Front End Integration Case Studies

The purpose of this lesson is to explore various case studies in front-end integration, focusing on how different applications utilize APIs to enhance user experience and functionality. Understanding these integrations can significantly improve your front-end architecture design.

Overview

This case study focuses on an e-commerce platform that integrates with a payment gateway and a product inventory API.

Integration Steps

1. Define API endpoints for product listings and payment processing.
2. Use fetch to get product data from the inventory API.
3. Implement a checkout process using the payment gateway API.

Code Example

const fetchProducts = async () => {
    const response = await fetch('https://api.example.com/products');
    const products = await response.json();
    displayProducts(products);
};

const processPayment = async (paymentData) => {
    const response = await fetch('https://api.example.com/pay', {
        method: 'POST',
        body: JSON.stringify(paymentData),
        headers: {
            'Content-Type': 'application/json',
        },
    });
    return response.ok;
};

Overview

This case study explores how a news website integrates with social media APIs for content sharing and user engagement.

Integration Steps

1. Authenticate with the social media API using OAuth.
2. Fetch user data and posts to display on the website.
3. Implement sharing features for articles using the social media API.

Code Example

const authenticateWithSocialMedia = async () => {
    const authUrl = 'https://socialmedia.com/oauth/authorize';
    window.location.href = authUrl;
};

const fetchUserPosts = async (accessToken) => {
    const response = await fetch('https://api.socialmedia.com/user/posts', {
        headers: {
            'Authorization': `Bearer ${accessToken}`,
        },
    });
    const posts = await response.json();
    displayUserPosts(posts);
};

Key Takeaways

• Always handle errors gracefully when dealing with external APIs.
• Implement caching strategies to reduce API calls and enhance performance.
• Regularly review and update API integrations to stay compliant with changes.
