Phoenix Channel Authorization: Securing WebSockets with Socket State

Real-time communication in modern web applications requires strict access controls to protect sensitive data streams. This text-only course guides you through securing Phoenix channels in Elixir, showing you how to leverage socket state to restrict channel access effectively. What you'll learn: Understand the core security architecture of Phoenix channels and WebSockets; Configure token-based authentication to verify users at the socket connection level; Implement state-based authorization logic to restrict access to specific topics; Manage socket assigns to securely store and reference user permissions; Apply testing techniques to verify authorization rules and handle edge cases. You will start with foundational real-time security concepts before diving into written explanations and practical code implementations. This course is ideal for developers new to Phoenix security who want to master real-time authorization without complex setups. Read this guide to secure your real-time Phoenix applications.
