl' => [ 
 'local_cert' => '/path/to/file.crt', 
 'local_pk' => '/path/to/file.key', 
 'verify_peer' => false, 
] 
];</code>
</li>
<li>
Set permissions for plugin folder: 
<code>bash 
sudo chown -R www-data:www-data /path/to/ns-chat/ 
sudo chmod -R 775 /path/to/ns-chat/</code>
</li>
<li>
Reload and start the daemon: 
<code>bash 
sudo systemctl daemon-reload 
sudo systemctl enable websocket_server --now 
sudo systemctl restart websocket_server 
sudo systemctl status websocket_server</code>
</li>
<li>
Check logs if needed: 
<code>bash 
/var/log/websocket_server.out.log 
/var/log/websocket_server.err.log</code>
</li>
</ol>
<h3>Custom Port Configuration</h3>
By default, the WebSocket server listens on port 2346.
To use a different port:
<ol>
<li>Change the port in <code>server.php</code>: 
<code>php 
$wsWorker = new Worker('websocket://0.0.0.0:2346', $context);</code></li>
<li>
Change the port in <code>ns-chat.php</code>: 
<code>php 
$ws_port = 2346;</code>
</li>
<li>
You can check and change the port in <code>chat-ui.js</code>: 
<code>js 
const port = nschat_data.wsPort || 2346;</code>
</li>
<li>
If the port is closed, then open a new port on your server’s firewall: 
<code>bash 
sudo ufw allow <your-port>/tcp 
sudo firewall-cmd --permanent --add-port=<your-port>/tcp 
sudo firewall-cmd --reload 
sudo iptables -A INPUT -p tcp --dport <your-port> -j ACCEPT 
sudo iptables-save > /etc/iptables/rules.v4</code>
</li>
</ol>
<h3>Database Tables</h3>
The plugin creates and uses the following tables:
<ul>
<li><code>wp_ns_chat_dialogues</code></li>
<li><code>wp_ns_chat_messages</code></li>
<li><code>wp_ns_chat_users</code></li>
</ul>
Tables are created and populated automatically on plugin activation.
<h3>User Synchronization</h3>
<ol>
<li>Initial migration of all users from <code>wp_users</code> to <code>wp_ns_chat_users</code> on plugin activation.</li>
<li>New registrations are handled by: 
<code>php 
add_action('user_register', 'ns_chat_add_user_on_registration');</code></li>
<li>Profile updates are synced via: 
<code>php 
add_action('profile_update', 'ns_chat_update_user_data');</code> 
You may bind these functions to custom hooks based on your app’s logic.</li>
</ol>
