Workflow
Step 1: Analyze Changes
# View staged changes
git diff --cached --stat
git diff --cached
Step 2: Determine Type
- Adding new functionality? →
feat - Fixing a bug? →
fix - Updating docs? →
docs - Refactoring without behavior change? →
refactor
Step 3: Write Subject
✅ GOOD: feat(api): add user authentication endpoint
❌ BAD: updated stuff
❌ BAD: feat: Add User Authentication Endpoint (no caps after colon)
Rules:
- Imperative mood ("add" not "added")
- No period at end
- Max 50 characters
- Lowercase after colon
Step 4: Write Body (optional)
feat(auth): add OAuth2.0 authentication
Implement OAuth2.0 flow with Google and GitHub providers.
This replaces the legacy session-based auth system.
- Add OAuth callback handlers
- Store refresh tokens securely
- Add logout functionality
Step 5: Add Footer (optional)
BREAKING CHANGE: auth tokens now expire after 24h
Closes #123
