I have a small restaurant app which lets users order from a menu. The menu has three types: food, drink, dessert. The component structure from top to bottom is Order -> Menu -> MenuItem. I want to separate the menu page based on type (example: all food items are under a title called FOOD and so on). Right now, the Menu component receives the menu array as a prop from Order and renders MenuItem for each item in the array. Each item has a property called type. I omitted certain parts of the code unrelated to this issue for brevity.
//Order
export default function Order() {
const [menu, setMenu] = useState<Array<{}>>([]);
const [total, setTotal] = useState(0);
useEffect(() => {
apiFetch("menu").then((json) => setMenu(json.menu));
}, []);
async function handleSubmit(e: any) {
e.preventDefault();
const selectedItems = getSelectedItems(TotalStore);
apiFetch("order", "post", { selectedItems })
.then((json) => {
alert("Order has been submitted");
setTotal(0);
TotalStore.reset();
localStorage.setItem("last_order_id", json.order.id);
function checkOrderStatus() {
apiFetch(
`order/${json.order.id || localStorage.getItem("last_order_id")}`
).then((placedOrder) => {
const { order } = placedOrder;
if (order[0].status === 2) {
alert("Your order is ready!");
} else {
setTimeout(checkOrderStatus, 5000);
}
});
}
checkOrderStatus();
})
.catch((error) => {
alert("Server error");
});
}
function orderPlaced(total: number) {
return total !== 0 ? true : false;
}
return (
<div>
{menu.length > 0 ? (
<>
<div className="menu">
<div className="menu-title">Food Menu</div>
<form id="menu-form" onSubmit={handleSubmit} autoComplete="off">
<Menu onChange={itemChanged} props={menu} />
<button type="submit" disabled={!orderPlaced(total)}>
Place Order
</button>
</form>
</div>
<div className="order-total">
<h2>
Total: $<span>{total.toFixed(2)}</span>
</h2>
</div>
</>
) : (
<>Loading Menu</>
)}
</div>
);
}
//Menu
export default function Menu({ onChange, props }: MenuProps) {
return (
<div>
{props.map((food: any, index: number) => {
return (
<MenuItem
key={index}
onChange={onChange}
type={food.type}
item={food}
/>
);
})}
</div>
);
}
//MenuItem
export default function MenuItem({ onChange, item, type }: MenuItemProps) {
return (
<div>
<article className="menu-item" data-item-type={type}>
<h3 className="item-name">{item.name}</h3>
<input
type="number"
className="menu-item-count"
min="0"
value={data.count}
onChange={menuItemCountChange}
/>
<strong className="item-price">${item.price.toFixed(2)}</strong>
</article>
</div>
);
}
