preface

Never in my wildest dreams did I think that I would be an author, and yet here I am. I

vividly remember the panic that I felt as I clicked “Publish” on my first WordPress post

on AngularJS. It felt like I was pressing the launch button for a series of missiles, and I

had no idea where they would go! Little did I know that I had in fact released a series

of missiles that would change my life in the most profound and unexpected ways.

The moment I decided that I cared more about being helpful than being perfect

was one of the most important turning points of my life. Beginning with a series of

barely passable blog posts, by accepting every opportunity to implement feedback I

gradually grasped what it takes to write a solid blog post. It was also during that time

that I had the opportunity to become friends with the AngularJS core team. AngularJS

at the time was still relatively unknown, and so it was much easier to get on their radar

than it is now. Lucky me!

I’ll never forget that afternoon when I got the email asking if I was interested in

writing this book. When I was pretty sure that no one was looking, I would break out

into this little happy dance for days. If only my high school English teacher could see

me now!

From that moment, I have considered it a great privilege to share with you the

things I’ve learned while building some large applications and writing untold lines of

AngularJS code. It’s been a most excellent journey, and I thank each and every one of

you for making this possible!

ABOUT THIS BOOK

xviii

Part 1, “Get acquainted with AngularJS,” introduces the high-level pieces of Angu-

larJS and talks about what each piece does and how they fit together (chapter 1). To

reiterate these concepts, we build out our first AngularJS application, a simplified ver-

sion of the main sample application, in chapter 2.

Part 2, “Make something with AngularJS,” gets into more advanced and specific top-

ics, such as server-side communication, directives, animations, routing, and forms and

validations. In each chapter, we look at the underpinnings of the topic and then see

how it appears in the context of a real application. We end each chapter with a discus-

sion on testing and best practices. Chapter 3 discusses how views and controllers work

together in AngularJS to control what the user sees, as well as capture user interactions

and convey those events for processing. Chapter 4 expands on controllers by introduc-

ing services and then showing how to communicate with a remote server using the

$http

service. Chapter 5 introduces directives and shows how directives turn layouts

into components while providing complex functionality. We’ll kick our layouts up a

notch in chapter 6 by adding in animations using

ngAnimate

. Chapter 7 digs into using

routes in AngularJS to deep-link to specific states in the application, preloading specific

data using

resolve

, and passing variables from route to route using

$routeParams

Chapter 8 finishes off with a discussion on how to use form validation to enhance the

user experience while providing safeguards around the data being entered.

There are also four appendixes about setting up Karma, setting up a Node.js

server, setting up a Firebase server, and running the sample app.

Source code conventions and downloads

The source code in the book, whether in code listings or snippets, is in a

fixed-width

font

this

, which sets it off from the surrounding text. In some listings, the code

is annotated to point out key concepts, and numbered bullets are sometimes used in

the text to provide additional information about the code. The code is formatted so

that it fits within the available page space in the book by adding line breaks and using

indentation carefully.

All of the source code for the examples in the book can be found at this Github

link: https://github.com/angularjs-in-action. The sample application for the book is

at this repository: https://github.com/angularjs-in-action/angello. The simplified

version of the application is at this repository: https://github.com/angularjs-in-

action/angello-lite.

You can also find detailed instructions on how to get the applications up and run-

ning in the readme file. Visit the repo often for updates and bug fixes to the project as

well as bonus repositories.

The source code is also available for download from the publisher’s website at

www.manning.com/AngularJSinAction.

NOTE At the time of this writing, Angular 2 is in an alpha release and not

yet ready for writing non-trivial applications. With that said, we’ll be pub-

lishing an Angular 2 version of Angello as soon as it makes sense.

ABOUT THIS BOOK

Software requirements

To run the sample applications, you’ll need to have Node.js installed. You can find the

installation instructions for Node.js at this link: https://nodejs.org/. To run the tests,

it’s also necessary to have Karma installed to execute the unit tests. You can find instruc-

tions on how to install Karma at their website: http://karma-runner.github.io/0.12/

index.html.

We also recommend installing the serve npm module, a lightweight web server to

display your web applications in the browser: https://www.npmjs.com/package/serve.
