Understanding Module Directives in Elixir

This article explains the four fundamental directives in Elixir for working with modules: alias, import, require, and use. Each directive has a unique purpose that helps manage code organization and maintainability. The alias directive creates shortcuts for long module names, while import allows functions to be called directly without module prefixes. The require directive is crucial for ensuring macros are compiled and available, and the use directive injects functionality from one module into another, akin to inheritance in OOP. The article also provides best practices and real-world examples to help developers use these directives effectively, avoiding common pitfalls like namespace pollution and unclear dependencies.
