React + Django Full Stack E-Commerce Project #5 | Cart Functionality (Backend)

5 / 10

In this video (Part 5 of the Full Stack E-Commerce Project), we’ll build the Cart Functionality (Back-End) using Django REST Framework (DRF) and connect it with our React frontend.


You’ll learn how to create Cart and CartItem models, build REST API endpoints for adding, removing, and viewing cart items, and then use fetch() in React to synchronize the cart data in real-time.


This is a crucial part of the full-stack E-Commerce system where we connect backend logic with frontend actions.


📘 What You’ll Learn

-- Create Cart and CartItem models in Django

-- Build API endpoints:

/api/cart/ → View cart items

/api/cart/add/ → Add product to cart

/api/cart/remove/ → Remove item from cart

-- Create serializers for Cart and CartItem

-- Sync cart data using React fetch() API

-- Test backend endpoints in Thunder Client / Postman

-- Prepare for frontend cart UI in the next part
