How to use redis combine with flask-socketio

[xiazhibin]

In flask, I can init flask_redis as an extension redis.init_app(app), and use redis.set(key, value) every flask request,
But in flask-socketIO, I have no idea with it.how to init and how to use.
For I want to record some player state in redis

Is this right?

from flask_redis import FlaskRedis

app = Flask(__name__)
app.config['SECRET_KEY'] = 'asdfasdf'
socketio = SocketIO(app)
redis = FlaskRedis(app)

@socketio.on('connect')
def test_connect(auth):
    redis.set(request.sid, "alive")
    emit('message', {'data': 'Connected'})

@socketio.on('message')
def test_connect(data):
    state = redis.get(request.sid)
    emit('message', {'data': state})

socketio.run(app)

Are you reading the documentation? https://flask-socketio.readthedocs.io/en/latest/deployment.html#using-multiple-workers

Thanks for reply ! But I am not using Multiple Workers, but just want to use redis to save data as DB

[miguelgrinberg]

The only use that this package makes of Redis is for multiple workers and for emitting from external processes. Any other thing you want to do with Redis is unrelated to this package.

So I can use redis just like other flask application as?
I am concern about the thread safe problem with eventlet when using redis and socketIO

[miguelgrinberg]

Okay, that is between eventlet and redis, it has nothing to do with this package. In general monkey-patching is required for this.
