Automating your development workflow can save time, reduce errors, and streamline your processes. GitHub Actions is a powerful CI/CD platform that allows you to automate tasks like testing, building, and deploying your code directly within your GitHub repository. Whether you’re a beginner or looking to deepen your understanding, this guide will walk you through creating both simple workflow-based actions and custom GitHub Actions.

Understanding GitHub Actions

GitHub Actions is a feature of GitHub that enables you to automate tasks within your software development lifecycle. Actions are defined in YAML files located in the .github/workflows/ directory of your repository. These workflows can be triggered by various events such as pushes, pull requests, or on a schedule.

Key Concepts

• Workflow: An automated process set up in your repository.
• Event: A specific activity that triggers a workflow (e.g., push, pull request).
• Job: A set of steps executed on the same runner.
• Step: An individual task within a job.
• Action: A reusable unit of code that can be combined to create a workflow.

Creating a Simple Workflow-Based GitHub Action

Let’s start by creating a basic workflow that runs tests whenever you push code to the main branch.

Step 1: Create the Workflow File

1. Navigate to Your Repository: Go to the repository where you want to add the GitHub Action.
2. Create Workflow Directory: Inside your repository, create a directory named .github/workflows.
3. Add a Workflow File: Inside the workflows directory, create a file named ci.yml (you can name it anything).

Step 2: Define the Workflow

Open ci.yml and add the following content:

name: CI

on:
  push…
