  This Developers Guide is a practical guide to Angular for experienced programmers who
 | 
						|
  are building client applications in HTML and Dart.

  We are on a journey together to understand how Angular works and, more importantly,
 | 
						|
  how to make it work for us. We look at our application requirements and we see problems to solve.
 | 
						|
  <br clear="all">
 | 
						|
 | 
						|
  * How do we get data onto the screen and handle user interactions?
 | 
						|
  * How do we organize our code into manageable, cohesive chunks of functionality that work together?
 | 
						|
  * What are the essential Angular building blocks and how do they help?
 | 
						|
  * How do we minimize routine, mechanical coding in favor of declarative, higher level constructs without losing control?
 | 
						|
 | 
						|
  This chapter begins the journey.

  # How to read this guide
 | 
						|
  Each chapter of this guide targets an Angular feature,
 | 
						|
  showing how to use it to solve a programming problem.
 | 
						|
 | 
						|
  All the chapters include code snippets ... snippets we can reuse in our own applications.
 | 
						|
  Typically, these snippets are excerpts from a sample application that accompanies the chapter.
 | 
						|
 | 
						|
  **All the source files** for each sample app are displayed together at the **end of each chapter.**
 | 
						|
 | 
						|
  <!-- Although a few early chapters are written as tutorials, most later chapters
 | 
						|
  don't explain how to build the accompanying sample.
 | 
						|
  These non-tutorial chapters highlight key points in code but generally don't include the entire source. -->
 | 
						|
 | 
						|
  <!-- We don't have to read this guide straight through. -->
 | 
						|
  <!-- The "[Cheat Sheet](cheatsheet.html)" is a handy map to Angular overall. -->
 | 
						|
  <!-- A few early chapters are arranged sequentially and best read together to establish a foundation in Angular.
 | 
						|
  But most chapters stand on their own. We can browse to any of them as our interest or some necessity moves us. -->
 | 
						|
 | 
						|
  Here is a learning path we might follow:
 | 
						|
 | 
						|
  1. First, be familiar with Dart programming and with web concepts such as
 | 
						|
  the DOM, HTML, and CSS. Dart tutorials such as
 | 
						|
  [Get Started](https://www.dartlang.org/docs/tutorials/get-started/) and
 | 
						|
  [Connect Dart & HTML](https://www.dartlang.org/docs/tutorials/connect-dart-html/)
 | 
						|
  are a great way to start.
 | 
						|
 | 
						|
  1. Follow the [QuickStart](../quickstart.html), which is the "Hello, World" of Angular 2.
 | 
						|
  It shows how to set up the libraries and tools needed to write *any* Angular app.
 | 
						|
  It ends with a "proof of life", a running Angular app.
 | 
						|
 | 
						|
  1. Next, read the Developers Guide chapters in order:
 | 
						|
    <!-- TODO: adjust this text once we have non-introductory/tutorial chapters -->
 | 
						|
    1. The rest of this chapter, especially the Architecture overview
 | 
						|
    1. [Displaying Data](displaying-data.html)
 | 
						|
    1. [User Input](user-input.html)
 | 
						|
    1. [Forms](forms.html)
 | 
						|
    <!-- add dependency injection when it exists -->
 | 
						|
    <!-- add text about template syntax, once that exists -->
 | 
						|
 | 
						|
  1. Consider hopping over to the [TypeScript docs](/docs/ts/latest/)
 | 
						|
     since they're currently ahead of the Dart docs. (We're working on that!)
 | 
						|
     Especially check out the [Tutorial](/docs/ts/latest/tutorial/) and
 | 
						|
     [Cheat Sheet](/docs/ts/latest/guide/cheatsheet.html), and the guide chapters
 | 
						|
     [Dependency Injection](/docs/ts/latest/guide/dependency-injection.html)
 | 
						|
     and [Template Syntax](/docs/ts/latest/guide/template-syntax.html).
 | 
						|
 | 
						|
  <!-- Follow your own star from there, wherever it leads. -->
 | 
						|
 | 
						|
  Don't miss the [Cheat Sheet](cheatsheet.html), a handy map to Angular.

  # Appendix: The Hero Staffing Agency
 | 
						|
 | 
						|
  There's a backstory to the <!-- the "Tour of Heroes" and --> samples in this guide.
 | 
						|
 | 
						|
  The world is full of crises large and small.
 | 
						|
  Fortunately, courageous heroes are prepared to take on every challenge.
 | 
						|
  The shadowy Hero Staffing Agency matches crises to heroes.
 | 
						|
 | 
						|
  We are contract developers, hired by the Agency to build an application to manage their operations.
 | 
						|
  The Agency maintains a stable of heroes with special powers.
 | 
						|
  Ordinary humans submit crises as job requests. The heroes bid to take the job, and the Agency
 | 
						|
  assigns each job accordingly.
 | 
						|
 | 
						|
  Our application handles every detail of recruiting, tracking, and job assignment.
 | 
						|
  For example, the [Forms](forms.html) chapter features a screen for
 | 
						|
  entering personal information about heroes:
 | 
						|
 | 
						|
figure.image-display
 | 
						|
