Building a Custom Shopping Cart with React and SniptCart

In this tutorial, we'll build a fully customized shopping cart component using React and the SniptCart SDK.

Setting Up the Project

First, create a new React project and install dependencies:

npx create-react-app my-shopping-cart
cd my-shopping-cart
npm install @sniptcart/sdk

Creating the Cart Component

Let's create a custom cart component:

import { useState, useEffect } from 'react';
import { SniptCart } from '@sniptcart/sdk';

function ShoppingCart() {
  const [cart, setCart] = useState(null);
  const [items, setItems] = useState([]);

  useEffect(() => {
    const sniptCart = new SniptCart({
      apiKey: process.env.REACT_APP_SNIPTCART_API_KEY,
      environment: 'production'
    });
    
    setCart(sniptCart);
    loadCartItems();
  }, []);

  const loadCartItems = async () => {
    const cartItems = await cart.getItems();
    setItems(cartItems);
  };

  const addToCart = async (product) => {
    await cart.addItem(product);
    loadCartItems();
  };

  return (
    <div className="shopping-cart">
      <h2>Shopping Cart</h2>
      {items.map(item => (
        <div key={item.id} className="cart-item">
          <h3>{item.name}</h3>
          <p>{`$${item.price}`}</p>
          <p>Quantity: {item.quantity}</p>
        </div>
      ))}
    </div>
  );
}

Styling with Tailwind CSS

Add Tailwind CSS for beautiful styling:

<div className="bg-white rounded-lg shadow-lg p-6">
  <h2 className="text-2xl font-bold mb-4">Your Cart</h2>
  {/* Cart items */}
</div>

Next Steps

• Add quantity controls
• Implement remove item functionality
• Add checkout flow
• Style with your brand colors

This gives you a solid foundation for building a custom shopping cart!
