2. E-Commerce - Shopping Cart

In this project, you will build an e-commerce application using Java, JHipster, Spring Boot, and React.

This project focuses on building a shopping cart and payment integration rather than how to build a Java web application.

Project overview: Build a persistent shopping cart page where you can list all the items added to the cart by the user. The user can also start checkout from this page. The shopping cart will hold the items added until the payment is complete, even if the user logs out or uses the application on a different machine, as the state is persisted automatically using the generated CRUD API.

Here is the screenshot of this demo application:

3. BookStoreApp-Distributed-Application

This e-commerce project is being developed using Spring Boot Microservices, Spring Cloud (Backend), and React (Frontend). The e-commerce functionality is being split into various individual microservices so that they can be distributed, scale well, and use resources efficiently.

This is an E-commerce project where users can add books to their cart and buy them.

The application is being developed using Java, Spring, and React.

Using Spring Cloud Microservices and Spring Boot Framework extensively to make this application distributed.

Architecture

All the Microservices are developed using Spring Boot. This Spring Boot application will be registered with the Eureka discovery server.

FrontEnd React App makes requests to the NGINX server, which acts as a reverse proxy. NGINX server redirects the requests to the Zuul API Gateway.

Zuul will route the requests to microservices based on the URL route. While routing the request, Zuul also registers with Eureka and gets the IP/domain from Eureka for microservices.
