Event Callbacks

The Unleash Python client support event callbacks!

1. Create a function with the type Callable[[UnleashEvent]] and pass it to the Unleash client at initialization.
2. Enable impression data on feature flag configuration.

Example code using blinker:

from blinker import signal
from UnleashClient import UnleashClient
from UnleashClient.events import UnleashEvent

send_data = signal('send-data')

@send_data.connect
def receive_data(sender, **kw):
    print("Caught signal from %r, data %r" % (sender, kw))
    return kw

def example_callback(event: UnleashEvent):
    send_data.send('anonymous', data=event)

# Set up Unleash
client = UnleashClient(
    "https://unleash.herokuapp.com/api",
    "My Program"
    event_callback=example_callback
)
client.initialize_client()
client.is_enabled("testFlag")
