Post-checkout Hooks

Post-checkout hooks run after git checkout operations, useful for updating the working directory based on the new branch.

Use Cases

• Install/update dependencies
• Clear cache files
• Update configuration files
• Restart development servers

Example Hook

#!/bin/bash
# .git/hooks/post-checkout

# Check if package.json changed
if git diff --name-only HEAD@{1} HEAD | grep -q "package.json"; then
    echo "package.json changed, running npm install..."
    npm install
fi
