# WeChat Mini Program Development Guide for EcoMart

## Project Overview
EcoMart is a sustainable e-commerce Mini Program for reusable household products. Current focus: integrating a cloud-based inventory system with real-time stock updates.

## Key Implementation Steps

### 1. Project Setup
```json
{
  "appid": "wx1234567890abcdef",
  "name": "EcoMart",
  "description": "Sustainable shopping made easy",
  "permission": {
    "scope.userInfo": true,
    "scope.address": true
  }
}
```

### 2. Cloud Function Integration
```javascript
// Cloud function for inventory check
exports.main = async (event, context) => {
  const { productId } = event;
  const db = require('wx-server-sdk').database();
  
  try {
    const result = await db.collection('inventory')
      .where({ productId, active: true })
      .get();
    
    return {
      status: 'success',
      data: result.data[0].stock
    };
  } catch (error) {
    return {
      status: 'error',
      message: error.message
    };
  }
};
```

### 3. UI Component for Product Listing
```html
<view wx:for="{{products}}" wx:key="id">
  <product-card
    name="{{item.name}}"
    price="{{item.price}}"
    stock="{{item.stock}}"
    onAddToCart="handleAddToCart"
  />
</view>
```

## Debugging Tips
- Use WeChat Developer Tools for real-time console logging
- Test cloud functions with mock data before deployment
- Monitor API response times in the Mini Program admin panel
