Section 3: Practical Application of Design Patterns

In this section, you will apply your new knowledge of design patterns to implement a real-world application and learn some best practices and anti-patterns.

The section starts with a collection of best practices and things to avoid while developing applications using Kotlin. Then, in the following two chapters, we will build two microservices, first using a concurrent framework called Ktor, and in the last chapter using a reactive framework called Vert.x.

We'll also use this opportunity to examine how design patterns we've seen in the previous chapters come into play in real-world applications.

This section comprises the following chapters:

• Chapter 9, Idioms and Anti-Patterns
• Chapter 10, Concurrent Microservices with Ktor
• Chapter 11, Reactive Microservices with Vert.x
