# Rynex Framework

A minimalist TypeScript framework for building reactive web applications with no Virtual DOM.

## Features

- **No Virtual DOM**: Direct DOM manipulation for maximum performance
- **Reactive State**: Proxy-based reactivity with automatic UI updates
- **File-Based Routing**: Next.js style routing with dynamic routes
- **TypeScript First**: Full type safety out of the box
- **Zero Configuration**: Sensible defaults, works immediately
- **Production Ready**: Express server with native HTTP fallback
- **Hot Module Replacement**: Instant feedback during development
- **Automatic Cache-Busting**: Always serve fresh content to users on deployment
- **Tiny Bundle**: Approximately 15KB gzipped

## Quick Start

```bash
# Create new project
npx rynex init my-app
cd my-app

# Install dependencies
pnpm install

# Start development server
pnpm dev
```

Your application will be running at `http://localhost:3000`

## Example

### Simple Counter Component

```typescript
import { state } from 'rynex';
import * as UI from 'rynex';

export default function Counter() {
  const counterState = state({ count: 0 });

  return UI.vbox({
    style: { padding: '2rem', gap: '1rem' }
  }, [
    UI.text({}, () => `Count: ${counterState.count}`),
    UI.hbox({ style: { gap: '0.5rem' } }, [
      UI.button({
        onClick: () => counterState.count--
      }, 'Decrement'),
      UI.button({
        onClick: () => counterState.count++
      }, 'Increment')
    ])
  ]);
}
```

## Core Concepts

### Reactive State Management

```typescript
import { state, computed, effect } from 'rynex';

// Create reactive state
const appState = state({
  count: 0,
  name: 'John'
});

// Computed values
const doubled = computed(() => appState.count * 2);

// Side effects
effect(() => {
  console.log('Count changed:', appState.count);
});

// Updates trigger automatic re-renders
appState.count++;
```

### File-Based Routing

Organize pages by file structure:

```
src/pages/
├── index.ts              # Route: /
├── about.ts              # Route: /about
├── blog/
│   ├── page.ts           # Route: /blog
│   └── [slug]/
│       └── page.ts       # Route: /blog/:slug (dynamic)
└── user/
    └── [id]/
        └── page.ts       # Route: /user/:id (dynamic)
```

### Dynamic Routes

```typescript
import * as UI from 'rynex';
import { RouteContext } from 'rynex';

export default function UserPage(ctx: RouteContext) {
  const userId = ctx.params.id;
  
  return UI.vbox({
    style: { padding: '2rem' }
  }, [
    UI.h1({}, `User Profile: ${userId}`),
    UI.text({}, `Viewing profile for user ${userId}`),
    UI.link({ href: '/' }, 'Go Home')
  ]);
}
```

## CLI Commands

```bash
# Create new project
rynex init [project-name]

# Start development server with HMR
rynex dev

# Build for production
rynex build

# Start production server
rynex start

# Add integrations (e.g., Tailwind CSS)
rynex add tailwind

# Clean build artifacts
rynex clean
```

## Styling with Tailwind CSS

Rynex supports Tailwind CSS out of the box with a simple opt-in setup:

```bash
# Add Tailwind CSS to your project
rynex add tailwind

# Choose your package manager (npm/pnpm/yarn/bun)
# The command will:
# - Install tailwindcss, postcss, and autoprefixer
# - Create tailwind.config.js
# - Configure your CSS files
# - Add necessary imports

# Start development
pnpm dev
```

### Using Tailwind Classes

```typescript
import * as UI from 'rynex';

export default function App() {
  return UI.container({
    class: 'flex items-center justify-center min-h-screen bg-gray-100'
  }, [
    UI.vbox({
      class: 'bg-white p-8 rounded-lg shadow-lg max-w-md'
    }, [
      UI.text({
        class: 'text-3xl font-bold text-gray-800 mb-4'
      }, 'Hello Tailwind!'),
      UI.button({
        class: 'bg-blue-500 hover:bg-blue-600 text-white px-6 py-3 rounded-lg transition-colors',
        onClick: () => console.log('Clicked!')
      }, 'Get Started')
    ])
  ]);
}
```

**Features:**
- ✅ Automatic class detection in `class: 'flex'` syntax
- ✅ JIT mode for fast compilation
- ✅ Hot reload in development
- ✅ Auto-purging in production
- ✅ Latest Tailwind CSS v4.x

## Configuration

Create `rynex.config.js` in your project root:

```javascript
export default {
  entry: 'src/index.ts',
  output: 'dist/bundle.js',
  port: 3000,
  minify: true,
  sourceMaps: true,
  hotReload: true,
  
  // Routing configuration
  routing: {
    mode: 'history',
    fileBasedRouting: true,
    pagesDir: 'src/pages',
    scrollBehavior: 'smooth'
  },
  
  // Build configuration
  build: {
    splitting: true,
    chunkSize: 500,
    publicPath: '/'
  }
};
```

## Design Philosophy

1. **Simplicity First**: No complex build configurations
2. **Direct DOM**: No Virtual DOM overhead
3. **Reactive by Default**: State changes automatically update UI
4. **TypeScript Native**: Built with TypeScript for TypeScript
5. **Performance**: Minimal runtime with efficient updates
6. **Developer Experience**: Hot reload, source maps, clear errors

## Performance

- No Virtual DOM diffing overhead
- Direct DOM updates
- Lazy loading support
- Code splitting
- Tree shaking
- Minification
- Compression (with Express)

## Browser Support

- Chrome (latest)
- Firefox (latest)
- Safari (latest)
- Edge (latest)
