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.

Debugging our code


Debugging tools are extremely important for a developer. It does not matter which programming language or framework you are using, or if you are working on either frontend or backend project. Debugging will always be present in your development process.

Nowadays, the web browser does more than just server pages, caching content, saving favorites, and so on. They are complete web development tools that provide awesome tools to debug our code and application performance.

Let's see how we can debug our code using our favorite web browser. We will use Chrome Developer Tools as an example.

Refactoring our application

First, we need to start our application and open it in a web browser. Let's use our aurelia-testapp:

$ cd aurelia-testapp
$ au run --watch

With the application up and running, head over to http://localhost:9000 to see the application. We will add a button and when the button is pressed, we will debug some dummy code. Open the info-box.html file and apply the following...
