Hands-On Swift 5 Microservices Development

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.

Writing the User Service

:Okay—let's start building the first service for our shop application! Everything should be set up at this point for you to start writing the services. What you learn in this chapter will equip you to build microservices within a bigger context. You will learn, step-by-step, what the code of a microservice looks like and how to interact with Vapor.

So far, we have been building up to this moment. You have learned the theory of how to build microservices and have prepared everything to get started. After you finish this chapter, you will be able to run your own, fully functional user manager service! It's the first microservice out of our example project and gives you a good idea of how to write your own user services. User services are very common across apps and websites, and the material of this chapter will hopefully help you with...
