Expected outcome:

GET /api/products - List all products
GET /api/products/:id - Get single product
POST /api/products - Create product
PUT /api/products/:id - Replace product
PATCH /api/products/:id - Update product
DELETE /api/products/:id - Delete product

Query params: ?status=active&sort=price&limit=20&offset=0

Expected outcome:

Instead of:
for (const order of orders) {
order.customer = await getCustomer(order.customerId)
}

Use:
const customerIds = orders.map(o => o.customerId)
const customers = await getCustomers(customerIds)
const customerMap = new Map(customers.map(c => [c.id, c]))
orders.forEach(o => o.customer = customerMap.get(o.customerId))

Expected outcome:

export function verifyToken(token: string) {
try {
return jwt.verify(token, process.env.JWT_SECRET!)
} catch (error) {
throw new ApiError(401, 'Invalid token')
}
}

export async function requireAuth(request: Request) {
const token = request.headers.get('authorization')?.replace('Bearer ', '')
if (!token) throw new ApiError(401, 'Missing token')
return verifyToken(token)
}
