Frequently Asked Questions

Why is ngrok used in this package?

ngrok is used to expose the local server to the internet. This is necessary because the webhook URL must be accessible from the internet. If you don’t provide callback_url to the constructor of the YouTubeNotifier or AsyncYouTubeNotifier, the notifier will use ngrok to expose the local server to the internet. It’s useful for development purposes.

What are the differences between YoutubeNotifier and AsyncYoutubeNotifier?

Their usage is very similar, except that the AsyncYouTubeNotifier has serve() method instead of run() method. Following are the differences between them:

YouTubeNotifier

• Public methods are synchronous.

• run() method can be run in a sub-thread.

• Creates a new asyncio event loop and runs the notifier in it.

AsyncYouTubeNotifier

• Public methods are asynchronous.

• serve() method can only be run in the main thread.

• Serves in the existing asyncio event loop.

To see the difference in usage between them, see the sync.py and async.py examples.
