Unified Endpoints in nginx-push-stream

I recently started playing with nginx-push-stream-module. This a really cool module that essentially allows you to replicate the basic functionality of Pusher and PubNub within nginx.

The configuration is pretty basic:

Publisher

location ~ /pub/(.+) {
    internal;
    push_stream_publisher admin;
    push_stream_channels_path $1;
}  

Subscriber

location ~ /sub/(.+) {
    internal;
    push_stream_subscriber;
    push_stream_channels_path $1;
    push_stream_message_template ~text~\n;
}

WebSocket publisher/subscriber

  location ~ /ws/(.+) {
    internal;
    push_stream_subscriber websocket;
    push_stream_websocket_allow_publish on;
    push_stream_ping_message_interval 10s;
    push_stream_channels_path $1;
    push_stream_message_template ~text~\n;
  }

Unified PubSub endpoint

location ~ /chan/([\w\d\-_:]+)$ {
    set $chan $1;

    if ($http_upgrade ~ "websocket") {
      rewrite ^ /ws/$chan last;
    }

    if ($request_method = "GET") {
      rewrite ^ /sub/$chan last;
    }

    if ($request_method = "POST") {
      rewrite ^ /pub/$chan last;
    }

}

Usage

Publisher

$ curl -s -X POST -d "Hello World" https://streamboat.tv/chan/mychan

Subscriber

$ curl -s https://streamboat.tv/chan/mychan
Hello World

JS pub/sub

var ws = new WebSocket("wss://streamboat.tv/chan/mychan");
ws.onmessage = function(event) {
    console.log(event.data);
}
// Hello World
