pip install -r requirements/core.txt

Use the client in your code:

import asyncio
from concurrent.futures import ThreadPoolExecutor

from phx_events.client import PHXChannelsClient
from phx_events.phx_messages import ChannelMessage, Event, Topic


def print_handler(message: ChannelMessage, client: PHXChannelsClient) -> None:
    client.logger.info(f'DEFAULT: {message=}')


async def async_print_handler(message: ChannelMessage, client: PHXChannelsClient) -> None:
    client.logger.info(f'ASYNC: {message=}')


async def main() -> None:
    token = 'auth_token'
    client: PHXChannelsClient

    with ThreadPoolExecutor() as pool:
        async with PHXChannelsClient(token) as client:
            client.register_event_handler(
                event=Event('event_name'),
                handlers=[
                    print_handler,
                    async_print_handler,
                ],
            )
            client.register_topic_subscription(Topic('topic:subtopic'))

            await client.start_processing(pool)


if __name__ == '__main__':
    asyncio.run(main(), debug=True)
