The book covers topics related to creating an end-to-end modern web application by using Angular for building the web app frontend and Spring framework for the backend, while integrating the apps via REST APIs and securing the API transactions using Spring Security concepts. Traditionally, Java developers have been used to developing the backend of a web application, while the frontend (UI) has been left for UI developers. However, this book aims to enable and empower Spring web application developers to quickly get started with Angular and build frontend (UI) components as well along with the backend components.

The following are some of the key challenges that we will address in this book:

• Building Angular apps (especially for Spring web developers)
• Security
• Integration
• Deployment

Here are some of the key milestones that we will cover in this book:

• Preparing development environments, where we highlight the usage of Docker containers to create a development environment that is easy to spin up and decommission once done
• Creating Spring Boot web application backend components such as API endpoints, controllers, services, and data access components using the Spring Web MVC framework and Hibernate
• Creating web application frontend (UI) or rather single-page apps (SPAs) using Angular concepts such as Components, Services, Routing, and so on
• Unit testing both Spring and Angular apps
• Building and running both Spring and Angular apps
• Securing the API transactions using Spring security and also taking care of security aspects related to the content displayed on the frontend (Angular apps)
• Integrating Angular apps with Spring Web app REST endpoints
• Deploying web apps based on Continuous Delivery principles
