**Course Title:** Build and Package Management in Modern Development **Section Title:** Continuous Integration and Deployment (CI/CD) **Topic:** Set up a simple CI pipeline using GitHub Actions for a Node.js project.(Lab topic) **Objective:** By the end of this lab, you will be able to set up a simple CI pipeline using GitHub Actions for a Node.js project, automate the build and test process, and ensure seamless integration of changes into your application. **Introduction to GitHub Actions** --------------------------- GitHub Actions is a continuous integration and continuous deployment (CI/CD) tool that allows you to automate your build, test, and deployment pipeline. It is directly integrated into your GitHub workflow, enabling you to create workflows that trigger on different events such as push, pull request, and issue creation. **Prerequisites** ---------------- * A GitHub account with a repository for your Node.js project * A basic understanding of Node.js and GitHub * A computer with Node.js installed **Step 1: Create a New GitHub Actions Workflow** ------------------------------------------ 1. Log in to your GitHub account and navigate to your repository. 2. Click on the "Actions" tab in the top navigation bar. 3. Click on the "New workflow" button. 4. Choose the "Node.js" template. 5. Name your workflow (e.g., "Node.js CI"). **Step 2: Configure Your Workflow** --------------------------------- In the workflow file (`nodejs.yml`), you'll need to configure the following: ### `name` and `on` * The `name` field specifies the name of your workflow. * The `on` field specifies the event that triggers the workflow. For this lab, we'll use the `push` event. ```yml name: Node.js CI on: push: branches: [ main ] ``` ### `jobs` * The `jobs` field defines the build and test process. We'll create a single job called "build-and-test". ```yml jobs: build-and-test: runs-on: ubuntu-latest ``` * The `runs-on` field specifies the environment in which the job runs. ### `steps` * The `steps` field defines the sequence of tasks that make up the job. We'll have two steps: "Checkout code" and "Install and test". ```yml steps: - name: Checkout code uses: actions/checkout@v2 - name: Install and test run: | npm install npm run test ``` **Step 3: Save and Trigger the Workflow** --------------------------------------- 1. Save the workflow file. 2. Commit the changes to your repository. The workflow will automatically trigger on the `push` event. **Step 4: Verify the Workflow** ------------------------------ 1. Go back to the "Actions" tab in your repository. 2. Click on the workflow run that was triggered. 3. Verify that the workflow completed successfully. **Conclusion** -------------- You have now set up a simple CI pipeline using GitHub Actions for your Node.js project. This pipeline automates the build and test process, ensuring seamless integration of changes into your application. **Key Takeaways** * Create a new GitHub Actions workflow for your Node.js project. * Configure the workflow to trigger on the `push` event. * Define a job that runs on the `ubuntu-latest` environment. * Define steps that checkout the code, install dependencies, and run tests. **What's Next?** ----------------- In the next topic, we'll explore containerization with Docker and learn how to package our application for deployment. **External Links:** * [GitHub Actions Documentation](https://docs.github.com/en/actions) * [GitHub Actions Workflow Syntax](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions) **Comments and Questions?** --------------------------- Feel free to ask questions or share your thoughts on this topic.
