Angularjs Book Oreilly

With this book, you will soon be able to build client-side data driven applications. The introduction section covers the essentials of AngularJS, covering the core. Chapter 1. Introduction to AngularJS Our ability to create amazing web-based apps is incredible, but the complexity involved in making these apps is similarly. Like many others, I struggled to learn AngularJS in the beginning. This book was written to . Selling or distributing a CD-ROM of examples from O'Reilly books.

Now you can get everything with O'Reilly Online Learning. To download books, visit site or your favorite retailer. Some experience of modern tools such as Yeoman and Bower would be helpful, but is not a requirement. What You Will Learn Build and customize external HTML templates, and create simple, effective directives for common interface components Learn how to use Controller function and any Bootstrap UI directives to manipulate the DOM and how to transform any UI library into AngularJS directives Construct an AngularJS application to use shared components and validate your HTML5 Discover how to use jQuery events and manipulate the DOM using jQuery UI inside AngularJS applications Create custom directives for ongoing projects using Yeoman generators, and find out how to implement standalone directives Build reusable directives for Large AngularJS applications and extend directives to use dynamic templates Write unit test for directives using the Karma runner and Jasmine's behavior-driven development framework In Detail AngularJS directives are at the center of what makes it such an exciting — and important - web development framework. It makes building modern web applications a much more expressive experience, and allows you to focus more closely on improving the way that user interaction impacts the DOM and the way your app manages data. If you're already using Angular, you probably recognize the power of directives to transform the way you understand and build your projects — but customizing and creating your own directives to harness AngularJS to its full potential can be more challenging. This cookbook shows you how to do just that — it's a valuable resource that demonstrates how to use directives at every stage in the workflow. Packed with an extensive range of solutions and tips that AngularJS developers shouldn't do without, you'll find out how to make the most of directives. You'll find recipes demonstrating how to build a number of different user interface components with directives, so you can take complete control over how users interact with your application. You'll also learn how directives can simplify the way you work by creating reusable directives — by customizing them with Yeoman you can be confident that you're application has the robust architecture that forms the bedrock of the best user experiences.

We thought we might be able to use these experiences to benefit everyone. We wanted the coding process to feel more like creating and less like trying to satisfy the strange inner workings of web browsers. At the same time, we wanted an environment that helped us make the design choices that make apps easy to create and understand from the start, but that continue to be the right choices to make our apps easy to test, extend, and maintain as they grow large. A lot of credit goes to the open source community around Angular who do a fantastic job supporting each other and who have taught us many things.

Some of the larger and more involved examples and code snippets are available on a GitHub repository for you to look at, fork, and play with at our GitHub page. Client-Side Templates Multi-page web applications create their HTML by assembling and joining it with data on the server, and then shipping the finished pages up to the browser. Most single-page applications—also known as AJAX apps—do this as well, to some extent. Angular is different in that the template and data get shipped to the browser to be assembled there.

The role of the server then becomes only to serve as static resources for the templates and to properly serve the data required by those templates. Hello, World There are a few interesting things to note here in comparison with most methods in widespread use today: There are no classes or IDs in the HTML to identify where to attach event listeners.

When HelloController set the greeting. Why have we made these design choices and how does Angular work? From its start in Smalltalk, MVC became popular in nearly every desktop development environment where user interfaces were involved.

Until recently, however, MVC was all but foreign to web development. The core idea behind MVC is that you have clear separation in your code between managing its data model , the application logic controller , and presenting the data to the user view.

The view gets data from the model to display to the user. When a user interacts with the application by clicking or typing, the controller responds by changing data in the model. Finally, the model notifies the view that a change has occurred so that it can update what it displays. We think MVC is neat for several reasons.

Libraries like jQuery extended this model to the client and let us follow a similar style, but with the ability to update part of the DOM separately, rather than updating the whole page. This all works pretty well, but when you want to insert fresher data into the UI, or change the data based on user input, you need to do quite a bit of non-trivial work to make sure you get the data into the correct state, both in the UI and in JavaScript properties.

But what if we could have all this work done for us without writing code? What if we could just declare which parts of the UI map to which JavaScript properties and have them sync automatically?

AngularJS by Example

This style of programming is called data binding. Loading hello. There are a few interesting things to note here in comparison with most methods in widespread use today: Why have we made these design choices and how does Angular work? MVC application structure was introduced in the s as part of Smalltalk.

From its start in Smalltalk, MVC became popular in nearly every desktop development environment where user interfaces were involved.

The view gets data from the model to display to the user. When a user interacts with the application by clicking or typing, the controller responds by changing data in the model.

But what if we could have all this work done for us without writing code? What if we could just declare which parts of the UI map to which JavaScript properties and have them sync automatically? This style of programming is called data binding.

We included it in Angular because it works great with MVC to eliminate code when writing your view and model. Most of the work in moving data from one to the other just happens automatically.

As is, the HelloController sets the model greeting. Without ever registering a change listener on the input field, we have a UI that will dynamically update. The same would be true for changes coming to and from the server. Angular would automatically update both the input and the text in the curly braces to that value. Dependency injection lets us follow a development style in which, instead of creating dependencies, our classes just ask for what they need.

This follows a design pattern called the Law of Demeter , also known as the principle of least knowledge. Any objects or services that you end up creating can also be injected in the same way. Examples include the double-curly notation for data binding, ng-controller for specifying which controller oversees which part of the view, and ng-model , which binds an input to part of the model. We call these HTML extension directives.

Angular: Up and Running

Angular comes with many directives that help you define the view for your app. These directives can define what we commonly view as the template. They can declaratively set up how your application works or be used to create reusable components.

The rest of the book is dedicated to a more in-depth explanation. The ng-app attribute tells Angular which parts of the page it should manage.
