Harshil Chovatiya - Day 57: Working with Web APIs

Brief: Web APIs serve as the backbone of modern web development, allowing applications to interact with external services and retrieve or send data. Today, we'll delve into the practical aspects of working with Web APIs, exploring various types and implementing them in a project. Get ready to make your first API requests and integrate data into your applications.

Introduction to API Requests:

Understand the basics of making HTTP requests to interact with Web APIs. Explore common HTTP methods like GET, POST, PUT, and DELETE.

                    
                    
    // Making a simple GET request using Fetch API
    fetch('https://api.example.com/data')
      .then(response => response.json())
      .then(data => console.log(data));
                    
                

Exploring Different Types of Web APIs:

Dive into various types of Web APIs, including RESTful APIs, SOAP APIs, and GraphQL. Compare their structures, use cases, and when to choose one over the other.

                    
                    
    // Example GraphQL query
    const query = `
     {
       user(id: 123) {
         name
         email
       }
     }
    `;
                    
                

Building a Project with a Web API:

Implement a project that utilizes a specific Web API. Understand the authentication process and handle API responses.

                    
                    
    // Example project using GitHub API
    const apiUrl = 'https://api.github.com/users/octocat';
    fetch(apiUrl)
      .then(response => response.json())
      .then(user => console.log(`Username: ${user.login}, Followers: ${user.followers}`));
                    
                

Handling Errors and Edge Cases:

Learn to handle errors that may occur during API requests. Explore techniques for managing edge cases and unexpected scenarios.

                    
                    
    // Handling errors in Fetch API
    fetch('https://api.example.com/data')
      .then(response => {
        if (!response.ok) {
          throw new Error('Network response was not ok');
        }
        return response.json();
      })
      .then(data => console.log(data))
      .catch(error => console.error('Error:', error));
                    
                

Code Optimization and Best Practices:

Explore best practices for optimizing code when working with Web APIs. Consider aspects such as asynchronous programming and data caching.

                    
                    
    // Using async/await for asynchronous API requests
    async function fetchData() {
      try {
        const response = await fetch('https://api.example.com/data');
        const data = await response.json();
        console.log(data);
      } catch (error) {
        console.error('Error:', error);
      }
    }
                    
                

Conclusion:
