Code Review Workflow

This repository uses automated code review via GitHub Actions to ensure code quality, security, and build integrity.

Workflow Overview

The code review workflow (code-review.yml) automatically runs when:

  • A pull request is opened or updated targeting the main branch
  • Code is pushed directly to the main branch

Review Stages

1. Code Quality & Build Check

This stage validates the code quality and ensures the application builds successfully:

Client (Frontend)

  • Dependency Installation: Installs all client dependencies using npm ci
  • Prettier Format Check: Validates code formatting against Prettier rules
  • Build Verification: Ensures the React application builds without errors
  • Test Execution: Runs all client-side tests (if available)

Server (Backend)

  • Dependency Installation: Installs all server dependencies using npm ci
  • Syntax Validation: Checks for JavaScript syntax errors
  • Dependency Audit: Validates package.json dependencies

2. Security Scan

This stage identifies potential security vulnerabilities:

  • CodeQL Analysis: Performs advanced security and quality analysis on JavaScript code
  • Dependency Audit (Client): Scans client dependencies for known vulnerabilities
  • Dependency Audit (Server): Scans server dependencies for known vulnerabilities

3. Docker Build Verification

This stage ensures Docker images can be built successfully:

  • Client Docker Build: Validates the client Dockerfile
  • Server Docker Build: Validates the server Dockerfile
  • Docker Compose Check: Verifies docker-compose.yaml configuration

4. Review Summary

Provides an overall summary of all checks and reports the final status.

Status Badges

You can add the following badge to your README.md to show the workflow status:

Important Notes

Soft Failures

Some checks are currently set to continue-on-error: true, which means they report issues but don't block the workflow:

  • Prettier formatting check: Allows formatting violations (remove flag once codebase is fully formatted)
  • Client tests: Allows test failures (remove flag once all tests pass consistently)
  • Package validation: Allows dependency warnings (remove flag once dependencies are resolved)
  • npm audit: Allows security vulnerabilities (remove flag once critical issues are resolved)

These flags are in place to avoid blocking the workflow on pre-existing issues. As you improve the codebase:

  1. Fix the underlying issues (formatting, tests, dependencies, vulnerabilities)
  2. Remove the corresponding continue-on-error: true flag from .github/workflows/code-review.yml
  3. Enforce strict checks for new code

Troubleshooting

Failed Prettier Check

If the Prettier check fails, run the following to format your code:

cd client
npx prettier --write "src/**/*.{js,jsx,ts,tsx,json,css,scss,md}"

Failed Build

If the build fails, check the error logs in the GitHub Actions tab. Common issues include:

  • Missing environment variables
  • Dependency conflicts
  • Syntax errors

Failed Security Scan

If security vulnerabilities are detected:

  1. Review the CodeQL alerts in the Security tab
  2. Run npm audit fix in the affected directory (client or server)
  3. Update vulnerable dependencies

Failed Docker Build

If Docker builds fail:

  1. Test locally with docker build -t test ./client or docker build -t test ./server
  2. Ensure all required files are present and not in .dockerignore
  3. Check Dockerfile syntax and paths

Local Testing

Before pushing code, you can run these checks locally:

# Client checks
cd client
npm ci
npx prettier --check "src/**/*.{js,jsx,ts,tsx,json,css,scss,md}"
npm run build
npm test

# Server checks
cd server
npm ci
node -c index.js
npm audit

# Docker checks
docker build -t edtech-client:test ./client
docker build -t edtech-server:test ./server
docker-compose config

Configuration

The workflow uses:

  • Node.js version: 18.x
  • Runner: ubuntu-latest
  • Permissions: Read access to code, write access for security events

Continuous Integration

This workflow is part of the CI/CD pipeline mentioned in the README. It ensures that:

  • All code changes are reviewed automatically
  • Security vulnerabilities are caught early
  • Build integrity is maintained
  • Code quality standards are enforced

Future Enhancements

Potential improvements to the code review workflow:

  • Add ESLint configuration and checks
  • Implement code coverage reporting
  • Add performance testing
  • Integrate automated PR comments with review results
  • Add deployment preview for approved PRs
