Script to automatically add videos from a Youtube channel to a user playlist
Once specified a Youtube channel as input and a playlist as output, it gives the option to add videos in chronological order (starting from a page token, since the API returns max 50 videos per request; if no page token is specified it starts from the newest videos).
There's also an option to add videos specifying the IDs directly.
The HTML must be started in a running web server environment like node.js, since the Google Sign In API won't work otherwise.
