Hands-On Swift 5 Microservices Development

By: Ralph Kuepper

Overview of this book

The capabilities of the Swift programming language are extended to server-side development using popular frameworks such as Vapor. This enables Swift programmers to implement the microservices approach to design scalable and easy-to-maintain architecture for iOS, macOS, iPadOS, and watchOS applications. This book is a complete guide to building microservices for iOS applications. You’ll start by examining Swift and Vapor as backend technologies and compare them to their alternatives. The book then covers the concept of microservices to help you get started with developing your first microservice. Throughout this book, you’ll work on a case study of writing an e-commerce backend as a microservice application. You’ll understand each microservice as it is broken down into details and written out as code throughout the book. You’ll also become familiar with various aspects of server-side development such as scalability, database options, and information flow for microservices that are unwrapped in the process. As you advance, you’ll get to grips with microservices testing and see how it is different from testing a monolith application. Along the way, you’ll explore tools such as Docker, Postman, and Amazon Web Services. By the end of the book, you’ll be able to build a ready-to-deploy application that can be used as a base for future applications.

Creating Your First Microservice

You made it! The theoretical part is mostly done, and we are now talking code! In this chapter, you will write your first microservice. However, before we write it, you will be introduced to the practical parts of a Vapor application. Using the Vapor framework will help you to write apps faster than if you were to start from scratch. By the end of this chapter, you will have written your first microservice and incorporated the necessary pieces.

In this chapter, you will learn how to develop a generic microservice that will serve as the basis for our online shop backend application. This will also be the basis for all the other services that we will write throughout this book. We will develop a template that will be used to create other services and that you could use for your own projects as well. By the end of this chapter, you will have written...
