Ways to determine the overall cost of a shopping cart using Vuejs Vuex

Running a business requires managing various aspects, including tracking the inventory. In my store, I have an array called basketContents that contains items with their respective quantities and prices.

An example of how it looks is:

state: {
basketContents: [
{
     name: .....
     quantity: 2
     price:1000
},
{
     name: .....
     quantity: 6
     price:120
},
.........
   ]
}

I am looking for a way to dynamically calculate the total price of all the items in the basket and display it in a component. Is there a straightforward method to achieve this? It's important that the total price updates automatically whenever the quantity of an item changes since I want to provide accurate information to my customers. As someone who is new to this process, any guidance or advice on how to approach this task would be greatly appreciated.

 Getters: {
    SumTotal: state => {
      return state.cartItems.reduce((total, item) => total + item.quantity * item.price, 0) 
    }
  }

This code snippet calculates the total sum of items in the shopping cart.

To implement this in your project, add the following to your .vue file:

import { mapGetters } from 'vuex';
// Add the getters to your computed properties using object spread operator
...mapGetters([
   'SumTotal'
])

To display the overall sum, define a computed function called totalAmount in the component:

  computed: {
    totalAmount() {
        return this.$store.state.cartItems.reduce(
            (accumulator, currentValue) => accumulator + currentValue.quantity * currentValue.price,
            0
        );
    },
  },
};

            0
