# WHP Site Builder v2

A visual drag-and-drop website builder for WHP, rebuilt from the ground up with Craft.js, React 18, and TypeScript. Replaces the legacy GrapesJS-based editor.

## Quick Start

```bash
npm install
npm run dev
```

Opens at http://localhost:5173. The editor runs in standalone mode without WHP integration.

## Build and Deploy

```bash
# Build production bundle
npm run build

# Deploy to WHP
cp dist/index.html /docker/whp/web/site-builder/editor.html
cp -r dist/js/ /docker/whp/web/site-builder/js/
cp -r dist/css/ /docker/whp/web/site-builder/css/
```

The PHP wrapper (`index.php`) injects `WHP_CONFIG` (user session, CSRF token, site ID) into the HTML before serving.

## Architecture

- **Craft.js** - React-based visual editor framework (no iframe, direct DOM rendering)
- **Inline styles** - All user content uses React CSSProperties, no class-based CSS
- **Component pattern** - Each component is a self-contained file with: render logic, settings panel, Craft.js config, and HTML export method
- **3-panel layout** - Left (blocks/pages/layers/assets), Center (canvas with device preview), Right (styles/settings/head)
- **Dark theme** - CSS custom properties, Inter font, blue accent

## Components (22)
