Problem

The client required a scalable backend API for an E-commerce shopping list application that would handle complex user interactions with shopping lists and items. Key requirements included:

• Efficient Data Management: The API needed to accommodate a growing number of users and items while ensuring quick data retrieval.

• Security and Access Control: A robust permission system to ensure users only accessed and modified their own shopping lists.

• Reliability and Scalability: An architecture that allowed easy future enhancements and high reliability, verified through comprehensive testing.

Solution

We built a RESTful Shopping List API using Django and Django REST Framework (DRF), with a focus on modular architecture and maintainability:

• Core Architecture: The core directory handled essential project settings, centralized routing, and middleware integration.

• Modular App Design:

  • shopping_list app: Contained all business logic, including models for lists and items, with well-defined relationships.

  • API Layer:

    • Views and URLs handled user interactions, executing CRUD operations.

    • Serializers enabled seamless data transformation between models and JSON, ensuring consistent and validated data.

    • Permissions controlled access to ensure user security and restricted operations to authorized actions.

    • Custom Pagination improved data retrieval, enabling efficient browsing of large datasets.

• Test-Driven Development:

  • We implemented Pytest for unit, integration and end-2-end (E2E) tests, ensuring full coverage of CRUD operations, permissions, and API interactions.

  • Thorough testing assured reliability, scalability, and prevented regressions.

• Security: Implemented token-based authentication, securing user sessions and preventing unauthorized access.
