./sse-emit-ping in another terminal

./sse-get-time


py4web with socketio examples


cp mlvsio to apps/

( chan_sio.py - uvicorn channel server )

cd apps/mlvsio && ./chan_sio.py

run py4web

firefox localhost:8000/mlvsio


flvsio is mlvsio with tornado-socketio and sockjs-example

added celery longrun_task from

https://matthewminer.com/2015/02/21/pattern-for-async-task-queue-results

( To test it, you need to run the file . worker.sh )

socketio events moved to wsservers.py

copy flvsio/wsservers.py to py4web/utils/wsservers.py

( you can remove twisted and aiohttp from the wsservers.py, you need install packages from wsservers.py )

./py4web.py run -s tornadoSioWsServer apps

(If the py4web.py cannot find the server tornadoSioWsServer, it means you have not installed all the packages from the file wsservers.py)

Note - the name of the application (flvsio) is used in the name of the redis-channel in the server file wsservers.py

firefox localhost:8000/flvsio


lvsio - demo for "how to push event to js-UI from py4web-controllers.py"

cp lvsio to apps/

( chan_sio.py - uvicorn channel server )

cd apps/lvsio && ./chan_3000.py

run py4web

firefox localhost:8000/lvsio


redis must be installed and running
