Release Workflow

1. Pre-Release Checks

# Ensure clean working directory
git status

# Ensure on correct branch
git branch --show-current

# Pull latest changes
git pull origin main

# Run tests
npm test

# Run build
npm run build

# Check for vulnerabilities
npm audit

2. Version Bump

# Using npm (updates package.json and creates commit)
npm version patch  # 1.0.0 → 1.0.1
npm version minor  # 1.0.0 → 1.1.0
npm version major  # 1.0.0 → 2.0.0

# Pre-release versions
npm version prerelease --preid=alpha  # 1.0.0 → 1.0.1-alpha.0
npm version prerelease --preid=beta   # 1.0.0 → 1.0.1-beta.0
npm version prerelease --preid=rc     # 1.0.0 → 1.0.1-rc.0

3. Generate Changelog

# Using conventional-changelog
npx conventional-changelog -p angular -i CHANGELOG.md -s

# Or with standard-version (automates version + changelog)
npx standard-version
npx standard-version --release-as minor
npx standard-version --prerelease alpha

4. Create Tag and Push

# Tag is usually created by npm version or standard-version
# If manual:
git tag -a v1.2.0 -m "Release v1.2.0"

# Push with tags
git push origin main --follow-tags

5. Create GitHub Release

# Using GitHub CLI
gh release create v1.2.0 \
  --title "v1.2.0" \
  --notes-file RELEASE_NOTES.md

# With auto-generated notes
gh release create v1.2.0 --generate-notes

# Draft release for review
gh release create v1.2.0 --draft

6. Publish (if applicable)

# npm
npm publish

# npm with tag (for pre-releases)
npm publish --tag next
npm publish --tag beta
