GitHub Actions Certification

Continuous Integration with GitHub Actions

Project Status Meeting 1

In this article, we’ll outline our approach for creating a robust GitHub Actions workflow tailored to a Node.js application. You’ll find an overview of each phase, the reasoning behind every step, and inline comments to clarify context and intent.

Overview of Phase 1 Tasks

We’ve divided the initial work into four foundational tasks to set up our CI/CD pipeline:

Task NumberTask Description
1Analyze the Node.js application structure
2Identify dependencies and runtime requirements
3Define DevOps requirements (testing frameworks, coverage metrics)
4Prepare the repository for CI/CD integration

Note

Completing these tasks ensures we have a clear understanding of the codebase and the prerequisites for automated workflows.

Task 1: Analyze the Application Structure

  • Review the directory layout (src/, tests/, package.json, etc.).
  • Ensure all entry points and scripts are documented in package.json.

Task 2: Identify Dependencies & Runtime

  • Inspect dependencies and devDependencies in package.json.
  • Verify Node.js engine compatibility in the engines field.

Task 3: Define DevOps Requirements

  • Choose a testing framework: Jest or Mocha.
  • Set coverage thresholds (e.g., 80% line coverage).
  • Decide on linting rules (e.g., ESLint with Airbnb config).

Task 4: Prepare for CI/CD

  • Add or update README.md with build and test instructions.
  • Store environment variables and secrets in GitHub repository settings.
  • Create a skeleton .github/workflows/ci.yml file.

Warning

Never commit sensitive values (API keys, passwords) to the repo. Use GitHub Secrets for secure storage.

Upcoming Workflow Implementation

After the initial setup, we’ll implement a modular GitHub Actions workflow with dedicated jobs for:

  • Running unit tests
  • Generating code coverage reports
  • Building and publishing Docker images

Each job will be defined in its own section of the workflow file to maintain clarity and ease of maintenance.

Next Steps

  1. Conduct a code review of the Node.js application.
  2. Confirm build scripts and environment variable usage in package.json.
  3. Select and configure the testing framework.
  4. Integrate a coverage tool like Istanbul/NYC.
  5. Develop GitHub Actions jobs for:
    • Executing tests
    • Publishing coverage artifacts
    • Building & pushing Docker images

With this foundation, we’ll achieve a fully automated CI/CD pipeline that guarantees reliability and faster releases for our Node.js application.
