Backend Challenge - Basic E-commerce API

Introduction

The "Basic E-commerce API" challenge is designed to build a RESTful API that allows basic management of products, orders, and potentially user accounts.

Objectives

  • Set up a web server capable of handling API requests.
  • Implement endpoints for CRUD operations on products and orders.
  • 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 products and orders in an e-commerce system.

  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 products (/products) and orders (/orders):
      • GET /products: Retrieve all products.
      • POST /products: Create a new product.
      • GET /products/{productId}: Retrieve a specific product by ID.
      • PUT /products/{productId}: Update an existing product.
      • DELETE /products/{productId}: Delete a product.
      • GET /orders: Retrieve all orders.
      • POST /orders: Create a new order.
      • GET /orders/{orderId}: Retrieve a specific order by ID.
      • PUT /orders/{orderId}: Update an existing order (e.g., change status).
      • DELETE /orders/{orderId}: Cancel an order.
    • Implement logic to interact with product and order data (e.g., store in database).
    • Optionally, implement user authentication and authorization for managing orders.

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

    • Send requests to each endpoint (/products, /orders) with appropriate data payloads (e.g., JSON for creating/updating products, orders).
    • 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., required fields, product pricing).
  • 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, especially under high load.
  • Payment Integration: Integrate with a payment gateway for processing orders.

Conclusion

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

Happy coding!
