In this post, I’ll show how we used GitHub Actions to automate CI/CD for a real open-source fullstack application — BinaryStudioAcademy/bsa-2022-streamlet.

🧱 About the Project

The project is a collaborative platform for video content, built as part of an educational initiative. It includes:

  • Node.js backend (NestJS)
  • PostgreSQL, Prisma
  • Frontend on React
  • Docker-based development
  • Tests and linting

This made it a perfect playground to implement CI workflows.

⚙️ Why CI/CD with GitHub Actions

We wanted to:

  • Run tests on every pull request
  • Validate that code builds
  • Lint for consistency
  • Eventually — deploy to environments

And we didn’t want to add extra tools or services — just GitHub.

🚀 Creating the GitHub Actions Workflow

All CI/CD workflows live in .github/workflows/. Here’s a minimal setup for Node.js:

name: CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v3
    - name: Use Node.js
      uses: actions/setup-node@v3
      with:
        node-version: 18

    - run: npm install
    - run: npm run lint
    - run: npm run test

✅ Tip: You can create multiple workflows for frontend/backend separately if needed.

🧪 Test Output in GitHub UI

After pushing a PR, GitHub shows CI status directly in the PR tab. Green means ✅ everything is passing.

You can also explore logs in the Actions tab. This helps reviewers catch problems early — before merging anything into main.

📦 Expanding to Deployments

In advanced scenarios, we also:

  • Built Docker images
  • Deployed to staging (with secrets)
  • Used concurrency to cancel stale builds

But even with just the basics, we improved code quality and confidence.

⚠️ Gotchas & Lessons Learned

  • Always cache node_modules to speed up runs (with actions/cache)
  • Keep workflows fast — slow pipelines discourage devs
  • If you split into microservices — build and test them in parallel
  • Protect main branch using CI rules in GitHub settings

✅ Conclusion

GitHub Actions is a powerful and free way to bring CI/CD into any project — even student or hobby apps. Our team benefited a lot from having automated checks, and it made collaboration smooth and scalable.

If you're just starting, don’t overcomplicate. Start with one workflow file. Add jobs as your project grows.
