socker 1.2

redis pubsub websocket proxy

socker runs as a single-process service, using asyncio for non-blocking I/O.

socker uses a single redis pubsub channel, and has its own channel subscription logic, this means that you may share redis database with other applications.

socker runs as a single-process service. socker opens up a websocket server port and establishes a redis connection. The redis connection creates a subscription on the socker channel.

Installation

pip install socker

Usage

$ socker -h
Start the socker websocket server

  socker [options]
  socker -? | --help
  socker --version

  -i INTERFACE    Listening interface [default: localhost]
  -p PORT         Listening port [default: 8765]

  -v              Enable verbose output

  --redis-host=HOST             Redis host [default: localhost]
  --redis-port=PORT             Redis port [default: 6379]
  --redis-db=DB                 Redis database [default: 0]

To publish a message to socker from another application:

from socker import Message


channel = 'foo.bar.42'
data = {
    'yes': [
        'yes',
        'no',
        'baz'
    ]
}

redis_client.publish('socker', Message(channel, data))

Any websocket clients subscribed to

• foo.*

• foo.bar.*

• foo.bar.42

will receive that message.
