SockJS server based on Asyncio (PEP 3156)

aiosockjs is a SockJS server based on aiohttp PEP 3156 asyncio module.

aiosockjs is a SockJS integration for 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(loop=loop)
    app.router.add_route('GET', '/', index)
    sockjs.add_endpoint(app, prefix='/sockjs', handler=chatSession)

    handler = app.make_handler()
    srv = loop.run_until_complete(
        loop.create_server(handler, '127.0.0.1', 8080))
    print("Server started at http://127.0.0.1:8080")
    try:
        loop.run_forever()
     except KeyboardInterrupt:
        srv.close()
        loop.run_until_complete(handler.finish_connections())

Client side code:

<script src="//cdn.jsdelivr.net/sockjs/0.3.4/sockjs.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>

Installation

1. Install virtualenv:

   $ wget https://raw.github.com/pypa/virtualenv/master/virtualenv.py
   $ python3.4 ./virtualenv.py --no-site-packages sockjs
   

3. Clone aiosockjs from github and then install:

   $ git clone https://github.com/aio-libs/sockjs.git
   $ cd sockjs
   $ ../sockjs/bin/python setup.py develop
   

To run chat example use following command:

$ ./sockjs/bin/python ./aiosockjs/examples/chat.py
