Today in the garden of the palace, the beloved consort was frowning at the code in her hands, and I couldn’t help but ask.
“My dear consort, what troubles you?”
“Your Majesty, I have received a task to develop a shopping cart, and I must complete it within a day. But looking at so many features to write, I am really overwhelmed!”
“Haha, my dear consort, don’t panic. Today I will teach you to use Cursor, this magical tool, and you will experience unprecedented development efficiency!”
“Cursor? What is that?”
“This is an AI-based intelligent programming assistant that can not only help you quickly write code but also provide real-time suggestions. Come, let me first guide you through the installation process.”
Step 1: Install Cursor
“First, visit cursor.sh to download the installation package. Once the installation is complete, we can start writing the shopping cart.”
“Okay! So where do we start?”
“Let’s first create the basic structure of the project. In Cursor, you just need to describe the features you want, and the AI will help you generate the code framework.”
Step 2: Create Shopping Cart Component
“Come, watch closely, we start like this:
import React, { useState } from 'react';
import './ShoppingCart.css';
function ShoppingCart() {
const [cartItems, setCartItems] = useState([]);
const [products] = useState([
{ id: 1, name: 'Royal Tea', price: 99, image: '🍵' },
{ id: 2, name: 'Imperial Fan', price: 199, image: '🌸' },
{ id: 3, name: 'Dragon Pattern Dish', price: 299, image: '🍽️' }
]);
const addToCart = (product) => {
setCartItems([...cartItems, product]);
};
return (
<div>
<h1>Imperial Goods Mall</h1>
{/* Additional content to be added */}
</div>
);
}
export default ShoppingCart;
“Wow! Your Majesty, the code is generated so quickly! But how do we write the subsequent content?”
“Don’t worry, we can let Cursor help us supplement the product list and shopping cart features. In Cursor, press Cmd/Ctrl + K, and then input your requirements.”
Step 3: Improve Shopping Cart Functionality
“Let’s add the core functionality for displaying products and the shopping cart:”
// Add the following content in the return statement
<div classname="products">
{products.map(product => (
<div key="{product.id}">
{product.image}
{product.name}
{product.price} gold
<button =="" onclick="{()"> addToCart(product)}>Add to Cart</button>
</div>
))}
</div>
<div classname="cart">
Shopping Cart
{cartItems.map((item, index) => (
<div key="{index}">
{item.name}
{item.price} gold
</div>
))}
Total: {cartItems.reduce((total, item) => total + item.price, 0)} gold
</div>
“That’s amazing! This completes the basic functionality! What about the styles?”
“Let Cursor help us generate the accompanying CSS:”
.shopping-cart {
padding: 20px;
max-width: 1200px;
margin: 0 auto;
}
.products {
display: grid;
grid-template-columns: repeat(auto-fit, minmax(250px, 1fr));
gap: 20px;
margin-bottom: 30px;
}
.product-card {
border: 1px solid #ddd;
padding: 15px;
border-radius: 8px;
text-align: center;
}
.product-image {
font-size: 48px;
margin-bottom: 10px;
}
.cart {
border-top: 2px solid #eee;
padding-top: 20px;
}
.cart-item {
display: flex;
justify-content: space-between;
padding: 10px 0;
border-bottom: 1px solid #eee;
}
.cart-total {
margin-top: 20px;
font-weight: bold;
text-align: right;
}
“Wow! This is so fast! Are there any other features missing from the shopping cart?”
“Let’s add the ability to remove items and adjust quantities:”
// Add new methods in the ShoppingCart component
const removeFromCart = (index) => {
const newCartItems = [...cartItems];
newCartItems.splice(index, 1);
setCartItems(newCartItems);
};
const updateQuantity = (index, delta) => {
const newCartItems = [...cartItems];
if (delta === -1 && newCartItems[index].quantity === 1) {
removeFromCart(index);
return;
}
newCartItems[index].quantity = (newCartItems[index].quantity || 1) + delta;
setCartItems(newCartItems);
};
“Now our shopping cart functionality is quite complete! My dear consort, see, using Cursor not only speeds up development but also improves code quality!”
“That’s great! Are there any tips for using it?”
“Of course! When using Cursor, you can:”
- Describe the features you want in natural language
- Let the AI refactor or optimize your code
- Ask questions about points in the code
- Request to generate test cases
“I see! With this magical tool Cursor, I no longer have to worry about not completing my tasks!”
“That’s right, remember this: To do a good job, one must sharpen their tools. Alright, today’s lesson ends here, my dear consort, you must practice well!”
“Thank you, Your Majesty! I will go practice right away!”
Watching the beloved consort leave happily, I couldn’t help but feel that with modern development tools, programming has truly become more enjoyable!
