# Git Commands Reference

This document provides essential Git commands for developing the Enterprise Asset Management System.

## Basic Development Workflow

### 1. **Check Status & See Changes**
```bash
git status                    # See what files are modified
git diff                      # See specific changes in files
git diff --staged             # See staged changes
```

### 2. **Stage & Commit Changes**
```bash
# Stage specific files
git add filename.js
git add frontend/src/views/

# Stage all changes
git add .

# Commit with message
git commit -m "Add user authentication feature"
```

### 3. **Push to Remote**
```bash
git push                      # Push current branch to remote
git push origin main          # Push main branch explicitly
```

## Feature Development Workflow

### **Option A: Simple (Direct to main)**
```bash
# Make changes, then:
git add .
git commit -m "Implement asset filtering feature"
git push
```

### **Option B: Feature Branches (Recommended)**
```bash
# Create and switch to feature branch
git checkout -b feature/asset-export

# Make changes, then:
git add .
git commit -m "Add CSV export functionality"
git push -u origin feature/asset-export

# When ready to merge:
git checkout main
git merge feature/asset-export
git push
git branch -d feature/asset-export  # Delete local branch
```

## Quick Reference Commands

### **Daily Commands**
```bash
git pull                      # Get latest changes from remote
git add .                     # Stage all changes
git commit -m "Your message"  # Commit with message
git push                      # Push to remote
```

### **Useful Checks**
```bash
git log --oneline -10         # See last 10 commits
git branch -a                 # See all branches
git remote -v                 # Check remote URLs
```

### **Undo Commands**
```bash
git reset HEAD~1              # Undo last commit (keep changes)
git checkout -- filename.js  # Discard changes to file
git restore filename.js       # Discard changes (newer syntax)
```

## Recommended Commit Message Format

```bash
git commit -m "Add asset search functionality

- Implement real-time search in Assets.vue
- Add debounced search input
- Update AssetRepository with search filters
- Add search tests"
```

## Advanced Commands

### **Branch Management**
```bash
git branch                    # List local branches
git branch -r                 # List remote branches
git branch -a                 # List all branches
git branch -d branch-name     # Delete local branch
git push origin --delete branch-name  # Delete remote branch
```

### **Stashing Changes**
```bash
git stash                     # Save changes temporarily
git stash pop                 # Restore stashed changes
git stash list                # List all stashes
git stash drop                # Delete latest stash
```

### **Remote Management**
```bash
git remote add origin <url>   # Add remote repository
git remote -v                 # Show remote URLs
git remote set-url origin <new-url>  # Change remote URL
```

### **Syncing with Remote**
```bash
git fetch                     # Download remote changes (don't merge)
git pull                      # Download and merge remote changes
git pull --rebase             # Pull with rebase instead of merge
```

## Common Scenarios

### **Starting a New Feature**
```bash
git checkout main
git pull
git checkout -b feature/new-feature
# Make changes
git add .
git commit -m "Implement new feature"
git push -u origin feature/new-feature
```

### **Updating Your Branch with Latest Main**
```bash
git checkout main
git pull
git checkout feature/your-feature
git merge main
# Or use rebase for cleaner history:
git rebase main
```

### **Quick Fix Workflow**
```bash
git checkout main
git pull
git checkout -b hotfix/fix-critical-bug
# Make fix
git add .
git commit -m "Fix critical bug in authentication"
git push -u origin hotfix/fix-critical-bug
# Create pull request or merge directly
```

## Best Practices

1. **Always pull before starting work:**
   ```bash
   git pull
   ```

2. **Use descriptive commit messages:**
   ```bash
   git commit -m "Fix asset deletion not updating UI cache"
   ```

3. **Stage changes selectively:**
   ```bash
   git add -p  # Interactive staging
   ```

4. **Check what you're committing:**
   ```bash
   git diff --staged
   ```

5. **Use feature branches for new features:**
   ```bash
   git checkout -b feature/asset-export
   ```

## Emergency Commands

### **Undo Last Commit (but keep changes)**
```bash
git reset --soft HEAD~1
```

### **Completely Discard All Changes**
```bash
git reset --hard HEAD
```

### **Go Back to Previous Commit**
```bash
git log --oneline  # Find commit hash
git reset --hard <commit-hash>
```

### **Create Branch from Specific Commit**
```bash
git checkout -b new-branch <commit-hash>
```

## Project-Specific Notes

- **Main branch:** `main`
- **Remote name:** `origin`
- **Typical feature branch naming:** `feature/description` or `fix/description`
- **For this project:** Always test locally before pushing to ensure the app builds and runs correctly

## Pro Tips

- Use `git add -p` to selectively stage parts of files
- Use `git log --graph --oneline --all` for visual commit history
- Set up aliases for common commands in `~/.gitconfig`
- Use `git blame filename` to see who changed each line
- Use `git show <commit-hash>` to see details of a specific commit

---

**Remember:** Always ensure your code works locally before committing and pushing to avoid breaking the remote repository!
