## 🚀 Quick Start
### Create Your First Component
1. Create folder:
```bash
mkdir -p packages/my_package/component
```
2. Create `metadata.json`:
```json
{
"entityType": "component",
"description": "My components",
"components": [{ "id": "comp_my_button", "name": "My Button" }]
}
```
3. Create `components.json`:
```json
[
{
"id": "comp_my_button",
"name": "My Button",
"category": "form",
"template": {
"type": "Button",
"props": { "variant": "{{variant}}" },
"children": "{{label}}"
},
"props": { "label": "Click Me", "variant": "primary" }
}
]
```
4. Use in page:
```json
{
"type": "comp_my_button",
"props": { "label": "Save" }
}
```
5. Bootstrap:
```bash
POST http://localhost:3000/api/bootstrap
```

## 🛠️ Key Tools & Files
### Component Registry
**File**: `/frontends/nextjs/src/lib/fakemui-registry.ts`
Type-safe registry of all 151+ fakemui components:
```typescript
import { FAKEMUI_REGISTRY, getFakemUIComponent } from '@/lib/fakemui-registry'
const Button = getFakemUIComponent('Button')
const formComponents = FAKEMUI_CATEGORIES['form']
```
### JSON Renderer
**File**: `/frontends/nextjs/src/lib/packages/json/render-json-component.tsx`
Renders JSON component definitions to React:
```typescript
import { renderJSONComponent } from '@/lib/packages/json/render-json-component'
export default async function Page() {
const component = await db.components.findOne({ id })
return renderJSONComponent(component, props)
}
```
### Example Components
**File**: `/packages/ui_home/component/ui-components.json`
5 example components demonstrating all patterns:
- Home Button - Simple button with props
- Feature Card - Card with nested content
- Hero Section - Large hero component
- Contact Form - Form with fields
- Feature Grid - Responsive grid layout
