Understanding composite actions

Composite actions are reusable and customizable units of functionality in GitHub Actions. They allow you to encapsulate a sequence of steps into a single action, which can be easily reused across multiple workflows and repositories. Composite actions are created using YAML files, providing a flexible and modular approach to building complex workflows. Let’s start with understanding some of the fundamental concepts involved.

Key concepts of composite actions

Composite actions in GitHub Actions are built on several key concepts that make them a powerful tool for encapsulating and reusing functionality across workflows and repositories. These concepts form the foundation for creating modular and customizable actions that promote code reuse, maintainability, and consistency. Let’s look at some of them in detail:

• Encapsulation: Composite actions encapsulate a sequence of steps into a single reusable unit. This allows you to abstract...
