Backend Challenge - Forum API

Introduction

The "Forum API" challenge is designed to build a RESTful API that allows management of forums, threads, posts, and potentially user accounts.

Objectives

  • Set up a web server capable of handling API requests.
  • Implement endpoints for CRUD operations on forums, threads, and posts.
  • 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 forums, threads, and posts.

  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 forums (/forums), threads (/forums/{forumId}/threads), and posts (/threads/{threadId}/posts):
      • GET /forums: Retrieve all forums.
      • POST /forums: Create a new forum.
      • GET /forums/{forumId}: Retrieve details about a specific forum.
      • PUT /forums/{forumId}: Update an existing forum.
      • DELETE /forums/{forumId}: Delete a forum.
      • GET /forums/{forumId}/threads: Retrieve all threads in a forum.
      • POST /forums/{forumId}/threads: Create a new thread in a forum.
      • GET /threads/{threadId}: Retrieve details about a specific thread.
      • PUT /threads/{threadId}: Update an existing thread.
      • DELETE /threads/{threadId}: Delete a thread.
      • GET /threads/{threadId}/posts: Retrieve all posts in a thread.
      • POST /threads/{threadId}/posts: Create a new post in a thread.
      • GET /posts/{postId}: Retrieve details about a specific post.
      • PUT /posts/{postId}: Update an existing post.
      • DELETE /posts/{postId}: Delete a post.
    • Implement logic to interact with forum, thread, and post data (e.g., store in database).
    • Include fields such as forum title, thread subject, post content, and user associations.

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

    • Send requests to each endpoint (/forums, /forums/{forumId}/threads, /threads/{threadId}/posts) with appropriate data payloads (e.g., JSON for creating/updating forums, threads, posts).
    • 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 forums, threads, and posts.
  • Error Handling: Enhance error messages and responses for invalid requests or when data is not found.
  • Authentication: Secure API endpoints, especially those involving user operations like creating, updating, or deleting forums, threads, or posts.
  • Search Functionality: Implement search functionality to allow users to search for forums, threads, or posts by title or content.
  • Notifications: Add support for notifications when new posts are added to subscribed threads.

Conclusion

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

Happy coding!
