Hands-On Server-Side Web Development with Swift

By: Angus Yeung

Overview of this book

This book is about building professional web applications and web services using Swift 4.0 and leveraging two popular Swift web frameworks: Vapor 3.0 and Kitura 2.5. In the first part of this book, we’ll focus on the creation of basic web applications from Vapor and Kitura boilerplate projects. As the web apps start out simple, more useful techniques, such as unit test development, debugging, logging, and the build and release process, will be introduced to readers. In the second part, we’ll learn different aspects of web application development with server-side Swift, including setting up routes and controllers to process custom client requests, working with template engines such as Leaf and Stencil to create dynamic web content, beautifying the content with Bootstrap, managing user access with authentication framework, and leveraging the Object Relational Mapping (ORM) abstraction layer (Vapor’s Fluent and Kitura’s Kuery) to perform database operations. Finally, in the third part, we’ll develop web services in Swift and build our API Gateway, microservices and database backend in a three-tier architecture design. Readers will learn how to design RESTful APIs, work with asynchronous processes, and leverage container technology such as Docker in deploying microservices to cloud hosting services such as Vapor Cloud and IBM Cloud.

Debugging and Testing

A seasonal developer spends far more time on debugging and testing code than writing code, in a typical software project. This chapter introduces the basics of writing tests for a server-side Swift project and recommends the best practice in debugging server-side Swift code. When it comes to a web development framework, both the Vapor and Kitura frameworks offer very good testing and debugging support. You are going to learn how to use the test framework in Swift and logging features in Vapor and Kitura to help debugging and error-proofing your code.

This chapter covers writing tests for server-side Swift projects as well as debugging in server-side Swift.

The following is a list of topics on debugging for server-side Swift:

  • Using the Logging API in a Vapor project
  • Using the Logger API in a Kitura project
  • Debugging using the HTTP traffic monitoring tool...
