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 and taking the first step

In this section, we will set up our environment. Everything that we need in terms of code and software will be prepared here.

For you to start writing this service, you will need to have the following pieces in place:

  • A blank folder for this service
  • A new Git repository available
  • The microservice template we worked on in the previous chapters

If you have not completed any of the previous steps to have all three elements ready, please go back and finish those first. Microservices can be complex, and if not organized well, will end up in a mess.

This section will cover the following:

  • Setting up the template
  • Installing SendGrid
  • Setting up JSON Web Tokens (JWT) and utility functions
  • Setting up the database
