pyramid_sockjs 0.2

SockJS server implementation for Pyramid.

Pyramid SockJS

Gevent-based SockJS integration for Pyramid. SockJS interface is implemented as pyramid route. It runs inside wsgi app rather than wsgi server. Its possible to create any number of different sockjs routes, ie /__sockjs__/* or /mycustom-sockjs/*. also you can provide different session implementation and management for each of sockjs routes.

Gevent based server is required for pyramid_sockjs. For example gunicorn with gevent worker. pyramid_sockjs provides simple gevent based paster server runner:

[server:main]
use = egg:pyramid_sockjs#server
host = 0.0.0.0
port = 8080

Example of sockjs route:

def main(global_settings, **settings):
    config = Configurator(settings=settings)
    config.add_sockjs_route()

    return config.make_wsgi_app()

Client side code:

<script src="http://cdn.sockjs.org/sockjs-0.2.min.js"></script>
<script>
    var sock = new SockJS('http://localhost:8080/__sockjs__');

    sock.onopen = function() {
      console.log('open');
    };

    sock.onmessage = function(obj) {
      console.log(obj);
    };

    sock.onclose = function() {
      console.log('close');
    };
</script>
