Hands-On Full Stack Web Development with Aurelia

By: Diego Argüelles Rojas, Erikson Murrugarra

Overview of this book

Hands-On Full Stack Web Development with Aurelia begins with a review of basic JavaScript concepts and the structure of an Aurelia application generated with the Aurelia-CLI tool. You will learn how to create interesting and intuitive application using the Aurelia-Materialize plugin, which implements the material design approach. Once you fully configure a FIFA World Cup 2018 app, you'll start creating the initial components through TDD practices and then develop backend services to process and store all the user data. This book lets you explore the NoSQL model and implement it using one of the most popular NoSQL databases, MongoDB, with some exciting libraries to make the experience effortless. You'll also be able to add some advanced behavior to your components, from managing the lifecycle properly to using dynamic binding, field validations, and the custom service layer. You will integrate your application with Google OAuth Service and learn best practices to secure your applications. Furthermore, you'll write UI Testing scripts to create high-quality Aurelia Apps and explore the most used tools to run end-to-end tests. In the concluding chapters, you'll be able to deploy your application to the Cloud and Docker containers. By the end of this book, you will have learned how to create rich applications using best practices and modern approaches.

Binding custom behaviors to our application


Let's continue with our Aurelia special features exploration. In the last section, we saw value-converters, and it's impossible to not make a relationship between this feature and the binding engine of Aurelia framework. Maybe you think that both features have much in common, well, not so much really. Let's start explaining how the binding engine works.

The view resources in Aurelia framework can be divided into four categories:

  • Value converters
  • Custom attributes
  • Custom elements
  • Binding behaviors

We will focus only on the last one. It's not because the others are less important but because it will be better for us to understand how this works first and then explore the other categories. Don't worry, value-converters are already covered, and you will have a clearer idea about the difference between both features.

The value-converter acts just as a bridge interceptor between View and ViewModel (or vice versa). The binding behavior goes beyond—it has full...
