If you’ve ever wanted to automate tasks in your GitHub repository like running tests, building code, or deploying an app. GitHub Actions is the tool for the job. It lets you create workflows that run automatically when certain events happen in your repo.

What is GitHub Actions?

GitHub Actions is a feature that allows you to define automation directly in your repository. You can use it to:

  • Run tests whenever someone pushes code.
  • Build and package applications automatically.
  • Deploy projects to servers or cloud providers.

What is a Workflow?

A workflow is simply a set of instructions written in YAML that tells GitHub what to do. Workflows live in a folder called .github/workflows/ in your repository.

Here’s a super basic example:

name: CI Workflow

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v3
      
      - name: Run a simple script
        run: echo "Hello, GitHub Actions!"

Breaking it down:

  • name: The name of the workflow.
  • on: Defines when the workflow runs. In this case, every time code is pushed.
  • jobs: A workflow can have one or more jobs.
  • steps: The individual tasks inside a job, like checking out code or running a script.

Why Use GitHub Actions?

  • Automation: Saves time by running repetitive tasks for you.
  • Integration: Works seamlessly with GitHub.
  • Flexibility: Supports many programming languages and tools.

✅ That’s it! With just a few lines of YAML, you’ve automated part of your development process. As you get more comfortable, you can add tests, builds, and deployments to your workflows.
