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.

Setting Up Routes and Controllers

This chapter dives into the details of handling custom requests with routes and controllers. A route in a web framework is an object used to represent a custom request embedded in a URL, and a controller is the component that contains the business logic to handle the request routed to it. You'll learn how to add custom routes for requests, create controllers to handle the routes, and construct responses for the requests. You'll manipulate custom parameter types and process a group of routes in a collection. Finally, you'll learn how to take advantage of the Codable an class in Swift to encode and decode complex JavaScript Object Notation (JSON) objects in easy way.

Let's take a look at the topics covered in this chapter:

  • Adding custom routes in a Vapor project
  • Adding custom routes in a Kitura project
