SockJS server based on Asyncio (PEP 3156)
=========================================

`sockjs` is a `SockJS <http://sockjs.org>`_ integration for
`aiohttp <https://github.com/aio-libs/aiohttp/>`_.  SockJS interface
is implemented as a `aiohttp` route. 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.

Simple aiohttp web server is required::

   [server:main]
   use = egg:gunicorn#main
   host = 0.0.0.0
   port = 8080
   worker = aiohttp.worker.GunicornWebWorker


Example of sockjs route::

   def main(global_settings, **settings):
       app = web.Application()
       app.router.add_route('GET', '/', index)
       sockjs.add_endpoint(app, prefix='/sockjs', handler=chatSession)
       web.run_app(app)

Client side code::

  <script src="https://cdn.jsdelivr.net/npm/sockjs-client@1/dist/sockjs.min.js"></script>
  <script>
    var sock = new SockJS('http://localhost:8080/sockjs');

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

    sock.onmessage = function(e) {
      console.log('message', e.data);
      sock.close();
    };

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