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.

Vapor in Action

After you have installed Vapor and understand its basic principles, let's install the API template to get started. Run the following command:

$ vapor new FirstApp

This command is telling Vapor to download the most recent version of their API starter template. It's a preconfigured set of files that are a good starting point for API applications. Follow the given steps:

  1. Switch into the folder that contains FirstApp by typing the following:
$ cd FirstApp
  1. Now, let's create an Xcode project:
$ open Package.swift
  1. The preceding command will open the project for you automatically. You will now see the project and the structure you have learned about.
  2. To run a Vapor application in Xcode you must make sure that you are running the "Run" target. It might default to another one. To run correclty it should look like this:

That's all for...
