This example uses the asyncio SSE library: https://github.com/brutasse/asyncio-sse
import asyncio
import sse
class Handler(sse.Handler):
@asyncio.coroutine
def handle_request(self):
yield from asyncio.sleep(2)
self.send('foo')
yield from asyncio.sleep(2)
self.send('bar', event='wakeup')
start_server = sse.serve(Handler, 'localhost', 8888)
asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()
