# 🎨 Visual Builder Implementation Plan
|
||||
## Craft.js + AstroWind + Direct DB Shim
|
||||
|
||||
**Objective:** Build a "Squarespace-style" visual editor that saves directly to PostgreSQL via the Shim, without CMS overhead.
|
||||

|
||||
## 🏗️ ARCHITECTURE
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────────────┐
|
||||
│ PUBLIC SITE (SSR - Lightning Fast) │
|
||||
│ https://[site-domain]/[slug] │
|
||||
│ - Reads sites.config JSONB │
|
||||
│ - Renders AstroWind components │
|
||||
│ - Zero editor overhead │
|
||||
└─────────────────────────────────────────────────────────┘
|
||||
▲
|
||||
│ Reads config
|

┌─────────────────────────────────────────────────────────┐
|
||||
│ VISUAL EDITOR (React + Craft.js) │

|
||||
## 🔧 CORE COMPONENTS
|
||||
|
||||
### 1. Editor Canvas (`EditorCanvas.tsx`)
|
||||
|
||||
```typescript
|
||||
import { Editor, Frame, Element } from '@craftjs/core';
|
||||
import { HeroBlock, FeaturesBlock, ContentBlock } from './blocks';
|
||||
|
||||
export default function EditorCanvas({ initialState, siteId }) {
|
||||
const handleSave = async (json) => {
|
||||
await fetch(`/api/shim/sites/save-config`, {
|
||||
method: 'POST',
|
||||
body: JSON.stringify({ siteId, config: json })
|
||||
});
|
||||
};
|
||||
|
||||
return (
|
||||
<Editor resolver={{ HeroBlock, FeaturesBlock, ContentBlock }}>
|
||||
<div className="flex h-screen">
|
||||
<ToolboxPanel />
|
||||
<div className="flex-1">
|
||||
<TopBar onSave={handleSave} />
|
||||
<Frame json={initialState}>
|
||||
<Element is="div" canvas>
|
||||
{/* Editable canvas */}
|
||||
</Element>
|
||||
</Frame>
|
||||
</div>
|
||||
<SettingsPanel />
|
||||
</div>
|
||||
</Editor>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### 2. User Component Example (`HeroBlock.tsx`)
|
||||
|
||||
```typescript
|
||||
import { useNode } from '@craftjs/core';
|
||||
|
||||
export const HeroBlock = ({ title, subtitle, image, ctaText }) => {
|
||||
const { connectors: { connect, drag } } = useNode();
|
||||
|
||||
return (
|
||||
<div ref={ref => connect(drag(ref))} className="hero">
|
||||
<h1>{title}</h1>
|
||||
<p>{subtitle}</p>
|
||||
{image && <img src={image} alt={title} />}
|
||||
<button>{ctaText}</button>
|
||||
</div>
|
||||
);
|
||||
};
|
||||
|
||||
HeroBlock.craft = {
|
||||
props: {
|
||||
title: 'Hero Title',
|
||||
subtitle: 'Hero subtitle',
|
||||
image: '/placeholder.jpg',
|
||||
ctaText: 'Get Started'
|
||||
},
|
||||
rules: {
|
||||
canDrag: true,
|
||||
canDrop: false
|
||||
},
|
||||
related: {
|
||||
settings: HeroSettings // Property panel component
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
### 3. Save Config API (`save-config.ts`)
|
||||
|
||||
```typescript
|
||||
import type { APIRoute } from 'astro';
|
||||
import { updateSite } from '@/lib/shim/sites';
|
||||
|
||||
export const POST: APIRoute = async ({ request }) => {
|
||||
try {
|
||||
const { siteId, config } = await request.json();
|
||||
|
||||
// Update site config via Shim
|
||||
await updateSite(siteId, {
|
||||
config: JSON.stringify(config)
|
||||
});
|
||||
|
||||
return new Response(JSON.stringify({ success: true }), {
|
||||
status: 200
|
||||
});
|
||||
} catch (error) {
|
||||
return new Response(JSON.stringify({ error: error.message }), {
|
||||
status: 500
|
||||
});
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
### 4. Public Renderer (`[...slug].astro`)
|
||||
|
||||
```astro
|
||||
---
|
||||
import { getSiteByDomain } from '@/lib/shim/sites';
|
||||
import { renderBlocks } from '@/lib/templates/renderer';
|
||||
|
||||
const site = await getSiteByDomain(Astro.url.hostname);
|
||||
const config = site?.config || {};
|
||||
const blocks = config.blocks || [];
|
||||
---
|
||||
|
||||
<html>
|
||||
<body>
|
||||
{renderBlocks(blocks)}
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🎨 TEMPLATE FACTORY STRUCTURE
|
||||
|
||||
### Default Templates
|
||||
|
||||
| Template | Blocks | Use Case |
|
||||
|----------|--------|----------|
|
||||
| **Corporate** | Hero + Features + Stats + Team + CTA | Business sites |
|
||||
| **Landing** | Hero + Benefits + Testimonials + Pricing + CTA | SaaS landing pages |
|
||||
| **Blog** | Header + Posts Grid + Sidebar + Footer | Content sites |
|
||||
| **Portfolio** | Hero + Projects Grid + About + Contact | Personal branding |
|
||||
|
||||
### JSONB Structure
|
||||
|
||||
```json
|
||||
{
|
||||
"template": "astrowind",
|
||||
"theme": {
|
||||
"primaryColor": "#3B82F6",
|
||||
"font": "Inter"
|
||||
},
|
||||
"blocks": [
|
||||
{
|
||||
"id": "hero-1",
|
||||
"type": "Hero",
|
||||
"props": {
|
||||
"title": "Welcome to Our Site",
|
||||
"subtitle": "Build amazing things",
|
||||
"ctaText": "Get Started",
|
||||
"ctaLink": "/signup"
|
||||
}
|
||||
},
|
||||
{
|
||||
"id": "features-1",
|
||||
"type": "Features",
|
||||
"props": {
|
||||
"title": "Key Features",
|
||||
"items": [
|
||||
{ "icon": "⚡", "title": "Fast", "description": "Lightning quick" },
|
||||
{ "icon": "🔒", "title": "Secure", "description": "Bank-level security" }
|
||||
]
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔒 SECURITY MODEL
|
||||
|
||||
1. **Editor Access:**
|
||||
- Only accessible at `/admin/editor/[id]`
|
||||
- Requires `GOD_MODE_TOKEN` validation
|
||||
- Token checked in Astro middleware
|
||||
|
||||
2. **Save Operations:**
|
||||
- All saves go through Shim (`/api/shim/sites/save-config`)
|
||||
- Zod validation on JSONB structure
|
||||
- Sanitize user input before SQL
|
||||
|
||||
3. **Public Rendering:**
|
||||
- No editor JavaScript loaded
|
||||
- Pure SSR from JSONB config
|
||||
- No exposure of admin endpoints
|
||||
|
||||
---
|
||||
|
||||
## 📊 PERFORMANCE COMPARISON
|
||||
|
||||
| Operation | Traditional CMS | God Mode Visual Builder |
|
||||
|-----------|----------------|-------------------------|
|
||||
| **Load Editor** | ~2000ms (API + DB + Render) | ~300ms (Direct DB) |
|
||||
| **Save Changes** | ~1500ms (API → CMS → DB) | ~50ms (Shim → DB) |
|
||||
| **Public Page Load** | ~800ms (CMS overhead) | ~10ms (Pure SSR) |
|
||||
| **Scale** | 100s of sites | 10,000s of sites |
|
||||
|
||||
