Overview of this book

<p>AngularJS makes web JavaScript web development less painful and more organized – it’s unsurprising that today it’s one of the most popular tools in web development.</p> <p>AngularJS by Example helps you get started with this essential web development framework quickly and easily, guiding you through AngularJS by showing you how to create your own real-world applications. By adopting this approach, you can bridge the gap between learning and doing immediately, as you follow the examples to learn the impressive features of Angular and experience a radically simple–and powerful–approach to web development.</p> <p>You’ll begin by creating a simple Guess the Number game, which will help you get to grips with the core components of Angular, including its MVC architecture, and learn how each part interacts with one another. This will give you a solid foundation of knowledge from which you can begin to build more complex applications, such as a 7 minute workout app and an extended personal trainer app. By creating these applications yourself, you will find out how AngularJS manages client-server interactions and how to effectively utilize directives to develop applications further. You’ll also find information on testing your app with tools such as Jasmine, as well as tips and tricks for some of the most common challenges of developing with AngularJS.</p> <p>AngularJS by Example is a unique web development book that will help you get to grips with AngularJS and explore a powerful solution for developing single page applications.</p>

Chapter 5. Adding Data Persistence to Personal Trainer

It's now time to talk to the server! There is no fun in creating a workout, adding exercises, and saving it, to later realize that all our efforts are lost because the data is not persisted anywhere. We need to fix this.

Seldom are applications self-contained. Any consumer app, irrespective of the size, has parts that interact with elements outside its boundary. And with web-based applications, the interaction is mostly with a server. Apps interact with the server to authenticate, authorize, store/retrieve data, validate data, and perform other such operations.

This chapter explores the constructs that AngularJS provides for client-server interaction. In the process, we add a persistence layer to Personal Trainer that loads and saves data to a backend server.

The topics we cover in this chapter include:

  • Provisioning a backend to persist workout data: We set up a MongoLab account and use its REST API to access and store workout data.

  • Understanding...
