It was so hard to self-study Django channels, but this course was great because I was able to learn the concepts! I'm going to use what I learned from this course in my ongoing project to achieve great results! Thank you so much for thoroughly explaining all the channels-related knowledge throughout the entire course!

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.

It's a very interesting lecture to listen to after completing the Django basic lecture. This lecture is older, so there are differences in versions, but it's also fun to fix errors one by one for the latest version. It's fun!
What you will gain after the course

Understanding WebSocket Communication
Real-time web chat service
Life is short. Through Django/Channels in real-time web service development,
lead your business to success quickly and save your time. 💪

Lecture Topic 📖
Channels is a library that is consistently mentioned as a core Django library, even abroad. Since the release of version 1.0 in 2017 and reaching version 4.0 in November 2022, it has become a sufficiently mature library.
If you only know Channels, you can add real-time capabilities to your web services with a very small amount of code. It was unfortunate to see many people unable to do this simply because they weren't aware of Channels or couldn't find enough resources. That's why I worked hard to create this course, so that many of you can learn real-time web development more easily through this single lecture.
The Channels library inherits the philosophy of the high-productivity Django framework. It helps you reduce repetition and focus on the core. Let's learn how to correctly understand the Channels library and build a real-time WebSocket chat service with high productivity based on Channels.
By taking this course, you will gain a deep understanding of Channels and be able to quickly build real-time web services with Django's high productivity.
📢 Please read before taking the course.

Rich WebSocket Examples:
Echo messages, live blogs, and web chat
Learning Content 📚
1. Key Components of Channels
- We will summarize the core concepts of Channels.
2. (Practice) Implementing a Super Simple Echo WebSocket
- By implementing an Echo WebSocket with Channels, we open the curtain on learning Channels-based chat services.
3. (Practice) Sending and Receiving JS Objects via WebSockets
- In all communications, the process of serialization/deserialization is inevitable. We will look at common mistakes made during the serialization process in JS, and explore how to perform JSON serialization/deserialization in WebSocket clients and Channels.
4. Running and Connecting to the Redis Server
- We will look at how to integrate Redis Enterprise Cloud's Free Plan into a Django project, how to register Redis account information as environment variables, and how to efficiently load and process them in Django. Finally, we will check the commands to run a Redis server using Docker.
5. Inter-process communication using Channel Layers
- Channels supports inter-process communication through the Channel Layer. We will examine the types of backends supported by the Channel Layer and summarize its core APIs.
6. (Practice) Web Socket Liveblog
- We will create a live blog service that responds in real-time to blog post additions, edits, and deletions on the server without needing to refresh the webpage. You will be able to experience the concise and robust power of Django Channels.
7. Data types that can be sent to the channel layer
- Serialization and deserialization are inevitable in all communications. We will examine the serialization methods used in communication with the channel layer and take a detailed look at the serialization constraints within the channel layer.
8. WebSocket Reconnection
- Networks can be disconnected at any time. Even with WebSockets, which require a persistent connection, disconnections can occur at any moment. We will look into two methods for handling WebSocket reconnection.
9. Inheritance Relationship of Consumer Classes
- In Channels, the subject of request processing is the Consumer. We will examine the inheritance relationship of the Consumer classes provided by Channels and detail the roles of each.
10. Building a Real-World Chat Service
- As the core part of this course, we will create a chat service by efficiently using Django Channels.
11. Security
- As a security feature supported by Channels, it provides two types of middleware to defend against WebSocket CSRF attacks. We will examine examples of CSRF attacks and look in detail at how to configure these two middlewares.
Expected Questions Q&A 💬
Q. Are there any environmental requirements or other precautions to consider before taking the course?
As mentioned in this lecture, we do not cover setting up the development environment. For setting up the development environment, please refer to the "Preview" of the development environment setup section in <Python/Django Introduction Starting with Django Design Philosophy>, which has been made publicly available.
It is recommended to have a computer with Docker installed for installing and running Redis. Even if you are unable to install Docker, do not worry. I will show you how to use the managed Redis service from Redis Enterprise Cloud at redis.com under their Free Plan.
Q. What will I be able to do after mastering the content of this course?
You will be able to develop real-time web services with high productivity using Django.
