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.

Using workers

A worker is a class or struct that performs tasks for us; it is usually a bit more complicated than what a controller would do. Examples of this include converting images, processing orders, and working through batches. In traditional server setups, you would do the same through cron jobs.

Depending on the nature of what your workers will do, you could wrap their functionality into a job with the vapor/jobs package. That way, you have automatic retries already given. You can check out the package here: https://github.com/vapor/jobs

And that's it our template is ready! You can find the full working template in the GitHub repository for this chapter!
