I am trying to check if someone is live on twitch, and depending on their stream status put it in my website.

I have tried this website https://api.twitch.tv/kraken/streams/YOUR_CHANNEL_NAME that supposedly checks if someone is live, but the api is outdated if I’m not mistaken, I also found a tutorial for this, but for php, which i do not want to use.
I was wondering if someone could help me with this question.
