To run this, you need working Node.js hosting with HTTPS enabled. Recommending free AWS EC2 tier, nginx as proxy and Let's Encrypt.

This code checks if user's name contains any from the strings in the bots.json, but skips accounts that are in allowed.json. So hoss00312 won't be banned, but any other username that contains that string will.

Register new application on Twitch.

Go to https://twitchtokengenerator.com/, select Bot Chat token, login.

Install Node.js.

Install yarn

npm i yarn -g

Make get request to https://api.twitch.tv/helix/users?login=CHANNEL_NAME
