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.

Setting up Vapor and the database

At this point, Swift and Vapor are already installed and functional for you. If not, go back to Chapter 3. What's left to do is set up your local database environment. Since we are already using Docker, you can easily spin up a MySQL database through Docker. Follow the given steps:

  1. Go into your terminal and run the following commands:
sudo mkdir /usr/local/opt/mysql
sudo mkdir /usr/local/opt/mysql/8.0
sudo chmod -R ug+w /usr/local/opt/mysql/

By executing the preceding commands, we are installing a local database folder that the Docker instance can access. It keeps us from losing our data when we close Docker.

  1. Now, grant Docker permission to share information with that folder. Open the preferences for Docker:
  1. Add the folder we just created to the files under File Sharing and press Apply & Restart:
  1. Now, we can start our MySQL server...
