I've looked for videos and lectures related to Django Channels, but I haven't found any lectures as helpful as this one. The content covers a lot and moves quickly, so you can't let your mind wander even for a moment, making it hard to watch in a relaxed state. However, it's been extremely helpful because it teaches the necessary feature implementations for WebSocket authentication and building actual chat services. While these might be issues you could resolve through direct implementation using searches or ChatGPT, there's a lot of content that's good to know in advance.
