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.

Creating our routes

Like the other services, our OMS needs to be callable publicly. We do that by setting up routes that allow the user, and other services, to call this service. The routes we set up in this section will do this for us.

This service does most of its work behind the scenes and not publicly. For the end user (or consumer), the following two actions are important:

  • Submit a new order.
  • Retrieve the history of orders.

For an administrator, we need to do the following:

  • Get the list of all orders
  • Add payment to an order

The following table list the orders:

strong>Path strong>Parameters Output/Description
/*/orders (Auth required) POST Expected Total Order Items Submits an order from an end-user/consumer
/*/orders (Auth required) GET - Returns all orders of the user from the JWT
/*/orders (Auth required, admin level) GET - Returns all users
/*/orders...
