Mixing It Up: Creating Custom Mix Tasks in Elixir

Mix tasks are a powerful tool in the Elixir ecosystem, allowing you to automate various development tasks. Let's explore how to create custom Mix tasks to enhance your Elixir projects.

Introduction

Mix tasks are commands that can be run in the terminal to perform various tasks related to your Elixir project. While Mix comes with many built-in tasks, you can also create custom tasks to suit your specific needs.

Creating a Custom Mix Task

Let's create a simple Mix task that greets the user:

# lib/mix/tasks/greet.ex
defmodule Mix.Tasks.Greet do
  use Mix.Task
 
  def run(_) do
    IO.puts("Hello, Elixir Developer!")
  end
end

After creating the file, you can run your custom Mix task using:

mix greet

Creating custom Mix tasks allows you to extend your project's functionality in a clean and modular way.
