Introduction to Inventory Management Systems

In today’s fast-paced digital environment, businesses require efficient inventory management systems to streamline operations. These systems not only help in tracking stock levels but also in managing orders, deliveries, and sales data. Developing an inventory management system with React can make this process efficient, user-friendly, and responsive.

Setting Up the Project

To start, you need to set up your React project. You can easily do this using Create React App with Vite. Open your terminal and run

$ npm create vite@latest

Select as React from the following list and and install it.

App.jsx

import React, { useState } from "react";


function App() {
  const [selectedItem, setSelectedItem] = useState(null);
  const [qty, setQty] = useState(1);
  const [cart, setCart] = useState([]);
  const [total, setTotal] = useState(0);

  const items = {
    Chocolate: { price: 32, image: "images/ice1.jpg" },
    Mango: { price: 35, image: "images/ice2.jpg" },
    Venila: { price: 40, image: "images/ice3.jpg" },
    Strawberry: { price: 45, image: "images/ice4.jpg" },
    MixFruit: { price: 35, image: "images/ice5.jpg" },
  };

  const handleItemClick = (item) => {
    setSelectedItem(item);
  };

  const handleAddToCart = () => {
    if (selectedItem && qty > 0) {
      const price = items[selectedItem].price;
      const totalAmount = price * qty;

      setCart([
        ...cart,
        { name: selectedItem, price, qty, totalAmount },
      ]);

      setTotal(total + totalAmount);
      setQty(1);
      setSelectedItem(null);
    }
  };

  const handleDelete = (index) => {
    const removedItem = cart[index];
    setCart(cart.filter((_, i) => i !== index));
    setTotal(total - removedItem.totalAmount);
  };

  const handleReset = () => {
    setCart([]);
    setTotal(0);
  };
