使用express.js将数据发送到Vue.js前端

Question

我使用Vue.js作为Frontend和Express.js作为Backend。

我的Server.js看起来像这样：

$theQuery = Customer::select(DB::raw('customers.id, customers.customer_name,SUM(s.balance) AS shipmentBalance'))
        ->leftJoin('shipments as s', function($join)
        {
            $join->on('customers.id', '=', 's.bill_to');
            $join->on(DB::raw('s.balance > 
                                (SELECT IFNULL(SUM(payments_distributions.amount),0)                
                                    FROM payments_distributions               
                                    WHERE payments_distributions.shipment_id = s.pro_number)
                            '));    
        })
        ->groupBy('customers.id', 'customers.customer_name')
        ->orderByRaw('SUM(s.balance) DESC')
        ->limit(5)
        ->get();

当我渲染dist文件夹中的index.html时，我想将一些数据发送到前端
