In this fast-paced, practical course, you’ll create private and group chat rooms with features like live messaging, user presence, unread notifications, and file attachments. You’ll also manage authentication, user roles, and permissions — all in real time.
We’ll use modern Rails tools and technologies, including:
- Devise for authentication
- ActionCable & WebSockets for bi-directional, live communication
- Redis for real-time unread notification counts as the database and as the Pub/Sub broker for all data updates
- Stimulus JS for dynamic frontend behavior
- Active Storage for uploading avatars and sharing files
- Polymorphic associations and other advanced ActiveRecord patterns
- Rails Channels and WebSocket lifecycle hooks to track user online/offline status in real time.
You’ll also learn how to:
- Build real-time group membership and role systems
- Secure Group Page from Unauthorized Visits on Server and Client Side in Real Time
- Display last messages and unread message counts — instantly
Throughout the course, we’ll explain complex backend logic using visual diagrams and schemas to make everything clear and digestible.
This course is compact and efficient — just around 6 hours — carefully designed to save your time and deliver only the most relevant, high-impact knowledge. Each lecture builds directly on the last, so it’s important to follow in sequence for a smooth learning experience.
Who is this course for?
This course is perfect for Rails developers with basic knowledge of MVC, routing, and RESTful APIs, who want to go beyond CRUD and build something dynamic and production-ready. Familiarity with JavaScript will also help, as we’ll use Stimulus JS for frontend interactions.
