About the Author
Jeffry Houser is a technical entrepreneur that likes to share cool stuff with other people.
In the days before business met the Internet, Jeffry obtained a Computer Science
degree. He has solved a problem or two in his programming career. In 1999, Jeffry
started DotComIt; a company specializing in custom application development.
During the Y2K era, Jeffry wrote three books for Osborne McGraw-Hill. He is a
member of the Apache Flex Project, and created Flextras; a library of Open Source
Flex Components. Jeffry has spoken all over the US. He has produced hundreds of
podcasts, written over 30 articles, and written a slew of blog posts.
In 2014, Jeffry created Life After Flex; an AngularJS training course for Flex
Developers. In 2016, Jeffry launched the Learn With series with books focusing on
using AngularJS with other technologies. Jeffry has worked with multiple clients
building AngularJS applications.

I was a Flex developer for a long time; however, Adobe’s Flash Platform is no longer
relevant. A smart developer will spend time educating himself on new technologies
to keep up with a changing market, and to make sure he has healthy job prospects
in the future. While cultivating these new skills, I decided to write about my
experiences. With this series of books, you can leverage my experience to learn
This book is about my experiences building Angular applications. Angular is a
JavaScript framework built by Google for building smart user interfaces. It is built on
TypeScript and allows you to build dynamic views in HTML5. It is fully testable,
which is important to many enterprise-level applications. It has a large developer
community, ready to help with problems. I greatly enjoy building applications with
This book will show you how to build a Task Manager application using Angular and
Bootstrap. It uses REST services built with NodeJS, so Angular can interact with a
fully functional backend.

What is this Book Series About?
The purpose of this series is to teach by example. The plan is to build an application
using multiple technologies. These books will document the process, with each
book focusing on a specific technology or framework. This entry will focus on
Angular 4 as the application framework, and Bootstrap as the primary UI
component library.
The application built in this book will focus on common functionality required when
I build applications for enterprise consulting clients. You’ll receive step-by-step
instructions on how to build a task manager application. It will integrate with a
service layer. A login will be required. Functionality will be turned off or on based
on the user’s role. Data will be displayed in a DataGrid, because all my enterprise
clients love DataGrids. Common tasks will be implemented for creating, retrieving,
and updating data.

How to Read This Book
Each chapter of this book represents one aspect of the application’s user interface;
logging in, editing a task, etc. Each chapter is split up into these parts:
· Building the UI: This section will show you how to create the UI elements of
each chapter.
· The Database: There will be sections to review the data that each chapter’s
functionality deals with. The database storage tables will be examined here,
as well as an explanation of the data types.
· The Services: This section will cover the APIs of the services that need to be
interacted with. This book will help you create services using NodeJS. If you’re
feeling adventurous, you should be able to build out the services to any
language of your choice.
· Connecting the UI to the Services: This section will show you how the UI
code will call the services and handle the results.

Who Is This Book for?
Want to learn about building HTML5 applications? Are you interested in Angular or
Bootstrap? Do you want to learn new technologies by following detailed examples
with runnable code? If you answered yes to any of these questions, then this book
is for you!
Here are some topics we’ll touch on in this book, and what you should know before
· TypeScript: This is the language behind Angular. TypeScript is a statically
typed language that compiles to JavaScript. The more you know about it, the
better. If you are not familiar with it yet, check out our tutorial lesson on
learning the basics of TypeScript.
· NodeJS: We use these scripts to compile our TypeScript into JavaScript,
process CSS, and copy files. We’ll also use NodeJS to build rest services which
the main UI will integrate with. Familiarity with NodeJS will be beneficial, but
is not required.
· JavaScript: TypeScript compiles to JavaScript to run in the browser. Aside
from that, we touch on JavaScript routinely through the book in order to
configure NodeJS scripts, and SystemJS; a module loader used by Angular. You
should be familiar with JavaScript.
· Angular: The primary focus of this book is on Angular, so we are going
assuming you have no experience with it. At the time of this writing, the most
current version is Angular 4. If you’re looking for information on the AngularJS
1.x code base, check out some of the other books in this series.
· JSON: The data returned from the services will be done so as JSON packets.
JSON should be easy to understand, but if you have no experience with it,
check out our free introduction.
· Bootstrap: This is a CSS framework that helps create things such as popups
and date choosers. We’ll use it in conjunction with Angular to help flesh out
the application’s user interface.
· SQL: This is the database Server used as the storage mechanism for this
book. As such, the SQL language will be used to communicate with the
database from NodeJS. There aren’t any advanced SQL concepts in this book,
but you should have a general understanding of this type of database Server.
