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.

Understanding project setup and folder structure

Let's start by setting up the folders for our project. It is important for a microservice project to have a clean folder setup to keep everything organized. We will need folders for the following microservices:

  • OrderService: Our order processing service, which processes the payment and saves the order
  • ProductService: Our product service that delivers the product information
  • UserService: Our user service that manages user accounts

Follow the steps given here:

  1. Create a new folder for the project and name it Shop Backend. You can put this folder anywhere on your computer. You want to keep everything organized in one central place on your development machine.
  1. Create a template folder and move the code of the template we created in Chapter 5, Creating Your First Microservice into it.
  2. Create three empty folders called OrderService...
