Live Chat Overlay Remote Window

The remote window for the Live Chat Overlay browser extension.

Setup

You'll need to run this on nginx with the nginx push-stream module. Follow the installation instructions to get the module running in your nginx before continuing below.

Configuring nginx

Once the push-stream module is installed, you can create a server block for this website.

Download this entire repo into a folder such as /web/sites/live-chat-overlay-remote, and configure an nginx server block to point to the public folder in the repo. Enable the push-stream module publisher and subscriber using the configuration below.

server {
  listen       *:443 ssl http2;
  server_name  chat.example.com;

  ssl_certificate /etc/letsencrypt/live/chat.example.com/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/chat.example.copm/privkey.pem;

  root /web/sites/live-chat-overlay-remote/public;
  index index.html;

  location /overlay/pub {
    add_header 'Access-Control-Allow-Origin' '*';
    push_stream_publisher admin;
    push_stream_channels_path    $arg_id;
  }

  location /overlay/sub {
    add_header 'Access-Control-Allow-Origin' '*';
    push_stream_subscriber eventsource;
    push_stream_channels_path    $arg_id;
    push_stream_message_template                "{\"id\":~id~,\"channel\":\"~channel~\",\"text\":~text~}";
    push_stream_ping_message_interval           10s;
  }

}

That's it! No server-side code environment is needed as the project is static HTML and JavaScript.

Browser Extension Configuration

In your Live Chat Overlay extension, set the remote URL to the path of the "overlay" folder in this project, for example: https://chat.example.com/overlay/. The extension will use that full URL as the main browser source URL, and the extension will expect the pub path to exist where it will be pushing the chat messages to.
