PubSub#

This is a full implementation of the PubSub API of twitch. PubSub enables you to subscribe to a topic, for updates (e.g., when a user cheers in a channel).

Read more about it on the Twitch API Documentation.

Note

You always need User Authentication while using this!

Code Example#

from twitchAPI.pubsub import PubSub
from twitchAPI.twitch import Twitch
from twitchAPI.helper import first
from twitchAPI.type import AuthScope
from twitchAPI.oauth import UserAuthenticator
import asyncio
from pprint import pprint
from uuid import UUID

APP_ID = 'my_app_id'
APP_SECRET = 'my_app_secret'
USER_SCOPE = [AuthScope.WHISPERS_READ]
TARGET_CHANNEL = 'teekeks42'

async def callback_whisper(uuid: UUID, data: dict) -> None:
    print('got callback for UUID ' + str(uuid))
    pprint(data)


async def run_example():
    # setting up Authentication and getting your user id
    twitch = await Twitch(APP_ID, APP_SECRET)
    auth = UserAuthenticator(twitch, [AuthScope.WHISPERS_READ], force_verify=False)
    token, refresh_token = await auth.authenticate()
    # you can get your user auth token and user auth refresh token following the example in twitchAPI.oauth
    await twitch.set_user_authentication(token, [AuthScope.WHISPERS_READ], refresh_token)
    user = await first(twitch.get_users(logins=[TARGET_CHANNEL]))

    # starting up PubSub
    pubsub = PubSub(twitch)
    pubsub.start()
    # you can either start listening before or after you started pubsub.
    uuid = await pubsub.listen_whispers(user.id, callback_whisper)
    input('press ENTER to close...')
    # you do not need to unlisten to topics before stopping but you can listen and unlisten at any moment you want
    await pubsub.unlisten(uuid)
    pubsub.stop()
    await twitch.close()

asyncio.run(run_example())

Class Documentation#

class twitchAPI.pubsub.PubSub#

Bases: object

The PubSub client

__init__(twitch, callback_loop=None)#
Parameters:
  • twitch (Twitch) – A authenticated Twitch instance

  • callback_loop (Optional[AbstractEventLoop]) –

    The asyncio eventloop to be used for callbacks.

    Set this if you or a library you use cares about which asyncio event loop is running the callbacks. Defaults to the one used by PubSub.

logger: Logger#

The logger used for PubSub related log messages

ping_frequency: int#

With which frequency in seconds a ping command is send. You probably don’t want to change this. This should never be shorter than 12 + ping_jitter seconds to avoid problems with the pong timeout.

Default: 120

ping_jitter: int#

time in seconds added or subtracted from ping_frequency. You probably don’t want to change this.

Default: 4

listen_confirm_timeout: int#

maximum time in seconds waited for a listen confirm.

Default: 30
