  • Security incident review
  • Dependency update impact
  • Documentation usage metrics

🚨 Issue Response Procedures

Critical Issues (P0)

Response Time: Immediate (< 1 hour)

  • Security vulnerabilities
  • Production outages
  • Data loss incidents

Actions:

  1. Immediate assessment and containment
  2. Emergency fix deployment
  3. Post-incident review and documentation
  4. Process improvement implementation

High Priority Issues (P1)

Response Time: Same day (< 8 hours)

  • Performance degradation
  • Feature failures
  • Build pipeline failures

Actions:

  1. Investigation and root cause analysis
  2. Fix development and testing
  3. Coordinated deployment
  4. Monitoring and verification

Medium Priority Issues (P2)

Response Time: Within 3 days

  • Minor bugs
  • Documentation issues
  • Enhancement requests

Actions:

  1. Triage and prioritization
  2. Development planning
  3. Implementation in next release cycle
  4. Testing and validation

Low Priority Issues (P3)

Response Time: Next release cycle

  • Nice-to-have features
  • Minor improvements
  • Technical debt

🔄 Release Management

Version Numbering

Following Semantic Versioning:

  • MAJOR: Breaking changes
  • MINOR: New features (backward compatible)
  • PATCH: Bug fixes (backward compatible)

Release Process

  1. Preparation

    # Update version in package.json
npm version [major|minor|patch]

# Update CHANGELOG.md
# Review and test changes
npm run build

  2. Release

    # Create and push tag
git push origin main --tags

# GitHub Actions will handle the rest:
# - Create GitHub release
# - Build Docker image
# - Generate release notes

  3. Post-Release

    • Monitor deployment
    • Verify functionality
    • Update documentation
    • Communicate changes

Hotfix Process

For critical production issues:

  1. Create hotfix branch from main

    git checkout main
git checkout -b hotfix/critical-fix

  2. Implement and test fix

    # Make minimal changes
# Run tests
npm test

  3. Deploy hotfix

    # Merge to main
git checkout main
git merge hotfix/critical-fix

# Create patch version
npm version patch
git push origin main --tags
