=== Understanding the Phoenix Architecture === Phoenix follows a convention-over-configuration approach, allowing developers to focus on building their application rather than spending time on initial setup. Here are the key components of a Phoenix application: * **Controllers:** Controllers handle incoming requests and define actions to be executed. They provide a way to interact with the application's models and render views. * **Views:** Views are responsible for rendering templates and generating HTML responses. They allow for the separation of concerns between the data fetching and the presentation logic. * **Schemas and Models:** Schemas define the structure and validation rules for data entities, while models interact with the database. Ecto, the database wrapper used in Phoenix, provides powerful features for working with databases. * **Channels:** Channels enable real-time communication between the server and the client using WebSockets. They allow for bidirectional data flow and facilitate the development of interactive and responsive applications. * **Routing:** The router maps incoming requests to the appropriate controller actions. Phoenix provides a clean and intuitive routing system that supports RESTful conventions.
