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>

Tracking exercise progress with audio clips


For our 7 Minute Workout app, adding sound support is vital. One cannot exercise while constantly staring at the screen. Audio clues will help the user to perform the workout effectively as he/she can just follow the audio instructions.

Here is how we are going to support exercise tracking using audio clues:

  • A ticking clock sound tracks the progress during the exercise

  • A half-way indicator sounds, indicating that the exercise is halfway through

  • An exercise-completion audio clip plays when the exercise is about to end

  • An audio clip plays during the rest phase and informs users about the next exercise

Modern browsers have good support for audio. The <audio> tag of HTML5 provides a mechanism to embed audio into our HTML content. We will use it to embed and play our audio clips during different times in the app.

AngularJS does not have any inherent support to play/manage audio content. We may be tempted to think that we can just go ahead and directly...
