django channels private chat

Question

I am creating a Django private chat application using Django channels. I am facing a problem with Redis. someone told me that Redis is not supported in Windows OS. Can anyone have an alternate?

settings.py Channel_layer

CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [("localhost", 6379)],
        },
    },
}

and error shown is

Answer 1

You can download ubuntu for windows, than run redis server from ubuntu terminal - works well.

Answer 2

You can use In Memory Channel Layer for development on windows.

Though is not encouraged for use in production.

CHANNEL_LAYERS = {
    'default': { 
        "BACKEND": "channels.layers.InMemoryChannelLayer"
    },
}
