Backend Challenge - Blog API

Introduction

The "Blog API" challenge is designed to build a RESTful API that allows users to manage blog posts, comments, and potentially user accounts.

Objectives

  • Set up a web server capable of handling API requests.
  • Implement endpoints for CRUD operations on blog posts and comments.
  • Handle user authentication and authorization (optional).
  • Understand HTTP methods (GET, POST, PUT, DELETE) and status codes.

Instructions

  1. Objective: Develop a RESTful API that provides functionality for managing blog posts and comments.

  2. Environment Setup: Choose your preferred programming language (e.g., JavaScript, Python, Java, C#) and set up the necessary environment.

  3. Implementation Details:

    • Define endpoints for blog posts (/posts) and comments (/posts/{postId}/comments):
      • GET /posts: Retrieve all blog posts.
      • POST /posts: Create a new blog post.
      • GET /posts/{postId}: Retrieve a specific blog post by ID.
      • PUT /posts/{postId}: Update an existing blog post.
      • DELETE /posts/{postId}: Delete a blog post.
      • GET /posts/{postId}/comments: Retrieve comments for a specific blog post.
      • POST /posts/{postId}/comments: Add a new comment to a blog post.
    • Implement logic to interact with blog post and comment data (e.g., store in database).
    • Optionally, implement user authentication and authorization for managing blog content.

  4. Testing: Test your API using a HTTP client (e.g., Postman, curl).

    • Send requests to each endpoint (/posts, /posts/{postId}/comments) with appropriate data payloads (e.g., JSON for creating/updating blog posts, comments).
    • Verify that the responses contain the expected data and that status codes are appropriate (e.g., 200 OK, 404 Not Found).

Possible Improvements

  • Pagination: Implement pagination for listing blog posts and comments.
  • Validation: Validate input data to ensure blog posts and comments meet expected criteria (e.g., required fields).
  • Error Handling: Enhance error messages and responses for invalid requests.
  • Security: Secure API endpoints, especially those involving user authentication and authorization.
  • Performance: Optimize database queries and API responses for better performance.

Conclusion

By completing this challenge, you will gain practical experience in developing a Blog API and learn essential practices for backend development. Explore additional improvements and challenges to further enhance your skills.

Happy coding!
