Hello friends!
I recently completed my Twitch.Tv project, but with the recent changes in the API I don’t know if what I done is valid. I hard-coded the demo JSON and hosted on a personal server. I tried to keep the original idea, but as the suggested API doesn’t show if streamers are online, this was the solution I found.
I hosted this specific project on GitHub because Twitch was blocking the access from CodePen.
Project: https://michelmarechal.github.io/twitchviewer/
Code: https://github.com/michelmarechal/twitchviewer
Your feedback will be very much appreciated 
Edit: I managed to make it work reading the API guide again.
