Interactive Setup

The CLI will guide you through the setup process:

1. Project Name: Enter the name of your project
2. Language: Choose between TypeScript or JavaScript
3. Template: Select one of the available templates
4. Router: Choose whether to add ShadowJS Router for client-side routing
5. TailwindCSS: Choose whether to use TailwindCSS v4 for styling
6. Git Repository: Choose whether to initialize a git repository

Project Structure

After setup, your project will have this structure:

my-app/
├── index.html
├── package.json
├── vite.config.js (or vite.config.ts if TypeScript selected)
├── tsconfig.json (if TypeScript selected)
└── src/
    ├── main.jsx (or main.tsx if TypeScript selected)
    ├── App.jsx (or App.tsx if TypeScript selected)
    ├── style.css (or tailwind.css if TailwindCSS selected)
    └── vite-env.d.ts (if TypeScript selected)

Note: If you choose TailwindCSS, the style.css file will contain TailwindCSS imports and pre-configured styles instead of traditional CSS.

Getting Started

After creating your project:

cd my-app
npm install
npm run dev

Your app will be running at http://localhost:3000

Features

Git Integration

When you choose to initialize a git repository, the CLI will:

• Run git init in your project directory
• Add all project files to git
• Create an initial commit with the message "Initial commit"

Router Integration

When you choose to add ShadowJS Router, the CLI will:

• Add @shadow-js/router as a dependency
• Set up a simple router configuration in main.jsx (or main.tsx if TypeScript selected)
• Create a route for the root path (/) that renders your App component
• Update the App component to work with the router

This provides a foundation for building multi-page applications with client-side routing.

TailwindCSS Integration

When you choose to use TailwindCSS, the CLI will:

• Add tailwindcss and @tailwindcss/vite as dependencies
• Configure Vite to use the TailwindCSS plugin
• Set up a tailwind.css file with Tailwind imports and pre-configured styles
• Include utility classes and component styles for your chosen template

The TailwindCSS setup includes:

• Base styles: Reset and typography using Tailwind's base layer
• Component styles: Pre-styled components for cards, buttons, and layouts
• Utility classes: Common patterns used in the template
• Responsive design: Mobile-first responsive utilities

You can start using TailwindCSS classes immediately in your JSX/TSX components:

function MyComponent() {
  return (
    <div className="bg-white rounded-lg shadow-lg p-6">
      <h2 className="text-2xl font-semibold text-gray-800 mb-4">Hello World</h2>
      <button className="bg-blue-500 hover:bg-blue-600 text-white font-bold py-2 px-4 rounded">
        Click me
      </button>
    </div>
  );
}
