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.

Planning an Online Store Application

By now, you have learned about microservices in general and server-side Swift and Vapor. Now it is time to put all of that into practice and start building our example project. You are going to develop the backend for an e-commerce application. Let's pretend you have already made an iOS app that serves as the frontend, but you have not built the backend for it yet. In this chapter, you are going to plan the server application for your store. You may have worked on several backends before; you may have never touched a backend in your life. This chapter will catch you up, and you will come up with a concrete plan.

A programmer saying goes that you should spend 90% planning and 10% writing code. While reality does not always hold up to this, it is essential to plan well. By the end of this chapter, you should be able to set everything up...
