Building Twitch Overlays Using Web Technology

You can view the finished code on GitHub!

The streaming software OBS lets you use an embedded browser as an input. These means that you can use familiar web technologies to customize your Twitch overlays!

In this event, we covered:

• Using OBS's Browser source
• The tmi.js and ComfyJS JavaScript libraries for getting Twitch chat events
• Using DOM manipulation to display chat messages
• Using overflow and flexbox in CSS to get the rising chatbox feel
