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.

Getting Started with the Vapor Framework

After learning about microservices and Swift, it is now time to focus on the framework you will use. Choosing the right framework is an integral part of our stack. After Swift was open-sourced, a couple of frameworks emerged as solid choices for web development. In this chapter, you will explore the Vapor framework and why it was chosen for this book over other frameworks.

At first, we will look at the Vapor framework and why it stands out. We will explore the features Vapor offers and look at some code examples. Afterward, we will learn how other frameworks compare to Vapor.

The chapter is structured as follows:

  • The Vapor framework
  • Comparing Vapor to Kitura, Perfect, and Smoke
  • Installing Vapor
  • Vapor in action
