Hands-On Server-Side Web Development with Swift

Getting Started with Vapor and Kitura

This chapter aims at getting you started with both Vapor and Kitura. You'll be introduced to Vapor Toolbox, a command-line interface (CLI), which allows you to rapidly develop Vapor apps from several boilerplate Vapor projects. You'll follow a step-by-step guideline to install Vapor Toolbox on macOS or Linux, and then check your system's readiness by using Vapor CLI tools to verify system compatibility with the required development environment. Similarly, you'll get introduced to the Kitura development environment and follow step-by-step instructions to install Kitura tools and libraries on your system.

In this chapter, we'll cover the following topics:

  • Installing Vapor and Kitura on macOS
  • Installing Vapor and Kitura on Ubuntu
  • Exploring Vapor Toolbox and the Kitura CLI
...

Installing Vapor and Kitura on Mac

Even though you can start server-side Swift development on either macOS or Linux, you'll find it more convenient to develop server-side Swift projects on macOS with Apple's free Integrated Development Environment (IDE) tool, Xcode. Xcode has integrated many powerful editing and debugging features to streamline the workflow for code development with Swift; for example, syntax highlight, auto completion, refactoring, and code coverage for unit tests.

Follow the steps in the following sections to prepare your Mac for server-side Swift development with both Vapor 3.0 and Kitura 2.5. Skip the installation steps for macOS and go directly to the next section if you want to use the Linux environment instead.

Preparing your Mac for server-side Swift...

Installing Vapor and Kitura on Ubuntu

This section is for installing Vapor and Kitura on Ubuntu. Skip this section if you intend to develop on your Mac only.

Working with the Ubuntu APT

You're going to work with the Advanced Packaging Tool (APT) library to perform installation of Vapor and Kitura. APT is a package manager for Debian-based Linux operating systems such as Ubuntu. The package manager keeps a list of packages that it can install in repository or cache and sorts out the dependencies required for the software packages. Run the following at Command Prompt:

$ sudo apt-get install <package>

The apt-get install command checks for the repository for the package specified as <package>. If the package...

Exploring Vapor Toolbox and the Kitura CLI

Vapor Toolbox and the Kitura CLI are provided to make your life easy with extensive command-line tools and to accelerate your server-side Swift project development effort with many useful boilerplate projects. Since Vapor and Kitura projects are built with Swift Toolchains, you also have access to an array of tools in Swift Package Manager (SPM), the standard software package manager for managing the distribution of Swift projects.

SPM includes the following handy commands:

Useful CLI Commands Usage
swift build Compiles the package in the current directory
swift run Runs the executable in this package (for only one executable in the package)
swift run Runs the executable in this package
swift package resolve Resolves the dependencies and download missing packages
swift package xcode-generateproj Creates an Xcode project...

Exploring the Kitura CLI

Most of the CLI features in Kitura are encompassed in Kitura Application Generator (KAG), which allows you to configure a new Kitura project in a question and answer way. If you just need a basic starter project, you can simply use the kitura init command:

Useful CLI Commands Usage
kitura init Creates a basic starter project
kitura create Creates an application using KAG

The rest of this section will cover the usage of KAG.

Using KAG

The kitura create command will launch Kitura's powerful application generator. If you don't want to customize the boilerplate for your Kitura project, you can simply skip this tool and use kitura init to create a basic starter project.

Once you...

Summary

In this chapter, you've been provided with step-by-step instructions on how to install both Vapor Toolbox and the Kitura CLI on Mac or Linux. Whether Mac or Linux, your system is now ready for some serious server-side Swift project development. You've also learned the usage of some of the most useful command-line tools offered by the Swift Package Manager, Vapor Toolbox, and the Kitura CLI. In the next chapter, you're going to explore these tools to develop your first web applications using the Vapor and Kitura frameworks.

Description

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.

Who is this book for?

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.
