pyramid sockjs 0.3.9

pyramid_sockjs
pyramid_sockjs is a gevent-based SockJS integration for
Pyramid. SockJS interface is implemented as a
pyramid route. pyramid_sockjs runs inside
a WSGI application rather than WSGI server. This means all of your previous WSGI/Pyramid experience will be
relevant. Its possible to create any number of different sockjs routes, ie
/__sockjs__/* or /mycustom-sockjs/*. You can provide different session implementation
and management for each sockjs route.
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(prefix='/__sockjs__')

return config.make_wsgi_app()
Client side code:
<script src="http://cdn.sockjs.org/sockjs-0.3.4.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>
