// React POS transaction component
import { useState } from "react";
interface CartItem {
id: string;
name: string;
price: number;
qty: number;
}
export function POSTerminal() {
const [cart, setCart] = useState<CartItem[]>([]);
const addToCart = (item: CartItem) => {
setCart((prev) => {
const existing = prev.find((i) => i.id === item.id);
if (existing) {
return prev.map((i) =>
i.id === item.id ? { ...i, qty: i.qty + 1 } : i
);
}
return [...prev, { ...item, qty: 1 }];
});
};
const total = cart.reduce((sum, i) => sum + i.price * i.qty, 0);
return (
<div className="pos-terminal">
<CartDisplay items={cart} total={total} />
<PaymentPanel amount={total} />
</div>
);
