I’ve been checking out this forum for a while now. Really great stuff, although a bit too technical for me at times. (just doing this as a hobby)
As a finisher for the book programming phoenix i made a small app which also uses the youtube api. Its basically just a genserver grabbing a new video when the currently playing video has ended. The video playing is synced to all users through the use of channels.
It took me a while to understand the concept of genservers but eventually i (kind of) figured it out
