Features

This project is a comprehensive, full-featured e-commerce solution designed for small to mid-sized businesses looking to establish or scale their online presence. The system focuses on ease of management for individual sellers and small teams, with a clear distinction between administrative and user functionalities. The platform is built to ensure high maintainability, scalability, and robust performance, all while maintaining a smooth user experience. Note: Product and category creation and management are restricted to administrators, making this platform ideal for businesses where a central admin oversees the product catalog.

1. Unfold Admin with Custom Dashboard

The application leverages the powerful django-unfold package to deliver an intuitive and data-rich admin dashboard. This custom dashboard is designed to give administrators quick and actionable insights into business performance:

Product Sales Chart: Visualizes sales data to show how individual products are performing.
Monthly Revenue Chart: Provides a comprehensive view of monthly earnings, helping administrators track revenue trends over time.
Order Performance Chart: Displays the total number of orders and highlights changes in order volumes to help gauge customer activity.
Top 3 Best-Selling Products Cards: Highlights the three best-performing products, giving a quick glance at what's driving sales.
New Customers Data Card: Summarizes recent customer sign-ups, offering insights into the growing customer base.
New Products Data Card: Displays data on recently added products, keeping administrators informed of new inventory.
New Categories Data Card: Provides a summary of new product categories, giving an overview of catalog diversification.

2. Custom JWT Authentication with Cookie-Based Storage

Implements a secure authentication mechanism using JWT, with access and refresh tokens stored in secure HTTP-only cookies. This approach combines the stateless benefits of token-based authentication with enhanced security practices for user session management.

3. Consistent and Customizable API Responses

All API endpoints return standardized response formats with custom helper functions for handling both successful and error states. This ensures uniformity across the entire platform, simplifies error management, and enhances the user experience on the front-end by providing clear feedback.

4. Cloudinary for Media Storage

Utilizes Cloudinary for all media storage, ensuring fast and reliable hosting of images and media assets. Cloudinary\u2019s built-in transformation tools allow for automatic optimization of media, improving page load times and overall performance.

5. Integrated Payment Systems: Razorpay and Cash on Delivery (COD)

The application integrates Razorpay for seamless online payments, enabling secure transactions between customers and the platform. Additionally, a Cash on Delivery (COD) option is available, allowing for greater flexibility and accessibility for users who prefer offline payment methods.

6. Advanced Product Review System

Enables users to leave reviews for products they have purchased, improving customer engagement and providing valuable feedback to store owners. Administrators maintain full control over reviews, allowing for easy moderation to ensure only relevant and appropriate content is displayed.

7. Custom Pagination for All List Views

All list-based views are paginated using a custom class designed for flexibility. It supports customizable page sizes and default sorting by the created_at field, ensuring recent entries are always surfaced first.

8. Comprehensive Cart and Order Management

Offers a full suite of cart and order management features, including adding, updating, and removing items from the cart. The cart logic ensures that the same product cannot be added multiple times, even by administrators.
Orders are fully manageable, with the ability to update only the shipping address post-purchase, cancel, or return orders, ensuring users have the flexibility to manage their purchases.

9. Admin-Only Product and Category Management

Products and categories can only be created, updated, or deleted by administrators. This centralized management approach is perfect for small businesses or individual sellers who need full control over their product catalog and inventory.
Users can view and purchase products, but they cannot modify the product catalog, or become a seller on the platform.

10. Whitenoise for Static Files Management

The application uses Whitenoise to serve static files in production environments, reducing server load and improving the overall performance of the website. This ensures that assets such as stylesheets and JavaScript files are delivered quickly and efficiently to users.

11. Error Handling and Validation

Features robust error handling throughout the application, providing meaningful feedback for both successful and erroneous operations. This ensures smooth functionality and enhances the user experience by catching and resolving issues promptly.

12. Use of ViewSets for Maintainability

The project takes advantage of Django REST Framework\u2019s ViewSets, which provide a structured and maintainable way to handle API endpoints. ViewSets minimize code redundancy by automatically routing requests to the appropriate view methods based on HTTP methods, making it easier to scale and extend the application.
