API

YouTubeWatch.constructor(options)

options is an object that you may write your own properties to. The following properties are read by YouTubeWatch:

  • secret - A private key used by Pubsubhubbub, it is not required to include this property but it is highly recommended that you do. Defaults to 'change me!'
  • hubCallback - Your ip/domain name that will be used as a callback URL by Pubsubhubbub. It must be in a URL format, ex: 'http://example.com/'. This is a required property as the default is undefined.
  • hubPort - The port Pubsubhubbub will listen on. This must be an open port on your system. Defaults to port 9001.
  • hubUrl - The URL in which we listen to updates from. This shouldn't be changed unless you know what you're doing.

YouTubeWatch.start()

This function will start the internal service used by Pubsubhubbub. If the service successfully starts up then the start event is emitted otherwise the error event is. Once the start event has been sent you may begin to watch for channel updates via the YouTubeWatch.watch() function. If this function is called while the service has already been start an error is emitted.

YouTubeWatch.stop()

This functions will stop the internal service. After it has been stopped a stop event is emitted. If the service is not running and this function is called then an error is emitted.

YouTubeWatch.watch(channels=[])

Watches a list of channels IDs. Channels may either be a string or an array of strings. After each successful channel has been verified to receive updates a watch event is ommited.

YouTubeWatch.unwatch(channels=[])

Removes the watch state from a list of channel IDs. Channels may either be a string or an array of strings. After each successful channel has been verified to stop receiving updates an unwatch event is ommited.
