Front Controller: The Pattern That Unifies Your Web Application's Entry Point
The article discusses the Front Controller pattern, which serves as a unified entry point for web applications. It highlights the problem of duplicated code across multiple API endpoints and how the Front Controller can streamline request handling. The implementation example provided uses Python's standard library to demonstrate the pattern without relying on frameworks.
- ▪The Front Controller pattern centralizes request handling for web applications.
- ▪It helps eliminate duplicated code by managing common functionalities like authentication and logging in one place.
- ▪The article provides a Python implementation of the Front Controller pattern using only the standard library.
