Solution 1:[1]

If you click on the Delivered button, you will reduce the quantity one by one, then you will send that value to the backend and update it in the database. Increase in the same way.

as like...

const stockQuantity = parseInt(products?.quantity) const newStockQuantity = stockQuantity - 1;

then

fetch(url, { method: 'PUT', // or 'PUT' headers: { 'Content-Type': 'application/json', }, body: JSON.stringify( { quantity: newStockQuantity, } ), }) .then(response => response.json()) .then(data => { console.log('Success:', data); toast('Your Product Deliver successfully') setIsReload(!reload) })

const delevary = e => {

    const quantity = product?.quantity
    const updateItem = {quantity}
    const url = `http://localhost:7000//${id}`;
    fetch(url,{
        method : 'PUT',
        headers : {
            'content-type' : 'application/json'
        },
        body : JSON.stringify(updateItem)
    })
    .then(res => res.json())
    .then (result =>{
        console.log(result)
        setIsreload(!isReload)
        // setItems(result);
    })
        
    
};
