货币Vue.js过滤Laravel错误：使用未定义的常量货币 - 假设为“货币”

Question

The Vue filter for showing currency is not working. I want to show currencies with Vue.js in my HTML code.

And I got an error:

Use of undefined constant currency - assumed 'currency' (this will throw an Error in a future version of PHP) (0)

My code in transaksi.js:

 Vue.filter('currency', function (money) {
   return accounting.formatMoney(money, "Rp ", 2, ".", ",")
})

And in HTML tag:

<td>Rp. {{ $product->price | curency  }}</td>
