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.

Application Structure and Database Design

After you created your own template for your services, let's now set up the entire project. This chapter will set you up practically so you can work on the backend structure. For a microservice application that involves running multiple applications (on each service) all at once, the setup is vastly different from monolithic development: in a monolithic application, you can test it all by just testing one application. In a microservice setup, you need to test multiple microservices interacting with each other.

The essence of this chapter is to get your system ready for microservice development. You will learn how an application should be structured and how to design your database. We will get really practical in this chapter and set up the folders we need for the chapters to come. You will also learn how to set up Git and Docker,...
