In this series of posts we will create an application using react and redux, in which we will handle relational data. In this first part we will be modelling the store.

In Event-driven architecture there are unique identifiers everywhere: at entity level, at event level, at process level etc. In this blog post, I will show you a de facto standard for how you could easily generate, persist, serialize and deserialize IDs natively through Kafka, Java and JPA.

To test WebClient code, we need a different setup than for RestTemplate based clients. In WebFlux applications the use of the OkHttp MockWebServer is recommended.

Testing pessimistic locking handling in JPA is tricky because of the lack of JPA support of LockTimeout by different RDBMS providers. Yet leaving a critical part of the code untested is against the software craftsmanship's principles. In this blog post, I will show you through the medium of 3 GitHub projects how you could test it within Spring Boot Application against Oracle, MySQL and PostgreSQL.

Even though Angular has multiple core technologies which improve with no-effort how our bundle is generated, it's not strange size becomes a problem that require some sort of special caring. In this post we are going to analyze basic tips that ultimately lead to a lighter and snappier Angular application.
