## 📝 How to Add a New Feature
|
||
|
|
|
||
|
|
### Example: Add "Wishlist" Feature
|
||
|
|
|
||
|
|
#### Backend Steps
|
||
|
|
|
||
|
|
1. **Update Database Schema** (`backend/prisma/schema.prisma`):
|
||
|
|
|
||
|
|
```prisma
|
||
|
|
model Wishlist {
|
||
|
|
id Int @id @default(autoincrement())
|
||
|
|
userId Int
|
||
|
|
productId Int
|
||
|
|
createdAt DateTime @default(now())
|
||
|
|
|
||
|
|
user User @relation(fields: [userId], references: [id])
|
||
|
|
product Product @relation(fields: [productId], references: [id])
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
1. **Run Migration**:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npx prisma migrate dev --name add_wishlist
|
||
|
|
```
|
||
|
|
|
||
|
|
1. **Create Service** (`backend/src/services/wishlistService.ts`):
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
import { prisma } from '../config/database';
|
||
|
|
|
||
|
|
export async function addToWishlist(userId: number, productId: number) {
|
||
|
|
return await prisma.wishlist.create({
|
||
|
|
data: { userId, productId }
|
||
|
|
});
|
||
|
|
}
|
||
|
|
|
||
|
|
export async function getUserWishlist(userId: number) {
|
||
|
|
return await prisma.wishlist.findMany({
|
||
|
|
where: { userId },
|
||
|
|
include: { product: true }
|
||
|
|
});
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
1. **Create Controller** (`backend/src/controllers/wishlistController.ts`):
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
import { Request, Response } from 'express';
|
||
|
|
import * as wishlistService from '../services/wishlistService';
|
||
|
|
import { sendSuccess } from '../helpers/response';
|
||
|
|
|
||
|
|
export async function addItem(req: AuthRequest, res: Response) {
|
||
|
|
const { productId } = req.body;
|
||
|
|
const userId = req.user!.userId;
|
||
|
|
|
||
|
|
const item = await wishlistService.addToWishlist(userId, productId);
|
||
|
|
sendSuccess(res, item, 'Added to wishlist', 201);
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
1. **Create Routes** (`backend/src/routes/wishlist.ts`):
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
import { Router } from 'express';
|
||
|
|
import { authenticate } from '../middlewares/authenticate';
|
||
|
|
import * as wishlistController from '../controllers/wishlistController';
|
||
|
|
|
||
|
|
const router = Router();
|
||
|
|
|
||
|
|
router.post('/', authenticate, wishlistController.addItem);
|
||
|
|
router.get('/', authenticate, wishlistController.getItems);
|
||
|
|
|
||
|
|
export default router;
|
||
|
|
```
|
||
|
|
|
||
|
|
1. **Mount Routes** (`backend/src/server.ts`):
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
import wishlistRoutes from './routes/wishlist';
|
||
|
|
app.use('/api/wishlist', wishlistRoutes);
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Frontend Steps
|
||
|
|
|
||
|
|
1. **Add Types** (`frontend/src/@types/index.ts`):
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
export interface WishlistItem {
|
||
|
|
id: number;
|
||
|
|
productId: number;
|
||
|
|
product: Product;
|
||
|
|
createdAt: string;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
1. **Create API Client** (`frontend/src/api/wishlist.ts`):
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
import apiClient from './client';
|
||
|
|
|
||
|
|
export const wishlistApi = {
|
||
|
|
async getAll() {
|
||
|
|
const response = await apiClient.get('/wishlist');
|
||
|
|
return response.data.data;
|
||
|
|
},
|
||
|
|
|
||
|
|
async add(productId: number) {
|
||
|
|
const response = await apiClient.post('/wishlist', { productId });
|
||
|
|
return response.data.data;
|
||
|
|
},
|
||
|
|
};
|
||
|
|
```
|
||
|
|
|
||
|
|
1. **Create Hook** (`frontend/src/hooks/useWishlist.ts`):
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
import { useState } from 'react';
|
||
|
|
import { wishlistApi } from '../api/wishlist';
|
||
|
|
|
||
|
|
export function useWishlist() {
|
||
|
|
const [items, setItems] = useState([]);
|
||
|
|
|
||
|
|
const addToWishlist = async (productId: number) => {
|
||
|
|
await wishlistApi.add(productId);
|
||
|
|
// Refetch items...
|
||
|
|
};
|
||
|
|
|
||
|
|
return { items, addToWishlist };
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
1. **Use in Component** (`frontend/src/components/WishlistButton.tsx`):
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
import { useWishlist } from '../hooks/useWishlist';
|
||
|
|
|
||
|
|
export function WishlistButton({ productId }) {
|
||
|
|
const { addToWishlist } = useWishlist();
|
||
|
|
|
||
|
|
return (
|
||
|
|
<button onClick={() => addToWishlist(productId)}>
|
||
|
|
Add to Wishlist
|
||
|
|
</button>
|
||
|
|
);
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
## 🔄 Data Flow Example
|
||
|
|
|
||
|
|
```
|
||
|
|
User clicks "Add to Cart" button
|
||
|
|
↓
|
||
|
|
Component calls `productApi.addToCart(id)`
|
||
|
|
↓
|
||
|
|
API client sends POST /api/cart with JWT token
|
||
|
|
↓
|
||
|
|
Backend: authenticate middleware verifies token
|
||
|
|
↓
|
||
|
|
Backend: validateCart middleware validates request
|
||
|
|
↓
|
||
|
|
Backend: cartController.addItem() receives request
|
||
|
|
↓
|
||
|
|
Backend: cartService.addItem() handles business logic
|
||
|
|
↓
|
||
|
|
Backend: cartModel (Prisma) saves to database
|
||
|
|
↓
|
||
|
|
Backend: returns { success: true, data: cart }
|
||
|
|
↓
|
||
|
|
Frontend: receives response, updates UI
|
||
|
|
↓
|
||
|
|
User sees success message
|
||
|
|
```
|
