Let's get into action and build a production-grade web application using JHipster. Before we start, we need a use case. We will be building an e-commerce web application that manages products, customers, and their orders and invoices. The web application will use a MySQL database for production and will have an Angular frontend. The UI for the actual shopping website will be different from the back office features, which will only be available for employees who have an administrator role. In this exercise, we will only be building a simple UI for the client-facing part. 

In this chapter, we will cover the following topics:

• How to create a monolithic web application using JHipster
• Important aspects of the code we've generated
• Security aspects of the application we've generated
• Run applications and tests
• Frontend screens we've generated
• Included tools that will ease further development
