In the cloud age, web technologies are more important than ever. The vibe.d framework enables you to use the D programming language for a wide range of web-related tasks. The D programming language allows elegant solutions for common problems, while native compilation produces fast binaries. The vibe.d framework takes advantage of these language features. Together with the innovative use of fibers, the applications that you build are scalable and have a very quick response time.
This book will explain everything you need to know about the vibe.d framework in order to successfully build and run web applications.
Chapter 1, Getting Started with Your First Web Application, explains how to set up and use your development environment. At the end of this chapter, you will have already created your first web application.
Chapter 2, Using Templates for Your Web Pages, covers the Diet template engine. You will learn all about templates—from creating simple static templates to using D code in templates.
Chapter 3, Get Interactive – Forms and Flow Control, brings web forms to your application and introduces route matching.
Chapter 4, Easy Forms with the Web Framework, discusses how to validate user input.
Chapter 5, Accessing a Database, shows how to use a database in an application using a variety of SQL and NoSQL bases.
Chapter 6, Using the REST Interface, teaches you about REST services. You will learn how to provide and consume a generated REST service. You will also study how to interface with an existing REST service.
Chapter 7, The vibe.d Internals, introduces you to the fiber-based pseudo-blocking programming model that is the base for vibe.d.
Chapter 8, Using vibe.d with a GUI Client, applies the vibe.d programming model to a graphical UI application.
Chapter 9, Power Your Application with vibe.d Extensions, shows you what other developers have already implemented with vibe.d and how to publish your application.
You need a Linux, Windows, or Mac PC that is capable of running the DMD D compiler and the DUB package manager. Both software packages are available at http://code.dlang.org/. The vibe.d framework requires an SSL library and the libevent library to be installed. The various sources are described in Chapter 1, Getting Started with Your First Web Application.
In order to compile the examples, you need an Internet connection in order to allow the automatic download of dependent software.
For the example in Chapter 5, Accessing a Database, you need Redis 3.x (available at http://redis.io/), MongoDB 3.x (available at http://ww.mongodb.org/), and MySQL 5.x (available at http://dev.mysql.com/downloads/). Chapter 6, Using the REST Interface, uses CouchDB (available at http://couchdb.apache.org/) and Chapter 9, Power Your Application with vibe.d Extensions, uses Cassandra (available at http://cassandra.apache.org/).
Whether you are new to the world of D, already have developed applications in D, or you want to leverage the power of D for web development, then this book is ideal for you. Basic knowledge of core web technologies, such as HTML 5, is helpful; however, it not necessary. This book explains the complex details to speed your web development.
In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "You also need to install openssl and libevent, which are used by vibe.d."
A block of code is set as follows:
name "hello" description "A simple vibe.d server application." copyright "Copyright © 2015, <yourid>" authors "<yourid>" dependency "vibe-d" version="~>0.7.23" versions "VibeDefaultMain"
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
body
block header
header Header
block navigation
include navigation
block content
block footer
footer FooterAny command-line input or output is written as follows:
$ tar xvzf dub-0.9.24.tar.gz $ cd dub-0.9.24 $ ./build.sh
New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Click on the Unlock button to unlock the window and change the account type to Administrator."
