Release Process

1. Prepare Release

# Create release branch (if using git-flow)
git checkout -b release/v1.2.3 develop

# Update version (using npm via bunx for version bumping)
bunx npm version patch|minor|major

# Update CHANGELOG
# Add release notes

2. Final Verification

# Run all checks
bun run lint:fix
bun run build
bun run test

# Verify in staging
# - Core user flows
# - New features
# - Known edge cases

3. Deploy

# Tag the release
git tag -a v1.2.3 -m "Release v1.2.3"

# Push to trigger deployment
git push origin v1.2.3

# Or manual deployment
# [project-specific deployment command]

4. Post-Deploy Verification

Immediately after deployment:

• Health checks pass
• Application loads
• Core flows work (login, main features)
• No error spikes in monitoring
• Performance metrics normal

Monitor for 30 minutes:

• Error rates stable
• Response times normal
• No memory leaks
• Database performance stable

5. Communicate

• Update status page
• Notify stakeholders
• Close related tickets
• Update project board

Rollback Procedure

When to Rollback

• Critical functionality broken
• Error rate exceeds threshold
• Performance severely degraded
• Security vulnerability discovered

Rollback Steps

1. Decide: Hotfix or rollback?

   • Hotfix: Issue is small, fix is obvious
   • Rollback: Issue is complex or unknown

2. Execute Rollback

# Revert to previous version
# [project-specific rollback command]

# Or redeploy previous tag
git checkout v1.2.2
# [deploy]

3. Database Rollback (if needed)

# Run rollback migration
# [project-specific command]

4. Verify

• Previous version running
• Core functionality restored
• Error rates normalized

5. Communicate

• Update status page
• Notify stakeholders
• Create incident ticket
