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.

Creating an app using Kitura CLI

After your first Hello World application in Vapor, let's do the same using Kitura CLI to create a similar Hello World application in Kitura.

Creating a hello world app from a default template

  1. First, create a new directory called helloWorld and change the directory to helloWorld:
# Step 1a: Create a new directory for your project
$ mkdir helloWorld
$ cd helloWorld

Kitura CLI will use the current directory's name to create your project and put all the files in the same directory.

  1. Next, use the kitura init command to create a new project from the default Kitura template:
# Step 1b: Create helloWorld app using the default Kitura template
$ kitura init

This step not only creates...
