Workshop
In this advanced intensive training, you will learn how modern backends can be developed for an Angular application. During the training, in addition to developing the backend, you will also develop the logic required for communication with the backend within the Angular application yourself.
You will learn how to decompose your backend into microservices using Domain-driven Design. You will find out what good communication via HTTP is and what REST is really all about.
But topics such as data access, authentication, and authorization are also examined in more detail during the training.
The exercises included in the training thus create a backend with Angular application, which you can use later as a template for your own applications.


Highlights
✅ Interactive: Ask questions and participate in discussions
✅ Lots of exercises and live coding
✅ Case study to use as a blueprint for your own projects
✅ Pair programming with your trainer

Microservices with Spring Boot
Using a case study, we develop a Spring Boot backend for an Angular client.
We get to know Domain-driven Design as a foundation for a microservice architecture. Our goal is to develop a functional and expandable application right at the beginning of the training, which we can expand as the training progresses.
We assume that you already have experience with Java.
The following aspects are examined in detail:
- Design of a microservice architecture using Domain Driven Design
- Use HTTP and its functions correctly
- Design of good REST services using Spring and Routing
- Describe your API using Swagger/ OpenAPI
- Logging, startup and configuration
Data Access with Spring Data and JPA/ Hibernate
Almost every application works with data and has to persist it. In this part, we extend our application with a relational database that we access using Spring Data and JPA/ Hibernate.
The following aspects are examined in detail:
- Database access using Spring Data, JPA/ Hibernate
- Data Transfer Objects and POCOs
- Mapping relationships
- Change tracking in distributed systems
Authentication and Authorization with Spring Security
Another common application requirement is the ability to identify who is using the
Application and whether they are allowed to work with the requested data/functions.
Therefore, in the next step, we will add authentication and authorization to our application. We learn how an existing user database can be connected, but also how we can create our own user directory just for our application.
The following aspects are examined in detail:
- OAuth2 and OpenId Connect as modern authentication protocols
- JSON Web Tokens (JWT) as container for OAuth2 and OpenId Connect information
- Redhat Keycloak
- Integration of your own Security Token Service
Advanced Topics
We spend the rest of the time with your specific questions and further topics. Examples are:
- Working with binary data and streaming
- Asynchronous communication via message queues
- Use of own data formats beyond XML and JSON
- Integration of document-oriented databases such as MongoDB or ComosDB
- Service Discovery and Load Balancing
- Hosting with Docker
