The *EventSource** interface is used to receive server-sent events. It connects

to a server over HTTP and receives events in text/event-stream format without

closing the connection. *aiohttp-sse* provides support for server-sent

events for aiohttp_.

Installation

------------

Installation process as simple as::

    $ pip install aiohttp-sse

Mailing List

------------

*aio-libs* google group: https://groups.google.com/forum/#!forum/aio-libs

Example

-------

.. code:: python

    import asyncio

    from aiohttp import web

    from aiohttp.web import Response

    from aiohttp_sse import sse_response

    from datetime import datetime

    async def hello(request):

        loop = request.app.loop

        async with sse_response(request) as resp:

            while True:

                data = 'Server Time : {}'.format(datetime.now())

                print(data)

                await resp.send(data)

                await asyncio.sleep(1)

        return resp

    async def index(request):

        d = """

            

            

                

                    var evtSource = new EventSource("/hello");

                    evtSource.onmessage = function(e) {

                        document.getElementById('response').innerText = e.data

                    }

                

                
Response from server:

                


            

        

        """

        return Response(text=d, content_type='text/html')


    app = web.Application()

    app.router.add_route('GET', '/hello', hello)

    app.router.add_route('GET', '/', index)
