Elixir Modules

Using Elixir Modules

Elixir modules use defmodule for code organization and reuse.

Introduction to Elixir Modules

Elixir modules are a fundamental aspect of the language, providing a way to organize and encapsulate code. They are defined using the defmodule keyword, which allows developers to group related functions and data together.

Defining a Module

To define a module in Elixir, use the defmodule keyword followed by the module name. Inside the module, you can define functions using the def keyword.

Using a Module

Once a module is defined, you can use its functions by calling them with the module name followed by a dot and the function name:

Module Attributes

Modules can also have attributes, which are stored as key-value pairs. These attributes can be used to store metadata or constants.

Nested Modules

Elixir supports nesting modules within other modules, which is useful for organizing code hierarchically. Nesting is done by simply defining a module inside another module.

Conclusion

Elixir modules are powerful tools for organizing code and promoting reuse. By using defmodule, you can create well-structured, maintainable applications. In the next post, we will explore Mix, Elixir's build tool.
