# Create Worktrees Command
|
|
|
|
Set up Git worktrees to work on multiple branches simultaneously without switching contexts.
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
/create-worktrees <branch_name> [base_branch] [path]
|
|
```
|
|
|
|
**Examples:**
|
|
```bash
|
|
/create-worktrees feature/new-auth # Create worktree for new branch
|
|
/create-worktrees hotfix/security-patch main # Create from main branch
|
|
/create-worktrees feature/api-v2 develop ../worktrees/api-v2 # Custom path
|
|
```
|
|
|
|
## What This Command Does
|
|
|
|
Creates Git worktrees that allow you to:
|
|
|
|
1. **Work on Multiple Branches**: Switch between features without stashing
|
|
2. **Parallel Development**: Build/test different branches simultaneously
|
|
3. **PR Reviews**: Check out PRs without affecting main work
|
|
4. **Hotfix Management**: Work on urgent fixes while continuing feature work
|
|
5. **Efficient Testing**: Compare changes across branches easily
|
|
|
|
## Git Worktrees Explained
|
|
|
|
A worktree is a linked working directory that shares the same Git repository:
|
|
|
|
```
|
|
project/
|
|
├── .git/ # Main repository
|
|
├── src/ # Main branch
|
|
└── ../worktrees/
|
|
├── feature-a/ # Worktree for feature-a branch
|
|
├── feature-b/ # Worktree for feature-b branch
|
|
└── pr-123/ # Worktree for PR review
|
|
```
|
|
|
|
**Benefits**:
|
|
- No need to stash changes when switching branches
|
|
- Run tests on multiple branches simultaneously
|
|
- Keep builds for different branches ready
|
|
- Review PRs without disrupting current work
|
|
|
|
## Creating Worktrees
|
|
|
|
### Basic Worktree Creation
|
|
|
|
```bash
|
|
# Create worktree for new branch
|
|
git worktree add ../worktrees/feature-xyz -b feature/xyz
|
|
|
|
# Create from existing branch
|
|
git worktree add ../worktrees/hotfix origin/hotfix/security
|
|
|
|
# Create from specific commit
|
|
git worktree add ../worktrees/test-v1 abc123
|
|
```
|
|
|
|
### Recommended Workflow
|
|
|
|
**Step 1: Create Worktree**
|
|
```bash
|
|
# Create worktree directory structure
|
|
mkdir -p ../worktrees
|
|
|
|
# Add worktree for new feature
|
|
git worktree add ../worktrees/feature-auth -b feature/user-auth
|
|
|
|
# Navigate to worktree
|
|
cd ../worktrees/feature-auth
|
|
```
|
|
|
|
**Step 2: Work in Worktree**
|
|
```bash
|
|
# Make changes
|
|
vim src/auth/login.js
|
|
|
|
# Commit normally
|
|
git add .
|
|
git commit -m "Add user authentication"
|
|
git push -u origin feature/user-auth
|
|
```
|
|
|
|
**Step 3: List Worktrees**
|
|
```bash
|
|
git worktree list
|
|
# Output:
|
|
# /path/to/project abc123 [main]
|
|
# /path/to/worktrees/feature-auth def456 [feature/user-auth]
|
|
```
|
|
|
|
## Common Use Cases
|
|
|
|
### 1. PR Review Workflow
|
|
|
|
Review pull requests without affecting your current work:
|
|
|
|
```bash
|
|
# Fetch PR branch
|
|
gh pr checkout 123
|
|
|
|
# Or manually
|
|
git fetch origin pull/123/head:pr-123
|
|
git worktree add ../worktrees/pr-123 pr-123
|
|
|
|
# Review the code
|
|
cd ../worktrees/pr-123
|
|
npm install
|
|
npm test
|
|
npm run build
|
|
|
|
# Return to your work
|
|
cd ../../project
|
|
```
|
|
|
|
### 2. Multi-Feature Development
|
|
|
|
Work on multiple features simultaneously:
|
|
|
|
```bash
|
|
# Feature A
|
|
git worktree add ../worktrees/feature-a -b feature/payment-gateway
|
|
cd ../worktrees/feature-a
|
|
npm install
|
|
npm run dev # Runs on port 3000
|
|
|
|
# Feature B (in another terminal)
|
|
cd /path/to/project
|
|
git worktree add ../worktrees/feature-b -b feature/notification-system
|
|
cd ../worktrees/feature-b
|
|
npm install
|
|
PORT=3001 npm run dev # Runs on port 3001
|
|
```
|
|
|
|
### 3. Hotfix While Developing
|
|
|
|
Handle urgent fixes without stashing feature work:
|
|
|
|
```bash
|
|
# You're working on a feature
|
|
cd /path/to/worktrees/feature-dashboard
|
|
|
|
# Urgent hotfix needed
|
|
cd /path/to/project
|
|
git worktree add ../worktrees/hotfix-urgent -b hotfix/security-patch main
|
|
cd ../worktrees/hotfix-urgent
|
|
|
|
# Fix the issue
|
|
vim src/security/validator.js
|
|
git add .
|
|
git commit -m "Fix security vulnerability"
|
|
git push -u origin hotfix/security-patch
|
|
|
|
# Create PR for hotfix
|
|
gh pr create --title "Security patch" --base main
|
|
|
|
# Return to feature work
|
|
cd ../feature-dashboard
|
|
```
|
|
|
|
### 4. Testing Across Branches
|
|
|
|
Compare behavior across different branches:
|
|
|
|
```bash
|
|
# Main branch
|
|
cd /path/to/project
|
|
npm test
|
|
|
|
# Feature branch
|
|
cd ../worktrees/feature-new-api
|
|
npm test
|
|
|
|
# Compare results side by side
|
|
```
|
|
|
|
## Managing Worktrees
|
|
|
|
### List Worktrees
|
|
|
|
```bash
|
|
# List all worktrees
|
|
git worktree list
|
|
|
|
# Detailed view
|
|
git worktree list --porcelain
|
|
```
|
|
|
|
### Remove Worktrees
|
|
|
|
```bash
|
|
# Remove worktree (safe - checks for uncommitted changes)
|
|
git worktree remove ../worktrees/feature-completed
|
|
|
|
# Force remove (use with caution)
|
|
git worktree remove --force ../worktrees/abandoned-feature
|
|
|
|
# Or manually delete and prune
|
|
rm -rf ../worktrees/old-feature
|
|
git worktree prune
|
|
```
|
|
|
|
### Clean Up Stale Worktrees
|
|
|
|
```bash
|
|
# Show stale worktrees
|
|
git worktree prune --dry-run
|
|
|
|
# Remove stale references
|
|
git worktree prune
|
|
```
|
|
|
|
## Advanced Techniques
|
|
|
|
### Batch Create Worktrees for PRs
|
|
|
|
```bash
|
|
# Create worktrees for multiple PRs
|
|
gh pr list --json number,headRefName --limit 5 | \
|
|
jq -r '.[] | "\(.number) \(.headRefName)"' | \
|
|
while read -r pr_num branch; do
|
|
git worktree add "../worktrees/pr-$pr_num" "$branch" 2>/dev/null || \
|
|
git worktree add "../worktrees/pr-$pr_num" -b "$branch" "origin/$branch"
|
|
done
|
|
```
|
|
|
|
### Worktree with Environment Setup
|
|
|
|
```bash
|
|
# Create worktree with automatic setup
|
|
create_worktree_with_setup() {
|
|
local branch=$1
|
|
local path="../worktrees/$branch"
|
|
|
|
git worktree add "$path" -b "$branch"
|
|
cd "$path"
|
|
|
|
# Setup environment
|
|
npm install
|
|
cp ../.env.example .env
|
|
|
|
# Run initial build
|
|
npm run build
|
|
|
|
echo "Worktree ready: $path"
|
|
}
|
|
|
|
create_worktree_with_setup "feature/new-feature"
|
|
```
|
|
|
|
### Shared Build Cache
|
|
|
|
Optimize build times by sharing node_modules:
|
|
|
|
```bash
|
|
# Symbolic link to shared node_modules
|
|
cd ../worktrees/feature-a
|
|
ln -s ../../project/node_modules node_modules
|
|
```
|
|
|
|
## Best Practices
|
|
|
|
### 1. Organize Worktrees
|
|
|
|
Keep worktrees in a dedicated directory:
|
|
```
|
|
project/
|
|
├── .git/
|
|
├── src/
|
|
└── ../worktrees/
|
|
├── features/
|
|
│ ├── auth/
|
|
│ └── dashboard/
|
|
├── hotfixes/
|
|
│ └── security-patch/
|
|
└── reviews/
|
|
├── pr-123/
|
|
└── pr-124/
|
|
```
|
|
|
|
### 2. Naming Conventions
|
|
|
|
Use consistent naming:
|
|
- Features: `feature-{name}`
|
|
- Hotfixes: `hotfix-{issue}`
|
|
- PRs: `pr-{number}`
|
|
- Tests: `test-{scenario}`
|
|
|
|
### 3. Clean Up Regularly
|
|
|
|
Remove merged worktrees:
|
|
```bash
|
|
# After PR is merged
|
|
git worktree remove ../worktrees/feature-completed
|
|
git branch -d feature/completed
|
|
git push origin --delete feature/completed
|
|
```
|
|
|
|
### 4. Documentation
|
|
|
|
Track worktrees in your project:
|
|
```bash
|
|
# Create worktree registry
|
|
echo "# Active Worktrees" > .worktrees.md
|
|
git worktree list >> .worktrees.md
|
|
```
|
|
|
|
## Common Issues & Solutions
|
|
|
|
### Issue: "Already checked out"
|
|
```bash
|
|
# Error: branch is already checked out
|
|
# Solution: Use a worktree or checkout in different location
|
|
git worktree add --detach ../worktrees/temp
|
|
cd ../worktrees/temp
|
|
git checkout feature/branch
|
|
```
|
|
|
|
### Issue: "Worktree path exists"
|
|
```bash
|
|
# Error: directory already exists
|
|
# Solution: Remove existing directory
|
|
rm -rf ../worktrees/old-path
|
|
git worktree add ../worktrees/old-path -b new-branch
|
|
```
|
|
|
|
### Issue: Missing dependencies
|
|
```bash
|
|
# Each worktree needs its own node_modules
|
|
cd ../worktrees/new-feature
|
|
npm install
|
|
|
|
# Or use shared cache (use with caution)
|
|
npm ci --cache ../cache
|
|
```
|
|
|
|
## Performance Tips
|
|
|
|
1. **Limit Active Worktrees**: Keep 3-5 active worktrees max
|
|
2. **Share Git Objects**: Worktrees share the .git directory automatically
|
|
3. **Exclude from Backup**: Add worktrees directory to backup exclusions
|
|
4. **Use Shallow Clones**: For temporary review worktrees
|
|
5. **Clean Up Regularly**: Remove merged or abandoned worktrees
|
|
|
|
## Safety Guidelines
|
|
|
|
1. **Always commit before removing**: Ensure no uncommitted changes
|
|
2. **Check worktree status**: Use `git worktree list` before operations
|
|
3. **Avoid nested worktrees**: Don't create worktrees inside worktrees
|
|
4. **Backup important work**: Push branches before removing worktrees
|
|
5. **Use prune carefully**: Run `git worktree prune --dry-run` first
|
|
|
|
## Integration with IDEs
|
|
|
|
### VS Code
|
|
```bash
|
|
# Open worktree in new window
|
|
code ../worktrees/feature-auth
|
|
|
|
# Or add to workspace
|
|
code --add ../worktrees/feature-auth
|
|
```
|
|
|
|
### JetBrains IDEs
|
|
```bash
|
|
# Open worktree as new project
|
|
idea ../worktrees/feature-auth
|
|
```
|
|
|
|
## Methodology
|
|
|
|
Git worktrees enable efficient parallel development by:
|
|
- **Context Preservation**: Keep each branch's build and state separate
|
|
- **Quick Switching**: Move between branches instantly (just cd)
|
|
- **Parallel Builds**: Test multiple configurations simultaneously
|
|
- **Safe Experimentation**: Isolated environments for each branch
|
|
- **Efficient Reviews**: Check PRs without disrupting current work
