Set up a hot-reloading development server for instant code changes. Your task: 1. Detect the project type and framework: - React/Vue/Angular (Vite, Webpack, etc.) - Node.js/Express (nodemon, node --watch) - Python (Flask/Django with auto-reload) - Static sites (live-server, browser-sync) 2. Configure hot reloading based on the stack: - Install necessary dev dependencies - Update configuration files - Set up file watching - Configure port and proxy settings 3. Create or update dev scripts: ```json "scripts": { "dev": "appropriate-dev-server --watch", "start": "production-command" } ``` 4. Optimize for performance: - Configure file watch patterns - Exclude unnecessary directories - Set up source maps - Enable HMR (Hot Module Replacement) if available 5. Document the dev server usage: - How to start the dev server - Available options and flags - Port configuration - Troubleshooting common issues Ensure instant feedback on code changes for optimal development workflow.
