Building a Full-Stack Application with CloudScape and AWS Amplify
Let's explore a practical example of building a full-stack application using CloudScape and AWS Amplify. We'll create a simple e-commerce application that allows users to browse products, add items to their cart, and complete checkout.
1. Project Setup:
- Initialize an Amplify Project: Use the Amplify CLI to initialize a new project:
amplify init - Install CloudScape: Install the CloudScape library in your project:
npm install cloudscape
2. Define Cloud Infrastructure:
- Create an AWS S3 Bucket: Use CloudScape to create an S3 bucket for storing product images:
import { S3 } from 'cloudscape/aws'; const bucketName = 'my-ecommerce-images'; const bucket = new S3(bucketName); await bucket.create(); - Create an AWS DynamoDB Table: Define a DynamoDB table to store product information:
import { DynamoDB } from 'cloudscape/aws'; const tableName = 'products'; const table = new DynamoDB(tableName, { primaryKey: 'productId', attributes: { productName: { type: 'string' }, productPrice: { type: 'number' }, productImage: { type: 'string' }, }, }); await table.create();
3. Build the Front-End with Amplify:
- Create a React Application: Utilize the Amplify CLI to generate a React application:
amplify add ui - Use Amplify UI Components: Implement the front-end using Amplify UI components for user authentication, product display, shopping cart, and checkout functionality.
- Interact with DynamoDB: Use Amplify's data layer to interact with the DynamoDB table for fetching and updating product information.
4. Build the Back-End with Amplify:
- Create an API Endpoint: Use Amplify to create an API endpoint for handling shopping cart operations:
amplify add api - Use Lambda Functions: Implement Lambda functions to handle API requests and interact with DynamoDB to manage shopping cart items.
5. Deploy the Application:
- Deploy Infrastructure: Utilize CloudScape to deploy the defined AWS infrastructure resources.
- Deploy the Front-End and Back-End: Use Amplify to deploy the React application and API endpoints.
Example Code Snippet:
// Front-End (React with Amplify UI Components)
import { useState } from 'react';
import { API, Storage } from 'aws-amplify';
const App = () => {
const [products, setProducts] = useState([]);
useEffect(() => {
const fetchProducts = async () => {
const data = await API.get('products', '/products');
setProducts(data.items);
};
fetchProducts();
}, []);
const handleAddToCart = async (productId) => {
// Add product to shopping cart (using Amplify API)
await API.post('shoppingCart', `/addToCart/${productId}`);
};
return (
<div>
<h1>E-Commerce Store</h1>
<ul>
{products.map((product) => (
<li key={product.productId}>
<img src={await Storage.get(product.productImage)} alt={product.productName} />
<h2>{product.productName}</h2>
<p>${product.productPrice}</p>
<button onClick={() => handleAddToCart(product.productId)}>Add to Cart</button>
</li>
))}
</ul>
</div>
);
};
// Back-End (Amplify API with Lambda Functions)
const addToCart = async (event) => {
const productId = event.pathParameters.productId;
// Get user information (using Amplify Auth)
const user = await Auth.currentAuthenticatedUser();
// Update DynamoDB (using Amplify DataStore)
await DataStore.save(
new ShoppingCartItem({
userId: user.attributes.sub,
productId,
})
);
return {
statusCode: 200,
body: JSON.stringify({ message: 'Product added to cart' }),
};
};
