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 Number | Task Description |
---|---|
1 | Analyze the Node.js application structure |
2 | Identify dependencies and runtime requirements |
3 | Define DevOps requirements (testing frameworks, coverage metrics) |
4 | Prepare 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
anddevDependencies
inpackage.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
- Conduct a code review of the Node.js application.
- Confirm build scripts and environment variable usage in
package.json
. - Select and configure the testing framework.
- Integrate a coverage tool like Istanbul/NYC.
- 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.
