Welcome to the angular cookbook. Here we will show you typical uses of angular by example.

## Hello World

Hello World: The simplest possible application that demonstrates the classic Hello World!

## Basic Form

Basic Form: Displaying forms to the user for editing is the bread and butter of web applications. Angular makes forms easy through bidirectional data binding.

## Advanced Form

Advanced Form: Taking the form example to the next level and providing advanced features such as dirty detection, form reverting and submit disabling if validation errors exist.

## Model View Controller

MVC: Tic-Tac-Toe: Model View Controller (MVC) is a time-tested design pattern to separate the behavior (JavaScript controller) from the presentation (HTML view). This separation aids in maintainability and testability of your project.

## Multi-page App and Deep Linking

Deep Linking: An AJAX application never navigates away from the first page it loads. Instead, it changes the DOM of its single page. Eliminating full-page reloads is what makes AJAX apps responsive, but it creates a problem in that apps with a single URL prevent you from emailing links to a particular screen within your application.

Deep linking tries to solve this by changing the URL anchor without reloading a page, thus allowing you to send links to specific screens in your app.

## Services

`Services`: Services are long lived objects in your applications that are available across controllers. A collection of useful services are pre-bundled with angular but you will likely add your own. Services are initialized using dependency injection, which resolves the order of initialization. This safeguards you from the perils of global state (a common way to implement long lived objects).

## External Resources

Resources: Web applications must be able to communicate with the external services to get and update data. Resources are the abstractions of external URLs which are specially tailored to angular data binding.
