Backend Challenge - User Profile API

Introduction

The "User Profile API" challenge is designed to build a REST API that allows basic management of user profiles, including creation, retrieval, updating, and deletion.

Objectives

  • Set up a web server capable of handling API requests.
  • Implement endpoints for CRUD operations on user profiles.
  • Store user profile data (e.g., username, email, bio) persistently.
  • Understand HTTP methods (GET, POST, PUT, DELETE) and status codes.

Instructions

  1. Objective: Develop a REST API that provides functionality for managing user profiles.

  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 user profiles (/profiles):
      • GET /profiles: Retrieve all user profiles.
      • POST /profiles: Create a new user profile.
      • GET /profiles/{userId}: Retrieve a specific user profile by ID.
      • PUT /profiles/{userId}: Update an existing user profile.
      • DELETE /profiles/{userId}: Delete a user profile.
    • Implement logic to interact with user profile data (e.g., store in database).
    • Handle basic fields such as username, email, and bio for each user profile.

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

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

Possible Improvements

  • Validation: Implement validation for input data (e.g., email format, required fields).
  • Error Handling: Enhance error messages and responses for invalid requests.
  • Security: Consider security measures such as input sanitization and preventing SQL injection.
  • Pagination: Implement pagination for listing user profiles, especially if the number of profiles grows.
  • Performance: Optimize database queries and API responses for better performance.

Conclusion

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

Happy coding!
