# Git Workflow

Git best practices, commit conventions, branching strategies, and pull request workflows. Guidelines for maintaining a clean, useful git history.

## When to Apply

Reference these guidelines when:
- Writing commit messages
- Creating branches
- Setting up git workflows
- Reviewing pull requests
- Maintaining git history

## Rule Categories by Priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Commit Messages | CRITICAL | `commit-` |
| 2 | Branching Strategy | HIGH | `branch-` |
| 3 | Pull Requests | HIGH | `pr-` |
| 4 | History Management | MEDIUM | `history-` |
| 5 | Collaboration | MEDIUM | `collab-` |

## Quick Reference

### 1. Commit Messages (CRITICAL)

- `commit-conventional` - Use conventional commits
- `commit-atomic` - Atomic commits (one logical change)
- `commit-present-tense` - Use imperative present tense
- `commit-meaningful` - Descriptive, meaningful messages
- `commit-body` - Add body for complex changes
- `commit-references` - Reference issues/tickets
- `commit-git-hooks` - Enforce standards with Husky + commitlint

### 2. Branching Strategy (HIGH)

- `branch-naming` - Consistent branch naming
- `branch-feature` - Feature branch workflow
- `branch-main-protected` - Protect main branch
- `branch-short-lived` - Keep branches short-lived
- `branch-delete-merged` - Delete merged branches
- `branch-release` - Release branch strategy
- `branch-workflow-strategies` - GitFlow vs GitHub Flow vs Trunk-Based
- `branch-monorepo` - Monorepo git workflows

### 3. Pull Requests (HIGH)

- `pr-small` - Keep PRs small and focused
- `pr-description` - Write clear descriptions
- `pr-reviewers` - Request appropriate reviewers
- `pr-ci-pass` - Ensure CI passes
- `pr-squash` - Squash when appropriate
- `pr-draft` - Use draft PRs for WIP and early feedback

### 4. History Management (MEDIUM)

- `history-rebase` - Rebase vs merge
- `history-no-force-push` - Avoid force push to shared branches
- `history-clean` - Keep history clean
- `history-tags` - Use tags for releases
- `history-worktree` - Work on multiple branches with git worktree

### 5. Collaboration (MEDIUM)

- `collab-code-review` - Effective code reviews
- `collab-conflicts` - Handle merge conflicts
- `collab-communication` - Communicate changes
- `collab-gitignore` - .gitignore best practices

## Essential Guidelines

### Conventional Commits

```
# Format
<type>(<scope>): <subject>

<body>

<footer>
```

#### Types

| Type | Description |
|------|-------------|
| `feat` | New feature |
| `fix` | Bug fix |
| `docs` | Documentation only |
| `style` | Formatting, no code change |
| `refactor` | Code change, no feature/fix |
| `perf` | Performance improvement |
| `test` | Adding/updating tests |
| `chore` | Maintenance, dependencies |
| `ci` | CI/CD changes |
| `build` | Build system changes |
| `revert` | Revert previous commit |

#### Examples

```bash
# ✅ Good commit messages
feat(auth): add password reset functionality

fix(cart): resolve quantity update race condition

docs(readme): add installation instructions

refactor(api): extract validation into middleware

test(user): add unit tests for registration

chore(deps): update dependencies to latest versions

# With body and footer
feat(orders): implement order cancellation

Add ability for users to cancel pending orders within 24 hours.
Cancelled orders trigger refund process automatically.

Closes #123
BREAKING CHANGE: Order status enum now includes 'cancelled'

# ❌ Bad commit messages
fix bug
update
WIP
asdfasdf
changes
misc fixes
```

### Branch Naming

```bash
# ✅ Good branch names
feature/user-authentication
feature/JIRA-123-password-reset
fix/cart-total-calculation
fix/issue-456-login-redirect
hotfix/security-patch
docs/api-documentation
refactor/database-queries
chore/update-dependencies

# ❌ Bad branch names
new-feature
john-branch
test
fix
temp
asdf
```

### Branch Workflow

```bash
# Main branches
main          # Production-ready code
develop       # Integration branch (optional)

# Supporting branches
feature/*     # New features
fix/*         # Bug fixes
hotfix/*      # Production hotfixes
release/*     # Release preparation

# Workflow
git checkout main
git pull origin main
git checkout -b feature/user-profile

# Work on feature...
git add .
git commit -m "feat(profile): add profile page"

# Keep branch updated
git fetch origin
git rebase origin/main

# Push and create PR
git push -u origin feature/user-profile
```

### Atomic Commits

```bash
# ❌ One commit doing multiple things
git commit -m "Add login, fix header, update deps"

# ✅ Separate commits for each change
git commit -m "feat(auth): add login page"
git commit -m "fix(header): correct navigation alignment"
git commit -m "chore(deps): update React to v18.2"
```

### Commit Frequently, Push Regularly

```bash
# ✅ Small, frequent commits
git commit -m "feat(cart): add product to cart"
git commit -m "feat(cart): display cart item count"
git commit -m "feat(cart): implement remove item"
git commit -m "test(cart): add unit tests"

# ❌ One massive commit
git commit -m "feat: implement entire shopping cart"
```

### Pull Request Best Practices

#### PR Title

```
# Format (like commit)
<type>(<scope>): <description>

# ✅ Good PR titles
feat(auth): implement OAuth2 login
fix(checkout): resolve payment processing error
docs(api): add endpoint documentation

# ❌ Bad PR titles
Update
Fix stuff
WIP
```

### Keep PRs Small

```
# ✅ Focused PRs
PR #1: Add user model and migrations
PR #2: Implement user registration endpoint
PR #3: Add email verification
PR #4: Implement login/logout

# ❌ Large unfocused PR
PR #1: Add entire user authentication system
       (2000+ lines, 50+ files)
```

### Rebase vs Merge

```bash
# ✅ Rebase for feature branches (clean history)
git checkout feature/my-feature
git fetch origin
git rebase origin/main
# Resolve any conflicts
git push --force-with-lease  # Only your branch!

# ✅ Merge for integrating to main (preserve context)
git checkout main
git merge --no-ff feature/my-feature
# Creates merge commit, preserves branch history

# ❌ Never force push to shared branches
git push --force origin main  # NEVER DO THIS
```

### Interactive Rebase (Clean Up)

```bash
# Before pushing, clean up commits
git rebase -i HEAD~5

# In editor:
pick abc123 feat: add login page
squash def456 fix typo
squash ghi789 more fixes
pick jkl012 feat: add logout

# Result: clean history with meaningful commits
```

### Handling Conflicts

```bash
# During rebase
git rebase origin/main
# CONFLICT in file.ts

# 1. Open conflicted files
# 2. Resolve conflicts (remove markers)
# 3. Stage resolved files
git add file.ts

# 4. Continue rebase
git rebase --continue

# Or abort if needed
git rebase --abort
```

### Git Hooks

```bash
# .husky/pre-commit
#!/bin/sh
npm run lint
npm run test:unit

# .husky/commit-msg
#!/bin/sh
npx commitlint --edit $1

# commitlint.config.js
module.exports = {
  extends: ['@commitlint/config-conventional'],
};
```

### Tagging Releases

```bash
# Semantic versioning tags
git tag -a v1.0.0 -m "Release version 1.0.0"
git push origin v1.0.0

# List tags
git tag -l "v1.*"

# Tag format
v1.0.0    # Major.Minor.Patch
v1.0.0-beta.1  # Pre-release
v1.0.0-rc.1    # Release candidate
```

### .gitignore Best Practices

```gitignore
# Dependencies
node_modules/
vendor/

# Build outputs
dist/
build/
.next/

# Environment files
.env
.env.local
.env.*.local

# IDE
.idea/
.vscode/
*.swp

# OS files
.DS_Store
Thumbs.db

# Logs
*.log
logs/

# Test coverage
coverage/

# Cache
.cache/
*.cache
```

### Useful Git Commands

```bash
# View commit history
git log --oneline --graph --all

# See what changed
git diff --staged
git diff HEAD~1

# Undo last commit (keep changes)
git reset --soft HEAD~1

# Discard local changes
git checkout -- file.ts
git restore file.ts  # Git 2.23+

# Stash changes
git stash
git stash pop
git stash list

# Cherry-pick commit
git cherry-pick abc123

# Find who changed a line
git blame file.ts

# Search commits
git log --grep="fix"
git log -S "functionName"
```

## Output Format

When reviewing git practices, output findings:

```
[category] Description of issue or suggestion
```

Example:
```
[commit] Use imperative mood: "Add feature" not "Added feature"
[branch] Branch name 'test' should follow pattern: feature/description
[pr] PR is too large (50+ files), consider splitting
```

## How to Use
